SMPTE ST 2019-1 – VC-3 Picture Compression and Data Stream Format

This standard specifies the compressed data format and decoding process for VC-3 compressed video data. VC-3 supports video up to 16384 x 16384 raster resolutions as YCBCR(A) (4:4:4(:4), 4:2:2(:4), 4:2:0(:4)) at 8-, 10- and 12-bit or as RGB(A) at 10- or 12-bit sampling depth.

VC-3 is an intra-frame compression format, independent of any predefined frame rate, which supports both constant (CBR) and variable (VBR) bitrate operations. The compression parameters are described by the contents of a header data region and attributes associated with a Compression ID described within this standard. The standard does not specify the encoding process nor does it define video frame rates although examples are used in this document.
