A method and apparatus for transmitting video data over a standard personal computer bus optimizes the video data transfer rate of the bus by parsing the video data into appropriately sized and selected blocks. The video data blocks required for display are stored in a first-in first-out register, addressed, and sent over the data bus of the computer. Video data not required for display is discarded. The video data may be addressed to any location in the memory of the computer for display or further processing.

Method and apparatus for transmitting video, data over a computer bus

A computer implemented process for extracting and processing information in a vertical interval of a video signal comprising a plurality of video lines selects a portion of the vertical interval from the video lines as the video lines are coupled to a computer bus, detects information stored in the selected portion, places the detected information on the bus of the computer, processes the detected information according to the portion of the vertical interval from which it is selected, and processes the video lines responsive to the detected information from the vertical interval.
