Status of the Document


This section describes the status of this document at the time of its publication. Other documents may supersede this document. A list of current W3C publications and the latest revision of this technical report can be found in the W3C technical reports index at https://www.w3.org/TR/.

This document was published by the Second Screen Working Group as a Candidate Recommendation. This document is intended to become a W3C Recommendation. Comments regarding this document are welcome. Please send them to public-secondscreen@w3.org (subscribe, archives). W3C publishes a Candidate Recommendation to indicate that the document is believed to be stable and to encourage implementation by the developer community. This Candidate Recommendation is expected to advance to Proposed Recommendation no earlier than 30 November 2017.

Please see the Working Group's implementation report.

This document builds on the group's experience on presenting web content on external presentation-type displays, and re-uses patterns and design considerations from the Presentation API specification whenever appropriate [PRESENTATION-API].

Although this document is still a work in progress and is subject to change, the Working Group believes that the API surface is stable. Most of the remaining issues listed on the issue tracker are considered minor at this stage except for Issue #41.

Issue #41 discusses the set of media playback features that remote playback devices are expected to support. The group will seek further developer feedback and implementation experience to identify any interoperability issues around these features when used during remote playback, and will further clarify the specification based on feedback received.

For other issues or concerns, it is possible to file a bug or send an email to the mailing list. For small editorial changes like typos, sending a pull request is appreciated.

The Working Group invites everyone to review this document, and will work with relevant groups at W3C to conduct horizontal reviews on accessibility, internationalization, privacy, security and technical architecture principles.

No feature has been identified as being at risk.

The Second Screen Working Group will develop a test suite for the Remote Playback API during the Candidate Recommendation period and prepare an implementation report. For this specification to advance to Proposed Recommendation, two independent, interoperable implementations of each feature must be demonstrated, as detailed in the Candidate Recommendation exit criteria section.

Publication as a Candidate Recommendation does not imply endorsement by the W3C Membership. This is a draft document and may be updated, replaced or obsoleted by other documents at any time. It is inappropriate to cite this document as other than work in progress.
