Abstract: A system and method for compressing data, including image data (204). The image data (204) is formed by a pixel array, the pixel array having target pixels (206) and prior pixels (206), each prior pixel being located in a position within the pixel array prior to each of the targeted pixels. The method of the present invention includes compressing the image data (204) to obtain a compressed image. In the compression step, the pixel array is traversed according to a predetermined non-linear two-dimensional traversing pattern (206). A  longest matching prior pixel string (208, 210), if any, is located for each string of target pixels having a string of matching prior pixels. If no matching prior pixel is found for a target pixel, each such target pixel is characterized as an unmatched pixel (212). Finally, the compressed image is encoded (412) and may be either transmitted or stored (416).

Abstract: A protocol interface gateway (84) connects a telecommunication system emulator (72) to a communications network (79). The gateway (84) receives signals from the network (79) and sends signals to the network that are formatted in a network protocol. The gateway converts signals received from the network into instructions in emulator code, and sends the instructions in emulator code to the emulator (72) for processing. The emulator executes code in blocks of application software (85) utilized in a target telecommunictions node. The gateway then receives the processed instructions in emulator code from the emulator, converts the processed instructions into signals formatted in the network protocol, and sends the signals to the communications network (79). The protocol interface gateway (84) utilizes a UNIX socket (83) that replaces Open Systems Interconnection (OSI) layers (1 and 2) of the network protocol to send and receive the signals from the network.
