Abstract
A method and apparatus for coupling a video camera to a host computer, e.g., a personal computer, for transmitting video images therebetween. An embodiment of the present invention provides a method and apparatus for delivering video data to a frame buffer in a memory of the host computer wherein the video image may be stored at other than dword aligned memory addresses in the video frame buffer. In an embodiment of the present invention, byte alignment of video data can be controlled according to three categories: 1) adjustment at the start of a video line; 2) adjustment at the end of a video line; and, 3) stride calculation from the end of one line to the beginning of the next line.
