Abstract
A method for correcting packet errors in a combined stream including steps of receiving a combined and re-packetized transport stream comprising program information for at least two transport streams (A and B), wherein each transport stream (A and B) comprises program information associated with respective distinctive packet IDs (PIDs), detecting an invader packet associated with the combined and re-packetized transport stream A does not belong in the combined and re-packetized transport stream A, offering the invader packet to combined and re-packetized transport stream B in which a gap is detected, and de-combining combined and re-packetized transport stream B such that information from a de-combined version of the invader packet fills a gap in a de-combined version of combined and re-packetized transport stream B.
