Information technology – Generic coding of moving pictures and associated audio information: Video |
|
This Recommendation | International Standard specifies coded representation of video data and the decoding process required to reconstruct pictures. It provides a generic video coding scheme which serves a wide range of applications, bit rates, picture resolutions and qualities. Its basic coding algorithm is a hybrid of motion compensated prediction and DCT. Pictures to be coded can be either interlaced or progressive. Necessary algorithmic elements are integrated into a single syntax, and a limited number of subsets are defined in terms of Profile (functionalities) and Level (parameters) to facilitate practical use of this generic video coding standard.This second edition of this Recommendation | International Standard consists of ITU-T Rec. H.262 (1995) | ISO/IEC 13818-2:1996, subsequently altered by two corrigenda and six amendments:1. A first corrigendum adding a slice picture identifier, allowing an application to define default colour description parameters, removing a prohibition of field-structured DCT coding in progressive frames, clarifying ambiguity on restricted range of reconstructed motion vectors, clarifying ambiguity of VBV at boundaries of sequences, and making various minor corrections.2. A second corrigendum altering the inverse discrete cosine transform requirements, altering temporal_reference for low delay, and making various minor corrections.3. A first amendment providing a method of obtaining and registering copyright identifiers.4. A second amendment defining a 4:2:2 profile.5. A third amendment adding a camera parameters extension and a multi-view profile.6. A fourth amendment adding an ITU-T extension.7. A fifth amendment adding a high level to the 4:2:2 profile.8. A sixth amendment reducing the upper bound for the number of lines per frame in the high level of all profiles from 1152 to 1088.
