  The hibernation state means that the storage contents of the semiconductor memory of the storage unit 120 are saved to the hard disk of the storage unit 120 as they are, the external storage device of the storage unit 120 such as a hard disk drive, the input unit 130, the output unit 140, the communication unit 150, The tuner unit 160 and a part of the power source of the control unit 110 are turned off.

When it is determined that T is immediately after T ₅ has elapsed (when YES is determined in step S155), in step S156, the control unit 110 executes control for shifting to a dormant state. Here, the state is shifted to the hibernation state, but may be shifted to the power-off state of the data processing apparatus 100 by the shutdown.

If it is determined that T is not immediately after T ₅ (NO in step S155), and after step S156, control unit 110 returns the process to be performed to the process of step S102.

That is, the processing from step S141 to step S156, for a predetermined setting period T ₁ through T _5, on condition that there is no manipulation of the data processing apparatus 100 from the user, respectively, the process relates to power saving is executed.

As described above, according to the data processing apparatus 100 of the second embodiment, as shown in step S111, the control unit 110 performs processing other than the power saving processing program as processing of processing data. The video data is processed. As shown in step S111, the type of data processing in the control unit 110 is determined. Step S132, step S141, step S143, step S151, the step S153, as shown at steps S155, during the set period T ₁ through T ₅ which is set in advance, the signal from the outside, such as a keyboard 131 or remote control 132 It is determined that there is no input.

Step S142, step S144, step S152, step S154, as shown at steps S156, the control unit 110, during the set period T ₁ through T _5, on condition that it is determined that there is no input signal, As processing related to power saving, control for turning off the power of a display device such as a screen saver and a television receiver 141, control for turning off the power of an external storage device such as a hard disk drive, control for shifting to a standby state, and pause Control to shift to the state is executed. As shown in steps S111 and S115, the control unit 110 prohibits execution of processing related to power saving by turning off the power saving function according to the determined type of data processing.

  In this way, it is possible to provide the data processing apparatus 100 that can dynamically execute the power saving process according to the type of data processing.

Also, as shown in step S111 and step S115, when the control unit 110 determines that the determined data processing type is video data processing as continuous data processing, the power saving function is activated. By being turned off, it is not determined that the power saving function is turned on in step S131, and the no-operation time T is not reset in step S133. Therefore, in steps S141, S143, S151, S153, and S155, respectively. It is not determined that the no-operation time T is immediately after the set periods T _{1 to} T ₅ have elapsed, and the processes of Step S142, Step S144, Step S152, Step S154, and Step S156 are not executed. Execution is prohibited.

  As described above, it is possible to prevent the power saving process from being executed when the video data processing is being executed as continuous data processing, which is particularly inconvenient when the power saving processing is executed midway. it can.

  Further, as shown in steps S111 to S115 and steps S121 and S122, the control unit 110 calculates the end time of the moving image, and the power saving function is turned off until the calculated end time. Therefore, execution of the power saving process is prohibited until the reproduction process of the moving image data as the continuous data process is completed.

  In this way, it is possible to prevent the processing related to power saving from being executed until the processing of moving image data, which is continuous data processing, is completed, and after the continuous data processing is completed, execution of processing related to power saving is prevented. It is possible.

  Furthermore, as shown in step S113, the control unit 110 detects the playback time of the moving image indicated by the moving image data as specific information that can specify the time point at which the data processing ends. Then, as shown in step S114, step S115, step S121, and step S122, the control unit 110 executes the process related to power saving until the end time of playback of the moving image specified by the playback time that is the detected specific information. Is prohibited.

  In this way, it is possible to prevent the power saving process from being executed until the end of the data processing, that is, until the video playback end time, and after the continuous data processing ends, Execution is possible.

  Continuous data processing is processing of moving image data. The control unit 110 and the output unit 140 control the television receiver 141 that displays an image. As shown in step S <b> 111, the moving image data is reproduced and output to the television receiver 141 by the control unit 110. As shown in step S142, step S144, step S152, step S154, and step S156, the control unit 110 executes processing related to power saving control of the television receiver 141 by the control unit 110 and the output unit 140 as processing related to power saving. The

  As described above, when the process related to the power saving control of the television receiver 141 is executed in the middle, the process related to the power saving control of the television receiver 141 is executed when the reproduction output process of continuous moving image data is being executed. Can be prevented from being executed.

