SMPTE ST 2022-4 – Unidirectional Transport of Non-Piecewise Constant Variable Bit Rate MPEG-2 Streams on IP Networks

This standard defines a transport protocol for the carriage of real-time non-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 non-piecewise constant VBR transport stream has no predictable time base to reconstruct the signal if the inter-packet timing is altered in transit through the network. This standard defines two methods to maintain the inter-packet timing through the non-synchronous IP network transport. 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.
