The global motion compensation feature is not actually supported in most implementations although the standard officially requires decoders to support it.

MPEG-4 Part 2

Why, What, How and When? Unified Speech and Audio Coding. Multimedia compression and container formats.

From Wikipedia, the free encyclopedia. Archived from the original on Kso Efficiency Image File Format. Most of the video compression schemes standardize the bitstream and thus the decoder leaving the encoder design to the individual implementations.

Some implementations omit support for this feature, because it has a significantly harmful effect on speed and it is not always beneficial for quality. Most encoders do not support it either, and some experts say that it does not ordinarily provide any benefit in compression. Advanced Simple Profile ‘s notable technical features relative to the Simple Profile, which is roughly similar to H.

Examples are mobile phonessome low end video conferencing systems, electronic surveillance systems etc. High Efficiency Video Coding Part 3: Open Font Format Part 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 bandwidth, device size etc. MP4 file format Part Streaming text format Part This page was last edited on 30 Novemberat Video based on H.

When used, ASP’s global motion compensation has a large unfavorable impact on speed and adds considerable complexity to the implementation.


To address various applications ranging from low-quality, low-resolution surveillance cameras to high definition TV broadcasting and DVDs, many video standards group features into profiles and levels.

I was involved in many digital media projects that wouldn’t even touch MPEG-4 in the late s to early s because there was going to be a ‘content fee’ that hadn’t been fully defined yet.

Therefore, implementations for a particular profile such as DivX or Nero Digital which are implementations of Advanced Simple Profile and Xvid iiso implements both profiles are all technically identical on the decoder side. Sustainability of Digital Formats.
