    "abstract": "The VC-2 video compression standard is an intra-frame video compression system defined through the VC-2 stream syntax, entropy coding, a coefficient unpacking process and a picture decoding process. The decoder operations are defined by means of a mixture of pseudo-code and mathematical operations. — This recommended practice defines the materials, procedures, and criteria for verifying conformance of SMPTE VC-2 video decoders. The documents that form this specification include this document, a register of test streams, a sample VC-2 stream generator and a reference decoder. — The reference decoder and the sample stream generator are both software written in the C++ programming language and capable of being compiled to executable code on a variety of computer platforms. The reference decoder can be used to verify conformance of VC-2 decoder implementations against a register of test streams, and the conformance of arbitrary streams to the VC-2 specification. — This conformance practice defines both the format for the register of test streams and the lists of test streams.",
