<p>A method for real-time transporting H.264 multimedia video data is disclosed, it makes that the RTP protocol could efficiently carry H.264 multimedia video data, and enhances the ensuring mechanism of the service quality on the premise of being compatible with the known apparatus and transport manners with RTP protocol. A modified RTP protocol for carrying H.264 data is disclosed, by combing all header information bytes of H.264 NALU into the header information of RTP packet itself, so as not to affect the action of known RTP protocol and apparatus, and it could directly indicate the attribute of H.264 NALU payload in the MRTP header information; further an identification method for discriminating the known RTP from MRTP is provided, by modifying the relevant fields such as M, F field of the known RTP header information, this makes it possible that the known network media apparatus could support both RTP and MRTP to work, and improves the compatibility of MRTP and the flexibility of application.</p> |
