TimedText/IMSC1 3 Implementation Report

Introduction

The following is the implementation report for the IMSC Text Profile 1.3 specification. This implementation report demonstrates that the CR exit criteria for transition to Recommendation, which are defined in the TTWG charter have been met, copied here for convenience:

When considering suitability to advance any feature beyond Candidate Recommendation, at least two independent factors of verification for each normative requirement must be demonstrated, which may come, as relevant for that requirement, from any of:

• Presentation implementation
• Content-producing implementation
• Validating implementation

Do not hesitate to direct questions and/or results to the TTWG mailing list [1] and/or the IMSC editor (Pierre-Anthony Lemieux <pal@sandflow.com>) with [imsc] at the start of your email's subject.

Implementation report

All features of IMSC 1.3 not already included in IMSC 1.2 are listed here.

Since every feature of IMSC 1.3 is implemented and documented either (a) as part of the IMSC 1.2 implementation report or (b) as part of the TTML2 implementation report, this implementation report lists no tests or implementations.
