Abstract
Systems and methods for distributing an audio/visual feed of a live event include mixing ambient audio signals, from ambient microphones monitoring the live event, with sound board feed from the event public address system, thereby forming a mixed audio signal. A video input signal is received at each video input in a plurality of video inputs at a video board from corresponding cameras recording the event. One such video input signal is selected as the video board output and is combined with the mixed audio signal thereby producing an audio/visual signal. This signal is encoded using a video codec, at each of several bitrates, and an audio codec, thereby forming bitrate streams each comprising the video portion of the audio/visual signal at a unique bitrate. The streams are received by a satellite router and transmitted to a satellite which sends them to one or more downlink servers for Internet distribution.
