Abstract
Rather than utilizing fixed point-to-point remapping of PIDS, the present invention utilizes the type of stream that the PIDS are associated with and the related program services IDs to specify the associations between input and output programs. This permits mapping at the program level and, therefore, allows dynamic responses to input program changes based upon the program mapping references. Resolving PID mapping based upon programs and the included services allows output PIDs to remain constant service-by-service even as the input programs change.
