Is a format established by Japanese companies in 2006. Designed for storage of video in resolution HD. The basis of lay encryption algorithm MPEG-2. Today, there are two HD-resolution videos: 1080p and 720p. This format is positioned as a direct alternative to obsolete DV in the home video recording sphere.
This format was originally created as an alternative to mp3. The idea was to achieve a small file size with better sound quality. The first versions weren’t quite successful, but with the development of AAC, it became possible to store sound with less loss of quality, and with the same file sizes as that of mp3.
