From Web and TV IG
Web and TV Interest Group
This is the Wiki for the W3C Web and TV Interest Group (Web&TV IG), used to organize work in the IG. Higher-level information about the Web&TV 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 TV. The development of Web standards, when required, takes place in other working groups.
- TPAC 2013 is coming soon! See draft agenda linked above
- 30 July 2013: W3C announced the approval of the Web and TV IG charter in response to the call for review. The charter's end date is 20 February 2015. The majority of commenters suggested that the group be approved with no changes. Also five commenters suggested changes and the charter text has been adapted to address those comments. A detailed disposition of comments is available: https://www.w3.org/2013/04/webtv-ac.html
- 29 October 2012: The IG held its F2F meeting at TPAC 2012 in Lyon, and discussed what should be done for the next Charter period. As the result, the group agreed to launch Task Forces for Testing, Recording/Downloading Media, Terminal APIs, Content Metadata/Synchronization, Stereoscopic 3D and TTML/WebVTT coexistence. See Task Forces below for the details on the Task Forces.
NOTE: the tag indicated near the Task Force name MUST be used when sending email to the IG list for topics related to that TF.
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
Media APIs TF [apis]
- Merges the work of the Recording and Downloading Media, Terminal Capabilities and Content Metadata Exposure and Content Synchronization TFs. with the following focus:
- Identify requirements for recording and downloading media
- Investigate requirements for discover and control of device capabilities (e.g. tuner control)
- Investigate how to expose TV metadata to web applications
- Investigate mapping between Media Element API and in-band metadata
- Synchronization of broadcast content and web applications up to frame accurate
Stereoscopic 3D Web [3dweb]
- Investigate impact of 3D Video/Graphics on HTML and other web standards
- (note: see notes of a breakout session on this topic during TPAC here http://www.w3.org/wiki/TPAC2012/3dweb)
Timed Text [tt]
- Develop recommendations to facilitate the use of TTML and WebVTT content on the Web, including interoperability with other timed text formats.
Closed or Dormant
- (Closed) Media Pipeline TF [mptf] — discuss requirements placed on the HTML5 video, audio and media interface by media formats that will be used for Web and TV
- Requirement document published: Adaptive Bitrate Requirements for HTML5 Media Element
- Requirement document published: Content Protection Requirements for HTML5 Media Element
- Led to the Encrypted Media Extensions proposal
- (Closed) Home Network TF — [hntf] identify gaps to enable discovery and control of devices and services in the local area IP network.

- Archives of the email@example.com mailing-list are publicly available. This mailing-list should be used for all technical discussions within the group.
- Archives of the firstname.lastname@example.org mailing-list are available to W3C Members only. Use of this second list should be restricted to administrative purposes
Template for Use Cases
This is a generic template for proposing use cases that should be discussed by the IG TFs. Note that TFs may extend the template if/as needed, so check with your TF moderator if you are not sure.
Submitter(s): company (name), ... Tracker Issue ID: ISSUE-NN Category How would you categorize this issue?: 1. gap in existing specifications (=> IG to draft a proposal for an existing WG) 2. require new specification/WG (=> IG to draft a proposal for W3C Director) 3. can be addressed as part of a guidelines document to be produced by the IG (=> proponent to draft some text for such document) Description: * high level description/overview of the goals of the use case * Schematic Illustration (devices involved, work flows, etc) (Optional) * Implementation Examples (e.g. JS code snippets) (Optional) Motivation: * Explanation of benefit to ecosystem * Why were you not able to use only existing standards to accomplish this? Dependencies: * other use cases, proposals or other ongoing standardization activities which this use case is dependant on or related to What needs to be standardized: * What are the new requirements, i.e. functions that don't exist, generated by this use case? Comments: * any relevant comment that is good to track related to this use case
IG Specific Processes
- TF handling rule to propose the creation of a task force
- TF charter template to precise the scope of a potential new task force
- Use Case template to be used as base for drafting a use case input document. Note that TFs may have their own further refined template (check TF page)
- Tracker is used to track issues and actions within the group. For help on how to use Tracker see the related web site. For a really quick intro see here
