High Bit Rate Media Transport
High Bit Rate Media Transport (HBRMT) formerly known as High Bit Rate Audio Video Over IP (HBRAV-IP), is a standard for
data encapsulation and
forward error correction
In computing, telecommunication, information theory, and coding theory, an error correction code, sometimes error correcting code, (ECC) is used for controlling errors in data over unreliable or noisy communication channels. The central idea i ...
(FEC) of high bit rate contribution oriented video/audio feed services, up to 3 Gbit/s over
Ethernet networks. HBRMT is published as parts 5 and 6 of SMPTE 2022 by the SMPTE 32NF networking technology committee. HBRMT supports both