Further, as shown in step S142, one of the processing relating to the power saving which is executed by the control unit 110, the television receiver by the control unit 110 and the output unit 140 after a set period T ₁ from the process is started 141 is a process of executing a screen saver for notifying that 141 is controlled to a power saving state.

  As described above, it is possible to prevent the screen saver from being executed when the continuous moving image data reproduction / output process is being executed, which is particularly inconvenient if the screen saver is executed halfway.

  As shown in step S144, one of the processes related to power saving executed by the control unit 110 is a process of controlling the television receiver 141 to the power saving state by the control unit 110 and the output unit 140.

  As described above, when the television receiver 141 is controlled to be in the power saving state in the middle, the process of controlling the television receiver 141 to the power saving state when the continuous moving image data reproduction / output process is being executed is particularly inconvenient. Can be prevented from being executed.

In the third embodiment, in addition to the processes in steps S121 and S122, which are the processes between steps S115 and S131 of the second embodiment, steps S161 to S165 and step S171 are performed. The processing from step S178 to step S178 is executed. For this reason, processes other than step S121 and step S122 are the same as the processes described in FIG. 4, and therefore, a duplicate description will not be repeated.

  FIG. 5 is a flowchart showing a part of a power saving processing program executed by the data processing apparatus 100 according to the third embodiment. Referring to FIG. 5, when it is determined that the reproduction of the moving image has not started (when NO is determined in step S111), and after step S115, control unit 110 performs the process to be executed in step S161. Proceed to

  Next, in step S161, when the reproduction of the moving image is started, the control unit 110 determines whether or not the moving image is reproduction from the search result of the moving image. Specifically, the control unit 110 determines whether or not the reproduction of the moving image is started by selecting one file from the list of files with the extension of the moving image of the search result obtained by executing the file search program. .

  When it is determined that the playback is based on the video search result (when YES is determined in step S161), in step S162, the control unit 110 determines whether the search result includes a plurality of video files. To do. Specifically, the control unit 110 determines whether or not a plurality of moving image files are included in the list of files with extensions of moving images as a search result obtained by executing the file search program.

  When it is determined that a plurality of moving image files are included in the moving image search result (when YES is determined in step S162), in step S163, the control unit 100 turns on the search reproduction flag.

  The search / play flag is turned on when one of the searched video files is selected and the selected video is being played when the search results of the file search program include multiple video files. Flag that is turned on and turned off otherwise.

  In step S164, when the reproduction of the moving image is started, the control unit 110 determines whether or not at least a part of the performers of the moving image are included in the performers of the previously viewed moving image.

  Here, a performer refers to an actor, dancer, performer, singer, other performer, and person who conducts or directs the performance. A performance is a performance of a work that plays theatrically, dances, performs, sings, speaks, rejoices, or performs in other ways. Including those having. A copyrighted work is a creative expression of thought or feeling, and belongs to the range of literary, academic, art or music.

  When it is determined that at least a part of the performers of the current video is included in the performers of the previous video (when determined YES in step S164), in step S165, the control unit 110 sets the related video viewing tendency value. Add one. The related video viewing tendency value is a value indicating a tendency to view continuously related videos (videos of the same performer in the present embodiment), and whenever a related video is viewed continuously, One is added. That is, it is shown that the higher the related video viewing tendency value, the stronger the tendency to continuously watch related videos.

  When it is determined that at least a part of the performers of this video is not included in the previous performers (when NO is determined in step S164), and after step S165, in step S121, the control unit 110 As in step S121 in FIG. 4, it is determined whether or not the playback end time of the moving image stored in step S114 has come. When it is determined that the end time has come (when YES is determined in step S121), in step S171, the control unit 110 determines whether or not the genre of the reproduced moving image is a movie. Specifically, information indicating the genre is included in the moving image data, and the genre of the moving image is determined by referring to the information indicating the genre.

