Internet Video Coding

Article summary

Internet Video Coding (ISO/IEC 14496-33, MPEG-4 IVC) is a video coding standard. IVC was created by MPEG, and was intended to be a royalty-free video coding standard for use on the Internet, as an alternative to non-free formats such as AVC and HEVC. As such, IVC was designed to only use (mostly old) coding techniques which were not covered by royalty-requiring patents. According to a blog post by MPEG founder and chairman Leonardo Chiariglione in 2018, "IVC is practically dead." He said that three companies had made statements equivalent to "I may have patents and I am willing to license them at FRAND terms" covering IVC, meaning that implementations might have to pay money to the companies. These statements meant that IVC was not clearly a royalty-free video coding format; those companies would need to be contacted to determine whether they had essential patents and to determine the terms for their use which might involve the payment of some fees. The ITU-T/ITU-R/ISO/IEC patent policy defines three types of patent licensing. The goal for IVC was to only use techniques patented under type 1 (royalty-free), while the three companies said they may have patents under type 2 (possibly requiring royalty payments).…
