Video Core Next
Video Core Next is AMD's brand for its dedicated video encoding and decoding hardware core. It is a family of hardware accelerator designs for encoding and decoding video, and is built into AMD's GPUs and APUs since AMD Raven Ridge, released January 2018. Background Video Core Next is AMD's successor to both the Unified Video Decoder and Video Coding Engine designs, which are hardware accelerators for video decoding and encoding, respectively. It can be used to decode, encode and transcode ("sync") video streams, for example, a DVD or Blu-ray Disc to a format appropriate to, for example, a smartphone. Unlike video encoding on a CPU or a general-purpose GPU, Video Core Next is a dedicated hardware core on the processor die. This application-specific integrated circuit (ASIC) allows for more power-efficient video processing. Support Video Core Next supports: MPEG-2 Decode, MPEG-4 Decode, VC-1 Decode, H.264/MPEG-4 AVC Encode/Decode, HEVC Encode/Decode, and VP9 Decode. VCN 2.0 is ...

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 ...

VC-1
SMPTE 421, informally known as VC-1, is a video coding format. Most of it was initially developed as Microsoft's proprietary video format Windows Media Video 9 in 2003. With some enhancements including the development of a new Advanced Profile, it was officially approved as a SMPTE standard on April 3, 2006. It was primarily marketed as a lower-complexity competitor to the H.264/MPEG-4 AVC standard. After its development, several companies other than Microsoft asserted that they held patents that applied to the technology, including Panasonic, LG Electronics and Samsung Electronics. VC-1 is supported in the now-deprecated Microsoft Silverlight, the briefly-offered HD DVD disc format, and the Blu-ray Disc format. Format VC-1 is an evolution of the conventional block-based motion-compensated hybrid video coding design also found in H.261, MPEG-1 Part 2, H.262/MPEG-2 Part 2, H.263, and MPEG-4 Part 2. It was widely characterized as an alternative to the ITU-T and MPEG video cod ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Nvidia NVDEC
Nvidia NVDEC (formerly known as NVCUVID) is a feature in its graphics cards that performs video decoding, offloading this compute-intensive task from the CPU. It is accompanied by NVENC for video ''encoding'' in Nvidia's Video Codec SDK. Technology NVDEC can offload video decoding to full fixed-function decoding hardware (Nvidia PureVideo), or (partially) decode via CUDA software running on the GPU, if fixed-function hardware is not available. Depending on the GPU architecture, the following codecs are supported: * MPEG-2 * VC-1 * H.264 (AVC) * H.265 (HEVC) * VP8 * VP9 * AV1 Versions NVCUVID was originally distributed as part of the Nvidia CUDA Toolkit. Later, it was renamed to NVDEC and moved to the Nvidia Video Codec SDK. Operating system support NVDEC is available for Windows and Linux operating systems. As NVDEC is a proprietary API (as opposed to the open-source VDPAU API), it is only supported by the proprietary Nvidia driver on Linux. Application and library s ...

Nvidia NVENC
Nvidia NVENC (short for Nvidia Encoder) is a feature in Nvidia graphics cards that performs video encoding, offloading this compute-intensive task from the CPU to a dedicated part of the GPU. It was introduced with the Kepler-based GeForce 600 series in March 2012. The encoder is supported in many livestreaming and recording programs, such as vMix, Wirecast, Open Broadcaster Software (OBS) and Bandicam, as well as video editing apps, such as Adobe Premiere Pro or DaVinci Resolve. It also works with Share game capture, which is included in Nvidia's GeForce Experience software. Consumer targeted GeForce graphics cards officially support no more than 3 simultaneously encoding video streams, regardless of the count of the cards installed, but this restriction can be circumvented on Linux and Windows systems by applying an unofficial patch to the drivers. Doing so also unlocks ''NVIDIA Frame Buffer Capture (NVFBC)'', a fast desktop capture API that uses the capabilities of the GP ...

