Abstract
A time/data adjustment device automatically synchronizes the time in a computer to the time information contained in signals from a broadcast satellite even when the computer is turned off. A broadcast station outputs video data and audio data of a broadcast program, electronic program guide (EPG) and time/date information from a satellite antennae. A geostationary satellite relays the signals to a earth station. A satellite receiving subsystem of the computer, using a stream separator, separates video data, audio data and other data, the EPG and date information are sent to the computer through a bus controller. In the computer, a device driver software acts as the interface between the subsystem and an operating system of the computer to renew the date data in the application software, and also inputs the date data in the real-time clock circuit.
