Guidelines for Usage

Actual types of Program Related Text are identified by this element, LANGUAGE.USAGE, and should be selected from a picklist of options.

A different element, DESCRIPTION.PROGRAMRELATEDTEXT, contains either the actual text (if of limited length) or indicates a separate, distinct, related file containing that text or a separate audio track. Many Digital Asset Management Systems will associate files that are cataloged separately, but related to an item.

Use the element RELATION.TYPE and RELATION.IDENTIFIER to refer to the presence and identification of these other related formats and forms of the primary audio presentation for a resource.

Use the element LANGUAGE to identify the actual language captured in alternative audio.

The various permutations of Program Related Text may include the following:

  1. A transcript may exist as a text document.
  2. Speech-to-Text conversions may exist as (a) a text document, or (b) an electronic file with timecodce synchronization data.
  3. Closed Captions may exist as (a) a text document, (b) an electronic file with timecode synchronization data, (c) as a video program or broadcast with captioning encoded on SMPTE line 21 of the video signal (NTSC standard), or (d) as data encoded within the "picture user_data" portion of the video stream in DTV (ATSC standard).
  4. Open Captions may exist as (a) a text document, (b) an electronic file with timecode synchronization data, (c) as a video program or broadcast with captioning encoded on SMPTE line 21 of the video signal (NTSC standard), (d) as data encoded within the "picture user_data" portion of the video stream in DTV (ATSC standard), or (e) as a completely separate track of text or its graphical representation (DVD-Videodisc standard specification or QuickTime tracks specification).
  5. Subtitles may exist as (a) a text document, (b) an electronic file with timecode synchronization data, (c) as a video program or broadcast with captioning encoded on SMPTE line 21 of the video signal (NTSC standard), (d) as data encoded within the "picture user_data" portion of the video stream in DTV (ATSC standard), or (e) as a completely separate track of text or its graphical representation (DVD-Videodisc standard specification or QuickTime tracks specification).
