Method and system for controlling peripheral devices connected to a video device
First Claim
1. A method for identifying predetermined peripheral devices connected to a video device over serial communication control lines, comprising:
- (a) transmitting a command to establish connection of a current peripheral device having no given device ID to an upper peripheral device among the predetermined peripheral devices, and transmitting a command to disconnect a connection to a lower peripheral device;
(b) requesting unique device identification information to the predetermined peripheral devices;
(c) receiving a response to the request from the current peripheral device; and
(d) giving a device ID to the current peripheral device.
