Abstract: A system and method for lossless data compression of byte oriented digital data, including but not exclusively executable program code and related data. This lossless data compression system and method when used to process sets of similar but not identical input data, will generate compressed forms of that data which also have a high degree of similarity. The present invention utilizes an update package generated based on the differences between the compressed forms of data, whereby the update package can be applied to the original compressed form to create the new form. A typical change to create the new form from the original would be when making bug fixes to deployed software.

Abstract: A system and method for the detection, compression, and decompression of previously compressed data that resides in data or files of an unknown data or file format.

Abstract: A method for providing network management using a remote device. The method may include receiving an end-user message from an end-user device configured to communicate with a network management tool and processing the received message to perform a network management function on at least one network component. The end-user device may include one of a plurality of wireless devices, and the network management tool is configurable to communicate with any of the plurality of wireless devices.

Abstract: A system and method are provided for use in maintaining secure communications between a home network and a mobile client when the client roams outside of the home network to a new location.

Abstract: A method for improving lossless image compression by using multiple lossless image compression techniques and adapting the best one to each image. An RGB compressor receives an image file and splits the image into rectangular block types. Different digital image and/or sub-image (block) types are optimally compressed using a compression techniques particularly well-suited for the particular kind of image or block.

Abstract: Video messages are created in a manner that allows transparent delivery over any electronic mail (e-mail) system. The audio and video components of the message are recorded, encoded, and synchronously combined into a video message file. A player is selectively attached to the video message file to create an executable file which can be delivered as a standard binary file over conventional communications networks. To view the received video e-mail, the recipient executes the received file and the attached player automatically plays the video and audio message or the recipient executes the previously installed player which plays the video message.
