Abstract: A system and method for performing echo suppression on a server in browser-based online audio conferences without downloading or installing software on a participant's computing device is disclosed. Streams of audio communication data from the participants in an audio conference are received at the server. An echo suppression application determines the first party that speaks by analyzing the streams to locate speech data, and assigns that party as the “owner” of the audio channel. The speech data is sent to the other participants in the conference. The application then determines whether newly received audio from the owner of the channel is new speech; if so, then the party remains the owner of the channel, and the new speech data is also sent to the other parties in the conference. The channel is surrendered if no new speech is received from the owner in a defined period, and the next party that speaks becomes the new owner of the channel. The other audio data from the participants is replaced by silence.

Abstract: An automated electronic application delivery system for delivery software applications to client devices for which they were not originally intended for or developed. The applications are run on the particular application environment at the server side, and the content output by the application is capture, encoded, and streamed to the client devices in a way that minimizes latency. User interacts with the content and such interaction data is either mapped to a specific command catered to the application either at the client side or the server side. The mapped command or raw interaction data is then provided to the application over a control channel.
