This standard defines a unidirectional IP-based protocol for the transport of real-time video, audio, and ancillary signals. In particular this standard defines a method for the encapsulation of the payloads of a variety of existing SMPTE serial digital video standards.
The term High Bit Rate is used herein to distinguish from other Media-over-IP applications in which compressed signals are transported. The uncompressed signals in this document are at rates of 270 Mbits/sec and higher.
