Abstract: A method and apparatus for encoding an image. In one embodiment, the method comprises encoding, using a tiled Cohen-Daubechies-Feauveau (CDF) filter, a plurality of tiles of the image, wherein update step results of one tile edge of a first tile of the plurality of tiles are used as inputs to a predict step of an adjacent tile edge.

Abstract: The present invention enables the transparent bridging of an audio controller over a network between a host PC and a remote user interface system by providing a host module that presents the interface of an audio controller to a system bus of a host computer and a remote module that presents an audio link interface to codecs in a remote system. By bridging the controller at these interfaces, the effects of network delays and data loss can be controlled inside the user's human perception limits without introducing signal timing problems at the two specified interfaces.

Abstract: A method and apparatus for utilizing a bridged peripheral system within a bridged computer system having a host computer and a remote computer. The host computer executes peripheral driver software that initiates at least one communication. The host computer also executes a peripheral emulation that represents a peripheral of the remote client computer, where the at least one communication is processed by the peripheral emulation. In one embodiment, the peripheral is an audio codec.

Abstract: A method and architecture for the extraction of data from or the insertion of data into Synchronous Optical Network (SONET) or Synchronous Digital Hierarchy (SDH) frames is disclosed. The method and architecture provides an interface that permits the time-multiplexed data streams being extracted or inserted to have variable data-rates and no fixed alignment with respect to each other. The extraction and insertion interface accommodates for variable POH data rates and alignment inconsistencies of POH bytes amongst different paths due to floating pointer positions. The interface operates at the lowest possible frequency that can still accommodate the minimum spacing between any two consecutive words of data for a given data stream. In the insertion case, the frequency of operation chosen also allows the pipelining of requests as well as the pipelining of the subsequent associated data in response.
