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.

Template for Use Cases

Please use this template when proposing use cases that should be discussed by the IG.

Report your use cases in Bugzilla under the appropriate Product

high level description/overview of the use case 
If needed, diagrams, pictures or code snippets can be used to better describe the use case.

Explanation of benefit to ecosystem and why is relevant for this group.

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)

other use cases, proposals or ongoing standardization activities which this use case is dependent on or related to.
If you are aware of any existing work (also in other organizations) covering a similar use case, you can mention it here.

If the use case fall into category #3 above, write here your proposal

Work in Progress

Next Steps

The following table summarize next steps for IG activity as discussed during the last F2F and described in the IG report. For each topic, a modearator is identified that is responsible to coordinate the activity in that area.

Accessibility  ? Already handled by existing WGs. Is there any other aspects of this topic that needs to be discussed?
Parental Control  ? Partially addressed by MPTF (for in-band content). Maybe need a broader discussion though, even outside the IG.
