  The control unit 100 activates a system control program and various processing programs recorded in advance in the storage unit 107 in response to an operation command from the remote controller 200 via the reception unit 102. In the present embodiment, an image reproduction time control program is executed. The image playback time control program executed by the control unit 100 includes a content supply unit 103, a playback control unit 104, and a decoding unit 105 as functional blocks. The function of each functional block will be described later.

  The surrounding environment supply unit 101 notifies the reproduction control unit 104 of the detected surrounding environment information based on the surrounding environment information acquisition command received from the reproduction control unit 104. In this embodiment, it is assumed that the surrounding environment information supply unit 101 includes a microphone 108, a camera 109, a GPS (Global Positioning System) receiver 110, an odor sensor 111, and a temperature sensor 112. It is assumed that temperature sensor 112 is housed in the housing of remote controller 200 because it is affected by heat generated from electronic components and the like built in the housing in television broadcast receiving apparatus 10. Examples of the surrounding environment information include voice level information, person recognition information, position information, temperature information, and odor information. These pieces of surrounding environment information may be used alone or in combination.

  The receiving unit 102 notifies the playback control unit 104 of a playback content selection result and a content playback / stop request based on the user's operation of the remote control 200 as operation commands. In this embodiment, the operation command is received from the remote controller 200. However, the present invention is not limited to this. Other devices may be used, and the operation command may be recognized by voice recognition or character recognition.

  Based on the content identification information acquisition command received from the playback control unit 104, the content supply unit 103 reads the content identification information 310 of the content 300 from the storage unit 107 and notifies the playback control unit 104. In the present embodiment, the content 300 is stored in the storage unit 107. However, the content 300 may be read from a storage medium that is detachable from the television broadcast receiving apparatus 10, or may be received from the network. You may do that.

  The playback control unit 104 controls data to be played back to the playback unit 106 in response to an operation command from the receiving unit 102. Operations for other functional blocks performed after the reproduction control unit 104 receives an operation command from the reception unit 102 will be described.

  First, the playback control unit 104 sends a content identification information acquisition command to the content supply unit 103 in response to an operation command from the reception unit 102, and receives content identification information from the content supply unit 103.

  Also, the playback control unit 104 sends a peripheral environment information acquisition command to the peripheral environment information supply unit 101 in response to an operation command from the reception unit 102, and the peripheral environment information supply unit 101 transmits the peripheral of the television broadcast receiving apparatus 10. Receive environmental information. Furthermore, the reproduction control unit 104 stores a reference value used for determining the received surrounding environment information.

  Also, the playback control unit 104 sends a playback data information acquisition command to the decoding unit 105 in response to the operation command from the receiving unit 102, and receives the data number being played back by the decoding unit 105 as playback data information. In addition, the reproduction control unit 104 sends a reproduction data control command instructing to start and stop reproduction of data output to the reproduction unit 106 to control the reproduction operation. Further, the reproduction control unit 104 has a time measuring function, and determines the generation and notification timing of a reproduction data control command.

  The decoding unit 105 generates a reproduction data acquisition command from the reproduction data control command received from the reproduction control unit 104. This reproduction data acquisition command is notified to the content supply unit 103, and the content data 320 of the content 300 is read from the storage unit 107. The decoding unit 105 reproduces the content data 320 and notifies the reproduction control unit 104 of the data number of the content data 320 being reproduced as reproduction data information after reproducing the data for a certain period of time. Data reproduction start and reproduction stop are performed based on a reproduction data control command received from the reproduction control unit 104.

  The playback unit 106 plays back the playback data output from the decoding unit 105. For example, an LCD (Liquid Crystal Display) provided in the television broadcast receiver 10 is used. A plasma panel, a projector, or a cathode ray tube (CRT) may be used as the reproducing unit 106. In this embodiment, the reproduction data format is RGB, but the reproduction data format may be other data formats such as YUV.

  The storage unit 107 is a storage medium that stores the content 300. FIG. 3 is an example of a conceptual diagram of the storage state of the content 300 in the present embodiment. The content 300 includes content identification information 310 and content data 320. The content identification information 310 includes a content number 311, a group number 312, a data number 313, and content detailed information 314.

  The content number 311 is a number uniquely assigned to the content 300. The group number 312 is a number assigned to single or plural data. The grouping is performed for each scene of data constituting the content, for example. The data number 313 indicates the total number of data constituting the content 300. The detailed content information 314 includes person information recorded in each data constituting the content 300, data creation location, data creation time, data color information, and information indicating data keywords. The keyword related to data is a keyword related to data such as during a meal or a trip, and can be set by the user.

  The content data 320 is assumed to be composed of a single data or a plurality of data, and is assumed to be composed of a plurality of data 3211 to 2232 in the present embodiment. Further, when there are a plurality of data, it is assumed that the data is grouped, and in the present embodiment, a plurality of data 3211 to 232 is grouped into a plurality of groups 321 to 323. That is, the data 3211 to 3212 are grouped as a group 321, the data 3221 to 3223 are grouped as a group 322, and the data 3231 to 2232 are grouped as a group 323.

