Description

  The present invention relates to a display control apparatus, a television, and a display control method for displaying an image on a display unit.

  As a display control apparatus of this type, a program viewing system including a mobile phone and a personal computer (hereinafter also referred to as “personal computer”) configured to be able to display a television program or the like is disclosed in Japanese Patent Laid-Open No. 2005-286661. Has been. In this program viewing system, when an operation for starting display of a TV program (hereinafter also referred to as “program”) is performed on a mobile phone, a predetermined program is displayed on the display unit of the mobile phone and the display is also performed. Information (broadcast station specifying information) that can specify the broadcast station of the started program is output from the mobile phone to a personal computer installed at home via a communication network. In response to this, the personal computer starts recording the same program as the program displayed on the mobile phone, and ends the recording of the program when a recording stop operation is performed by the user.

On the other hand, when an operation for stopping the display of a program is performed on the mobile phone, time information capable of specifying the time when the stop operation is performed is stored in an external storage medium (a storage medium connected to the mobile phone) of the mobile phone. Remembered. Also, in this program viewing system, the above external storage medium is removed from the mobile phone and attached to the personal computer, so that the program is played back from the portion where the display is stopped on the mobile phone based on the program image recorded by the personal computer. It is possible. Specifically, when the external storage medium is mounted, the personal computer specifies the time when the program display is stopped based on the time information stored in the external storage medium. Next, the personal computer reproduces (displays) the recorded program from the part at the specified time. As a result, the continuation of the program interrupted by the mobile phone can be viewed on the personal computer.
Japanese Patent Laying-Open No. 2005-286761 (pages 25-27, Fig. 1-3)

  However, the conventional program viewing system has the following problems. That is, in this program viewing system, the program image is continuously recorded by the personal computer until the recording stop operation is performed from the time when the display of the program is started on the mobile phone (when the broadcast station specifying information is output from the mobile phone). In addition, a configuration is adopted in which all programs (images) displayed on the mobile phone are recorded by a personal computer regardless of whether the display is interrupted or not. For this reason, it is necessary to connect a large-capacity storage device capable of storing a large amount of images for a long time to a personal computer. As a result, it is difficult to reduce the introduction cost of the conventional program viewing system. There is a problem.

  In addition, the conventional program viewing system employs a configuration in which, when an operation for stopping the display of a program is performed on a mobile phone, information capable of specifying the time is recorded in an external storage medium. Therefore, in the conventional program viewing system, when a call is received and the incoming call screen is displayed on the display unit while the program is being viewed on the mobile phone, the above operation for stopping the program display is performed. The time information is not stored in the external storage medium, and the state where viewing of the program is hindered by the incoming call screen is maintained. For this reason, the conventional program viewing system has a problem that it is difficult to find an image at a moment when viewing is interrupted by an incoming call from a large number of images recorded by a personal computer.

  The present invention has been made in view of such problems to be improved, and provides a display control device, a television set, and an information providing method capable of easily reproducing an image whose display is hindered while reducing the introduction cost. The main purpose is to do.

  In order to achieve the above object, a display control apparatus according to the present invention includes a control unit that displays an image on a display unit, and the first image is displayed in the state where the first image is displayed on the display unit. When an image display condition for displaying a second image of a different type on the display unit is satisfied, the control unit displays the second image on the display unit, and the first image is recorded on the recording device. To record.

  Note that “images of different types” in the present invention mean images of image signals with different input sources, and images of image signals output from different image signal output devices. In the present invention, “when the image display condition is satisfied” means that the display control device configured to display an image on the display unit according to the control signal from the external device indicates that the second image is displayed. In the display control device configured to display an image based on the image signal on the display unit when the image signal is output from the external device, the second image is displayed. When the image signal is output from an external device. Furthermore, in the state of “displaying the second image” in the present invention, the state in which the second image is displayed over the entire area of the display unit instead of the first image, and the first image is superimposed on the first image. Both states of displaying the two images on a part of the display unit are included.

  In addition, a television according to the present invention includes the above display control device and the display unit.

  In addition, the display control method according to the present invention is an image display in which a second image having a different type from the first image is displayed on the display unit in a state where the first image is displayed on the display unit. When the condition is satisfied, the second image is displayed on the display unit, and the first image is recorded on the recording device.

