SMPTE ST 2047-4 PDF

This standard defines the method of mapping VC-2 data onto an SDTV SDI link operating at 270Mbps, based upon the data structures defined in SMPTE ST 259 and ITU-R BT 656 to transport the compressed HD video formats listed in Table 1. The compressed HD video formats supported by this standard are those supported by the low delay profile of VC-2 at level 65. These formats are 1080I at 50 or 60/1.001 fields/s (i.e., SMPTE ST 274 systems 5 and 6), and 720P at 50 or 60/1.001 frames/s (i.e., SMPTE ST 296 systems 2 and 3). Additionally VC-2 level 65 supports the compression of SMPTE ST 274 systems 5 and 6 in which the horizontal sample rate has been reduced to 1440 pixels.

The SDTV SDI link defined herein supports the carriage of embedded audio, ancillary data and payload identification.

A signal coded in accordance with this standard incorporates a noisy but recognizable picture that can be viewed using a standard SMPTE ST 259 / ITU-R BT 656 video monitor.
