Recording in a recording information response, which is a response to the recording information, is transmitted to the television 100, and the television 100 transmits recording stop information specifying the recorder ID to the video recorder 200, thereby recording from the television 100 to the recorder unit having the recorder ID. Stop control can be performed.

(Embodiment 2)
In the first embodiment, the video recorder 200 creates a recording information response by using a preset recorder ID as the in-device ID. However, in this embodiment, an ID for each communication session (hereinafter referred to as a session ID). Will be described, and the recorded information response is created using the generated session ID as the in-device ID.

  FIG. 8 is a block diagram showing a configuration of a recording / reproducing apparatus control system according to Embodiment 2 of the present invention. In addition, about the structure similar to Embodiment 1, the same code | symbol is attached | subjected and description is abbreviate | omitted.

  The video recorder 400 of the recording / reproducing apparatus control system according to the second embodiment includes, in addition to the configuration of the video recorder 200 of the recording / reproducing apparatus control system of the first embodiment, as shown in the block diagram of FIG. An ID generation unit 402 and an in-device ID management table 403 are provided.

  The in-device ID generation unit 402 generates a random number and generates a session ID as the in-device ID based on the generated random number. For example, as shown in FIG. 9, the in-device ID management table 403 holds a session ID and a recorder unit selected to perform recording in association with each other.

  The operation of the recording / reproducing apparatus control system of the second embodiment configured as described above will be described. The operation added to step S6, step S14, and step S15 of the first embodiment will be described with reference to FIGS.

  In step S6, the multiple recorder unit control unit 401 does not create a recording information response in which the recorder ID of the recorder unit that performs recording at the time of creating the recording information response is input as it is as the in-device ID. The unit 402 is instructed to create a session ID. The in-device ID generation unit 402 generates a random number and generates a session ID based on the generated random number. Then, the multiple recorder unit control unit 401 creates a recording information response in which the session ID is input as the in-device ID value. In addition, an operation of recording the correspondence relationship between the session ID and the recorder unit selected to perform recording at the timing of creating the recording information response in the in-device ID management table 403 is performed in addition to step S6.

  As described above, when creating the recording information response in step S6, the session ID is input as the in-device ID.

  In step S14, when the multiple recorder unit control unit 401 receives the recording stop information, the multiple recorder unit control unit 401 does not select the corresponding recorder unit as the recording stop target as the recorder ID, but the device ID included in the recording stop information. Instead of referring to the recorder ID directly by referring to the in-device ID management table at the timing when the session ID is acquired as the internal ID, acquiring information indicating which recorder unit the acquired session ID corresponds to. The operation of selecting a recorder unit to stop recording using is added.

  As described above, the session ID is used as the in-apparatus ID when selecting the recorder unit to stop the recording in step S14.

  In step S15, when the multiple recorder unit control unit 401 creates the recording stop information response, the session ID indicating the recorder unit included in the in-device ID management table that is no longer necessary because the recording is stopped for the recorder unit. Add the action of deleting.

  As described above, a new operation is added to step S6, step S14, and step S15 in the recording / reproducing apparatus control system of the first embodiment, so that a session ID is generated in the video recorder 400 every time recording information is sent. Then, this session ID is used as the in-device ID. Therefore, for example, after the recording of the recorder unit in the video recorder 400 that has been performing recording is finished and the same recorder unit is being recorded by a recording operation from another television, the television 100 mistakenly records that recorder unit. Even if the recording stop information is transmitted, since the session IDs included in the recording stop information are different, the video recorder 400 can determine that the current recording should not be stopped. Can be prevented.

  In the first and second embodiments, the tuner 204 described in FIGS. 1 and 8 is a moving image acquisition unit, and the present invention can be applied to any drive such as a hard disk device, SD, CD, or DVD. Can be realized.

  Moreover, in Embodiment 1 and Embodiment 2, although it demonstrated that a user performed recording operation and recording stop operation from the operation input part 101 described in FIG. 1 and FIG. 8, a user does not necessarily perform recording operation and recording stop. There is no need to perform an operation, and the present invention can be realized even when, for example, a reservation is already made on a television to perform recording or recording stop and the television itself performs a recording operation on behalf of the user.

  In the first and second embodiments, the addresses of the television and the video recorder are obtained using the address management table 102 described in FIG. 2, but when the television and the video recorder are directly connected, Since it is not necessary to refer to an address, the present invention can be realized without using an address management table. In addition, although only three devices are described in FIG. 3 in the address management table 102, in order to realize the present invention, a combination of two or more devices including the television itself and an address is sufficient.

  In the first embodiment and the second embodiment, the state management table 103 is a table having a set of three addresses, an in-device ID, and a recording state in FIG. 3, but one or more addresses and in-device IDs are used. And a table having a set of recording states. Further, the present invention can be realized even with a table having only a set of addresses and in-device IDs. In this case, the recording / reproducing apparatus control unit 104 records the set of the address of the video recorder 200 and the ID in the apparatus included in the recording information response in the state management table at the timing when the recording information response is received, and sends a recording stop information response. At the timing of reception, the set of the address of the video recorder 200 and the in-device ID included in the recording stop information response may be deleted from the state management table 103. As a result, the state management table 103 records the set of the address of the video recorder 200 being recorded and the ID in the apparatus.

  In Embodiments 1 and 2, examples of recording information, recording information response, recording stop information, and recording stop information response are shown in FIG. 5 and FIG. Since it is not necessary to distinguish between a television and a video recorder if they are directly connected, the present invention can be realized without an address in recording information, recording information response, recording stop information, and recording stop information response.

  In Embodiments 1 and 2, an example of the recording information is shown in FIG. 5, but if the video recorder is determined to record a predetermined channel number, the channel number is necessary in the recording information. Therefore, the present invention can be realized even if there is no description of the channel number in the recording information.

  In the first embodiment and the second embodiment, FIG. 5 shows an example of the recording information response. However, if the television does not record the recording state, the recording state is not necessary. The present invention can be realized without the description.

However, since it is not always necessary to issue a response to the recording stop information, the present invention can be used without a recording stop information response. Can be realized.

  In Embodiment 1 and Embodiment 2, the in-device ID management table is shown in FIG. 9 as a table having a set of three recorder units and session IDs. The present invention can be realized as long as the table has.

  In the first and second embodiments, the recording / reproducing apparatus control system includes one television 100 that is a control apparatus, but is not limited thereto, and includes two or more control apparatuses. Even in this case, the present invention can be realized.

  Each functional block in the block diagrams shown in FIGS. 1 and 8 is typically realized as an LSI which is an integrated circuit. This LSI may be made into one chip or a plurality of chips. (For example, the functional blocks other than the memory may be integrated into one chip.) Although the LSI is used here, it may be referred to as an IC, a system LSI, a super LSI, or an ultra LSI depending on the degree of integration.

  Further, the method of circuit integration is not limited to LSI, and implementation with a dedicated circuit or a general-purpose processor is also possible. An FPGA (Field Programmable Gate Array) that can be programmed after the manufacture of the LSI or a reconfigurable processor that can reconfigure the connection and setting of the circuit cells inside the LSI may be used.

  Further, if integrated circuit technology comes out to replace LSI's as a result of the advancement of semiconductor technology or a derivative other technology, it is naturally also possible to carry out function block integration using this technology. Biotechnology can be applied.

  Of the functional blocks, the unit for storing data, the tuner 204, and the moving image acquisition unit 205 may be configured separately without being integrated into one chip.

  According to the recording / reproducing apparatus control system of the present invention, the control apparatus can specify a recorder unit in the recording / reproducing apparatus and perform a recording operation for each recorder unit.
