Abstract
An apparatus for providing described television services includes a computer for receiving and storing description data corresponding to an audiovisual program; an encoder for encoding the description data into a program signal corresponding to the audiovisual program; and a receiver which receives the encoded program signal and extracting the description data from the encoded program signal. A text-to-speech converter converts the description data into a speech signal corresponding to the description data, and a speaker provides the speech signal to a viewer. Similarly, a method for providing described television services includes the steps of generating description data corresponding to an audiovisual program; encoding the description data into a program signal of the audiovisual program; and decoding the encoded program signal, whereby the description data is extracted from said encoded program signal. Once the description data is extracted, the description data is converted into a speech signal corresponding to the description data, and the speech signal is provided to a viewer.