  According to the display control device, the television, and the display control method, the second image is displayed on the display unit and the second image is displayed when the image display condition is satisfied in a state where the first image is displayed on the display unit. By recording one image on the recording device, regardless of whether viewing is hindered due to an incoming call or the like, the recording is stopped by the user after the display of the TV program is started by the mobile phone. Unlike the conventional program viewing system in which the image of the television program is recorded by the personal computer for a long time until the operation is performed, the second image is displayed (for example, display of the videophone screen). Only when the display of the first image (for example, an image of a television program) is hindered due to the reason, the recording of the first image can be started from the part where the display is hindered. Storage unit that the storage capacity of (hard disk drive) can be sufficiently reduced. Therefore, since the recording apparatus can be configured without mounting a large-capacity storage unit, the introduction cost can be sufficiently reduced. In addition, since the recording of the first image is started from the time when the display is disturbed, the display is prevented without performing a complicated operation only by playing the recorded first image from the beginning. The first image can be displayed immediately from the site.

  Furthermore, in the display control device according to the present invention, the control unit is configured to receive an image output from a videophone, an image output from an interphone, an image for displaying received mail output from an e-mail receiving device, and an external device. At least one of the output message display images is displayed as the second image on the display unit when the image display condition is satisfied.

  According to this display control device, an image output from a videophone, an image output from an interphone, an image for displaying received mail output from an e-mail receiving device, and an image for displaying a message output from an external device By displaying at least one of the images as the second image on the display unit when the image display condition is satisfied, the display of the first image is prevented when these images are displayed on the display unit. The first image recorded in the recording device can be reproduced and reviewed later, so that the display of the first image is small so as not to be hindered by the display of each screen. The first image can be displayed sufficiently large on the display unit without adopting the configuration of displaying.

  Further, the display control device according to the present invention, when the image display condition is satisfied in a state where the image of the program broadcast as the first image is displayed on the display unit, the control unit An image of a program broadcast is recorded on the recording device.

  According to the display control device, when the image display condition is satisfied in a state where the program broadcast image as the first image is displayed on the display unit, the program broadcast image is recorded on the recording device. Unlike the playback of video content recorded on an optical recording medium or the like, a second image (for example, a videophone image) is displayed during viewing of a program broadcast that is difficult to watch the same scene retroactively. Even if displayed on the screen, by playing back the first image recorded by the recording device, it is possible to reliably view a scene that has been prevented from being viewed due to the display of the second image.

  Furthermore, in the display control device according to the present invention, the control unit acquires the broadcast end time of the program broadcast of the first image that is recorded by the recording device from the electronic program information, and the acquired broadcast When the end time arrives, the recording of the first image by the recording device is ended.

  According to this display control device, the broadcast end time of the program broadcast of the first image recorded in the recording device is acquired from the electronic program information, and when the acquired broadcast end time arrives, Unlike the configuration in which the recording of the first image is stopped by, for example, operating the operation unit of the recording device to stop the recording of the first image, the unnecessary recording of the first image is continued without forgetting the stop operation. Can be avoided. Therefore, according to the display control apparatus, the storage capacity of the storage unit required for the recording apparatus can be further reduced, and the introduction cost can be further reduced. Moreover, the situation where the recording area of the storage unit in the recording apparatus is unnecessarily consumed can be avoided by recording the first image that does not require recording.

  Further, the display control device according to the present invention is configured such that when a display resumption condition for resuming display of the first image is satisfied in a state where the recording device records the first image, the control unit However, the recording of the first image by the recording device is ended.

  According to this display control apparatus, when the display restart condition is satisfied in a state where the recording apparatus is recording the first image, the recording of the first image by the recording apparatus is ended, for example, the recording apparatus Unlike the configuration in which the operation unit is operated to stop the recording, it is possible to avoid a situation in which the recording of the unnecessary first image is continuously executed because the stop operation is forgotten. Therefore, according to the display control apparatus, the storage capacity of the storage unit required for the recording apparatus can be further reduced, and the introduction cost can be further reduced. Moreover, the situation where the recording area of the storage unit in the recording apparatus is unnecessarily consumed can be avoided by recording the first image that is no longer required to be recorded when the display is resumed.

