| Coding-independent code points for video signal type identification |
 |
Recommendation ITU-T H.273 defines various code points and fields that establish properties of a video (or still image) representation and are independent of the compression encoding and bit rate. These properties may describe the appropriate interpretation of decoded data or may, similarly, describe the characteristics of such a signal before the signals are compressed by an encoder that is suitable for compressing such an input signal. The text was developed as a twin text Recommendation corresponding to the video code points in ISO/IEC 23091-2 (formerly ISO/IEC 23001-8) in collaboration with ISO/IEC JTC 1/SC 29. It is published as a technically aligned twin text by both organizations (ITU-T and ISO/IEC). |
