Description

  The present invention relates to a video reproduction method and apparatus for reproducing a video signal.

  In many television broadcasts, for example, terrestrial private broadcasters, private companies recruit program sponsors to provide programs, operate broadcast services based on the sponsor fees and advertising fees, and broadcast programs free to general viewers Is provided. Therefore, it is common to insert a commercial message (hereinafter CM) at the beginning, middle or end of the provided program.

  With the spread and improvement of functions of home video recorders, there are an increasing number of viewing methods for recording broadcast programs and viewing the recorded broadcast programs later. When viewing a broadcast program recorded in this way, the viewer has a desire to skip the CM inserted at the beginning or middle of the program and view it. Since recent video recorders use a randomly accessible recording medium such as a hard disk or an optical disk, those equipped with a function for skipping CMs with a simple operation are increasing.

  Under these circumstances, when viewing a recorded broadcast program, the opportunity to view commercials in the broadcast program has decreased sharply, making it impossible for program sponsors to obtain sufficient advertising effects commensurate with the advertising fee. There is a possibility that the broadcast program form does not hold.

  In order to deal with these problems, CM data received as a data broadcast is stored in the receiver, and the CM viewing time in the normal broadcast is measured. A broadcasting system for displaying CM data has been proposed (see Patent Document 1).

In addition, a broadcasting system has been proposed in which display frequency information is added to a broadcast program signal and a CM is forcibly viewed on the receiving side until the number of display times of the display frequency information is displayed (see Patent Document 2).

  The techniques described in Patent Document 1 and Patent Document 2 both require new information to be transmitted in addition to the current broadcast form, and are difficult to realize with the current program provision form. Also, from the viewpoint of the viewer, it is not always necessary to skip the CM, and there are many cases where it is desired to view it intentionally if it is a CM that suits individual tastes.

  Therefore, according to the present invention, even if the CM is skipped, the viewer can partially watch the CM, and if it is attractive to the viewer by having the viewer watch it, It is an object of the present invention to present a video reproduction method and apparatus that can be easily viewed by presenting an original CM to a viewer.

  The video playback method according to the present invention is a video playback method for playing back video content including a CM video between main video images, the step of referring to playback information including the playback count of the video content, With respect to the CM skip detection step for detecting the skip operation and the CM skip operation in the case where the number of times the video content is reproduced is less than a predetermined value, the playback video of the video content after the skip according to the skip operation is displayed. And a multiplexing step for multiplexing the reproduced video of the CM video that is the target of the skip operation.

  A video playback apparatus according to the present invention is a video playback apparatus that plays back video content including CM video between main video, and includes playback information recording means for recording playback information including the number of playback times of the video content, By a playback apparatus capable of selectively executing independent playback for independent display of video content and simultaneous playback of simultaneously playing back and multiplexing the video content and the CM video, skip operation means, and skip operation means CM skip detection means for detecting whether or not the skip operation is for a CM video, and the playback device for the CM skip operation during the single playback when the playback count of the video content is less than a predetermined value. Control means for executing multiple display by the simultaneous reproduction of the CM video that is the target of the CM skip operation. Characterized in that it Bei.

  According to the present invention, even when a skip operation is performed on a CM video inserted in a program, the CM video is multiplexed with the playback video after skipping, thereby allowing the viewer to view the CM video. It is possible to watch and listen to. In addition, by making it possible to selectively reproduce the CM video displayed in a multiplexed manner, in the case of a CM video that matches the taste of the viewer, the CM video can be easily selected and reproduced for viewing.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 shows a schematic block diagram of a video reproducing apparatus according to the first embodiment of the present invention.

  The operation unit 16 is a controller for the video reproduction device 10, and the control device 18 controls the operation of the video reproduction device 10 based on a signal transmitted from the operation unit 16 by a user operation. The operation unit 16 includes a skip button for skipping recorded video and menu buttons for performing various operations and settings in addition to operation keys for instructing recording / playback.

  The tuner 14 extracts a video / audio signal of a designated channel from the television broadcast signal received by the antenna 12. The content detection device 20 detects the switching point between the CM and the program in accordance with the audio multiplexing mode (stereo, monaural, or bilingual) of the video / audio signal from the tuner 14, and index information at the time of reproduction indicating the switching point. If it is determined that the content is a CM, CM content information indicating that the content is a CM is transmitted to the control device 18. The content detection apparatus 20 also supplies the input video / audio signal to the recording / playback processing apparatus 22 as it is.

  The control device 18 supplies system data including index information and CM content information to the recording / playback processing device 22. The recording / playback processing device 22 records and plays back the video / audio signal from the content detection device 20 and the system data from the control device 18 on the recording medium 24. The recording medium 24 is a randomly accessible recording medium such as an optical disk or a magnetic disk. Specifically, it consists of a hard disk, a recordable optical disk, or a semiconductor memory.

