  Note that the number of information reproducing apparatuses connected to the server is not limited to two, and an embodiment in which more information reproducing apparatuses are connected to the server and the above-described download process is performed may be used.

  In addition, when the information reproducing apparatus A10a reproduces the corresponding content based on the downloaded reproduction procedure list, the information reproducing apparatus A10a performs a procedure different from the reproduction procedure described in the reproduction procedure list by the operation unit 31 or the remote controller RC. Special playback such as skip playback and double speed playback of the content is performed (S302), and a new playback procedure list describing the playback procedure performed is generated (S303). It should be noted that special playback procedures such as skip playback and double speed playback are described in the downloaded playback procedure list, and a new playback procedure list is not generated when content is played back based on these procedures.

  Further, when the information playback apparatus A10a starts uploading the newly generated playback procedure list (S304), the upload execution information is provided to the data management unit 101 (S335), and the data management unit 101 stores the provided upload execution information. Provided to the list server 110 and the content server 111. Then, each server performs a process of associating the uploaded list with the content based on the provided information (S343), and the information reproducing apparatus A10a lists the generated reproduction procedure list via the data management unit 101. Upload to the server 110 (S336).

  Then, when the information reproduction apparatus B10b starts downloading the reproduction procedure list corresponding to the content stored (S312), download execution information is provided to the data management unit 101 (S337), and the data management unit 101 provides the download execution provided. Based on the information, the corresponding playback procedure list is requested to the list server 110. The list server 110 provides the requested list to the data management unit 101 (S344), and the data management unit 101 provides the information reproduction device B10b with a list requested by the information reproduction device B10b from the provided reproduction procedure list. For downloading (S338).

  Further, the information reproducing apparatus B10b reproduces the corresponding content based on the newly downloaded reproduction procedure list (S313). For example, if the downloaded reproduction procedure list is a list in which the reproduction procedure performed by the information reproduction apparatus A10a is described, the information reproduction apparatus B10b reproduces content or special reproduction based on the reproduction procedure performed by the information reproduction apparatus A10a. .

  It should be noted that downloading of content data by the information reproducing apparatus B10b may be an embodiment that is performed after the upload, not an embodiment that is performed before the upload of the reproduction procedure list by the information reproducing apparatus A10a.

  That is, when a plurality of information playback apparatuses of this embodiment are connected to a server, a playback procedure list of specific content generated by the specific information playback apparatus is uploaded to a server connected to the Internet and uploaded. The playback procedure list can be downloaded by different information playback devices.

  Also, uploading or downloading of the playback procedure list is not limited to a specific information playback device, but an embodiment in which all connected information playback devices can upload and download.

Also, the embodiment may be such that uploading or downloading of the playback procedure list is performed on a plurality of lists at once.
Next, an embodiment of content reproduction processing based on the reproduction procedure described in the reproduction procedure list will be described with reference to FIG.
FIG. 4 is a conceptual diagram showing a correspondence relationship between a reproduction procedure list for reproducing content according to the present embodiment and content data. Note that the content data in FIG. 4 is in a form encoded in MPEG.

  The video / audio data of the content encoded by the MPEG has a hierarchical structure, and a hierarchy called a GOP (Group Of Picture; hereinafter referred to as GOP) layer is below a higher hierarchy called a sequence layer. is there. One GOP includes video / audio data corresponding to about 15 frames in an MPEG composite image.

  In the DVD-VR format, which has a data structure encoded in MPEG and is a video recording format for an optical disc, a management information file is defined separately from the video / audio data file. The management information file stores management information for reproducing the video / audio data of the content. The management information is necessary for reproducing video / audio data such as a time map that describes the relationship between the content reproduction time and the position information of the video / audio data, and the data size and reproduction time per GOP. Information.

  That is, the playback procedure list in the present embodiment can be realized by using the time map reserve bit, but the description of the playback procedure list is not limited to the mode using the time map.

  First, FIG. 4A shows a correspondence relationship between a playback procedure list and content data in a case where sequential playback is performed without special playback such as skip playback or double speed playback. Each list describes position information of a corresponding GOP, a list number to be accessed next, and the like. Based on the position information described in the list, the corresponding GOP data is subjected to MPEG decoding processing and the like, and the description of the list to be accessed next is read. In other words, continuing the above processing means that the content data is sequentially reproduced based on the reproduction procedure list.

  Specifically, in FIG. 4A, in list 1, GOP1 is described as the corresponding GOP, and at the same time, the next access to list 2 is described. Similarly, list 2 describes GOP2 processing and access to list 3, and list n describes GOPn processing and access to list n + 1. Therefore, by sequentially reproducing the corresponding GOP described in each list, the content can be reproduced one time, that is, sequentially reproduced.

