Transport of High Bit Rate Media Signals over IP Networks

In the current era of the new media, because of the influence of new media, the traditional radio and television is transforming to the IP network structure. This paper has referred the standard SMPTE ST2022-6-2012 to detail of the high bit rate media signals transmission in the IP network data mapping. protocol encapsulation and requirements. It has given a brief introduction to the trend of television center's infrastructure trans to IP network development status. This paper analyzes the real-time transport protocol to study a number of issues which associated with reliable real-time transmission, including audio and video data compression and decompression, transmission protocol encapsulation header format. SMPTE ST2022 defines the encapsulation formats and transmission standards of professional baseband IP video signal. To achieve SDI over IP technology, it has to convert SDI signal into data and network environment, so that it can establish comprehensive network transmission and data error correction protocol.
