History
On March 24, 2015,
On July 22, 2015, Cisco's Thor video codec was presented to the IETF as a candidate for their NETVC video standard.[7] Thor is being developed by Cisco Systems and uses some Cisco elements that are also used by HEVC.[8] The Constrained Low-Pass Filter (CLPF) and motion compensation that are used in Thor were tested with Daala.[9]
As of July 2015, in addition to Xiph and Cisco, there were also other participants involved in the project.[8][9]
At IETF meeting 101 in March 2018, xvc was presented by Divideon as another candidate. Thor developer Steinar Midtskogen confirmed that a subset of xvc that Divideon considered royalty-free had better compression than Thor at comparable complexity settings. It was agreed at that time to pause physical meetings of the working group to see how the market for royalty-free video formats further developed, given that the teams behind several of the format candidates that had been presented had chosen to join the AV1 standard development initiative of the Alliance for Open Media consortium, which had similar goals.[10]
After publishing RFC 8761 "Video Codec Requirements and Evaluation Methodology"[3] in April 2020, the Internet Video Codec working group was closed.[11]
Schedule
The planned schedule for the development of NETVC was:[12]
- April 2018: Informational document on requirements and evaluation criteria.
- July 2018: Informational document on test results, initial codec specification and reference implementation.
- December 2018: Standards documents on codec specification and storage format specification.
