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, wherein the video device and the predetermined peripheral devices are connected to one another in a daisy-chain scheme, comprising:
- (a) transmitting a command to disconnect a connection between the predetermined peripheral devices and their lower peripheral device to the predetermined peripheral devices;
(b) requesting unique device identification information from the predetermined peripheral devices;
(c) receiving a response to the request from a current peripheral device having no given device ID;
(d) producing and giving a device ID to the current peripheral device;
(e) transmitting a command to establish a connection between the current peripheral device having the given device ID and its lower peripheral device; and
(f) repeating steps (b) through (e) until a device ID is allocated to all the predetermined peripheral devices.

Abstract
A method and apparatus for effectively performing optimal connection configuration by recognizing the connection status between a video device and external peripheral devices. The method for identifying predetermined peripheral devices connected to a video device over serial communication control lines, includes, transmitting a command to establish connection of a current peripheral device having no given device ID to its upper peripheral device among the predetermined peripheral devices, and transmitting a command to disconnect a connection to its lower peripheral device; requesting unique device identification information to the predetermined peripheral devices; receiving a response to the request from the current peripheral device; and giving a device ID to the current peripheral device.

5. A video device for identifying peripheral devices connected to a video device over a communication control line, wherein the video device and the peripheral devices are connected to one another in a daisy-chain scheme, comprising:
-
a packet transceiver unit for transmitting a signal to request unique device identification information from a first peripheral device of the peripheral devices, receiving a response signal to the signal, and transmitting connection establishing and disconnecting signals to and from the first peripheral device; a packet generating unit for producing the request signal in a form having a predetermined protocol; and an ID generating unit producing and giving a unique device ID to the first peripheral device; wherein the produced unique device ID is transmitted to the first peripheral device. - View Dependent Claims (6)

7. A peripheral device for allowing the peripheral device connected to a video device over a communication control line to be identified by the video device, wherein the peripheral device is connected to the video device in a daisy-chain scheme, comprising:
-
a packet transceiver unit for receiving from the video device a packet to request unique device identification information from the peripheral device, and transmitting a response packet to the requesting packet if a device ID is not allocated to the peripheral device; a packet generating unit for producing the response packet in a form having a predetermined protocol; and a memory unit for storing a device ID that is allocated by the video device in response to transmitting the response packet. - View Dependent Claims (8)
