Abstract
A communication protocol over the serial bus allows a peripheral device to control the flow of data between a host computer and the peripheral device so as to maintain synchronization to a periodic reference signal. The protocol involves transferring flow control messages between the peripheral device and the host computer, allowing the peripheral device to control how and when the host computer sends the uncompressed audio and video data.
