This standard specifies extensions to the VC-5 Elementary Bitstream defined in SMPTE ST 2073-1 for representing R'G'B'(A) images, Y'C'1C'2(A) images without color difference component sub-sampling, and Color Filter Array (CFA) images including Bayer image formats. This standard specifies the default color space for R'G'B' and Y'C'1C'2 color values.

This standard extends SMPTE ST 2073-1 by adding new parameters and chunk elements:

The ImageFormat parameter specifies the type of image: R'G'B'(A), Y'C'1C'2(A), CFA, or Bayer,
The PatternWidth, PatternHeight, and ComponentsPerSample parameters specify the structure of CFA images, including Bayer images,
The MaxBitsPerComponent parameter specifies an upper bound on the number of bits needed to represent all values in the component arrays present in the bitstream,
The VendorSpecificData chunk element allows private data to be embedded in a VC-5 bitstream,
The InverseTransform, InverseTransform16, and InversePermutation chunk elements specify how to transform and reorder decoded component arrays into the same color space and order as originally presented to the encoder,
The UniqueImageIdentifier chunk element specifies the image sequence and position within the sequence of an image represented by a VC-5 bitstream.

This standard extends SMPTE ST 2073-1 by defining three stages for transforming decoded component arrays into images: inverse component transform, inverse component permutation, and image repacking process.

This standard extends SMPTE ST 2073-1 to specify levels of performance for decoder implementations.
