2. Comparison of video codecs - Wikipedia

   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 ...

3. High Efficiency Video Coding - Wikipedia

   en.wikipedia.org/wiki/High_Efficiency_Video_Coding

   HEVC / H.265 / MPEG-H Part 2. 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 ...

4. Image compression - Wikipedia

   en.wikipedia.org/wiki/Image_compression

   Image compression. Image compression is a type of data compression applied to digital images, to reduce their cost for storage or transmission. Algorithms may take advantage of visual perception and the statistical properties of image data to provide superior results compared with generic data compression methods which are used for other ...

5. Video compression picture types - Wikipedia

   en.wikipedia.org/wiki/Video_compression_picture...

   A sequence of video frames, consisting of two keyframes (I), one forward-predicted frame (P) and one bi-directionally predicted frame (B). Three types of pictures (or frames) are used in video compression: I, P, and B frames. An I‑frame (Intra-coded picture) is a complete image, like a JPG or BMP image file. A P‑frame (Predicted picture ...

6. Context-adaptive binary arithmetic coding - Wikipedia

   en.wikipedia.org/wiki/Context-adaptive_binary...

   Context-adaptive binary arithmetic coding (CABAC) is a form of entropy encoding used in the H.264/MPEG-4 AVC [1][2] and High Efficiency Video Coding (HEVC) standards. It is a lossless compression technique, although the video coding standards in which it is used are typically for lossy compression applications.

7. H.261 - Wikipedia

   en.wikipedia.org/wiki/H.261

   H.261 is an ITU-T video compression standard, first ratified in November 1988. [1] [2] It is the first member of the H.26x family of video coding standards in the domain of the ITU-T Study Group 16 Video Coding Experts Group (VCEG, then Specialists Group on Coding for Visual Telephony).
