From W3C Wiki

The session started from a presentation of the feature of the web-based signage and requirements for the browser. Although the embedded browsers are useful as web-based signage terminal devices, there are still specific requirements for the signage services. The API ideas such as auto-pilot API and rich presentation API were shown and discussed regarding the proper WGs where such APIs would be considered.
In addition, the results were provided to Web-based Signage Business Group and reflected the discussion in the review of a draft charter for the newly proposed Web-based Signage WG.
