Course Description
Video, TV and Image technology today dominates Internet Services. Whether it be for live TV, Streamed movies or video clips within social media video images are everywhere. The long-term efficiency of services depends upon the methods and mechanisms used to encode these services. We have relied upon the developments from the Digital Video Broadcast industry, ISO, MPEG and the ITU to provide us with standard ways to achieve this. However the patent royalty cost is now considered to be holding back this efficient development. All commercial users of the normal encoding used such as H.264, H.265, HEVC and other standardised codecs are required to pay royalties for using this technology through a firm of US patent Lawyers known as MPEG-LA. Each new ITU- T standard encoding requires new and increased payments.
The Alliance for Open Media is founded by leading Internet companies focused on developing next-generation media formats, codecs and technologies in the public interest. The new Alliance is committing its collective technology and expertise to meet growing Internet demand for top-quality video, audio, imagery and streaming across devices of all kinds and for users worldwide. The aim is to develop royalty free standardized encoding based upon the technology contributed by its members.
This course provides a technical study of Video Coding and the technologies which the developing Open Media implementations are based upon. These include Google’s VP8/VP9 and their eventual VP10, Cisco Thor, and Mozilla Daala. It will examine some of the key video encoding technologies and some of the patent aspects that are key to success.
No prior background in Video or TV encoding will be assumed and the course will concentrate upon functional aspects and technology comparisons rather than in the construction of the code. Hands-on exercises will provide demonstrations of the techniques that are used and some examples of implementations will be considered.
