Redundant universal transport processing system

摘要

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.

1. A system for processing media content streams comprising:
(a) a primary multiplexer and a backup multiplexer that are each configured to:
(i) receive multiple video streams from one or more video sources; and(ii) multiplex the multiple video streams to output one or more internet protocol (IP) multicast streams with unique unicast addresses, each IP multicast stream corresponding to a unique multicast address, wherein a subnet portion of the unique multicast address for each video stream is shared between the primary multiplexer and the backup multiplexer; (b) a primary uniform transport processing system (UTPS) and a backup UTPS, wherein:
(i) the primary UTPS and the backup UTPS each join the one or more IP multicast streams output from either the primary multiplexer or the backup multiplexer;(ii) multiple virtual local area networks (VLANs) separate the joins of the primary UTPS from the joins of the backup UTPS; and(iii) the primary UTPS and the backup UTPS each output each of the one or more IP multicast streams using a unique multicast group; and (c) one or more primary modulators and one or more backup modulators, wherein each of the one or more primary modulators and one or more backup modulators:
(i) join one of the one or more IP multicast streams output from the primary UTPS or backup UTPS; and(ii) convert the joined IP multicast stream to radio frequency for uplink to a broadcast distribution network.
