The Internet Video Codec (NETVC) is a standardization project for a royalty free video codec hosted by the IETF.[1] It is intended to provide a royalty-free alternative to de facto standards such as MPEG-4 and HEVC that require licensing payments for many uses.

The July 2015 basic draft requirements for NETVC are support for a bit depth of 8-bits to 10-bits per sample, 4:2:0 and 4:2:2 chroma subsampling, low coding delay capability, feasible real time decoder/encoder software implementations, temporal scalability, and error resilience tools. [2] The July 2015 optional draft requirements for NETVC is support for a bit depth of up to 16-bits per sample, 4:4:4 chroma sampling, RGB video, auxiliary channel planes, high dynamic range, and parallel processing tools.[2]

On March 24, 2015, Daala codec was presented to the IETF as a candidate for NETVC.[1][3][4] Daala coding techniques have been proposed to the IETF for inclusion into NETVC.[5]

On July 22, 2015, Cisco Systems' Thor video codec was presented to the IETF as a candidate for their NETVC video standard.[6] Thor is being developed by Cisco Systems and uses some Cisco elements that are also used by HEVC.[7] The Constrained Low-Pass Filter (CLPF) and motion compensation that are used in Thor were tested with Daala.[8]

At the IETF there are now also other partners involved in the development of NETVC.[7][8]


The planned schedule for the development of NETVC is:[9]

  • July 2016: Informational document on requirements and evaluation criteria.
  • May 2017: Standards documents on codec specification and storage format specification. Informational document on reference implementation.
  • December 2017: Informational document on test results.
