Abstract:
In an image signal processing device provided with VIF and AIF processors for separating a radio frequency composite image signal outputted from a tuner into a video intermediate frequency signal and an audio intermediate frequency signal, a video output unit for processing and displaying a TV image signal or a HTML image signal on a color picture tube and an audio output unit for processing and outputting the audio intermediate frequency signal from the AIF processor or a HTML audio signal to a speaker, a HTML data receiving apparatus, further comprising:a TV decoder modulating the image intermediate frequency signal outputted from the VIF processor to a TV image signal and a HTML signal and slicing the HTML signal thereby converting to a text code; and a HTML decoder receiving the text code from the TV decoder and restoring HTML image and HTML audio data signals from text data, wherein the HTML decoder comprises: an interface interfacing data between an external microcomputer and a data bus; a CPU restoring the HTML image and audio data from the text data outputted from the TV decoder; a memory unit storing the restored HTML image data and HTML audio data; a key input controller controlling a key input; a graphic processor converting the HTML image data signal to an analog signal and performing on-screen and graphic processes; and a D/A converter converting the HTML audio data signal from the memory unit to an analog signal.
