ABSTRACT:
A video data transfer system which increases the rate of capturing video data into a system memory without being affected by a data bus and which prevents the display of data on a display unit from being affected even when data is being captured. Video data from a video processor21is sent, not via a frame buffer14but via a capturing-only path26,directly to a system bus17.This means that video data may be captured into a system memory18regardless of the status of a real time output path25.On the other hand, video data is sent to a display16via the real time output path25provided independently of the capturing-only path26.This means that video data may be sent to the display16at a constant rate regardless of whether or not data is being captured.
