RTP-BASED LOSS RECOVERY AND QUALITY MONITORING FOR NON-IP AND RAW-IP MPEG TRANSPORT FLOWS
First Claim
1. A method, comprising:
- transmitting a transport stream formatted according to a defined coding specification to a receive-and-process (RP) system, the transport stream format further comprising a non-Internet protocol (IP) format or a raw-IP format;
providing a mapping stream, the mapping stream correlating the transport stream to a Real-time Transport Protocol (RTP)-formatted data stream that encapsulates the transport stream, the mapping stream comprising identifying information corresponding to the transport stream and second identifying information corresponding to the data stream; and
transmitting the mapping stream to the RP system over an IP connection to enable RTP capabilities at the RP system.

Abstract
In one method embodiment, transmitting a transport stream formatted according to a defined coding specification to a receive-and-process (RP) system, the transport stream format further comprising a non-Internet protocol (IP) format or a raw-IP format; providing a mapping stream, the mapping stream correlating the transport stream to a Real-time Transport Protocol (RTP)-formatted data stream that encapsulates the transport stream, the mapping stream comprising identifying information corresponding to the transport stream and second identifying information corresponding to the data stream; and transmitting the mapping stream to the RP system over an IP connection to enable RTP capabilities at the RP system.

14. A system, comprising:
a Real-time Transport Protocol (RTP) encapsulator comprising encapsulation logic, the encapsulation logic capable of RTP encapsulating non-Internet Protocol (IP) flows and raw-IP flows, the RTP encapsulator further configured to generate a mapping stream that correlates respective identifying information of packets in the non-IP flows or raw-IP flows with RTP packets of the RTP encapsulated non-IP or raw-IP flows, the non-IP flows comprising non-encapsulated Moving Picture Experts Group (MPEG)-2 transport stream (TS) flows, the raw-IP flows comprising IP/User Datagram Protocol (UDP)/MPEG2TS flows, the mapping stream delivered over an IP connection to a receive-and-process (RP) system, the RTP encapsulator further configured to optionally provide RTP-encapsulated forward error correction (FEC) packets to the RP system. - View Dependent Claims (15, 16, 17)

18. A system, comprising:
a receive-and-process (RP) system capable of receiving a non-Internet Protocol (IP) media content stream and a raw-IP media content stream each carried as a transport stream over an in-band communication and configured to receive a mapping stream over an IP connection, the RP system further configured to synchronize the non-IP or raw-IP media content stream with a Real-time Transport Protocol (RTP) data stream based on first and second identifying information of the media content stream and the data stream, respectively, the mapping stream comprising the first and second identifying information, the RP system incapable of receiving RTP-encapsulated transport stream flows and configured to provide RTP functionality based on the mapping stream. - View Dependent Claims (19, 20)
