摘要： A system for client initiated authentication comprises a user agent client and a user agent server. The user agent client is operable to communicate a session initiation protocol request. The session initiation protocol request comprises an authenticate header and a require header that comprises a server authentication tag. The user agent server is operable to receive the session initiation protocol request. The user agent server is further operable to communicate a session initiation protocol response in response to the session initiation protocol request. The session initiation protocol response comprises an authorization header having a credential of the user agent server.

摘要： A system and method for maintaining provisioned configuration for an endpoint in a packet switched communications network are disclosed, the communications network utilizing a signalling protocol between the endpoint and at least one gatekeeper. The gatekeeper receives a request from the endpoint, determines the addresses of an assigned gatekeeper and at least one alternate gatekeeper, and transmits the addresses to the endpoint within the signalling protocol. The endpoint sends a message to its assigned gatekeeper, and if the assigned gatekeeper is responsive, the endpoint receives an indication confirming that the Gatekeeper is available. If the assigned gatekeeper is unresponsive, the endpoint registers with an alternate gatekeeper, but periodically sends a polling status request to its assigned gatekeeper, so that when the assigned gatekeeper becomes responsive, the endpoint may then register with its assigned gatekeeper.

摘要： Described herein is a method and system for multiplier optimization. A gate count savings that does not introduce additional quantization error can be achieved with this method and system. By increasing the number of digits in a multiplication result, partial products within a multiplication can be truncated. When the multiplication result is used in a subsequent operation, the gates required for the increased number of digits in the multiplication result can be made less than the gates saved within the multiply.

摘要： An apparatus and method for determining inter-frame motion during compression of digital video data incorporates a computationally efficient hierarchical block-matching motion estimation technique in conjunction with a full-search block-matching approach. In the hierarchical block-matching method, a macroblock is filtered and decimated, and a search area is also filtered and decimated. A block-matching search is performed within the filtered and decimated search area. An augmented block in the original search area that corresponds to the block in the decimated search area that provided the best match with the decimated macroblock is then compared with the original macroblock to determine a motion vector. Operating parameters specify the search range based on the type of frame being processed, i.e. P-frame or B-frame, and, in the case of B-frames, the distance of the B-frame from the reference frame. If the operating parameters specify a search range above an established threshold, the hierarchical block-matching search is performed. If the operating parameters specify a search range equal to or below the established threshold, the full-search block-matching search is performed.
