Abstract: A system, method and computer readable medium for allowing multicast receiving at a user computer coupled to a subnetwork that is coupled to a public data network. The present invention determines if a request to receive a multicast signal has occurred, tests a subnetwork for a first multicasting protocol, if it a request to receive a multicast signal was determined to have occurred, implements the first multicasting protocol, if the result of the test is above a criteria. If the result of the test is below the criteria, the invention tests a subnetwork for a subsequent multicasting protocol and implements the subsequent multicasting protocol, if the Ad result of the test is above the criteria. The testing of a subnetwork for a subsequent multicasting protocol and implementing the subsequent multicasting protocol, is repeated until the result of the test is above the criteria.

Abstract: A system and method for compressing a video image. The system includes an object database and a compression processor coupled to the object database for receiving video image information from a video source. The compression processor includes an image analyzer for determining status of one or more pixels of the video image over time, a shape determiner for determining a shape that defines a group of pixels that are determined to have the same status over a period of time, an object retriever for retrieving an object from the object database that corresponds to the determined shape from a stored set of objects, and a saving component for saving information relating to the selected object and dimensional information of the determined shape.

Abstract: A computer processor implemented video compression method and computer program product for automatically adjusting frame interval during compression of a video signal. The method determines a video motion value from the video signal, determines frame interval according to the determined video motion value, and automatically adjusts the frame interval according to the determined frame interval.
