  As shown in FIG. 2, the recording / playback unit 251 of the recording / playback apparatus 100 creates a recording list in a list format as shown in FIG. 3 and presents it sequentially in order to present the content recorded in the storage device 111. (Step S11). Here, in the creation of the recording list, an unviewed / viewed flag of metadata is referred to for each content, and icons such as [NEW], [New], [Not], etc. This is referred to as a [NEW] icon, which may be an identification mark or an indicator instead of the icon. Next, when paired with the information communication terminal 700 through the wireless communication transmitting / receiving unit 113 (step S12) and receiving a content viewing request from the terminal 700 (step S13), the recording list is output to the terminal 700 (step S14). . When content in the recording list is designated from the terminal 700 (step S15), the designated content is read from the storage device 111 (step S16). Here, it is determined whether or not the designated content has not been viewed (step S17). If the designated content has not been viewed, if there is a reproduction instruction from the terminal 700 (step S18), reproduction of the designated content is started and streamed to the terminal 700. (Step S19).

  In this state, when there is a stop instruction from the terminal 700 (step S20), the reproduction of the content is stopped, and the stop position is saved as the resume position (step S21). At this time, the [NEW] icon added to the content played back on the terminal in the recording list is deleted (in the example of FIG. 3, women's golf open “BBBB”) (step S22). If there is an end instruction from the terminal 700 at this time (step S23), end processing such as pairing cancellation is performed (step S24), and the series of processing ends. If there is no end instruction, the process returns to step S13 to wait for a viewing request from the terminal 700.

  On the other hand, if the designated content is not viewed in step S17, a request is made to select whether to play from the beginning or from the beginning (display of the selection screen) (step S25). If selected (step S26), the process proceeds to step S18 to continue the process. If “Continue” is selected in step S26, when a continuation reproduction instruction is received (step S27), resume position information is acquired and reproduced from that position (step S28). Migrate and continue processing.

  As described above, in the recording / reproducing apparatus 100 of the present embodiment, the designated content is stream-distributed to the information communication terminal 700, and when the reproduction is stopped, the stopped position is held as resume position information on the main body side. The icon indicating “unviewed” is deleted. In this way, the stop position when played back on the main body side and the stop position when played back on the terminal 700 are centrally managed and shared as resume position information on the main body side, so that the terminal 700 plays back. When the resume position information is acquired from the main body side and reproduced on the terminal 700, the resume position information can be reproduced from that position. Further, even when playback is performed on the main body side of the recording / playback apparatus 100, it is possible to continue playback by taking over the resume position.

  Here, as shown in FIG. 3, even if the program is played back on the terminal 700 and is a normal recorded program that has not been played back on the main body of the recording / playback apparatus 100, [NEW] (or [New], Since the [unused] icon is deleted, it is possible to identify from the list that playback from the resume position stopped at the terminal 700 is possible when playback is performed on the main body side.

  As described above, according to the present embodiment, the recorded content can be played back not only when the recorded content is played back from the recording / playback apparatus main body but also from another device.

  In the above embodiment, an unviewed icon of [NEW] (or [New], [Not], etc.) is added to the recording list. If there is no unviewed icon, a playback check mark is added. You may do it.

  In the above embodiment, the recording list for selecting the recording content is targeted. However, the present invention can be similarly applied to a playlist.

  Moreover, although the case where one information communication terminal was pair-linked was described in the above embodiment, the present invention can be similarly implemented even when there are two or more. In this case, the resume position may be recorded for each terminal, and the resume position information corresponding to the pair link may be read.

  Note that the preview reproduction displayed when selecting the content to be reproduced does not have to be included in the reproduction.

  FIG. 4 is an example in which a plurality of information communication terminals (hereinafter referred to as “smartphones”) are paired, and the presence / absence of reproduction and the resume position information when reproduction is stopped are stored in the memory 211 for each smartphone. In FIG. 4, each piece of recorded content has a plurality of pieces of reproduction information. For example, here, the reproduction information 1 indicates reproduction information regarding the father's smartphone, the reproduction information 2 indicates reproduction information regarding the mother's smartphone, and the reproduction information 3 indicates reproduction information regarding the child's smartphone. Each piece of reproduction information includes smartphone identification information, reproduction presence / absence information, and resume position information. The smartphone identification information is identification information of each paired information communication terminal.

  FIG. 5 shows a state where the recording list is displayed on the father's smartphone screen. In the recorded list of FIG. 5, the [NEW] icon is deleted from the recorded content that has been played back (in the example of FIG. 5, the women's golf open “BBBB”). Also, if playback is in progress, the stop position is used as resume position information, stored in the resume position information of the playback information 1 of the playback information related to the father's smartphone shown in FIG. Stores “reproduced (with reproduction)”.

  FIG. 6 shows a state in which a recording list is displayed when a mother and a child who are family members using the same recording / reproducing apparatus 100 use their respective smartphones. In the recording list of the mother's smartphone screen in FIG. 6A, the [NEW] icon is deleted from the recorded content that has been reproduced (in the example of FIG. 6A, the midsummer drama special “AAA”). If playback is in progress, the stop position is used as resume position information, stored in the resume position information of the playback information 2 of the playback information (registered smartphone identification information at the time of pairing) of the mother smartphone shown in FIG. Stores “reproduced (with reproduction)”. Similarly, in the recording list of the smartphone screen for children shown in FIG. 6B, the [NEW] icon is deleted from the recorded content that has been played back (in the example of FIG. 6B, comedy live “DDDDDD”). . If playback is in progress, the stop position is used as resume position information, stored in the resume position information of the playback information 3 of the playback information (registered smartphone identification information at the time of pairing) of the smartphone for children in FIG. Stores “reproduced (with reproduction)”.

  In this way, since each family member has playback information for each recorded content, a program viewed by someone else is prevented from being played back by deleting the [NEW] icon in the recording list on their smartphone screen. it can.
