Abstract:
1. A computer-implemented method for reducing the bandwidth of MPEG transport streams during transmission over a packet-switched network, said method comprising: identifying, by one or more computing elements, characteristics of a plurality of media fragments disposed within each of a plurality of packets of a transport stream, wherein the characteristics define one or more of: one or more MPEG frames, one or more audio frames, PSI, and stuffing content; aggregating, by the one or more computing elements, the identified characteristics into a summary value for each of the plurality of packets; correlating, by the one or more computing elements, the summary value to a priority weighting identifiable by one or more network elements; and marking, by the one or more computing elements, each of the plurality of packets with the priority weighting, wherein each of the plurality of packets are configured for being selectively dropped by the one or more network elements in accordance with their priority weightings to reduce the bandwidth of the transport stream.
