AUDIO/VIDEO SYSTEM INTEGRATED SATELLITE AND TERRESTRIAL DIGITAL MULTIMEDIA BROADCAST WHICH HAS PICTURE IN PICTURE FUNCTION AND METHOD FOR SIMULTANEOUSLY DISPLAYING SATELLITE AND TERRESTRIAL DIGITAL MULTIMEDIA BROADCAST ON PIP SCREEN

摘要

One audio-frequency/video frequency system, have the function of a PIP (scheming in figure) and receive satellite and terrestrial DMB (digital multimedia broadcasting) broadcast singal and a PIP display methods, is provided to by using PIP functions and watches a satellite broadcasting plan and a terrestrial DMB broadcast plan respectively. One audio-frequency/video frequency system includes a Satellite Digital Multimedia module (50), a terrestrial DMB module (60), a storage unit (20), a display (40), an image scaler (70) and a controller (10). It is selected relative to the storage element of artificial satellite and terrestrial DMB plan and user register plan storage EPGs (electronic program guide) by a user. Display receives a predetermined video signal and shows an image corresponding with vision signal. Image scaler receives digital multimedia vision signal from artificial satellite and terrestrial DMB module, and processing receives signal and enters a PDP signals, is output to the PDP signals of display. Controller checks whether that current time corresponds to the registered program broadcasting time of a user, when pass through one of artificial satellite and terrestrial DMB module, when one DMB plans are being received, activate DMB modules, the registered plan of user is provided when current time program broadcasting time registered corresponding to user, controls image scaler to show the plan being received simultaneously and to the registered plan of the user of display.
