What the actual ****?

2094 is a new standard suite of documents which is a work in progress, the overall project being about 50% complete. Specifically, ST 2094-10 Application #1, which just fairly recently was posted for pre-FCD ballot review and discussed by the compression (HEVC) engineers as to exactly how to implement it as a new SEI message in order to carry der metadata.

In a nutshell, SMPTE 2094 is being developed to provide some display adaptation metadata. The nominal purpose of SMPTE 2094 is to enable adaptation of a video signal to a smaller color volume (e.g., lower dynamic range).

You desire a greater color volume than that of BT. 2020, then….




or, subtracting out all the overriding triangles seen above ^…..
