Abstract: Voice services are provided in a network node of a digital networking system. A service signal is provided to at least one user device. One or more voice packets are received from the at least one user device. The one or more voice packets are processed, and transmitted to one or more destinations determined in the packet processing.

Abstract: Battery life in portable entertainment devices that play fixed-length music or video files (e.g., MP3 music files) is extended by adaptively adjusting the speed of a processor in the device such that only a minimum number of MIPS are performed to playback the music or video files. Slowing the processor clock provides significant savings in power usage. A use profile containing required MIPS for each song may be stored on the device, or use profile information may be inserted into the data stream or embedded within the data file. Power savings occurs on every subsequent replay of the same entertainment data file or data stream by adaptively adjusting the processor clock to the desired speed as determined by the use profile information (plus design margin based on the particular playback device).

Abstract: A system and method, associated with a receiver, for increasing the range or bandwidth of a wireless digital communication network and a receiver incorporating the system or the method. In one embodiment, the system includes: (1) a service class detector configured to determine a service class of a PDU received by the receiver from the wireless digital communication network and (2) a frame check sequence checker coupled to the service class detector and configured to disregard error-checking information in the PDU when the service class indicates that the PDU is a streaming media PDU.
