Unified Video Decoder Unified Video Decoder (UVD), previously called Universal Video Decoder, is the name given to AMD's dedicated video decoding ASIC. There are multiple versions implementing a multitude of video codecs, such as H.264 and VC-1. UVD was introduced with the Radeon HD 2000 Series and is integrated into some of the AMD GPUs and APUs. UVD occupies a considerable amount of the die surface〔(【引用サイトリンク】title=AMD A-Series APU block diagram )〕 and is not to be confused with AMD's Video Coding Engine (VCE). ==Overview== The UVD is based on an ATI Xilleon video processor, which is incorporated onto the same die as the GPU and is part of the ATI Avivo HD for hardware video decoding, along with the Advanced Video Processor (AVP). UVD, as stated by AMD, handles decoding of H.264/AVC, and VC-1 video codecs entirely in hardware. The UVD technology is based on the Cadence Tensilica Xtensa processor, which was originally licensed by ATI Technologies Inc. in 2004.
