Abstract: The growth of internet protocol (IP)-based service in the national and international markets has been tremendous, and the traffic volume is comparable to that of ordinary voice. At the same time, the cost of IP technology is considerably less than that of asynchronous transfer mode (ATM) and synchronous digital hierarchy (SDH). The consequence is that telecom operators are constructing new IP networks with the intent to convert all services to IP. The result for the broadcaster is that it will be more economical to base new contribution and distribution networks on IP. The Pro-MPEG Forum has proposed two standards for transport of video over IP. Code of Practice #3 (CoP3) covers transport of compressed video in the form of MPEG-2 transport streams. This standard is well advanced, and equipment is available from several vendors, as was demonstrated at the SMPTEA/idTrans 2006 Conference. Code of Practice #4 (CoP4) is similar to CoP3 and concerns transport of uncompressed video—serial digital interface (SDI). This paper describes the experience with using CoP4 for contribution. In addition, the paper includes a description of the standard and a tradeoff for SDI transport.
