First Public Working Draft: TTML Profiles for Internet Media Subtitles and Captions 1.1

October 17th, 2017

The Timed Text Working Group has published a First Public Working Draft of TTML Profiles for Internet Media Subtitles and Captions 1.1. This specification defines two profiles of [TTML2]: 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.
