The other is VCEG (Video Code Expert Group), which is a video coding expert group under the International Telecom Federation.

The standards developed by VCEG include H.261, H.262, H.263, etc. These standards have become a video compression standard for television conferences, and the latest H.264 is standard for new generation interactive video communications. The standards developed by MPEG include MPEG-1, MPEG-2, MPEG-4, MPEG-7, and MPEG-21, MPEG-1, known, MPEG-2, MPEG-4, for interactive multimedia Communication has a compressed standard, and MPEG-7 is a compression criterion established for Internet video retrieval.
