Abstract

The present invention relates to information which allows transmission of time related data over a data communication medium. In one embodiment, a set of data includes at least one instruction to cause a digital processing system to generate a set of packets representing a time related sequence of media data. The set of packets is associated with a transmission protocol. The set of data includes a time related sequence of data which is associated with the time related sequence of media data.
