Abstract
A method to determine placement of sampled data within a data stream of a fixed rate communication channel is disclosed. The fixed rate communication channel transfers a serial flow of data packets over a serial or parallel communication channel. Each data packet has a header and a data stream. The method for transferring variable rate sampled data to a fixed rate communication channel begins by acquiring a sample of the variable rate sampled data. A data packet in which to place the sample is then determined. A location within the data stream where the sample is to be placed is also determined. A pointer to the location is placed within the header of the data packet. The sample is placed within the location within the data stream of the data packet and the data packet is then transmitted on the fixed rate communication channel.
