Abstract: The disclosure includes a video (including audio) processing system for transmission of a video frame across a network. The system includes a video input mechanism, a motion detection mechanism, and a web cam mechanism. The video input mechanism is configured to receive a first video frame and a second video frame. The motion detection mechanism is configured to compare the first video frame with the second video frame. It is also configured to generate a motion-detected signal if the comparison of the frames deviates from a threshold value. The web cam mechanism is configured to transmit the second video frame if it received the motion detection signal from the motion detection mechanism. The disclosure also includes a method for processing a selected video frame for transmission across a network.

Abstract: A method and apparatus for detecting motion in digitized images involves the use of discrete cosine transforms. Video images are reduced in size to reduce the number of DCT blocks used in the analysis. Similarly, quantization of only portions of the DCT blocks are needed to detect motion between successive video images.

Abstract: The present invention combines features of an executable process with the need for multiple application programs to share a single input device. The present invention provides an executable program implemented as a process that allows multiple applications to communicate with a single input device. This is achieved by loading the input device control executable program as a process. The executable program is a server thus allowing multiple application programs to interface with the same input device. The multi-instance input device control (MIIDC) executable program responds to each application program request as if the input device is open for the calling application program. Each application program is thus enabled to communicate with the input device instance without interrupting the operation of other application programs communicating with the input device. The input device instance keeps track of all the connections to it and multiplexes and resolves conflicting requests.
