ABSTRACT:
A method and apparatus for initializing and determining the topological configuration of a system for processing video information is described. The system has a master device and multiple slave devices for transmitting or receiving video information. The master and slave devices are coupled together in a daisy chain by a serial video link. The master device issues commands to the slave devices to selectively control the routing of a video data stream within each of the slave devices. The master transmits the video data onto the serial video link to the slave devices and assigns a unique address to each of the slave devices based on the responses of the slave devices to the commands and the transmitted data stream. The master device also determines the position in the daisy chain of each of the slave devices based on those responses.