  The recording / playback processing device 22 includes a playback video resizing processing device 22a. The playback video resizing processing device 22a can convert the playback video to an arbitrary size set by the control device 18 and output it to the video processing device 26 from either of the two video signal outputs of video 1 and video 2. The video processing device 26 outputs the video signal supplied from the tuner 14 or the recording / playback processing device 22 to the display device 28. The video processing device 26 has a function of multiplexing and displaying two video signals of video 1 and video 2 supplied from the recording / playback processing device 22. For example, multiple display is possible in which video 1 is used as the base display layer and video 2 is overlaid on the display layer.

  The video playback device 10 has a function of updating and holding the number of playbacks for each content during playback, and is recorded on the recording medium 24 in association with each content as playback information consisting of 4 bits shown in FIG. The most significant 1 bit of the reproduction information indicates the above-described CM content information. When this bit is “1”, it indicates that the content is CM content. When it is determined that the content is CM at the time of recording, 1 'is set. The lower 3 bits indicate the number of times of reproduction, and the number of times of reproduction from 0 to 7 can be stored. The control device 18 obtains the number-of-plays information from the recording medium 24 via the recording / playback device 22 at the start of content playback.

  FIG. 3 shows a procedure for updating the number-of-plays information. With reference to the flowchart shown in FIG. 3, a procedure for updating the number of reproduction times information will be described.

  When a playback instruction is input from the operation unit 16, the control device 18 acquires playback count information from the playback information recorded in association with the content to be played back (S1). In the case of unreproduced content, the number of reproductions is zero.

  When the next content is reached during playback (S3), the currently acquired playback count information is incremented and updated, and written back to the storage medium 24 as playback information (S4). When the number of reproductions is 7 or more, the number of reproductions is not incremented any more and is maintained as 7.

  The above processing (S1, S3, S4) is repeated until an instruction to stop reproduction is given (S2).

  In this way, the number of reproductions of the reproduced content is counted until the upper limit value is reached, and the reproduction number information is held in the recording medium 24.

  When a skip instruction is input from the operation unit 16 during playback and the skip target is CM, the control device 18 is instructed to skip to the skipped playback content (content 1) as shown in FIG. The video overlaid with the CM content (content 2) is displayed on the screen of the display device 28. FIG. 5 shows a flowchart of the process.

  When the reproduction is started, the control device 18 first obtains reproduction information recorded in association with the content to be reproduced (S11). In the case of unreproduced content, the number of reproductions in the reproduction information is zero.

  Normally, since two images are not being displayed in a multiplexed manner (S12), a reproduction stop instruction (S18) or a CM skip instruction (S19) is awaited.

  When a ticket instruction is input from the operation unit 16 during reproduction, and the skip target is determined to be CM from CM content information in the reproduction information of the content (S19), the control device 18 acquires the reproduced information. The display time is calculated from the information on the number of times of reproduction in accordance with the prior setting (S20). For example, the display time when the number of times of playback is 0 is 15 seconds, the display time when the number of times of playback is 1 time is 10 seconds, the display time when the number of times is 2 times, 5 seconds, the display time of 3 times or more is 0 seconds And Of course, other settings between displays are also possible.

  The control device 18 instructs the recording / playback processing device 22 and the video processing device 26 to multiplex display the calculated CM content during the calculated display time (S21). The recording / playback processing unit device 22 simultaneously outputs the playback video (video 1) of the content after skipping and the playback video (video 2) of the CM content targeted for skipping to the video processing device 26. 4 generates a video signal obtained by overlaying video 1 (content 1) and video 2 (content 2) as shown in FIG. As a result, the CM content is multiplexed and displayed on the original content. When, for example, three CM contents are skipped by continuous skipping, the recording / playback processing device 22 configures three content playback videos on the same layer as shown in FIG. Can also be output.

  During the multiple display, the multiple display time from the start of the multiple display is measured. While the multiple display is being performed, there is no CM playback instruction (S13), and when the display time calculated in step S20 has elapsed (S16), the control device 18 includes the recording / playback processing device 22 and the video processing device 26. Is instructed to stop multiple display (S17). In response to this instruction, the recording / playback processing device 22 stops the output of the video 2, and the video processing device 26 applies only the video signal of the video 1 of the recording / playback processing device 22 to the display device 28.

