COMPUTERIZED ADVERTISEMENT BROADCASTING SYSTEM
First Claim
1. A computerized advertisement broadcasting system that uses the motion picture expert group (MPEG) technical conventions, comprising a data memory card for storing an NPEG compressed bit stream;
- and a console that includes a memory card plug-in slot for inserting the memory card, wherein the console also performs the function of drawing the MPEG compressed bit stream out from the memory card and then converting it into video signal output and left and right channel analogue audio signal output

Abstract
A computerized advertisement broadcasting system that employs the technical conventions lay down by the motion picture expert group (MPEG). The system comprises a console and separable data memory cards, where the advertising program is stored within the data memory card in an MPEG compressed data stream format. The advertising program can be broadcast repetitively by the console Since the advertising program is stored digitally within a data memory card, programs can be changed simply by inserting a new data memory card. Furthermore, the system is assembled from a group of electronic devices. Therefore, unlike a video cassette broadcasting system that contains moving parts vulnerable to mechanical breakdown and tape wear leading to the deterioration of video image, the failure rate and maintenance cost of this system are low
