Description

ABSTRACT:
Apparatus to suppress image deterioration in a data, broadcast thereby providing a display with quality, wherein a video signal separated from a reception signal by a demultiplexer is outputted to a converter section through an MPEG decoder section. When the video signal is a data broadcast and in a 480I signal format, a CPU controls a converter section to perform size-scaling on the video signal and to convert it into a 480p signal format. A data processing section generates a video signal having a 480p signal format of a corresponding character or figure, under control of the CPU, on the basis of a data signal. A synthesizer section synthesizes together the two video signals processed by the converter section and data processing section and inputs the synthesized signal to a D/A converter. The D/A converter converts an input video signal into an analog signal and outputs it to a display unit.
