  In the first embodiment, the reservation information generating unit 200 provided in the controller 110 will be described in detail.

  The reservation information generating unit 200 generates the recording reservation information of the video content so that the other device can read it, and records it in the detachable recording unit 151. The recording reservation information is, for example, the broadcast date and time of the broadcast program to be recorded, the channel, the bit rate at the time of recording, and the like. For example, similar to the video playback device 1A, the other device satisfies the SeeQVault standard, can be connected to the recording unit 151 via the USB terminal, and has the recording reservation information and the recording reservation request generated by the reservation information generation unit 200. This is a video playback apparatus 1B capable of reading the presence / absence flag.

  Even if the video playback apparatus cannot read the recording reservation information and the recording reservation request presence / absence flag generated by the reservation information generating unit 200, the recording unit 151 reads the data of the recording reservation information and the recording reservation request presence / absence flag. By recording a program that can be recorded, it is possible to update the software of the CPU 1100 so that the recording reservation information can be read.

  As described above, the reservation information generating unit 200 creates a data area for determining whether or not there is a recording reservation request in the storage overall management file 30 in the recording unit 151. Specifically, a recording reservation request presence / absence flag indicating whether or not to request a recording reservation to another device (for example, the video playback device 1B) is recorded in the storage overall management file 30 as either ON or OFF. The reservation information generating unit 200 updates the recording reservation request presence / absence flag.

  For example, the video playback device 1B reads the recording reservation information recorded in the recording unit 151 if the recording reservation request presence / absence flag is ON, and if the recording reservation request presence / absence flag is OFF, it is recorded in the recording unit 151. Do not read the recording reservation information.

  Next, an operation when the recording unit 151 in which the data file is recorded is connected to another apparatus (video reproduction apparatus 1B) that can read the recording reservation information and the recording reservation request presence / absence flag will be described.

  In the video playback device 1B to which the detachable recording unit 151 is connected, for example, the CPU incorporated in the video playback device 1B reads that the recording reservation request flag is ON and reads the recording reservation information. The recording reservation information includes an instruction to display on the display a display screen as to whether or not recording is permitted in the video playback device 1B. When the video playback device 1B performs recording based on the recording reservation information, the read recording reservation information is recorded, for example, in a nonvolatile memory built in the video playback device 1B, and at the date and time recorded in the recording schedule information. Recording is performed. When reading that the recording reservation request flag is OFF, the video playback device 1B does not read the recording reservation information recorded in the recording unit 151.

  As described above, by recording the recording reservation information in the removable recording unit 151, the recording unit 151 is connected to a different video playback apparatus from the video playback apparatus connected when the recording reservation is made. However, the desired video content can be recorded.

  FIG. 4 and FIG. 5 are the processes performed in the recording unit 151 when there is a request for updating ON / OFF of the recording reservation request presence / absence flag and when there is a request for updating the recording reservation information. The description will be given with reference.

  For example, when a key on the remote controller is pressed, a request for ON / OFF switching of the recording reservation request presence / absence flag recorded in the recording unit 151 is requested ([40]), and the recording reservation request presence / absence flag is updated to ON. When requested ([42]), the recording reservation request presence / absence flag in the overall storage management file 30 is turned on ([44] -YES). Subsequently, the recording reservation information in the overall storage management file 30 is updated ([46]), and the process is terminated. Also, for example, when there is a request to update the recording reservation request presence / absence flag recorded in the recording unit 151 to OFF by pressing a key on the remote controller ([42]), The recording reservation request presence / absence flag is turned off ([44] -NO), and the process ends.

  Also, for example, when there is a request to update the recording reservation information by pressing a key on the remote control ([50]), the ON / OFF of the recording reservation request presence / absence flag in the overall storage management file 30 is updated. ([52]). Subsequently, the recording reservation information in the storage overall management file 30 is updated ([54]), and the process is terminated.

  Next, referring to FIG. 6, when the detachable recording unit 151 is connected to another apparatus (for example, the video display device 1B) that can read the recording reservation information, the recording reservation request is displayed on the display. The flow until the user is permitted will be described.

  First, when the recording unit 151 is connected to another device, the other device checks whether the recording reservation request flag is ON ([60]). If the recording reservation request flag is OFF (60-NO), the process is terminated. If the recording reservation request flag is ON (60-YES), based on the recording reservation information in the recording unit 151, a screen as to whether or not to permit recording reservation is displayed on the display ([62]). If the user does not permit recording reservation on the displayed screen ([64] -NO), the process is terminated. If the user permits the recording reservation on the displayed screen ([64] -YES), the other device records the recording reservation information stored in itself and the recording reservation information in the connected recording unit 151. Are merged ([66]). (Merging of data means, for example, that all the programs scheduled to be recorded recorded in other devices and all the programs scheduled to be recorded recorded in the recording unit 151 are treated as programs scheduled to be recorded. If there is no time zone in which the number of programs that can be recorded at the same time exceeds the allowable amount in the merged recording reservation information from the relationship of the number of tuners provided in the other device ([68] -NO), the processing is performed. finish. When there is a time slot in which the number of programs that can be recorded simultaneously exceeds the allowable amount ([68] -YES), a screen for selecting which recording reservation to delete is displayed, and any recording reservation is made according to the user operation. Delete ([69]). Thereafter, the above process is repeated until the program recorded in the recording reservation information recorded in the recording unit 151 can be recorded.

  Next, a case where the recording unit 151 in which the recording reservation information is recorded will be described with reference to the flowchart of FIG. When a recording reservation request is permitted when the recording unit 151 is connected to another device, if an instruction to release the connection between the recording unit 151 and the other device is input, the recording is recorded on the display unit of the other device. A selection screen as to whether or not to delete the recording reservation requested by the unit 151 is displayed ([70]). If the user does not select to delete the permitted recording reservation information ([72] -NO), the process ends. When the user selects to delete the permitted recording reservation information ([72] -YES), the recording reservation information for recording the program to the recording unit 151 that has been disconnected is recorded from the recording reservation information recorded on the other device. The information is deleted ([74]) and the process is terminated.

  As described above, according to the video reproduction apparatus and the recording management system of the first embodiment, even if there is a period when the storage device is not connected to the own device, the reservation information generated by the own device is used. Data recording is possible.
