Introduction In the context of WebRTC, there is currently no consensus on the video codec(s) that need to be mandatory to implement. In order to reach a consensus, the RTCWEB chairs have solicited internet-drafts naming proposed mandatory-to-implement video codecs (c.f. [rtcweb-mail]). This draft gives some arguments in favor of H.264. 2. Terminology In this document, the key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" are to be interpreted as described in RFC 2119 [RFC2119]. 3. Rationale and Position Many videoconferencing systems exist today (e.g. fact sheets of services at [h264-ftob]), mainly for professional services but also for individual consumers. We believe that WebRTC, when used as a mean to interconnect Web browsers to these existing services, can be a driver for enabling more users to access them. As an example, all Orange video conferencing systems operate using the H.264/AVC technology. H.264/AVC benefits from many available implementations, tuned for different architectures, and has clear licensing conditions. VP8 has no footprint in this market, independent implementations are rare, licensing conditions are not yet clarified (free license offered from one patent owner while MPEG LA operates a Patent Pool with at least 12 members (c.f. [press-article])). With this current status, it is believed that incorporating the mandatory to implement video codec having the bigger footprint will permit a better adoption and interconnection of WebRTC to existing services leading to a successful standard. Hence we strongly support H.264/AVC to be part of the mandatory to implement codecs. Marjou & Philippe Expires April 18, 2013 [Page 3] Internet-Draft Video codec for WebRTC October 2012 4.
