Abstract
Method and apparatus for determining a transport bit rate for a multiprogram transport stream (MPTS) is described. In one example, a plurality of transport bit rates is computed for a respective plurality of programs in the MPTS. A highest transport bit rate and a lowest transport bit rate are selected from the plurality of transport bit rates. An average transport bit rate is computed from the highest transport bit rate and the lowest transport bit rate. The average transport bit rate is provided as an initial transport bit rate for the MPTS. Jitter in the MPTS may be compensated using the initial transport bit rate.
