  2. Nvidia PureVideo - Wikipedia

    en.wikipedia.org/wiki/Nvidia_PureVideo

    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 ...

  3. Nvidia NVDEC - Wikipedia

    en.wikipedia.org/wiki/Nvidia_NVDEC

    Nvidia NVDEC. Nvidia NVDEC (formerly known as NVCUVID [1]) is a feature in its graphics cards that performs video decoding, offloading this compute-intensive task from the CPU. [2] NVDEC is a successor of PureVideo and is available in Kepler and later NVIDIA GPUs. It is accompanied by NVENC for video encoding in Nvidia's Video Codec SDK.

    en.wikipedia.org/wiki/Comparison_of_video_codecs

    Comparison of video codecs. Α video codec is software or a device that provides encoding and decoding for digital video, and which may or may not include the use of video compression and/or decompression. Most codecs are typically implementations of video coding formats . The compression may employ lossy data compression, so that quality ...

    VideoLAN dav1d – An AV1 decoder for decoding videos with AV1 codec; Xiph.Org rav1e – An AV1 encoder written in Rust; Google libgav1 – An AV1 decoder by Google; xvc – An open source video codec, aiming to compete with h.265 and AV1. The reference implementation is released under the LGPL 2.1 and currently available in version 2.0 (as of ...

  6. Video codec - Wikipedia

    en.wikipedia.org/wiki/Video_codec

    A video codec is software or hardware that compresses and decompresses digital video. In the context of video compression, codec is a portmanteau of encoder and decoder, while a device that only compresses is typically called an encoder, and one that only decompresses is a decoder . The compressed data format usually conforms to a standard ...

  7. Video decoder - Wikipedia

    en.wikipedia.org/wiki/Video_decoder

    A video decoder is an electronic circuit, often contained within a single integrated circuit chip, that converts base-band analog video signals to digital video. [ 1] Video decoders commonly allow programmable control over video characteristics such as hue, contrast, and saturation. A video decoder performs the inverse function of a video ...

  8. High Efficiency Video Coding - Wikipedia

    en.wikipedia.org/wiki/High_Efficiency_Video_Coding

    High Efficiency Video Coding ( HEVC ), also known as H.265 and MPEG-H Part 2, is a video compression standard designed as part of the MPEG-H project as a successor to the widely used Advanced Video Coding (AVC, H.264, or MPEG-4 Part 10). In comparison to AVC, HEVC offers from 25% to 50% better data compression at the same level of video quality ...

  9. VP9 - Wikipedia

    en.wikipedia.org/wiki/VP9

    VP9 is an open and royalty-free [ 1] video coding format developed by Google . VP9 is the successor to VP8 and competes mainly with MPEG's High Efficiency Video Coding (HEVC/H.265). At first, VP9 was mainly used on Google's video platform YouTube. [ 2][ 3] The emergence of the Alliance for Open Media, and its support for the ongoing development ...
