What is H264 high profile?

H.264 High Profile is the most efficient and powerful profile in the H.264 family, and is the primary profile for broadcast and disc storage, particularly for HDTV and Bluray disc storage formats. It can achieve a compression ratio of about 2000:1. The High Profile also uses an adaptive transform that can select between 4×4 or 8×8-pixel blocks.

What is Main profile and high profile?

Main Profile (MP): Originally intended as the mainstream consumer profile for broadcast and storage applications, the importance of this profile faded when the High profile was developed for those applications.

What is the purpose of h264/avc?

The intent of the H.264/AVC project was to create a standard capable of providing good video quality at substantially lower bit rates than previous standards (i.e., half or less the bit rate of MPEG-2, H.263, or MPEG-4 Part 2 ), without increasing the complexity of design so much that it would be impractical or excessively expensive to implement.

What is H264 used for on TV?

It is used for SD digital TV broadcasts that use the MPEG-4 format, but not for HD broadcasts. H.264 High Profile is the most efficient and powerful profile in the H.264 family, and is the primary profile for broadcast and disc storage, particularly for HDTV and Bluray disc storage formats.

What is the hi422p video profile?

High 4:2:2 Profile (Hi422P): Primarily targeting professional applications that use interlaced video, this profile builds on top of the High 10 Profile—adding support for the 4:2:2 chroma subsampling format while using up to 10 bits per sample of decoded picture precision.

What is a hi444pp profile?

High 4:4:4 Predictive Profile (Hi444PP): This profile builds on top of the High 4:2:2 Profile—supporting up to 4:4:4 chroma sampling, up to 14 bits per sample, and additionally supporting efficient lossless region coding and the coding of each picture as three separate color planes.

What is the difference between high 4-4-4 Intra profile and CAVLC 4-3-4 profile?

High 4:4:4 Intra Profile: The High 4:4:4 Profile constrained to all-Intra use. CAVLC 4:4:4 Intra Profile: The High 4:4:4 Profile constrained to all-Intra use and to CAVLC entropy coding (i.e., not supporting CABAC).