  Hereinafter, the best mode of a display control device, a television, and a display control method according to the present invention will be described with reference to the accompanying drawings. A television 1 shown in FIG. 1 is a rear projection type television (display device) in which a display control device according to the present invention and a display unit according to the present invention are integrated, and includes a recording / playback device 2 and a personal computer 3. (Hereinafter also referred to as “PC 3”), the intercom 4 and the home appliance 5 are configured to be connectable. In this case, the recording / reproducing apparatus 2 corresponds to the recording apparatus in the present invention, and includes a storage unit 2a composed of a large-capacity storage device such as a hard disk drive, and can record (reproduce images) and reproduce various image signals. It is configured to be possible.

  The personal computer 3 constitutes a video phone and an e-mail receiving device according to the present invention, is connected to the Internet 3a, and is installed with video phone software (IP phone software having a bidirectional video playback function), e-mail software, and the like. ing. Further, as will be described later, the personal computer 3 receives the control signal S6a and the image signal S6 when the telephone call is received via the Internet 3a (when the call signal S5 is received via the Internet 3a). The videophone screen 22 for telephone call (see FIG. 4) is displayed by outputting to the mobile phone. Further, the personal computer 3 monitors a preset e-mail server, and when an e-mail arrives, the personal computer 3 displays a message screen for notifying that fact or a mail display screen for displaying a received mail (for “reception mail display” in the present invention). Screen ”(not shown) is displayed on the television 1.

  The intercom 4 includes a call switch, a camera, and a microphone. As an example, the interphone 4 is disposed at the entrance of a house where the television 1 is installed. When the call switch is operated, the intercom 4 outputs a control signal S7a and an image signal S7 to the television 1 so that an image (not shown) captured by the camera is displayed on the television 1. The home appliance 5 is, for example, a washing machine, and outputs a control signal S8a and an image signal S8 toward the television 1 when washing is finished, thereby displaying a message display screen 23 (indicating that washing is finished). 5) is displayed.

  On the other hand, the television 1 includes a tuner 11, an electronic program information acquisition unit 12, an image processing unit 13, a display unit 14, and a control unit 15. As an example, the tuner 11 receives various broadcast waves S1 such as terrestrial analog broadcast, terrestrial digital broadcast, CS broadcast, and BS broadcast, generates a broadcast signal S2, and generates the broadcast signal S2 by the control unit 15 or a recording / playback device. Output to 2. It is also possible to employ a configuration in which the tuner 11 configured separately from the main body is connected to the main body without incorporating the tuner 11 in the main body of the television 1. As an example, the electronic program information acquisition unit 12 acquires electronic program information (EPG (Electric Program Guide) information) Dp from the broadcast wave S <b> 1 received by the tuner 11. The image processing unit 13 performs signal processing on the broadcast signal S2 output from the tuner 11 and the image signals S6 to S8 output from the personal computer 3, the intercom 4, and the home appliance 5, thereby displaying various display screens on the display unit 14. An image signal S3 to be displayed on the screen is generated and output.

  The display unit 14 includes an optical engine, a screen panel, and the like (not shown), and displays various image display screens based on the image signal S3 output from the image processing unit 13 (the program viewing screen 21 shown in FIG. 2 and FIG. 4). Video phone screen 22 shown, message display screen 23 shown in FIG. 5 and the like). Specifically, the display unit 14 displays various images on the screen panel by projecting projection light light-modulated based on the image signal S3 onto the screen panel from the back side. In this case, the optical engine includes, for example, a light source, a light modulation element (for example, a digital micromirror device or a liquid crystal light valve), and a projection lens (both not shown).

  The control unit 15 comprehensively controls the television 1. Specifically, the control unit 15 controls the tuner 11 to receive a broadcast wave S1 of a predetermined channel. In addition, the control unit 15 outputs the broadcast signal S2 output from the tuner 11 to the image processing unit 13 to display the program viewing screen 21 on the display unit 14. Furthermore, the control unit 15 outputs the image signal S6 to the image processing unit 13 according to the control signal S6a output from the personal computer 3, thereby causing the display unit 14 to display the videophone screen 22 instead of the program viewing screen 21 and the like. At the same time, the tuner 11 is controlled to output the broadcast signal S2 to the recording / reproducing apparatus 2. In addition, the control unit 15 outputs an image signal S7 to the image processing unit 13 in accordance with the control signal S7a output from the intercom 4, so that an image (not shown) based on the image signal S7 instead of the program viewing screen 21 or the like. Is displayed on the display unit 14, and the tuner 11 is controlled to output the broadcast signal S 2 to the recording / playback apparatus 2.

