2.4 Video Acceleration Features
UVD video decoder acceleration technology:
• Dedicated Unified Video Decoder (UVD) for HEVC (H.265), H.264, VC-1/ WM9,
MPEG-4 part 2, MPEG-2, and MVC decode:
• HEVC Decode:
∘ Implementation is based on the ITU-T H.265 v.1 specification
∘ Supports Main/Main 10 profiles, Level 5.1
∘ Supports up to 4096 × 2160 resolution at 60 fps
∘ Up to a bit rate of 160 Mbps
∘ Supports HDR-10 video playback
• H.264 Decode:
∘ Implementation is based on the ISO/IEC 14496-10 specification
∘ Supports up to High profile, Level 5.2—Support for Constrained
Baseline profile (no FMO, no ASO) only
∘ Supports up to 4096 × 2160 resolution at 60 fps
∘ Up to a bit rate of 160 Mbps
∘ Supports MVC decode for Blu-ray 3D content
∘ Supports up to 18 HD streams (1080p) at 30 fps each
• VC-1 Decode:
∘ Implementation based on the SMPTE 421M specification
∘ Supports up to AP @ L3
∘ Supports up to 1080p @ 60 fps
∘ Maximum bit rate of 40 Mbps
• MPEG-4 Part 2 Decode:
∘ Supports up to ASP @ L5, high-definition profiles
∘ Sprite, GMC (global motion compensation), and RVLC (reversible
variable length coding) are not supported
• MPEG-2 Decode:
∘ Implementation based on the ISO 13818-2 specification
∘ Supports up to MP @ HL
• MJPEG Decode:
∘ Implementation is based on the ISO/IEC 10918-1 specification
∘ Supports Baseline (DCT based, interleaved only)
∘ Supports up to 8K × 8K resolution (TBD)
∘ JFIF input format
