We, W3C Member MovieLabs, hereby submit to the Consortium the following specification, comprising the following document(s) attached hereto:
which collectively are referred to as "the Submission". We request the Submission be known as the TTML-WW-PROFILES Submission.
This submission specifies two profiles for use with the upcoming Timed Text Markup Language (TTML) Version 2.0: 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.
Both profiles are based on the Common File Format & Media Formats Specification (CFF) developed by Digital Entertainment Content Ecosystem (DECE), and benefit from the technical consensus, conformance testing and implementation experience gathered there. The text Profile profile is intended as a superset of SDP-US, which is a subset of CFF. The image profile extends a subset of TTML with the SMPTE Timed Text (SMPTE-TT) image support.
DECE is an industry forum with more than 80 members across the content and consumer electronics community.
The statements in this section are made by MovieLabs.
MovieLabs hereby grants to the W3C a perpetual, nonexclusive, royalty-free, world-wide right and license under any MovieLabs copyrights on this contribution, to copy, publish and distribute the contribution under the W3C document licenses.
Additionally, should the Submission be used as a contribution towards a W3C Activity, MovieLabs grants a right and license of the same scope to any derivative works prepared by the W3C and based on, or incorporating all or part of, the contribution. MovieLabs further agrees that any derivative works of this contribution prepared by the W3C shall be solely owned by the W3C.

The organization I represent on the W3C Advisory Committee agrees to offer licenses according to the W3C Royalty-Free licensing requirements described in section 5 of the 5 February 2004 W3C Patent Policy for any portion of the Submission that is subsequently incorporated in a W3C Recommendation.
N/A
We suggest that the Consortium consider the submission as basis for the development, within the Timed Text Working Group, of TTML profiles appropriate for subtitle and caption delivery applications worldwide.
Until such a time that the contribution is used towards a W3C Activity, change control of the Submission shall remain with MovieLabs.
To help with this work, we expect to be able to provide a non-resident document editor to the Consortium.
