This document specifies the mapping of the VC-3 type compressed picture data stream into the SMPTE 305M SDTI payload area. The VC-3 type compressed picture data stream mapping is defined for source coded 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 this mapping 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, the SDTI operates at a frame rate of 25Hz. For the transmission of compressed picture data coded at source picture 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.
