Patent ID: 8532311

Claim:
A method, comprising: receiving at a first stage box at least one analog media signal from a media pickup device, digitizing each analog media signal, and multiplexing the digitized signal to produce a first multiplexed digital media signal; transmitting the first multiplex signal from the first stage box over a cable to a daisy-chain second stage box; receiving at the second stage box at least one analog media signal from a media pickup device, digitizing each analog media signal, and multiplexing the digitized signal to produce a second multiplexed digital media signal; multiplexing the first multiplex signal and the second multiplex signal at the second stage box into a combined multiplexed signal; transmitting the combined multiplex signal from the second stage box to a daisy-chain base unit over a cable; demultiplexing the combined multiplex signal at the base unit; and powering each of the daisy-chained stage boxes by transmitting power from the base unit through the daisy-chaining cable to each of the stage boxes.
