Abstract

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.

Claims

1. An AV device system comprising a plurality of input devices for generating an input AV signal, a related device for recording and reproducing said AV signal, a display device for displaying said AV signal, and a bus connecting said input devices, said related device and said display device for transmitting or receiving the AV signal and the management information,

wherein said related device includes a recording medium for recording the AV signal, and said input devices each include means for transmitting the information requesting said related device to secure a recording area in the recording medium of said related device.