  On the other hand, FIG. 4B shows the correspondence between the playback procedure list and content data when special playback such as skip playback or double speed playback is performed. In the reproduction procedure, GOP1 is first processed by list 1 to access list 2 and processed, and then GOP2 is processed by list 2 to access list 3 and processed. At this time, in the list 3, the corresponding GOP is described as GOPn-2, the reproduction speed is 1 time, and the next list is described as the list n-1. Accordingly, GOP4 to GOPn-3 are skipped without being processed, and 1 × reproduction processing is performed from GOPn-2 to access list n-1. Further, the list n-1, the list n, and the list n + 1 are sequentially accessed and processed. In the list n + 1, the corresponding GOP is described as GOPn + 1, the reproduction speed is doubled, and the next list is described as the list n + 2. Therefore, GOPn + 1 is subjected to a double speed reproduction process and then accesses the list n + 2.

  That is, even when the target content data is the same as shown in FIGS. 4A and 4B, the corresponding GOP, playback speed, and next list are added to the playback procedure list using the time map in the DVD-VR format. By describing the number and the like, and sequentially processing the audio-video data based on the description, it is possible to perform not only sequential playback but also special playback such as skip playback and double speed playback.

  In the above description, the GOP is used in the MPEG-encoded signal as an access unit of content data in the reproduction procedure list. However, in the embodiment using time information, position information, and the like separated by a predetermined interval. There may be.

Next, processing for generating a playback procedure list in which procedures are described when special playback processing by the information playback apparatus of the present embodiment is performed will be described with reference to FIG.
FIG. 5 is a flowchart of the playback procedure list generation process by the information playback apparatus of this embodiment.
First, when the information reproducing apparatus starts content reproduction processing (S501), for example, processing for waiting for an operation input for special reproduction such as skip reproduction or double speed reproduction (S502) is performed, and there is no operation input (N in S502). Is not completed (N in S505), the process proceeds to a process of waiting for a special reproduction operation input (S502). However, if there is an operation input for special reproduction (Y in S502), the special reproduction processing with the operation input is performed (S503), and the contents of the special reproduction processing performed are stored in association with the position information of the content data. (S504). If the reproduction has not been completed (N in S505), the process proceeds to a process of waiting for a special reproduction operation input (S502).

  The contents stored each time the special reproduction process is executed are accumulated, that is, the contents of the special reproduction process associated with the position information of the content data are stored in time series.

  Then, a reproduction procedure list describing the special reproduction procedure stored in time series is generated (S506), and the generated reproduction procedure list is stored in the HDD 50 (S507).

Next, processing for reproducing content based on an arbitrary list selected from a plurality of downloaded reproduction procedure lists will be described with reference to FIG.
FIG. 6 is a flowchart of the content reproduction process based on the reproduction procedure list by the information reproduction apparatus of this embodiment.
First, when an arbitrary content is selected and an operation input for reproduction is made (S601), a plurality of reproduction procedure lists corresponding to the reproduction target content are presented from the plurality of downloaded reproduction procedure lists (S602). The reproduction procedure list is presented on a menu screen or the like on which an outline of the reproduction procedure, a reproduction time according to the reproduction procedure, and the like can be selected. Then, one list is selected from the presented lists (S603), and the target content is reproduced based on the selected list (S604).

  In addition, when there is only one playback procedure list downloaded for the playback target content, the content playback is started based on only one playback procedure without presenting the playback procedure list in a selectable manner. May be.

Next, a playback procedure list download process corresponding to an arbitrary content will be described with reference to FIG.
FIG. 7 is a flowchart of a playback procedure list download process corresponding to an arbitrary content by the information playback apparatus of the present embodiment.

Note that content selection is performed on a menu screen or the like on which thumbnails and titles of a plurality of contents are presented so as to be selectable. Then, the download control unit 201 uses the data management provided in the server 100 for information related to the selected content, for example, download execution information including content-related information such as ID and metadata uniquely assigned to the content. Provided to the unit 101 (S702). Further, the data management unit 101 requests the list server 110 for a plurality of corresponding playback procedure lists based on the provided content related information, and presents the plurality of lists provided from the list server 110 (S703). Then, a target list is selected from the presented multiple lists (S704), and is downloaded by the information reproducing apparatus (S705). The selection of the target list from a plurality of lists is performed on a menu screen or the like on which an overview of the reproduction procedure, a reproduction time according to the reproduction procedure, and the like are presented to be selectable.

  The content selection process corresponding to the playback procedure list to be downloaded that is performed at the beginning of the download process described above allows the data management unit 101 to select a plurality of contents based on the content data stored in the content server 111. An embodiment that presents thumbnails or the like may be used. In this case, information for selecting content is provided from the information reproducing apparatus, and the data management unit 101 performs processing for selecting the content based on the provided information, so that the content related information is not provided from the information reproducing apparatus.

  By the way, since a plurality of playback procedure lists corresponding to specific contents are stored in the list server 110, in the playback procedure list download process, all the corresponding playback procedure lists are presented and the user selects a list therefrom. It is very difficult. That is, it is desirable that the reproduction procedure list as download candidates has a limited quantity.

  For example, the data management unit 101 analyzes the tendency of the processing content described in the stored playback procedure list for each GOP that is a data access unit of the content by the playback procedure list, and includes a lot of trending processing content. That collects the evaluation of the playback procedure list from a plurality of information playback devices. A form of presenting a reproduction procedure list having a higher rank may be used.
