ROM DATA TRANSMITTED IN THE VBI TO A PERSONAL COMPUTER THROUGH TELEVISION BROADCAST CHANNELS

摘要

A system that displays text and graphic information with broadcasted television images includes a VBI inserter (16) for inserting data into the VBI of a publicly broadcasted video signal. An associated personal computer (10) includes a VBI decoder for separating the data from the video signal. The separated data contains command and address information which instruct the PC to retrieve text/graphic information from a storage device, and display the information on a monitor (30). The broadcaster inserts data that retrieves text and graphic information which correspond to the television image displayed by the monitor. The retrieved text and graphic data may be stored for later viewing by the user.
