INTEGRATED VIDEO BROADCAST SYSTEM, PARTICULARLY CONCERNED WITH BROADCASTING LARGE IMAGES OR IMAGES INTEGRATED WITH PLURAL DATA

摘要

PURPOSE: An integrated video broadcast system is provided to supply a large image display system capable of directly transmitting video data to a video buffer from a hard disk without passing through a main memory device, so that a user can easily and quickly use video information. CONSTITUTION: A line buffer(9) exists between a hard disk(1) and a video buffer(5) without passing through a main memory device(3), in order to remove a delay phenomenon caused by the main memory device(3). The line buffer(9) has a capacity of storing divided unit data of video data. Unlike the main memory device(3) which runs at slow speed, the line buffer(9) receives the data in divided units, and almost does not delay the video data. Each of the divided data is transmitted to the video buffer(5) by the line buffer(9), to reproduce images at high speed.