High-Definition Video Processor
Nvidia's High-Definition Digital Processing (HDVP) is an HDTV accelerator on the Geforce 2 GTS. It has a downscalar that supports 1080i and 720p to SDTV resolution. In combination with a tuner chip it creates an accelerated HDTV viewing system that supports time-shifted recording. The Geforce 2 GTS also includes second generation motion compensation, improved from the motion compensation on the Geforce 256. It does not seem to include IDCT acceleration. The HDVP also includes de-interlace acceleration including bob, weave, temporal filter, and advanced de-interlacing. Finally, HDVP supports subpicture compositing, and color enhancements including brightness, hue, contrast, and saturation. nVidia's HDVP would endure through the GeForce 4 Series in the Geforce 4 Ti NV25.http://www.activewin.com/reviews/hardware/graphics/nvidia/gf4ti4600/gf3.shtml See also * GeForce 256's Motion Compensation * Video Processing Engine * PureVideo * DirectX Video Acceleration (DxVA) API for Mic ...

Geforce 256
The GeForce 256 is the original release in Nvidia's "GeForce" product-line. Announced on August 31, 1999 and released on October 11, 1999, the GeForce 256 improves on its predecessor (RIVA TNT2) by increasing the number of fixed pixel pipelines, offloading host geometry calculations to a hardware transform and lighting (T&L) engine, and adding hardware motion compensation for MPEG-2 video. It offered a notably large leap in 3D PC gaming performance and was the first fully Direct3D 7-compliant 3D accelerator. The chip was manufactured by TSMC using its 220 nm CMOS process. There are two versions of the GeForce 256 the SDR version released in October 1999 and the DDR version released in mid-December 1999 each with a different type of SDRAM memory. The SDR version uses SDR SDRAM memory from Samsung Electronics, while the later DDR version uses DDR SDRAM memory from Hyundai Electronics (now SK Hynix).

Nvidia PureVideo
PureVideo is Nvidia's hardware SIP core that performs video decoding. PureVideo is integrated into some of the Nvidia GPUs, and it supports hardware decoding of multiple video codec standards: MPEG-2, VC-1, H.264, HEVC, and AV1. PureVideo occupies a considerable amount of a GPU's die area and should not be confused with Nvidia NVENC. In addition to video decoding on chip, PureVideo offers features such as edge enhancement, noise reduction, deinterlacing, dynamic contrast enhancement and color enhancement. Operating system support The PureVideo SIP core needs to be supported by the device driver, which provides one or more interfaces such as NVDEC, VDPAU, VAAPI or DXVA. One of these interfaces is then used by end-user software, for example VLC media player or GStreamer, to access the PureVideo hardware and make use of it. Nvidia's proprietary device driver is available for multiple operating systems and support for PureVideo has been added to it. Additionally, a free device d ...

JPEG
JPEG ( ) is a commonly used method of lossy compression for digital images, particularly for those images produced by digital photography. The degree of compression can be adjusted, allowing a selectable tradeoff between storage size and image quality. JPEG typically achieves 10:1 compression with little perceptible loss in image quality. Since its introduction in 1992, JPEG has been the most widely used image compression standard in the world, and the most widely used digital image format, with several billion JPEG images produced every day as of 2015. The term "JPEG" is an acronym for the Joint Photographic Experts Group, which created the standard in 1992. JPEG was largely responsible for the proliferation of digital images and digital photos across the Internet, and later social media. JPEG compression is used in a number of image file formats. JPEG/Exif is the most common image format used by digital cameras and other photographic image capture devices; along with JPEG ...

Windows Media Video
Windows Media Video (WMV) is a series of video codecs and their corresponding video coding formats developed by Microsoft. It is part of the Windows Media framework. WMV consists of three distinct codecs: The original video compression technology known as ''WMV'', was originally designed for Internet streaming applications, as a competitor to RealVideo. The other compression technologies, ''WMV Screen'' and ''WMV Image'', cater for specialized content. After standardization by the Society of Motion Picture and Television Engineers (SMPTE), WMV version 9 was adapted for physical-delivery formats such as HD DVD and Blu-ray Disc and became known as VC-1. Microsoft also developed a digital container format called Advanced Systems Format to store video encoded by Windows Media Video. History In 2003, Microsoft drafted a video compression specification based on its WMV 9 format and submitted it to SMPTE for standardization. The standard was officially approved in March 2006 as SMPTE ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
