MULTIPATH RATE ADAPTATION

摘要

An end-to-end multimedia streaming system can include a streaming server and a destination. The streaming server includes a content source, which sends multiple description coding-encoded content over a plurality of paths to the destination. The destination includes an aggregator for aggregating the descriptions from the multiple paths, decoding and recombining them to recover the content. A feedback sender at the destination generates traffic performance variables based on the channel conditions of the multiple paths, and sends these variables to a feedback receiver at the streaming server. The feedback receiver utilizes the feedback information to make adjustments to the transmissions of the content, and to synchronize the transmissions over the multiple paths.
