Coding efficiency is the ability to encode video at the lowest possible bit rate while maintaining a certain level of video quality. There are two standard ways to measure the coding efficiency of a video coding standard, which are to use an objective metric, such as peak signal-to-noise ratio (PSNR), or to use subjective assessment of video ...
The HEVC standard defines thirteen levels. [1] [2] A level is a set of constraints for a bitstream.[1] [2] For levels below level 4 only the Main tier is allowed.[1] [2] A decoder that conforms to a given tier/level is required to be capable of decoding all bitstreams that are encoded for that tier/level and for all lower tiers/levels.
The HEVC Encoder is a software implementation on Intel x86 based platforms, capable of High Definition (HD) broadcast quality video encoding. The Decoder software available on ARM CortexTM-A9 and CortexTM-A15 based SoCs allows a wide range of existing Consumer Electronics (CE) devices such as Smartphones, Tablets, Smart TVs and Set-Top Boxes to ...
The quality the codec can achieve is heavily based on the compression format the codec uses. A codec is not a format, and there may be multiple codecs that implement the same compression specification – for example, MPEG-1 codecs typically do not achieve quality/size ratio comparable to codecs that implement the more modern H.264 specification.
High Efficiency Video Coding (HEVC), a.k.a. H.265 and MPEG-H Part 2 is a successor to H.264/MPEG-4 AVC developed by the same organizations, while earlier standards are still in common use. H.264 is perhaps best known as being the most commonly used video encoding format on Blu-ray Discs.
A video coding format [a] (or sometimes video compression format) is a content representation format of digital video content, such as in a data file or bitstream. It typically uses a standardized video compression algorithm, most commonly based on discrete cosine transform (DCT) coding and motion compensation .
The High-Efficiency Image File Format (HEIF) is a container for images and videos that improves compression while improving image quality and adding new benefits over older formats (JPEG, PNG, and ...
Coding tree unit (CTU) is the basic processing unit of the High Efficiency Video Coding (HEVC) video standard and conceptually corresponds in structure to macroblock units that were used in several previous video standards. [1] [2] CTU is also referred to as largest coding unit (LCU). [3]
