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.
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.

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
Description: high level description/overview of the use case If needed, diagrams, pictures or code snippets can be used to better describe the use case. Need/justification: Explanation of benefit to ecosystem and why is relevant for this group. 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) Dependencies: 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. PROPOSAL: If the use case fall into category #3 above, write here your proposal
