  • Patent number: 9510060
    Abstract: A system, apparatus, and method provide the ability to process media content streams. A primary and backup multiplexer are each configured to receive and multiplex multiple video streams to output IP multicast streams with unique unicast addresses. A primary and backup uniform transport processing system (UTPS) join the IP multicast streams and output each stream using a unique multicast group. Multiple virtual local area networks (VLANs) separate the joins of the primary UTPS from the joins of the backup UTPS. Primary and backup modulators join the IP multicast streams output from the primary or backup UTPS and convert the joined stream to radio frequency for uplink to a broadcast distribution network.
