Abstract
A system for transmitting and distributing audio or video information. The system includes a plurality of input modules arranged in series along at least one chain of high speed serial data links that end with a master module. Each input module receives mixing instructions addressed to that module and then passes a signal mixed in accordance with the instructions to the next input module in the chain where no human perceptible delay is introduced into the mixed signal as it moves through the chain.