  Further, the control unit 15 outputs the image signal S8 to the image processing unit 13 in accordance with the control signal S8a output from the home appliance 5 so that the message display screen 23 based on the image signal S8 is superimposed on the program viewing screen 21 or the like. While being displayed on the display unit 14, the tuner 11 is controlled to output the broadcast signal S 2 to the recording / playback apparatus 2. Further, the control unit 15 specifies the broadcast end time of the program broadcast in which the recording / playback apparatus 2 records the broadcast signal S2 based on the electronic program information Dp acquired by the electronic program information acquisition unit 12, and the specified time When the video signal arrives, the recording / playback apparatus 2 is controlled to stop recording. Further, for example, when the call through the personal computer 3 is completed, the control unit 15 displays the program viewing screen 21 on the display unit 14 instead of the videophone screen 22 and controls the recording / reproducing apparatus 2 to broadcast. Recording of the signal S2 is stopped.

  Next, the overall operation of the television 1 will be described with reference to the drawings. When viewing a television program on the television 1, the television 1 is turned on by operating a power switch of a remote controller (not shown). At this time, the tuner 11 receives the broadcast wave S1 of the channel that was selected at the time of the previous power-off under the control of the control unit 15, and outputs the broadcast signal S2. In response to this, the control unit 15 outputs the broadcast signal S2 to the image processing unit 13, and the image processing unit 13 generates the image signal S3 based on the broadcast signal S2 and outputs it to the display unit 14. As a result, the program viewing screen 21 is displayed on the screen panel of the display unit 14 as shown in FIG. The electronic program information acquisition unit 12 acquires the electronic program information Dp from the broadcast wave S <b> 1 received by the tuner 11 under the control of the control unit 15.

  Further, the control unit 15 starts the display control process 30 shown in FIG. 3 together with the output of the broadcast signal S2 to the image processing unit 13 (the display of the program viewing screen 21 starts). In the display control process 30, the control unit 15 monitors whether or not a control signal instructing display of external content has been output (step 31). In this case, in the television 1, a television image based on the broadcast signal S 2 output from the tuner 11 is displayed on the display unit 14 as internal content (first image in the present invention) and a video phone output from the personal computer 3. Images for receiving and displaying received mail (images based on the image signal S6), images output from the intercom 4 (images based on the image signal S7), and images for displaying messages output from the home appliance 5 (images) A configuration is adopted in which an image based on the signal S8 is displayed on the display unit 14 as external content (second image in the present invention). At this time, when a videophone call arrives on the personal computer 3 via the Internet 3a (when a call signal S5 is output from the base station of the videophone), an image signal S6 for displaying a call screen is displayed. A control signal S6a for instructing display of an image based on the image signal S6 is output from the personal computer 3.

  At this time, the control unit 15 of the television 1 determines that the image display condition in the present invention is satisfied, and outputs the image signal S6 output from the personal computer 3 to the image processing unit 13. In response to this, the image processing unit 13 generates an image signal S3 based on the image signal S6 and outputs it to the display unit 14. As a result, as shown in FIG. 4, the videophone screen 22 is switched to the screen panel of the display unit 14 instead of the program viewing screen 21 (step 32). Next, the control unit 15 controls the tuner 11 to output the broadcast signal S2 of the program viewing screen 21 that has been displayed on the display unit 14 before the videophone screen 22 is switched and displayed to the recording / playback apparatus 2. At the same time, the control signal S4 is output to the recording / reproducing apparatus 2 to start recording the broadcast signal S2 output from the tuner 11 (step 33). As a result, the program broadcast image (broadcast signal S 2) whose viewing is hindered by the display of the videophone screen 22 is recorded by the recording / playback apparatus 2.

  Subsequently, the control unit 15 specifies the broadcast end time of the program broadcast in which the recording / playback apparatus 2 records the broadcast signal S2 based on the electronic program information Dp acquired by the electronic program information acquisition unit 12 (step 34). ). Next, the control unit 15 determines whether or not the specified broadcast end time has arrived (step 35). At this time, when it is determined that the broadcast end time has arrived, the control unit 15 controls the tuner 11 to stop the output of the broadcast signal S2 to the recording / reproducing apparatus 2 and also causes the recording / reproducing apparatus 2 to control the control signal S4. Is output to stop the recording of the broadcast signal S2 (step 36), and the display control process 30 ends. This completes recording of the broadcast signal S2 (television image recording) from the time of the incoming call to the end of broadcast of the program broadcast.

