The Timed Text Working Group has published the First Public Working Draft of Simple Delivery Profile for Closed Captions (US). This document defines the behavior expected of a presentation processor using the player constraints for such an online delivery profile. The Simple Online Delivery profile is focused on streamlined delivery of closed captions on the Internet. This interoperability profile supports core TTML features to deliver content originating legacy formats such as CEA-608 and -708 content, and is targeted primarily for delivery in US markets. The Simple Delivery Profile for Closed Captions focuses interoperability using TTML 1.0 to support delivery of closed captions for video content. Other profiles based on TTML 1.0 may target other types of subtitles such as on-screen text or graphics. This interoperability profile is a proper subset of TTML 1.0 plus features required to support US Government closed captioning requirements for online presentation.
