What is the format of hevc?

HEVC is a high-efficiency video coding format and a new video compression standard used to replace the H.264/AVC coding standard; HEVC’s main features include tree structure prediction and residual block segmentation , extended prediction block size, variable size block transform, integer inverse transform, multi-frame motion compensation prediction, etc.

HEVC is the abbreviation of High Efficiency Video Coding. It is a new video compression standard used to replace the H.264/AVC coding standard. On January 26, 2013, HEVC officially became an international standard.

In 2004, the ITU-T Video Coding Experts Group (VCEG) began researching new technologies to create a new video compression standard. In October of the same year, the H.264/AVC group investigated various potential technologies. At the VCEG meeting in January 2005, VCEG began to designate certain topics as "key technologies" for further research. A software code base called Key Technical Areas (KTA) was established in 2005 to evaluate these new "key technologies."

Video compression is already one of the essential home entertainment in our lives. Without it, we would live in a world with only dozens of TV channels around the world. Right now That's simply unimaginable. Digital technology first appeared in the UK. At that time, people already had television sets. Through the continuous evolution of digital technology, terrestrial TV channels quickly developed from 5 to more than 30, which greatly enriched people's daily life entertainment.
