Abstract: Techniques are described for processing one or more input sources. One or more frames are received which are to be combined into a composite result frame. Each of the one or more frames corresponds to one of the input sources. For each of the one or more frames, processing is performed to mathematically combine desired video effects to be applied to each frame for a current frame time. For each frame, a set of control settings including scaling and positioning settings is determined. Another set of control settings used to combine one or more transformed frames is determined. Each of the one or more frames is processed to generate a corresponding one of the transformed frames in accordance with the set of control settings associated with each frame. The one or more transformed frames are combined into the composite result frame in accordance with the other set of control settings.

Abstract: A computer based system for displaying and compressing video including a video capture card with a video compressor and a bus interface circuit that acts as a busmaster and outputs uncompressed video and compressed video to a computer bus for display of the uncompressed video on the computer monitor and storage of the compressed video on a memory of the computer.
