A method and system for compressing video data in a computer has video processing that is distributed between preprocessing hardware in a video capture/controller card and a central processing unit of the computer. Frames of video data are passed to a motion estimation unit of the preprocessing hardware. This unit generates motion information describing inter-frame changes in the video data. Next, motion-compensated temporal filtering is performed on the frames of video data using the motion information. A video frame processing unit of the controller card, used for processing video data to the monitor, is reused for the temporal filtering of the input video data. Finally, the temporally-filtered video data is passed to the central processing unit, which performs inter-frame and/or intra-frame compression with reference to the motion information. In this way, motion-compensated temporal filtering is performed, thus removing the associated noise without adding to the CPUs processing burden, but the costs associated with dedicated compression hardware are avoided by relying on the video capture capabilities in the video controller card.

An apparatus and method for performing two-pass real time video compression is provided. Tactical decisions such as encoding and quantization values are determined in software, whereas functional execution steps are performed in hardware. By appropriately apportioning the tasks between software and hardware, the benefits of each type of processing are exploited, while minimizing both hardware complexity and data transfer requirements. One key concept that allows the compression unit to operate in real time is that the architecture and pipelining both allow for B frames to be executed out of order. By buffering B frames, two-pass motion estimation techniques can be performed to tailor bit usage to the requirements of the frame, and therefore provide a more appealing output image.