  The CM content display frame during multiple display is highlighted as shown in FIG. When the user gives an instruction to reproduce the CM content being multiplexed and displayed by the operation unit 16 during the multiple display (S13), the control device 18 stops the multiple display and selects and reproduces the CM content. The processing device 26 is instructed (S14). In response to these instructions, the recording / playback processing device 22 stops the output of the video 2, plays the corresponding CM content from the recording medium 24, and outputs it as the video 1 to the video processing device. The synthesis for the multiple display of the videos 1 and 2 is stopped, and the video signal of the video 1 from the recording / playback processing device 22 is supplied to the display device 28 (S15). As a result, the selected CM is reproduced and displayed on the full screen.

  During the above processing, when the user gives an instruction to stop playback through the operation unit 16 (S18), the control device 18 instructs the recording / playback processing device 22 to stop playback of the corresponding content, and the recording / playback processing device 22 Reading of the recording information of the corresponding content from the recording medium 24 is stopped.

  An example of a playback screen is shown in FIG. FIG. 8A is an image diagram of a program recorded on the recording medium 24, and shows a state in which a CM is inserted and recorded between the main program (Scene1, Scene2, and Scene3) and each main program. . FIG. 8B is an image diagram when the program shown in FIG. 8A is reproduced by the conventional CM skip reproduction. In this case, only the main program is reproduced, and no CM is reproduced. On the other hand, FIG. 8C is an image diagram when the program shown in FIG. 8A is reproduced by the CM skip reproduction described in the present embodiment.

  In the case of the present embodiment, the skipped CM is multiplexed with a part of the reproduced video of the main program after the skip and displayed in the small screen. The reproduction output of the audio corresponding to the small-screen CM displayed at this time can be selected from the combined output of the prohibition and the audio of the main screen. Then, when the viewer looks at the small screen CM displayed as shown in FIG. 8C and the viewer is interested in or interested in the viewer, the small screen CM is selected. In this case, as shown in FIG. 8D, the reproduction of the main program (Scene 3) is interrupted, the program returns to the position of the selected CM, and the normal reproduction is resumed from the beginning of the CM.

  As described above, in the present embodiment, the CM exposure effect is not reduced because the CMs are displayed in multiple on the small screen with respect to the skip operation for the designated time corresponding to the number of times the content is reproduced.

  FIG. 9 shows a flowchart of another multiple display operation of the embodiment shown in FIG. When the reproduction is started, the control device 18 first obtains reproduction information recorded in association with the content to be reproduced (S31). In the case of unreproduced content, the number of reproductions in the reproduction information is zero.

  Normally, since two images are not being displayed in a multiplexed manner (S32), a reproduction stop instruction (S35) or a CM skip instruction (S36) is awaited.

  When a ticket instruction is input from the operation unit 16 during reproduction and it is determined that the skip target is CM from CM content information in the reproduction information of the content (S36), the control device 18 acquires the reproduced information. The display size is determined from the information on the number of times of reproduction in accordance with the prior setting (S37). For example, as shown in FIG. 10, when the number of playbacks is 0, the display size is set to 1/4 of the display screen, and when the number of playbacks is 1, the display size is set to 1 / When the display size is 8, the display size is 1/16 of the display screen size, and when the display count is 3 times or more, the CM content is not displayed, that is, the multiple display is not performed. And set. Of course, the number of reproductions and the display size may be associated with each other in a different relationship. The control device 18 determines the display size in the multiplex display of the CM content from the display size setting information and the number of reproductions.

  The control device 18 instructs the recording / playback processing device 22 and the video processing device 26 to perform multiplex display of the CM content to be skipped according to the determined display size (S38). The recording / playback processing unit device 22 simultaneously outputs the playback video (video 1) of the content after skipping and the playback video (video 2) of the CM content targeted for skipping to the video processing device 26. Generates a video signal obtained by overlaying video 1 (content 1) with video 2 (content 2) having a specified display size, and supplies the video signal to the display device 28. As a result, the CM content is multiplexed and displayed on the original content with a display size corresponding to the number of times of reproduction.

  When the multiple display has elapsed for a predetermined time (S33), the control device 18 instructs the recording / playback processing device 22 and the video processing device 26 to stop the multiple display (S34). In response to this instruction, the recording / playback processing device 22 stops the output of the video 2, and the video processing device 26 applies only the video signal of the video 1 of the recording / playback processing device 22 to the display device 28.

  During the above processing, when the user gives an instruction to stop playback through the operation unit 16 (S35), the control device 18 instructs the recording / playback processing device 22 to stop playback of the corresponding content, and the recording / playback processing device 22 Reading of the recording information of the corresponding content from the recording medium 24 is stopped.

  According to the present embodiment, since the CM content to be skipped is displayed in a display size corresponding to the number of times of playback, viewing of the CM can be ensured.

  In the operation flow shown in FIG. 9 as well, a function for reproducing CM content from the beginning on a full screen may be added in response to a reproduction instruction for CM content on a small screen as in the operation flow shown in FIG.