  On the other hand, when it is determined that the broadcast end time has not arrived (step 35), the control unit 15 displays the external content (in this example, a videophone image output from the personal computer 3: the videophone screen 22). It is monitored whether there is an instruction to end (step 37). At this time, when the videophone call is finished, the personal computer 3 stops outputting the image signal S6 to the television 1 and outputs a control signal S6a indicating that the call is finished to the television 1. In response to this, the control unit 15 determines that there is an instruction to end the display of the external content (an instruction to redisplay the internal content displayed on the display unit 14 before displaying the external content), and The processing unit 13 is controlled to end the display of the videophone screen 22, and the program viewing screen 21 is displayed on the display unit 14 (step 38).

  Next, the control unit 15 controls the tuner 11 to stop the output of the broadcast signal S2 to the recording / playback apparatus 2 and outputs the control signal S4 to the recording / playback apparatus 2 to stop the recording of the broadcast signal S2. (Step 36), the display control process 30 is terminated. This completes recording of the broadcast signal S2 (television image recording) from the time of the incoming call to the end of the call. It is also possible to adopt a configuration in which recording is continued until the broadcast end time arrives without immediately ending the recording of the broadcast signal S2 by the recording / playback apparatus 2 when the call is completed.

  In the television 1, when the call switch of the intercom 4 is operated by a visitor while the program viewing screen 21 is displayed on the display unit 14, the image signal S 7 and the control signal are transmitted from the intercom 4 to the television 1. S7a is output. At this time, the control unit 15 determines that the image display condition in the present invention is satisfied in the same manner as when the image signal S6 and the control signal S6a are output from the personal computer 3 described above (instructs display of external content). The control signal S7a to be output is determined: Step 31), the image signal S7 output from the intercom 4 is output to the image processing unit 13 to generate the image signal S3, and the image based on the image signal S3 (interphone 4) An image captured by the camera (not shown) is displayed on the display unit 14 (step 32). Next, the control unit 15 controls the tuner 11 to output the broadcast signal S2 to the recording / reproducing apparatus 2 and outputs the control signal S4 to the recording / reproducing apparatus 2 to start recording of the broadcast signal S2. (Step 33). As a result, an image of the program broadcast whose viewing is hindered by the display of the image captured by the camera of the interphone 4 is recorded by the recording / playback apparatus 2.

  Subsequently, the control unit 15 specifies the broadcast end time of the recorded program broadcast based on the electronic program information Dp (step 34), and controls the tuner 11 when the broadcast end time arrives (step 35). Then, the output of the broadcast signal S2 is stopped, and the control signal S4 is output to the recording / playback apparatus 2 to stop the recording of the broadcast signal S2 (step 36). This completes the recording of the broadcast signal S2 from the time when the call switch is operated until the end of the program broadcast. When the visitor leaves before the broadcast end time arrives (imaging by the camera of the intercom 4 is terminated), the intercom 4 stops outputting the image signal S7 to the television 1 and the camera captures the image. A control signal S7a indicating the completion is output to the television 1.

  In response to this, the control unit 15 determines that there is an instruction to end the display of the external content (an instruction to re-display the internal content displayed on the display unit 14 before displaying the external content) (Step S15). 37) The image processing unit 13 is controlled to end the display of the image based on the image signal S7, and the program viewing screen 21 is displayed on the display unit 14 (step 38). Next, the control unit 15 stops the output of the broadcast signal S2 to the recording / playback apparatus 2 by controlling the tuner 11, and stops the recording of the broadcast signal S2 by outputting the control signal S4 to the recording / playback apparatus 2. (Step 36). Thereby, recording of the broadcast signal S2 (recording of the television image) from the time when the visitor operates the call switch to the time when the display of the image captured by the camera of the intercom 4 is completed is completed.

  Further, in the television 1, when the washing with the home appliance 5 (in this example, a washing machine) is completed in a state where the program viewing screen 21 is displayed on the display unit 14, an image is displayed from the home appliance 5 to the television 1. Signal S6 and control signal S8a are output. At this time, the control unit 15 determines that the image display conditions in the present invention are satisfied in the same manner as when the image signals S6 and S7 and the control signals S6a and S7a are output from the personal computer 3 and the interphone 4 described above. (It is determined that the control signal S7a instructing display of the external content has been output: Step 31), and the image signal S8 output from the home appliance 5 is output to the image processing unit 13 to generate the image signal S3. At this time, the image processing unit 13 generates the image signal S3 based on the broadcast signal S2 output from the tuner 11 and the image signal S8 output from the home appliance 5 as shown in FIG. As an example, a message display screen 23 showing a message “Laundry has been completed” is superimposed on the program viewing screen 21 and displayed as a pop-up on the display unit 14 (step 32).

