Abstract

An electronic program guide device includes a demultiplexer for filtering a multiplexed bit stream transmitted through a transmission channel with respect to a selected channel and separating the filtered multiplexed bit stream into a video stream and an audio stream; a controlling part coupled to the demultiplexer for extracting electronic program guide information from the multiplexed bit stream and storing the extracted electronic program guide information in a memory; a video processing part coupled to the demultiplexer and the controlling part for decompressing the video stream from the demultiplexer to restore an original image, synthesizing the original image and the electronic program guide information, and displaying the synthesized original image and the electronic program guide information on a screen; an audio processing part coupled to the demultiplexer for decompressing the audio stream from the demultiplexer; a voice source processing part coupled to the controlling part for vocally synthesizing the electronic program guide information received from the controlling part; and a selecting part coupled to the audio processing part and the voice source processing part for selecting an output from the audio processing part and the voice source processing part and sending the output to a speaker.
