The H.266 codec is said to bring an improved compression algorithm. This week saw the announcement of the H.266 codec, also known as VVC, which stands for Versatile Video Coding. Raspberry Pi fans will be happy to hear that the Raspberry Pi 4 B has HEVC decoding built into hardware, though earlier models do not. Here are some SoCs known to support HEVC: Smartphones and other media playback devices can also playback HEVC video with the right hardware. If you’re an Apple user, you need macOS High Sierra or newer. You also need an Intel 6th Generation Skylake or newer / AMD 6th generation Carizzo or newer CPU, OR an Nvidia GeForce GTX 950 / 950 graphics card or newer / AMD Radeon R9 Fury / Fury X / Nano or newer.

In order for your Windows PC to play HEVC videos, you need to be running Windows 10. While H.264 can identify macroblocks up to 16 x 16 pixels in size, H.265 can work with macroblocks as large as 64 x 64 pixels. One of the key ways H.265 is more efficient goes back to those macroblocks we mentioned. With H.265, the video data takes up less space or needs less transmission capacity than with H.264 but with the same level of quality. H.264 isn’t efficient enough for 4K streaming, but with H.265 4K content is compressed to a size that allows for streaming over something like Netflix, assuming you have the recommended Internet speed. HEVC compresses video in a more efficient manner than AVC but with the same level of image quality. AVC is short for Advanced Video Coding, and the standard was first published in 2003. AVCīefore HEVC / H.265, the standard was AVC / H.264. This means the frame will ultimately be a smaller, more digestible size. One compression tactic H.265 uses is identifying macroblocks, which may all be the same color or same image (such as a background) for numerous frames, and storing/streaming them in blocks instead of storing / streaming the color of each individual pixel.

Then, a video decoder decompresses it to output a series of decoded frames.

An H.265 video encoder compresses the source video (a series of frames), and that bitstream is then stored or transmitted. Major streaming services including Netflix, Amazon and Hulu all use HEVC for at least some of their streams, even some that are 1080p. With H.265, you can stream in 4K, rather than relying on a physical storage source, such as a Blu-ray disc. Developed by ISO/IEC MPEG (Moving Picture Experts Group) and ITU-T VCEG (Video Coding Experts Group), the H.265 standard was first made available in 2013.

H.265 also dictates the types of tools that the codec can use. It dictates a standard approach to encoding and decoding video. It’s also known as HEVC, which stands for High Efficiency Video Coding.

H.265 is the latest international standard for video compression (you can find the full specification here). It’s the successor to H.264, also known as AVC. H.265, also known as HEVC, is the most current video codec.
