A family of 15 audio and video standards from the Moving Picture Experts Group (MPEG). Development began in 2010, and the first standard was approved in 2013. The "H" was derived from High Efficiency; for example, the H.265 video codec is entitled High Efficiency Video Coding (see
HEVC). The High Efficiency Image File format stores twice as much data as JPEG (see
HEIF). The streaming format is known as the MPEG Media Transport (see
MMT), and there are three standards that deal with surround sound (see
3D audio and
surround sound). See
MPEG.
