Even when a failure occurs in any of the terminal devices, the entire system can continue to operate.

Next, in the above embodiment, each operation of receiving, recording, and reproducing a television broadcast will be described using the flowchart shown in FIG.
Here, embodiments of the operation control method and the operation control program according to the present invention will be described together.

First, prior to all processing, the processor 4 of the terminal device D1 stores the terminal information of all terminal devices input from the external input device 12 via the external input / output control device 5 in the storage device 3 (S101: Terminal information input process). Subsequently, this terminal information is distributed to all other terminal devices D2, D3,... Via the LAN transmitting / receiving device 2 (S102: terminal information distribution step). Here, by the the terminal information input step and the terminal information distribution process, end end information registration process is composed.

  Subsequently, the processor 4 of the terminal device D1 inputs a schedule of processing contents including processing allocation to all the terminal devices D1, D2, D3... Inputted from the external input device 12 via the external input / output control device 5. Are stored in the storage device 3 and distributed to all other terminal devices D2, D3,... Via the LAN transmitting / receiving device 2 (S103: schedule registration step). Note that the processing assignment for the terminal devices D1, D2, D3... Is not limited to an external input, and the optimum terminal device having the smallest load for executing the processing from the terminal information in the processing of the terminal selection processing unit 42 of the processor 4 Can also be selected and assigned.

  Here, the terminal information registration process (including the terminal information input process and the terminal information distribution process) and the schedule registration process described above are programmed to be executed, and this is configured to be realized by a computer. Also good.

Next, the terminal device D1 confirms the operation status of each of the other terminal devices D2, D3,... By the operation of the monitoring processing unit 41 of the processor 4, and determines whether there is a faulty device (S104: fault monitoring step). ). If there is a faulty terminal device, the process proceeds from the symbol “A” in FIG. 2 to the symbol “A” in the fault processing flowchart of FIG. 3 (S105).
The processor 4 reads out the processing content from the schedule stored in the storage device 3 at regular time intervals (S106) and sends it to the television tuner 1. In the case of television reception, a television video signal input from the antenna 10 is sent to the television tuner 1.

When the received TV video signal is designated in advance to be processed by the terminal device D1 (S107), the processor 4 converts the TV video signal into a format that can be processed by the processor 4 for the TV tuner 1. And instruct the processor 4 to send it. The TV tuner 1 transmits a TV video signal to the processor 4 according to the instruction (S108).
When the recording process of the TV video signal is designated, the processor 4 processes the TV video signal into a format suitable for the subsequent steps (S109).

As a subsequent process, when the display process is specified in step S110 shown in FIG. 2, the processor 4 transmits the processed television video signal to the external input / output control device 5 (S111). The external input / output control device 5 transmits the TV video signal to the external output device 13 which is a display device (S112). The external output device 13 displays the transmitted television video signal (S113). If the internal storage is designated in step S110 shown in FIG. 2, the processor 4 outputs the processed television video signal to the storage device 3 (S114), and the storage device 3 stores this data. (S115).

If it is specified in S110 that the TV video signal is stored or displayed by another device, the processor 4 transmits the TV video signal to the LAN transmitting / receiving device 2 (S116). The LAN transmission / reception device 2 converts the television video signal into a format capable of LAN transmission, and transmits the television video signal to the designated device (S117).
When the terminal device D1 specifies that the TV video signal received by the TV tuner of another device is stored or displayed, the processor 4 instructs the LAN transceiver device 2 to transmit the received data to the processor 4, A TV video signal is received from the LAN transmitting / receiving device 2 (S118), and recording, display, and processing are executed.
The above is the normal operation.

  Next, an operation when a failure occurs in a part of the terminal devices D1, D2, D3... During the operation of the system described above will be described.

The operation when a failure occurs in the terminal device D1 is as follows.
First, the terminal devices D1, D2, D3... Regularly monitor each other's state via the LAN transmitting / receiving device 2 (S102: failure monitoring step). When a failure occurs in the terminal device D1, the terminal device D1 does not respond to communication from the other terminal devices D2, D3,. Thus, the occurrence of a failure is determined (S201).
In each terminal device D1, D2, D3..., A schedule such as recording is stored in the storage device 3, and the processor 4 of the terminal device reads the information (S202), and the terminal device D1 performs the current processing. It is searched whether it is in the middle of processing (S203) or whether it is scheduled to be processed (S204).

When the terminal device D1 is currently executing the processing, the processor 4 of the other terminal device verifies the contents processed by the terminal device D1, and selects the next suitable device after the terminal device D1. Then, the processing that the terminal device D1 was immediately performing on the corresponding device is continued (S206: terminal selection step, processing content continuation processing step). At the same time, the processor 4 of each terminal device changes the processing content and saves it in the storage device 3 (S207 : allocation change control function ).
Here, in the above-described fault monitoring process, terminal selection process, and process content continuation process process, the execution contents in each process may be programmed and realized by a computer.

When the terminal device D1 is not processing and there is no plan to process, the processor 4 stands by without changing the schedule (S204).
When the terminal device D1 is scheduled to be processed, the processor 4 verifies the content processed by the terminal device D1, selects a device that is suitable next to the terminal device D1, changes the schedule, and stores it in the storage device 3. The data is stored and distributed to other terminal devices (S205: schedule change step). Conversely, when data processed by the processor 4 is input from another terminal device (S119), the input data is stored in the storage device 3 (S120).

In the present system, pre-planned and receiving and recording or the like, the performance of each terminal device is inputted in advance every each such terminal. The schedule of the reception and recording or the like, is intended future operation and start time of receiving and recording occurs, record the allocation terminal device or the like.
The system user can schedule recordings or the like according to a schedule set independently from the external input devices 12A, 12B, 12C,... Of the terminal devices D1, D2, D3. , D3... Terminal information is input. The external input device 12 passes the input information to the processor 4 via the external input / output control device 5. The processor 4 updates the recording schedule information based on the passed information. Alternatively, information on each terminal device is updated.

The terminal information showing the performance of each terminal device D1, D2, D3... Records information such as the TV tuner 1, storage device 3, processor 4, and external output device 12A that each device has. When the system user inputs a schedule such as recording based on this information, the processor 4 of the input terminal device selects the terminal device with the least load and completes the schedule (information update control function) .
Further, the processor 4 distributes the updated terminal information and schedule information to the other terminal devices via the LAN input / output device 2 (update information distribution control function) .

Here, the terminal devices D1, D2, D3... May be determined in advance between the terminal devices, in order of priority to execute processing allocation or schedule change among other terminal devices. Alternating ranks may be assigned alternately (assignment update control function) .
The external input / output devices 12 and 13 are not necessarily provided in all the terminal devices. If the external input / output devices 12 and 13 are provided in any one of the terminal devices D1, D2, D3. An input can be received through the LAN input / output device 2 and an output can also be performed without any trouble by a method such as displaying it on another terminal device through the LAN input / output device 2.
