Abstract

A computer system and method providing for viewing and switching of audio-video data. The system comprises: a plurality of audio/video sources containing information referring to an event; a streaming server (11), streaming the contents of a first audio signal and a first video signal from the audio and video sources to a user; a feed distributor (13) controllably feeding the first audio signal and first video signal to the streaming server (11); and a user-operated control unit (14) communicating with the feed distributor (13) and controlling operation of the feed distributor (13), so as to instruct the feed distributor (13) to switch between audio or video. Switching between audio signals occurs without altering the video signals and switching between video signals occurs without altering the audio signals.
