Abstract:
A system allocates channel bandwidth based on the data received from a plurality of remote sources. A de-multiplexer/priority circuit separates two or more different data streams into their components parts. A stream modification driver modifies one or more characteristics of the data received from the de-multiplexer/priority circuit based on a priority assigned to the data by the de-multiplexer/priority circuit. The de-multiplexer/priority circuit determines the data transfer rates for each of the different data streams based on the assigned priority.
