Method of using AV devices and AV device system |
摘要 |
A plurality of devices and a device system are disclosed, in which a plurality of input devices generate an input AV signal, a related device records and reproduces the AV signal, and a display device displays the AV signal. The input devices, the related device and the display device are interconnected to configure an AV system having a bus for transmitting or receiving the AV signal and management information. The related device of the AV system includes a recording medium for recording the AV signal, and the input devices transmit to the related device a request to secure a recording area on the recording medium. |

1. An audio and video (AV) device for receiving a request for recording an AV signal onto a recording medium, comprising:
a communication unit adapted to transmit and receive a control signal with other devices through a network, where the received control signal is the request for recording the AV signal onto the recording medium at a desired time; a recording unit adapted to record the AV signal including at least one of sound data or image data, onto the recording medium; and a timer reservation unit adapted to check whether or not the recording medium is set to the recording unit in a case where the communication unit receives the request for recording the AV signal at the desired time, and to detect a residual capacity of the recording medium, wherein: the communication unit transmits a control signal for notifying the other device of the recording medium not being set to the recording unit, in a case where the recording medium is not set to the recording unit, the communication unit transmits a control signal for notifying the capacity required for recording the AV signal being available in the recording medium, in a case where the detected residual capacity of the recording medium is more than or equal to the capacity required for recording the AV signal, and the communication unit transmits a control signal for notifying the other device of the residual capacity of the recording medium being less than the capacity required for recording the AV signal, in a case where the detected residual capacity of the recording medium is less than the capacity required for recording the AV signal. |
