This document provides context to the 2052 "family" of the core standard and the related, optional, format conversion document(s). This document is introductory and does not contain any normative requirements.

Scope – SMPTE ST 2052-1:2013

This Standard defines the SMPTE profile of W3C Timed Text Markup Language (TTML), designated SMPTETT, which may represent Captions or Subtitles. It identifies the features from TTML required for interoperability between display systems for the format. In order to preserve certain semantic features of the input formats, SMPTE-TT also defines some standard metadata terms to be used, and some extension features not found in TTML.

Scope – SMPTE RP 2052-10:2013

This recommended practice document defines the preferred method of converting from CEA-608 data streams to SMPTE-TT (as defined in SMPTE ST 2052-1). This document details how such a conversion can be made, and defines some constraints on the translation process so that the resulting SMPTE-TT file is interoperable between SMPTE-TT implementations.

Scope – SMPTE RP 2052-11:2013

This recommended practice document defines the preferred method of converting from CEA-708 data streams to SMPTE-TT (as defined in SMPTE ST 2052-1). This document details how such a conversion can be made, and defines some constraints on the translation process so that the resulting SMPTE-TT file is interoperable between SMPTE-TT implementations.
