Abstract

This document specifies two profiles of [TTML1]: a text-only profile and an image-only profile. These profiles are intended to be used across subtitle and caption delivery applications worldwide, thereby simplifying interoperability, consistent rendering and conversion to other subtitling and captioning formats. The text profile is a superset of [SDPUS].

Both profiles are based on [SUBM].

Status of This 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 http://www.w3.org/TR/.

This document was published by the Timed Text Working Group as a Candidate Recommendation. This specification is intended to become a W3C Recommendation. If you wish to make comments regarding this document, please send them to public-tt@w3.org (subscribe, archives) with [imsc] at the start of your email's subject. All comments are welcome. This Candidate Recommendation is expected to end no sooner than 31 December 2014.

For this specification to exit the CR stage, the following conditions detailed  will have to be met:

• there must be at least two independent, interoperable implementations of each feature. Each feature may be implemented by a different set of products, there is no requirement that all features be implemented by a single product. For the purposes of this criterion, we define the following terms:
  • Independent: Each implementation must be developed by a different party and cannot share, reuse, or derive from code used by another qualifying implementation.
  • Interoperable: Qualitatively interoperable at at a judgment level, not necessarily for every spec assertion. A test suite may be used as guidance for the qualitative decision.
• the working Group will provide a implementation report documenting implementations of each feature.

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.
