Cisco has hired patent lawyers and consultants familiar with video codecs and created a development process which they say allows them to work through the long list of patents in the space, and continually evolve their codec to work around or avoid other HEVC related patents. http://www.testbells.com/300-135.html Two weeks ago Cisco open-sourced the code and contributed it to the Internet Engineering Task Force (IETF), which already has a standards activity to develop a next-generation royalty free video codec in its NetVC workgroup. This is a group Mozilla has been active in and has been working on technology they call Daala, which they want to be the successor to HEVC.
