Synchronizing redundant video streams encapsulated in IP/UDP packets
Abstract
An apparatus, e.g., in a network edge device, a method, and a software program product for synchronizing two or more redundant media streams, e.g., MPEG video streams. The method includes receiving network packets encapsulating redundant media streams representing the same media program, buffering the received streams, learning a program identifier for the media program, searching the packets of the redundant streams for synchronization points defined by a plurality of parameters of stream packets, synchronizing the redundant streams based on the comparison, and providing a single stream as an output stream.