  If it is determined that the genre of the movie is a movie (YES in step S171), control unit 110 advances the process to be executed to step S184 described later. On the other hand, when it is determined that the genre of the moving image is not a movie (when NO is determined in step S171), in step S172, the control unit 110 determines whether the genre of the moving image is drama.

  When it is determined that the genre of the moving image is a drama (YES in step S172), control unit 110 advances the process to be executed to step S176 described later. On the other hand, when it is determined that the genre of the moving image is not a drama (when NO is determined in step S172), in step S173, the control unit 110 determines whether or not the search / playback flag described in step S163 is ON. .

  If it is determined that the search / playback flag is on (YES in step S173), in step S174, control unit 110 turns off the search / playback flag and executes the processing to be executed in step S176 described later. Proceed.

  On the other hand, when it is determined that the search / playback flag is not on (when NO is determined in step S173), in step S175, the control unit 110 determines whether the related video viewing tendency value is equal to or greater than a predetermined value (here, 100). Judge whether or not. In the present embodiment, it is determined whether or not there is a tendency to view a related video depending on whether or not the related video viewing tendency value is a predetermined value or more. The predetermined value that is the threshold value is not limited to 100, and may be another value.

  When it is determined that the related video viewing tendency value is equal to or greater than the predetermined value (when YES is determined in step S175), control unit 110 advances the process to be performed to the process of step S176 described later. On the other hand, when it is determined that the related video viewing tendency value is less than the predetermined value (NO in step S175), control unit 110 advances the process to be performed to the process of step S182 described later.

  In step S176, control unit 110 turns on the reservation flag and returns the process to be executed to the process in step S102. Even if it is determined that it is the end time of the playback of the video, the reservation flag is omitted if a specific condition is determined such that it is determined that the user is likely to continue watching the video. A flag indicating that the power function is reserved, and is turned on when the power function is reserved, and is turned off when the power function is not reserved.

  In the present embodiment, as specific conditions, there are a condition that the genre of the reproduced video is drama, a condition that the moving image is reproduced from the search result, and a condition that a tendency to view related videos is strong. When it is satisfied, that is, when it is determined that the user is highly likely to continue to watch the moving image, turning on the power saving function is reserved.

  As a result, when there is a high possibility that the user will continue to watch the video, the power saving function will not be turned on immediately, so when the user is searching for, searching for, or searching for the next video to watch It is possible to prevent the processing related to power saving from being executed.

  On the other hand, if it is determined that the playback end time of the moving image stored in step S114 is not reached (NO in step S121), in step S181, control unit 110 determines whether the reservation flag is on. Determine whether. If it is determined that the reservation flag is not on (NO in step S181), control unit 110 advances the process to be performed to the process in step S131 described with reference to FIG.

  On the other hand, when it is determined that the reservation flag is on (when YES is determined at step S181), and at step S172, step S173, and step S175, it is determined that the possibility that the user continues to watch the moving image is not high. In step S182, the control unit 110 determines whether the moving image player is playing a moving image.

  If the video player determines that the video is not being played back (if NO is determined in step S182), in step S183, the control unit 110 checks the communication unit 150 to check the Internet 300 and the video service server 200. It is determined whether or not moving image stream data is being received via the communication unit 150.

  When the video player determines that the video is being played back (when YES is determined in step S182), and when it is determined that the video stream data is being received (when YES is determined in step S183). Regardless of whether or not it is determined that it is the playback end time of the moving image in step S121, it is almost certain that the moving image is being played back, so control unit 110 turns on the power saving function in step S122. The process to be executed proceeds to the process of step S131 described with reference to FIG.

  On the other hand, if it is determined that the stream data of the moving image is not being received (NO in step S183), it is determined in step S182 that the moving image playback player is not reproducing the moving image. Regardless of whether or not the end time is determined, it is almost certain that the movie is not being played back. Therefore, in step S184, the control unit 110 turns off the reservation flag, and in step S122, the step of FIG. As in step S122, the power saving function is turned on, and the process to be executed proceeds to the process in step S131 described with reference to FIG.

  Also, if it is determined in step S121 that it is the playback end time of the movie, and if the genre of the movie that was being played is determined to be a movie in step S171, the reservation flag is turned off in step S184. In step S122, the power saving function is turned on.
