Abstract
In an interface connecting a video camera to a host, a method and apparatus for storing video data received from a video camera in video data buffers in the host's memory. The method allows for a large number of video data buffers. Moreover, the video data buffers may be managed by an apparatus other than a processor on the host, thereby offloading the host's processor to perform other tasks. A linked list of commands in memory on the host contain control information, register addresses of registers in the apparatus, and data, which the apparatus utilizes to store received video data in the video data buffers.
