AUDIO-VIDEO DATA SWITCHING AND VIEWING SYSTEM
First Claim
1. A method for switching between streams of audio data transmitted to a plurality of users over a packet-switching network, comprising:
- establishing separate connections with each of said plurality of users over the network;
streaming first audio data in a first stream from at least one server to at least one of said plurality of users via at least one of said connections;
for at least one of said plurality of users, switching the first stream with a second stream comprising second audio data that is different from the first audio data, wherein only one of said first and second streams is transmitted to a user at a time, and wherein;
(a) the first audio data and the second audio data comprise differentially compressed data;
(b) the first stream comprising first audio data and the second stream comprising second audio data each comprise one or more key frames; and
,(c) the first stream comprising first audio data switches to the second stream comprising second audio data at said one or more key frames.

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, 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 controllably feeding the first audio signal and first video signal to the streaming server; and a user-operated control unit communicating with the feed distributor and controlling operation of the feed distributor, so as to instruct the feed distributor 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.