  In this embodiment, a still image has been described as an example of data to be reproduced. However, a moving image, character data, audio data, or the like may be used. In the case where the data is composed of a single data instead of a plurality of data, the same effect as that of the present embodiment can be obtained by dividing the single data.

  Next, the surrounding environment information detected by the surrounding environment information supply unit 101 and the reproduction control based on the detected surrounding environment information will be described. In the present embodiment, the surrounding environment information includes voice level information, person recognition information, position information, temperature information, odor information, and temperature information.

  The sound level information is surrounding sound information detected from the microphone 108. By judging the reaction of the viewer based on the sound, a case where the sound level is equal to or higher than the threshold value can be set as an image having a large reaction, and the reproduction time can be set long. In other words, an image that attracts the viewer's interest can be viewed longer than other images, and the viewer can follow the preferences without having to perform operations such as rewinding and pausing to reproduce the image. Viewing is realized.

  The person recognition information is identification information of a person who is watching, which is determined from an image captured by the camera 109. The identification information of the viewing person is information indicating a result of determining the person based on the similarity of the face area by detecting the face area from the image in front of the television broadcast receiving apparatus 10 photographed by the camera 109. The similarity of the face area is determined by the arrangement of eyes, nose, mouth and the like, for example. By comparing the identification information of the viewing person and the person information included in the detailed content information 314, it is possible to compare the person being viewed and the person shown in the image. That is, it is possible to extend the reproduction time of an image in which the person being viewed is captured, and to view an image in which the person being viewed is viewed longer than other images.

  The position information is information indicating the installation position received from the GPS receiver 110. By comparing this position information with information indicating the data creation location included in the detailed content information 314, the installation position of the television broadcast receiving apparatus 10 and the creation position of the image data can be compared. Therefore, by setting the reproduction time of the image data created at a place close to the position where the image is viewed to be long, it is possible to view with an emphasis on the image related to the place where the image is viewed.

  The temperature information is information obtained by detecting the temperature during viewing from the temperature sensor 112 provided in the remote controller 200. By comparing the temperature information with the creation time of the data included in the content detailed information 314, image data suitable for the temperature being viewed can be reproduced. For example, when the detected temperature is high, an image whose data creation time is from spring to summer is played back for a long time, and when the temperature is low, an image whose data creation time is from autumn to winter is played back for a long time.

  Further, by comparing the temperature information with the color information of the data included in the detailed content information 314, data suitable for the temperature being viewed can be reproduced. For example, when the detected temperature is high, data recorded with a lot of cool colors can be reproduced for a long time, and when the temperature is low, data recorded with a lot of warm colors can be reproduced for a long time. Data that includes a cool color that gives a cool impression in a warm climate can be viewed for a long time, while data that contains a warm color that gives a warm impression in a cold climate can be viewed for a long time.

  The odor information is information related to the odor around the television broadcast receiving apparatus 10 detected from the odor sensor 111. By comparing this odor information with information indicating a keyword related to data, data suitable for the situation being viewed can be reproduced. For example, when an odor equal to or greater than the threshold stored in the reproduction control unit 104 is detected, it is determined that the meal is being eaten, and the reproduction time of data including the keyword “meal” in the information indicating the keyword related to data may be shortened. it can.

  In the above description, the reproduction time of data determined to be desirably reproduced by referring to the surrounding environment information and the detailed content information 314 is increased, but the present invention is not limited to this. That is, only data that is determined to be desirable to be reproduced may be reproduced. In addition, the user can change the playback time and whether or not to play based on the surrounding environment information.

  Control is performed on data to be reproduced by associating the surrounding environment information during data reproduction configured as described above with the data being reproduced. That is, by referring to the surrounding environment information received from the surrounding environment information supply unit 101 and the reproduction data information received from the decoding unit 105, the reproduction time of the content data 320 is changed, so that data in accordance with the surrounding environment is obtained. Perform playback.

  Next, the operation of the reproduction control unit 104 when performing reproduction data control will be described. FIG. 4 is a flowchart showing a reproduction data control procedure executed by the reproduction control unit 104 according to the present embodiment. In the following control procedure, sound level information will be described as an example of ambient environment information.

  First, the reproduction control unit 104 determines whether or not an operation command has been received from the reception unit 102 (step S101). As a result of the determination in step S101, when it is determined that no operation command has been received (No in step S101), the process returns to step S101.

  On the other hand, if it is determined that an operation command has been received (Yes in step S101), the playback control unit 104 determines whether there is content specified from the operation command (step S102). If it is determined in step S102 that the specified content does not exist (No in step S102), this procedure ends.

