ST 2022-3:2019 - SMPTE Standard - Unidirectional Transport of Variable Bit Rate MPEG-2 Transport Streams on IP Networks

This standard defines a transport protocol for the carriage of real-time piecewise constant variable bit rate (VBR) MPEG-2 Transport Streams over IP networks, either with or without Forward Error Correction for recovery from network transmission errors. A piecewise constant VBR transport stream can only vary at the PCRs of the program under consideration per ISO/IEC 13818-1:2018 § 2.4.2.3. — This standard covers the encapsulation and transmission of MPEG-2 transport streams but does not cover other processes such as MPEG-2 encoding or multiplexing.
