Abstract
A method of generating timestamps for isochronous data includes locking a data stream time and an isochronous network time to a local clock signal such that a bi-directional mapping may be made between the two time domains. Timing information is extracted from both IEEE 1394 based data packets and a conventional house reference signal in order to obtain scale and offset factors that exist between the two signals. The scale and offset factors are applied to a generated video clock signal in order to predict a future video time in terms of IEEE 1394 time.
