3. Will televisions with digital tuners be able to process the audio services associated with

the digital signals?

Televisions with digital tuners should be able to process the audio services associated with the

digital TV signals through functions that are built into their systems. Consumers should confirm

with the manufacturer, owner’s manual or retailer prior to purchase to determine if this feature is

included in the digital TV.

For consumers who will be using a digital-to-analog converter box to receive digital over-the-air

television signals on an analog television, we note that some of the digital-to-analog converter

boxes that have been approved for NTIA coupon eligibility are capable of processing the

associated audio services that are broadcast by a digital television station. In particular, the

WGBH National Center for Accessible Media, located in Boston, Massachusetts, has found that

two specific coupon-eligible digital-to-analog converter boxes – the Digital Stream DTX 9900

and Insignia NS-DXA1 – have demonstrated the capability to pass through video description.

(Federal law provides for two $40.00 coupons per household to defer the costs of the digital-to-

analog converter boxes. Consumers may find out more information about this coupon program,

administered by the NTIA, at www.dtv.gov or at www.dtv2009.gov

, or by calling 1-888-DTV-

2009.) Coupons do expire 90 days after mailing.

However, because coupon-eligible digital-to-analog converter boxes are not required to have this

feature, consumers are advised to check with the manufacturer, owner’s manual or retailer prior

to purchase to determine if a specific digital-to-analog converter box will serve their particular

needs.

Accessing additional audio program streams (including video description) typically occurs either

though a designated button on the remote control or through an on-screen menu. Unfortunately,

if the controls on the television or digital-to-analog converter box are not accessible to people

with vision disabilities, it may be a challenge to obtain the descriptions. In such cases, the

consumer must know which audio stream the video description is on in advance, as well as how

to access this channel. We therefore urge consumers to ask the manufacturer or retailer how

audio streams are accessed prior to purchasing a digital television or digital-to-analog converter

box. In addition, the consumer should ask whether the on-screen menus – as well as the remote

controls that are used to access the on-screen menus – are accessible to individuals who have

vision disabilities. Finally, the consumer should contact local television stations to see if they are

transmitting video descriptions, and if so, for which programs.

Consumers using cable or satellite services should ask for additional information about the

availability of video description from their service providers. To the extent that cable systems,

satellite systems or other multi-channel video programming distributors receive programming

with video description, those video descriptions should be delivered to the consumer. As with

broadcast television, subscription-based television consumers must ensure that their television is

capable of displaying available video descriptions and that video description functionality may

be accessed by people with vision disabilities.
