Abstract
Multimedia distribution systems are disclosed in which servers communicate with clients via audio, video, overlay and/or control channels. Information sent between the clients and servers on the audio, video and/or overlay channels includes timestamps. The timestamps coordinate the queuing and processing of information received by the client. Once information has been processed by the client, the client can report information concerning the timestamps associated with the processed information to the server. In one embodiment, the invention includes a server connected to a client via a network. In addition, at least one server is configured to communicate audio, video, overlay and control information with a client via separate audio, video, overlay and control channels, information transmitted on at least one of the audio, video and overlay channels includes time stamps, the client is configured to process the audio, video and overlay information for output to one or more rendering devices and the client is configured to transmit information concerning time stamps of processed information to the server via the control channel.
