It seems that audio and video compression is undergoing its own version of Moore’s Law progression, halving the required storage space or transmission bandwidth every few years. The Versatile Video Coding (VVC), or H.266, standard finalized July 6, 2020, by the Joint Video Experts Team (JVET). The standard is said to have a 30 – 50% better compression rate than the HEVC H.265 standard adopted in 2013, which was about 30 – 50% better than H.264, adopted in 2003. Naturally, the math is complex and compression encoding and decoding times are pretty hefty right now, but you know how that goes–someone’s going to design a chip, and next thing you know it’ll be part of your earphones.
We’ll see if ATSC 3 NextGen will include the standard in upcoming set-top boxes and televisions. H.265 has had some trouble with patent quibbles, which could lead to accelerated adoption of the newer H.266 standard.
