What are H.26L, AVC and JVT?

These names are sometimes also used to refer to the H.264 video codec. H.264 is the result of the combined efforts of two standards bodies — the ITU (International Telecommunication Union) and ISO MPEG (International Organization for Standardization’s Moving Picture Experts Group) — that together formed a body called the Joint Video Team (JVT). ITU originally referred to this new technology as H.26L, while MPEG originally referred to this technology as AVC. During the development of the standard, some also referred to the codec as JVT. H.264, however, is emerging as the most commonly-used name.
