High Efficiency Video Coding (HEVC) – video standard that supports 4K & 8K UHDTV and resolutions up to 8192 × 4320 Rec. 2020 – ITU-R recommendation for UHDTV, defining formats with resolutions of 4K ( 3840 × 2160 ) and 8K ( 7680 × 4320 )
An alpha channel may be present to represent transparency, so that alpha blending overlay capability is enabled. Compressed-domain image modification In JPEG XR, full decoding of the image is unnecessary for converting an image from a lossless to lossy encoding, reducing the fidelity of a lossy encoding, or reducing the encoded image resolution.
8K display resolution is the successor to 4K resolution. TV manufacturers pushed to make 4K a new standard by 2017. At CES 2012, the first prototype 8K TVs were unveiled by Japanese electronics corporation Sharp. [2] The feasibility of a fast transition to this new standard is questionable in view of the absence of broadcasting resources.
The standard will encode videos under the High Efficiency Video Coding standard. [31] 4K Blu-ray Discs support both a higher color precision by increasing the color depth to 10 bits per color, and a greater color gamut by using the Rec. 2020 color space. [31] The 4K Blu-ray specification allows for three disc sizes: 50 gb, 66 gb and 100 gb.
ADK was founded in July 1980 in Ageo, Saitama, Japan. [1] At the time, it was known as Alpha Denshi or Alpha for short. Originally a producer of audio and telecommunications equipment, Alpha first ventured into video games in 1980 with two arcade titles: Dorachan (ドラちゃん) by Craul Denshi and Tehkan's Shogi (将棋), a basic Japanese chess game.
In 2017 Google's data compression research team in Zurich published the PIK format, the prototype for the frequency transform coding mode. In 2018, the Joint Photographic Experts Group (JTC1 / SC29 / WG1) published a call for proposals for JPEG XL, its next-generation image coding standard. [9] The proposals were submitted by September 2018.
AV1 Image File Format (AVIF) is an open, royalty-free image file format specification for storing images or image sequences compressed with AV1 in the HEIF container format. [1] [2] It competes with HEIC, which uses the same container format built upon ISOBMFF, but HEVC for compression.
Animated Portable Network Graphics (APNG) is a file format which extends the Portable Network Graphics (PNG) specification to permit animated images that work similarly to animated GIF files, while supporting 24 or 48-bit images and full alpha transparency not available for GIFs.
