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 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.
