Media and Entertainment Interest Group

This is the Wiki for the W3C Media and Entertainment Interest Group (formerly the Web and TV Interest Group), used to organize work in the IG. Higher-level information about the IG is available on the main home page of the group. The Interest Group reviews existing work and identifies requirements and potential solutions for the Web and audio-visual entertainment media (TV, movies, etc). The development of Web standards, when required, takes place in other working groups.

Task Forces


Media Timed Events Task Force

  • Cloud Browser Task Force
    • The goal of the Cloud Browser TF is to discuss support for web browser technology within devices such as HDMI dongles and lightweight STBs (set-top boxes) which may not be able to run a browser locally. A solution is to bring the processing of the browser to the cloud. The Task Force looks into use cases, requirements and gaps in cloud browser architecture.
  • (Closed) Testing TF [testing]
    • Identify Requirements for testing from a “Web and TV” perspective
    • act as a bridge between ongoing activities in W3C and other organizations interested in testing W3C specifications
  • (Closed) Timed Text [tt]
    • Develop recommendations to facilitate the use of TTML and WebVTT content on the Web, including interoperability with other timed text formats.