  Next, the control unit 15 controls the tuner 11 to output the broadcast signal S2 to the recording / reproducing apparatus 2 and outputs the control signal S4 to the recording / reproducing apparatus 2 to start recording of the broadcast signal S2. (Step 33). Thereby, a part of the program viewing screen 21 is blocked by the display of the image (message display screen 23) based on the image signal S8 output from the home appliance 5, and the program broadcast image whose viewing is blocked is recorded and reproduced. Recorded by device 2. Subsequently, the control unit 15 specifies the broadcast end time of the recorded program broadcast based on the electronic program information Dp (step 34), and controls the tuner 11 when the broadcast end time arrives (step 35). Then, the output of the broadcast signal S2 is stopped, and the control signal S4 is output to the recording / playback apparatus 2 to stop the recording of the broadcast signal S2 (step 36). Thereby, recording of the broadcast signal S2 (recording of a television image) from the time when washing is completed (when the message display screen 23 is pop-up displayed) to the time when the broadcast of the program broadcast ends is completed.

  When the user who viewed the message display screen 23 operates the remote controller to close the message display screen 23, the control unit 15 instructs to end the display of the external content (before displaying the external content). It is determined that there is an instruction to redisplay the internal content displayed on the display unit 14 (step 37), and the image processing unit 13 is controlled to end the display of the message display screen 23 based on the image signal S8. Thus, the program viewing screen 21 is displayed on the entire display unit 14 (step 38). Next, the control unit 15 stops the output of the broadcast signal S2 to the recording / playback apparatus 2 by controlling the tuner 11, and stops the recording of the broadcast signal S2 by outputting the control signal S4 to the recording / playback apparatus 2. (Step 36). Thereby, recording of the broadcast signal S2 from the time when the washing is completed (when the message display screen 23 notifying that the washing is completed) to the time when the operation for closing the message display screen 23 is performed (television image). Recording) is completed.

  On the other hand, a program whose viewing is hindered by the display of the videophone screen 22 for videophone, the display of the image captured by the camera of the intercom 4 and the display of the message display screen 23 for displaying the message output from the home appliance 5 When viewing a broadcast image, for example, a remote control (not shown) of the recording / reproducing apparatus 2 is operated to reproduce the broadcast signal S2 recorded (recorded) in the storage unit 2a. At this time, in the recording / reproducing apparatus 2, an image reproduction processing unit (not shown) reads the recording data of the broadcast signal S2 from the storage unit 2a to generate the image signal S9, and outputs the generated image signal S9 to the television 1. In response to this, the control unit 15 outputs the image signal S9 output from the recording / playback apparatus 2 to the image processing unit 13. Further, the image processing unit 13 generates an image signal S3 based on the image signal S9 and outputs the image signal S3 to the display unit 14. As a result, an image of the program broadcast whose viewing is hindered by the display of the external content is displayed on the screen panel of the display unit 14.

  Thus, according to the television 1 and the display control method using the television 1, the first image (in this example, the image based on the broadcast signal S2 output from the tuner 11: the program viewing screen 21) is displayed on the display unit 14. When the image display condition in the present invention is satisfied in the displayed state, the second image (for example, an image based on the image signal S3 output from the personal computer 3: the videophone screen 22) is displayed on the display unit 14. By displaying the first image (broadcast signal S2) on the recording / playback apparatus 2, the mobile phone can display a TV program regardless of whether viewing is hindered due to an incoming call or the like. A conventional program having a configuration in which an image of a television program is recorded by a personal computer over a long period of time after the start until the user performs an operation to stop recording. Unlike the listening system, only when viewing of a TV program (display of the program viewing screen 21) is hindered due to an incoming videophone call or the like, recording of the broadcast signal S2 (TV image) from the part where viewing is hindered Recording) can be started, the storage capacity of the storage unit 2a required for the recording / reproducing apparatus 2 can be made sufficiently small. Accordingly, since the recording / playback apparatus 2 can be configured without mounting a large-capacity storage unit, the introduction cost can be sufficiently reduced. In addition, since the recording of the broadcast signal S2 is started when viewing of the TV program (display of the program viewing screen 21) is hindered, it is possible to perform a complicated operation only by playing the recorded broadcast signal S2 from the beginning. It is possible to immediately watch a television program or the like from a portion where viewing has been hindered without performing it.

