Patent ID: 7174560

Claim:
A transmitter capable of transmitting synchronization data for synchronizing information other than audio or video with at least one of audio or video, said transmitter comprising: (a) an application time clock that determines a rate of data entering at least one of an audio encoder or a video encoder, each sending data to a multiplexer in first and second data streams, respectively; (b) a 27 MHZ system clock operatively interconnected to said multiplexer; (c) a data server having storage storing said information other than audio or video; (d) a first packetizer that packetizes said information other than audio or video and sends packetized said information to said multiplexer in a third data stream separate from said first and second data streams; (e) a clock sampler sampling said application time clock; and (f) a second packetizer, apart from said first packetizer, that packetizes samples of said application time clock and sends said packetized samples to said multiplexer in a fourth data stream separate from said first, second, and third data streams.
