SMPTE 2019-3 – VC-3 Type Data Stream Mapping over SDTI

This document specifies the mapping of the VC-3 type compressed picture data stream into the SMPTE305M SDTI payload area. The VC-3 type compressed picture data stream mapping is defined for sourcecoded progressive 1080P picture rates of 25/P and 30/1.001/P, 720P picture rates of 50/P and 60/1.001/P,and for interlaced 1080I picture rates of 50/I and 60/1.001/I. VC-3 compression rates supported with thismapping are limited to the payload capacity of the 270 Mbps SDTI and are listed inTable 4.

For the transmission of compressed picture data coded at source picture rates of 25/P, 50/P and 50/I, theSDTI operates at a frame rate of 25Hz. For the transmission of compressed picture data coded at sourcepicture rates of 30/1.001/P, 60/1.001/P, and 60/1.001/I, the SDTI operates at a frame rate of 30/1.001 Hz.