  On the other hand, if it is determined that the designated content exists (Yes in step S102), the reproduction position is initialized (step S103). The initialization of the reproduction position is to set the reproduction position as group 0000.

  Next, the playback control unit 104 sends a playback data control command to the decoding unit 105, and starts outputting playback data to the playback unit 106 (step S104). That is, the decoding unit 105 reads out the content data 320 instructed to be reproduced by the received reproduction data control command from the storage unit 107, converts the content data 320 into a format that can be reproduced by the reproduction unit 106, and outputs it to the reproduction unit 106. The reproduction starts from the data 0001 of the group 0001 of the designated content 300.

  Next, the reproduction control unit 104 determines whether or not a certain time has elapsed (step S105). As a result, when it is determined that it has not been determined that the fixed time has passed (No in step S105), step S105 is repeated until it is determined that the fixed time has passed. On the other hand, when it is determined that a certain time has elapsed (Yes in step S105), the reproduction control unit 104 receives reproduction data information from the decoding unit 105 (step S106).

  Next, the reproduction control unit 104 receives the surrounding environment information from the surrounding environment information supply unit 101 (step S107). That is, the reproduction control unit 104 sends a surrounding environment information acquisition command to the surrounding environment information supply unit 101 and receives the surrounding environment information.

  Next, it is determined from the reproduction data information received in S106 whether the reproduction data is in the same group as the currently reproduced data (step S108). If it is determined in step S108 that the reproduction data is not in the same group (No in step S108), the process proceeds to step S111 described later. If playback is started and the first data 0001 of the content is being played back, the playback position is initialized in step S103, that is, the playback position is set to group 0000. Proceed to S111.

  The reproduction control unit 104 stores the value detected by the surrounding environment information supply unit 101 as a reference value in the reproduction control unit 104 (step S111). That is, the detected value of the data reproduced first in the group is set as the reference value.

  On the other hand, if it is determined in step S108 that the reproduction data is the same group (Yes in step S108), it is determined whether or not the detected value is larger than the reference value stored in step S111 (step S109). That is, in the case of data within the same group, the detected values are compared.

  As a result of the determination in step S109, if it is determined that the detected value is larger than the reference value (Yes in step S109), the reproduction time of the data being reproduced is extended (step S110). That is, when a reaction larger than that of the previously reproduced image is obtained, it is determined that the image attracts the viewer's interest and is reproduced for a long time.

  On the other hand, if it is determined in step S109 that the detected value is equal to or less than the reference value (No in step S109), the process proceeds to step S111. That is, when a reaction larger than that of the previous image is not obtained, the normal reproduction time is maintained and the detection value is set as a reference value.

  Next, the reproduction control unit 104 holds the data number of the reproduction data information received in step S106 (step S112). Next, the playback control unit 104 determines whether or not the playback data is the last data of the content 300 (step S113). That is, it is determined whether or not the data number held in step S112 is equal to the number of data 313 in the content identification information 310 received in step S102.

  As a result of the determination in step S113, if it is determined that there is no last data of the content 300 (No in step S113), the reproduction control unit 104 increments the data number (step S114). That is, a number obtained by adding 1 to the reproduced data number is set as the data number. Then, the procedure from step S104 described above is repeated. That is, the data set next to the data being reproduced is set as reproduction data and output to the reproduction unit 106.

  On the other hand, as a result of the determination in step S113, when it is determined that the reproduction data is the last data of the content 300 (Yes in step S113), the reproduction control unit 104 stops outputting the reproduction data (step S115). That is, the playback control unit 104 sends a playback data control command indicating playback stop to the decoding unit 105, and stops playback of data. Thus, the reproduction data control procedure executed by the reproduction control unit 104 is completed.

  As described above, according to the present embodiment, the reproduction time of the data being reproduced can be extended in accordance with the surrounding reaction when this data is displayed. Viewing of the selected image is realized.

  In the present embodiment, the television broadcast receiving apparatus 10 has been described as an example of the information processing apparatus, but the present invention is not limited to this and can be applied to various apparatuses. For example, when applied to a personal computer, vibration information may be included as the surrounding environment information. The vibration information is information related to the movement of the device detected from an acceleration sensor or the like. For example, if it is detected from the vibration information that the device is periodically moving finely, that is, it is detected that the device is vibrating, the viewer is expected to be moving with the device. Therefore, the playback time of each image constituting the content 300 is set longer than usual. Alternatively, by applying an effect such as sandwiching a single color screen between image transitions, it becomes easier to view the image even during movement.

  Note that the present invention is not limited to the above-described embodiment as it is, and can be embodied by modifying the constituent elements without departing from the scope of the invention in the implementation stage. In addition, various inventions can be formed by appropriately combining a plurality of components disclosed in the embodiment. For example, you may delete some components from all the components shown by embodiment. Furthermore, constituent elements over different embodiments may be appropriately combined.