  In addition, according to the television 1, an image (image based on the image signal S6: video phone screen 22) output from the video phone (in this example, the personal computer 3), an image output from the intercom 4 (image signal S7). Image), an e-mail receiving device (in this example, the personal computer 3), an incoming mail display image (image based on the image signal S6), and an external device (in this example, the home appliance 5). When at least one of the received message display images (image based on the image signal S8: message display screen 23) is the second image in the present invention, the above-mentioned image display condition is satisfied. Even if the display of the program viewing screen 21 (viewing of a TV program) is hindered by displaying these images on the display unit 14, Since the broadcast signal S2 recorded in the recording / playback apparatus 2 can be reproduced and the image thereof can be reviewed, the display of the program viewing screen 21 is small so as not to be hindered due to the display of each screen described above. The videophone screen 22 and the like can be displayed sufficiently large on the display unit 14 without adopting a configuration such as.

  Furthermore, according to the television 1, an image of a program broadcast as a first image in the present invention (in this example, an image based on the broadcast signal S2 output from the tuner 11: the program viewing screen 21) is displayed on the display unit 14. Video content recorded on an optical recording medium or the like by causing the recording / playback apparatus 2 to record a program broadcast image (broadcast signal S2) when the image display conditions in the present invention are satisfied in the displayed state. Unlike video playback, even if the videophone screen 22 is displayed on the display unit 14 due to an incoming videophone call or the like during viewing of a TV program that is difficult to watch the same scene retroactively, video recording and playback are possible. By reproducing the broadcast signal S2 recorded by the device 2, it is possible to reliably view a scene in which viewing is hindered due to the display of the videophone screen 22.

  Further, according to the television 1, the broadcast end time of the program broadcast of the first image (the image based on the broadcast signal S2: the program viewing screen 21) recorded in the recording / playback apparatus 2 is acquired from the electronic program information Dp. At the same time, when the acquired broadcast end time arrives, the recording of the first image (broadcast signal S2) by the recording / playback apparatus 2 is ended, for example, the operation unit of the recording / playback apparatus 2 is operated to stop the recording. Unlike the configuration in which the recording operation is performed, it is possible to avoid a situation in which the stop operation is forgotten and the recording of the unnecessary broadcast signal S2 is continuously performed. Therefore, according to the television 1, since the storage capacity of the storage unit 2a required for the recording / playback apparatus 2 can be further reduced, the introduction cost can be further reduced. Moreover, it is possible to avoid a situation in which the recording area of the storage unit 2a in the recording / playback apparatus 2 is unnecessarily consumed by recording the broadcast signal S2 that does not require recording.

  Further, according to the television 1, when the display resumption condition in the present invention is satisfied in a state where the recording / playback apparatus 2 records the first image in the present invention, the first image by the recording / playback apparatus 2 is satisfied. For example, unlike the configuration in which recording is stopped by operating the operation unit of the recording / playback apparatus 2, the recording of the unnecessary broadcast signal S2 is continuously executed without forgetting the stop operation. Can be avoided. Therefore, according to the television 1, since the storage capacity of the storage unit 2a required for the recording / playback apparatus 2 can be further reduced, the introduction cost can be further reduced. In addition, the recording area of the storage unit 2a in the recording / playback apparatus 2 is unnecessarily consumed by recording an image (broadcast signal S2) that is no longer required to be recorded with the resumption of display of the program viewing screen 21 and the like. Can be avoided.

  In addition, this invention is not limited to said structure. For example, although the television 1 provided with the rear projection type display unit 14 has been described above, the display unit in the present invention can be configured by various displays such as a liquid crystal display, a plasma display, and an organic EL display. Further, the display device (TV 1) in which the display control device according to the present invention and the display unit according to the present invention are integrated has been described. However, the display unit according to the present invention is separate from the display control device according to the present invention. It is also possible to adopt a configuration in which the above-described program viewing screen 21 or the like is displayed on the display unit as an external device. Specifically, the display control apparatus according to the present invention can be applied to various audiovisual devices (for example, various recorders, players, decoders, tuners, etc.) that do not include a display unit.
