UVD
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 AMD's GPUs and APUs. UVD occupies a considerable amount of the die surface at the time of its introduction and is not to be confused with AMD's Video Coding Engine (VCE). As of AMD Raven Ridge (released January 2018), UVD and VCE were succeeded by Video Core Next (VCN). 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 license ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Video Coding Engine
Video Code Engine (VCE, was earlier referred to as Video Coding Engine, Video Compression Engine or Video Codec Engine in official AMD documentation) is AMD's video encoding application-specific integrated circuit implementing the video codec H.264/MPEG-4 AVC. Since 2012 it was integrated into all of their GPUs and APUs except Oland. VCE was introduced with the Radeon HD 7000 Series on 22 December 2011. VCE occupies a considerable amount of the die surface at the time of its introduction and is not to be confused with AMD's Unified Video Decoder (UVD). As of AMD Raven Ridge (released January 2018), UVD and VCE were succeeded by Video Core Next (VCN). Overview The handling of video data involves computation of data compression algorithms and possibly of video processing algorithms. As the template compression methods shows, lossy video compression algorithms involve the steps: motion estimation (ME), discrete cosine transform (DCT), and entropy encoding (EC). AMD Video Cod ...

Radeon HD 2000 Series
The graphics processing unit (GPU) codenamed Radeon R600 is the foundation of the Radeon HD 2000 series and the FireGL 2007 series video cards developed by ATI Technologies. The HD 2000 cards competed with nVidia's GeForce 8 series. Architecture This article is about all products under the brand "Radeon HD 2000 Series". They all contain a GPU which implements TeraScale 1, ATI's first Unified shader model microarchitecture for PCs. Video acceleration The Unified Video Decoder (UVD) SIP core is on-die in the HD 2400 and the HD 2600. The HD 2900 GPU dies do not have a UVD core, as its stream processors were powerful enough to handle most of the steps of video acceleration in its stead except for entropy decoding and bitstream processing which are left for the CPU to perform. Other features HDTV encoding support is implemented via the integrated AMD Xilleon encoder; the companion ''Rage Theater'' chip used on the Radeon X1000 series was replaced with the digital ''Theater 200' ...

AVIVO HD
ATI Avivo is a set of hardware and low level software features present on the ATI Radeon R520 family of GPUs and all later ATI Radeon products. ATI Avivo was designed to offload video decoding, encoding, and post-processing from a computer's CPU to a compatible GPU. ATI Avivo compatible GPUs have lower CPU usage when a player and decoder software that support ATI Avivo is used. ATI Avivo has been long superseded by Unified Video Decoder (UVD) and Video Coding Engine (VCE). Background The GPU wars between ATI and NVIDIA have resulted in GPUs with ever-increasing processing power since early 2000s. To parallel this increase in speed and power, both GPU makers needed to increase video quality as well, in 3D graphics applications the focus in increasing quality has mainly fallen on anti-aliasing and anisotropic filtering. However it has dawned upon both companies that video quality on the PC would need improvement as well and the current APIs provided by both companies have not se ...

Graphics Processing Unit
A graphics processing unit (GPU) is a specialized electronic circuit designed to manipulate and alter memory to accelerate the creation of images in a frame buffer intended for output to a display device. GPUs are used in embedded systems, mobile phones, personal computers, workstations, and game consoles. Modern GPUs are efficient at manipulating computer graphics and image processing. Their parallel structure makes them more efficient than general-purpose central processing units (CPUs) for algorithms that process large blocks of data in parallel. In a personal computer, a GPU can be present on a video card or embedded on the motherboard. In some CPUs, they are embedded on the CPU die. In the 1970s, the term "GPU" originally stood for ''graphics processor unit'' and described a programmable processing unit independently working from the CPU and responsible for graphics manipulation and output. Later, in 1994, Sony used the term (now standing for ''graphics processing unit'' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Advanced Micro Devices
Advanced Micro Devices, Inc. (AMD) is an American multinational semiconductor company based in Santa Clara, California, that develops computer processors and related technologies for business and consumer markets. While it initially manufactured its own processors, the company later outsourced its manufacturing, a practice known as going fabless, after GlobalFoundries was spun off in 2009. AMD's main products include microprocessors, motherboard chipsets, embedded processors, graphics processors, and FPGAs for servers, workstations, personal computers, and embedded system applications. History First twelve years Advanced Micro Devices was formally incorporated by Jerry Sanders, along with seven of his colleagues from Fairchild Semiconductor, on May 1, 1969. Sanders, an electrical engineer who was the director of marketing at Fairchild, had, like many Fairchild executives, grown frustrated with the increasing lack of support, opportunity, and flexibility within th ...

Deblocking Filter (video)
A deblocking filter is a video filter applied to decoded compressed video to improve visual quality and prediction performance by smoothing the sharp edges which can form between macroblocks when block coding techniques are used. The filter aims to improve the appearance of decoded pictures. It is a part of the specification for both the SMPTE VC-1 codec and the ITU H.264 (ISO MPEG-4 AVC) codec. H.264 deblocking filter In contrast with older MPEG- 1/ 2/ 4 standards, the H.264 deblocking filter is not an optional additional feature in the decoder. It is a feature on both the decoding path and on the encoding path, so that the in-loop effects of the filter are taken into account in reference macroblocks used for prediction. When a stream is encoded, the filter strength can be selected, or the filter can be switched off entirely. Otherwise, the filter strength is determined by coding modes of adjacent blocks, quantization step size, and the steepness of the luminance gradient betw ...
