Does DTV Provide Emergency Video Descriptions?
FCC rules state that broadcasters must orally describe any emergency information that is shown on the screen. With DTV, broadcasters have more audio channels on which to provide the video description. Emergency information that is not orally described must be accompanied by an aural tone which instructs individuals with vision disabilities to turn to a radio or another source for more information. Contact your local broadcasters to determine whether video description is offered. Video descriptions are a way to inform people who are blind or have other vision disabilities of what is happening on the television screen. Video description is the insertion of verbal descriptions about the setting and/or action in a program when information about these visual elements is not contained in the audio portion of the program. These descriptions supplement the regular audio track of the program.
