Voluntary Product Accessibility Template (VPAT) Review

Criteria 1194.24 - Video and multimedia

This category addresses communication devices used by people who are deaf, hard of hearing, visually impaired, or speech impaired to communicate over networks designed to carry voice. Whenever a device transmits and receives voice over a telecommunications. 

There is misconcesption that with modern technology that this section and several of the criterion witin it are no longer relevent however, upon really analyzing each criterion the core of the acessibility piece is still relevent regardless of old technology or new technology.

The CSU reviews this section in relation to functionality regardless of that the product or service. The subsections below will contain the following:

  • The text of the section 508 criterion
  • Explanation of what the criterion is asking along with resource links if available
  • Cross reference information if applicable
  • Verification notes we give our campuses for reviewing VPAT's
  • Information on how this looks like it will overlay into the Section 508 Refresh
Criterion Resources

Criteria 1194.24(a)

All analog television displays 13 inches and larger, and computer equipment that includes analog television receiver or display circuitry, shall be equipped with caption decoder circuitry which appropriately receives, decodes, and displays closed captions from broadcast, cable, videotape, and DVD signals. As soon as practicable, but not later than July 1, 2002, widescreen digital television (DTV) displays measuring at least 7.8 inches vertically, DTV sets with conventional displays measuring at least 13 inches vertically, and stand-alone DTV tuners, whether or not they are marketed with display screens, and computer equipment that includes DTV receiver or display circuitry, shall be equipped with caption decoder circuitry which appropriately receives, decodes, and displays closed captions from broadcast, cable, videotape, and DVD signals

Clarification:

This is addressing the ability of the product to receive, decode and display closed captions.

  • The product should accurately receive captions (turn on captions and play media known to have captions; verify the captions are available).
  • Open or closed caption decoding capabilities should be included in the product.
  • The product should display captions correctly.
  • This section of the law only applies to analog products with displays whose diagonal screen size is equal to or larger than 13 inches. For digital video and multimedia products the law applies to screen sizes that are 7.8 inches vertically for widescreen displays, or 13 inches for conventional displays.

Section 508 Refresh

  • 411.1 Closed Captioning Processing Technologies - General
  • 411.1.1 Closed Captioning Processing Technologies - General - Decoding of Closed Captions
  • 411.1.2 Closed Captioning Processing Technologies - General - Pass-Through of Closed Caption Data
  • 412 Audio Description Processing Technology

Verification Notes:

  • When Supports with Exceptions is chosen look for the following information in Remarks and Explanation column:
    • What is the impact of the user’s inability to complete any core functions of the application due to the exception or lack of support for this criterion.
  • Note that for responses that include Supports with Exceptions and Not Supported drive the completion of the elements of the Accessibility Road Map and information to users on the Accessibility Statement.

Criteria 1194.24(b)

Television tuners, including tuner cards for use in computers, shall be equipped with secondary audio program playback circuitry.

Clarification:

All TV tuners must have the ability to play secondary audio. From  USPTO

This is addressing the need for the equipment to have the ability to play audio descriptions.

  • The intent of this law is to enhance multimedia experiences for those who are visually impaired. Often secondary audio includes an audio description of the visual content of a presentation that is synchronized with the existing soundtrack.
  • Although this portion of the law does not include TVs or displays without tuner circuitry, Functional Performance Criterion 1194.31(a) requires agencies to provide "at least one mode of operation and information retrieval that does not require user vision". Therefore it is a good practice to purchase displays with SAP receiving capabilities.
  • It is a good practice to ensure that TVs and displays offer SAP capabilities if they support an agency's mission. Attaching stand-alone SAP circuitry can do this.
  • The Media Access Group at WGBH publishes a series of consumer guides to issues related to media access.
