Abstract
A signal compression optimization system between a communication network and wireless user equipment advantageously selects an optimized decompressor when feasible for reduced content processing latency and otherwise selects a virtual machine decompressor, such as a Universal Decompressor Virtual Machine (UDVM) that interprets the received decompression bytecode. Since the UDVM is not optimized for any particular decompression algorithm and suffers by the requisite delays associated with analyzing each statement in the bytecode before execution, being able to avoid use of the UDVM whenever possible enhances user experience in presenting wirelessly received signaling messages or media content.
