Do not confuse a video coding format with a video format.
You can read this post about video formats.
List of Video Coding Formats
Video coding formats featured on this post:
- H.261
- MPEG-1 Layer 2
- H.262 / MPEG-2 Part 2
- H.263
- H.264 / MPEG-4 part 10
- H.265
- H.266
H.261
H.261 was the first standard for videoconferencing video codec.
It was developed by ITU-T.
It was first published in 1988.
MPEG-1 Layer 2
MPEG-1 Layer 2 was dedicated to video.
It was published by ISO.
Later MPEG standard parts related to video were published jointly with ITU-T recommendations.
H.262 / MPEG-2 Part 2
H.262 is also known as MPEG-2 Part 2 and ISO/IEC 13818-2.
It was first published in May 1996, though its development started in 1995.
It was the first one to be maintained jointly by ITU-T and ISO/IEC MPEG.
MPEG-3 was not published because MPEG-2 reached similar characteristics.
H.263
H.263 was released in March 1996. H.263+ was released in February 1998 and H.263++ in November 2000.
Take note that H.263 was published one month than H.262.
It was initially conceived to be used on applications that required low speeds, such as RTC, RDSI or mobile networks and considered only low resolution images.
Lately, 5 video formats were considered: SQCIF, QCIF, CIF, 4CIF and 16CIF.
The standard is used in H.320, H.323, SIP and RTSP.
H.264
H.264 is also known as Advanced Video Coding (AVC) and MPEG-4 part 10.
It was first published in 2004.
H.265
H.265 is also known as High Efficiency Video Coding (HEVC) and MPEG-H Part 2. It was released in 2023. It was developed jointly between ITU-T, ISO and IEC.
It was first published in 2013.
H.266
H.266 is also known as Versatile Video Coding (VVC), ISO/IEC 23090-3 and MPEG-I part 3. It was developed jointly between ITU-T, ISO and IEC.
It was first published in 2020.
