Windows Media Center works with the following Windows Vista accessibility features: Narrator, Magnifier, and Descriptive Video Services (DVS). You can use Narrator to convert text to speech, set Magnifier to enhance the view of your screen, and activate Descriptive Video Services for your TV.
Narrator is a text-to-speech utility program in Windows Vista for users who are blind or have impaired vision. Narrator reads what is displayed on your screen: the contents of the active window, menu options, or the text you have typed.
Windows Media Center has basic navigational support for Narrator and other screen readers that work with Active Accessibility 2.0. For information about how to use Narrator in Windows Vista and Windows Media Center, see Hear text read aloud with Narrator.
Magnifier is a display utility program in Windows Vista that makes the screen easier to read for users who have impaired vision. Magnifier creates a separate window that displays a magnified portion of your screen.
Windows Media Center supports Magnifier and other screen magnifiers that work with DirectX, a Microsoft suite of multimedia application programming interfaces that are built into Windows operating systems.
For information about how to use Magnifier in Windows Vista and Windows Media Center, see Make items on the screen appear bigger (Magnifier).
DVS provides visually impaired viewers with additional information about the images on the screen. DVS is not available in all regions. You can contact your TV service provider to inquire about the availability of DVS in your region.
If your computer has no TV tuner, an optional analog or digital TV tuner is required to play and record TV in Windows Media Center.
On the start screen, scroll to Tasks, click settings, click TV, and then click Audio.
Under Audio, change the selection to SAP by using the + and - buttons on the screen.
This activates DVS. Note that the Second Audio Program (SAP) channel may contain an additional voice track that has voiceover commentary, DVS, or a foreign-language translation.
After you have completed your changes, click Save to return to the TV settings screen.
