Abstract
In embodiments of the present invention improved capabilities are described for digitally transmitting audio that is converted from analog audio received from analog media pickup devices in a live performance venue by a stage box to a base unit over off-the-shelf twisted pair cable while sending pre-amplification control signals and power over the cable to the stage box. Audio for the performance venue is remotely managed from a virtual audio engineering mixing board that wirelessly communicates audio control commands to the stage box from a handheld computing device.
Claims14
A system comprising:
- at least one video pickup device;
- and
- a plurality of stage boxes interconnected in a daisy-chain with at least one base unit,
- wherein a first stage box of the daisy-chain:
- receives a video signal from the at least one video pickup device,
- receives a multiplexed video signal from a second stage box in the daisy-chain;
- multiplexes the video signal with the multiplexed video signal producing a combined multiplexed video signal;
- and
- transmits the combined multiplexed video signal over the daisy-chain to the at least one base unit;
- wherein the at least one base unit:
- demultiplexes the combined multiplexed video signal into a plurality of video signals;
- and
- powers the plurality of stage boxes via a power signal over the daisy-chain that is physically distinct from the combined multiplexed video signal.

A method, comprising:
- interconnecting a plurality of stage boxes and a base unit in a daisy-chain;
- receiving, at a first stage box of the plurality, a video signal from a media pickup device;
- receiving, at the first stage box, a multiplexed video signal from a second stage box of the plurality;
- multiplexing the video signal with the multiplexed video signal thereby producing a combined multiplexed video signal;
- transmitting the combined multiplexed video signal over the daisy-chain to the base unit;
- demultiplexing the combined multiplexed video signal at the base unit into a plurality of video signals;
- and
- powering the plurality of stage boxes by transmitting power from the base unit through the daisy-chain.
