ISO/IEC provides the following elements related to the encoded representation of visual information: Specification of video coding tools, object. ISO/IEC Information technology — Coding of audio-visual objects — Part 2: Visual. This standard has been revised by ISO/IEC Coding of audio, picture, multimedia and hypermedia information. ICS: Coding of audio, video, multimedia and hypermedia information.

ISO/IEC – Information technology — Coding of audio-visual objects — Part 2: Visual
Video based on H. The most commonly deployed profiles are Advanced Simple and Simple, which is a subset of Advanced Simple. High Efficiency Image File Format. Therefore, implementations for a particular profile such as DivX or Nero Digital which are implementations of Advanced Simple Profile and Xvid that implements both profiles are all technically identical on the decoder side.
Some implementations omit support for this feature, because it has a significantly harmful effect on speed and it is not always beneficial for quality. High Efficiency Video Coding Part 3: Most of the video compression schemes standardize the bitstream and thus the decoder leaving the encoder design to the individual implementations.

Archived from the original on Scene description Part From Wikipedia, the free encyclopedia. Simple Profile is mostly aimed for use in situations where low bit rate and low resolution are mandated by other conditions of the applications, like network 14496-22, device size etc.

Multimedia compression and container formats.

When used, ASP’s global motion compensation has a large unfavorable impact on speed and adds considerable complexity to the implementation.
Arms; Carl Fleischhauer; Kate Murray. Advanced Simple Profile ‘s notable technical features relative to the Simple Profile, which is roughly similar to H.

Most encoders do not support it either, and some experts say that it does not ordinarily provide any benefit in compression. The global motion compensation feature is not actually supported in most implementations although the standard officially requires decoders to support it.
