Next, based on the information stored in the reproduction history acquisition process, a file list in which priorities are assigned to the contents for the connected video / audio viewing device 53 is displayed.
FIG. 3 is a flowchart showing a process for assigning priorities for file selection.
First, when viewing by connecting to a specific image / audio viewing device 53, the microcomputer 25 connects to the image / audio viewing device 53 via the communication means 52 (step S1), and the image / audio viewing device connected in step S1. 53 individual identification information is acquired by the communication means 52 (step S2).

  Then, it is determined whether or not there is a connection history (step S3). When there is a connection history in step S3, the microcomputer 25 reproduces information on the reproduction history of the connected image / audio viewing device 53 that matches the individual identification information. Is read from the nonvolatile memory 50, and statistical information for assigning priorities is calculated from the connection information and the reproduction file information obtained from the reproduction history.

The following is an example of statistical information for assigning priorities.
After the next connection, when connecting to a specific image / audio viewing device 53 and viewing images and sounds, the microcomputer 25 connects the image / audio viewing device of the connection partner that matches the individual identification information of the connected image / audio viewing device 53. The connection information and playback file information of 53 playback histories are read from the nonvolatile memory 50 for all cases (step S4), and information obtained from the playback history is calculated.

Information obtained from this reproduction history includes statistical items such as the date, number of times, frequency, and accumulated time of transmission of a specific image / audio source signal transmitted to a specific image / audio viewing device 53. .
The microcomputer 25 gives priority to the file indicating the content based on the statistical information.

  Priorities can be assigned in order of date and time from the most recent, method of prioritizing in descending order of the number of times viewed, method of prioritizing in descending order of frequency within a certain period, viewing A priority setting concept and method, such as a method of assigning priorities in descending order of time accumulation, can be considered. Alternatively, a new priority may be created by combining these priorities.

  Here, first, the microcomputer 25 rearranges the files in the order of the number of reproductions (step S5), and then rearranges the files having the same number of reproductions (substantially the same number) in the order of the reproduction frequency in step S5. (Step S6). In step S6, the microcomputer 25 rearranges the files having the same reproduction frequency (substantially the same number) in the order of reproduction accumulation time (step S7).

  Further, in step S7, the microcomputer 25 rearranges the files having the same cumulative reproduction time (almost the same number) in the order of the reproduction date and time (step S8). As a result, a file list in which priorities are set is created.

  Note that the priority of which statistical item is given priority can be switched by changing the order of the file rearrangement process indicating the contents in the file list in which the priority order shown in steps S5 to S8 is set.

  Furthermore, if there is no reproduction history for the target image / audio viewing apparatus in step S3, the microcomputer 25 reads all file information items (step S10) and rearranges them in the order of reproduction date and time (step S11). A file list with priorities set is created.

Then, the microcomputer 25 displays the priority order playlist (step S9).
The microcomputer 25 displays the priority order file list in step S9 on the image display unit 17 or the connected image / audio viewing device 53 with the GUI function.

  By this processing, the microcomputer outputs the information reproduced and transmitted to the connection partner's video / audio viewing apparatus with the priority order of the transmitted images and sounds, so that the information can be displayed as a priority file list.

A display example of the above-mentioned priority order file list is shown in FIG.
In FIG. 4, in this list, the file name 71, the recording date / time 72, the recording time 73, and the file size 74 of the files arranged in the priority order are displayed with different colors or high-intensity highlights. Alternatively, a display designated by scrolling with an arrow or the like is also possible. This is selected by moving up, down, left and right by the user interface 26.

With the above operation, it becomes possible to efficiently select content highly relevant to people who view with the video / audio viewing device as the connection partner, that is, people who have a common preference.
As a result, the user can easily reproduce images and sounds enjoyed in the past by selecting a file from the priority order file list. This is also effective in the case where the same image and sound are viewed on the same image and sound viewing apparatus with different dates and times, with different friends and acquaintances.

  According to the above-described embodiment, the stored list for each image / audio viewing device is displayed on the LCD panel of the main body even when the image / audio viewing device is not connected to the main body via a switch or GUI user interface. It can be viewed on an image display device or a connected external image display device.

  The priority obtained from this statistical information is also a guide for selection when copying and distributing content files viewed by relatives, friends, etc. who viewed images and audio together to some recording media through an external stream interface. Useful.

In this case, it is considered preferable to raise the priority of the file that is the most frequent in the target period. FIG. 5 shows a flowchart for determining the priority order in this case.
FIG. 5 is a flowchart showing a process for assigning priorities for selecting other files.
First, when viewing by connecting to a specific video / audio viewing device 53, the microcomputer 25 connects to the video / audio viewing device 53 via the communication means 52 (step S21), and the video / audio viewing device connected in step S21. 53 individual identification information is acquired by the communication means 52 (step S22).

  Then, it is determined whether or not there is a connection history (step S23), and if there is a connection history in step S23, the microcomputer 25 reproduces information on the reproduction history of the connected video / audio viewing device 53 that matches the individual identification information. Is read from the nonvolatile memory 50, and statistical information for assigning priorities is calculated from the connection information and the reproduction file information obtained from the reproduction history.

  After the next connection, when connecting to a specific image / audio viewing device 53 to view images and sounds, the microcomputer 25 connects to the connected image / audio viewing device that matches the individual identification information of the connected image / audio viewing device 53. The connection information and reproduction file information of 53 reproduction histories are read from the nonvolatile memory 50 for all cases (step S24), and information obtained from the reproduction history is calculated.

  Here, first, the microcomputer 25 rearranges the files in the order of the reproduction frequency (step S25), and then rearranges the files having the same rank (substantially the same number) in the reproduction frequency in the step S25. (Step S26). In step S26, the microcomputer 25 rearranges files having the same number of reproductions (substantially the same number) in the order of reproduction accumulation time (step S27).

  Further, in step S27, the microcomputer 25 rearranges the files having the same cumulative reproduction time (almost the same number) in the order of reproduction date and time (step S28). As a result, a file list in which priorities are set is created.

  It should be noted that the priority of which statistical item is prioritized can be switched by changing the order of the file rearrangement process indicating the contents in the file list in which the priority order shown in steps S25 to S28 is set.

Further, if there is no reproduction history for the target audio / video viewing apparatus in step S23, the microcomputer 25 reads all file information items (step S30) and rearranges them in the order of reproduction date and time (step S31). A file list with priorities set is created.
Then, the microcomputer 25 displays the priority order playlist (step S29).
