METHODE FOR CONTROLLING COMPLEX DEVICE IN DEVICE LINK SYSTEM BASED TELEVISION

摘要

A method for controlling complex devices in a device link system based on a TV is provided to more efficiently and conveniently operate and control a specific device by connecting various types of devices to a digital TV by a daisy chain type and operating a remote controller of the digital TV. A master device of a device link system based on a TV generates a request message to discover respective slave devices, and transmits the generated request message. The respective slave devices receive the request message, generate a response message, and transmit the generated response message to the master device. A physical ID and a logical ID indicating all of the slave devices are recorded in a destination address of the request message. When the corresponding slave device is a complex device, an intrinsic physical ID and a meaningless logical ID are recorded in a source address of the response message.
