Abstract
A video capture system and method whereby video frames or images, which are received in one of a plurality of possible formats, are acquired and stored into on-board memory in an image format. The image data can then be transferred into system memory at an optimum rate. The video capture system comprises a host computer, including a video capture board, which is coupled to a video source, such as a video camera. The video source provides digital video data in a first format of a plurality of different possible formats. The video capture board includes a memory controller which receives the digital video data in the first format and selectively provides the digital video data to the buffer memory in an image format. The memory controller includes address generation logic for generating buffer memory addresses for storing the video data to the buffer memory in the image format. The address generation logic is programmable with configuration information corresponding to the first format and uses the configuration information to generate the addresses.
