AVC/H.264
• High profile, all levels up to and including 4.1
• Up to 40 Mb/sec. code stream bit rate
• Adaptive block size, quantization matrixes
The Advanced Video Decoder module decodes any bitstream coded with any combination of tools allowed under the Main
Profile as defined in the ISO standard 14496-10, (MPEG-4 Part 10). This includes any streams encoded by a baseline
encoder with the appropriate compatibility flag set for Main Profile operation.
The AVD module decodes bitstreams conforming to the restrictions set by Level 4.1 as specified in Annex A of ISO/IEC
Recommendation 14496-10 with the following restriction:
• Maximum encoded bit rate is 40 megabits per second.
This level supports pictures in the 1920x1088 interlaced format used by HDTV systems at a rate of 60 fields per-second.
VC-1
The AVD module supports VC-1 elementary streams in the following profiles and levels:
• Advanced profile levels AP@L0, AP@L1, AP@L2, AP@L3
• Main profile levels MP@LL, MP@ML, MP@HL
• Simple profile levels SP@LL, SP@ML
VC-1 decoding has the following restriction:
• Maximum encoded bit rate is 45 megabits per-second.
MPEG-2
• Main profile @ high level, main level
The AVD module supports MPEG-2 elementary streams encoded under the main profile at high level, as defined in ISO/IEC
Recommendation 13818-2, with the following restrictions:
• Maximum encoded bit rate: 125 megabits per-second.
• Internal data format: 4:2:0 format only.
MPEG-4 Part2
• MP4 SP up to HD with the exception of:
- reversible VLC codes
- data partitioning
• MP4 ASP up to HD with the exception of:
- global motion compensation
- 1/4-pel motion compensation
DivX
• Version 3.11, 4.11, 5.X, 6.X
- Progressive and Interlaced
- Up to HD support
