A method for selecting an alternate wireless communication system for a wireless communication device is disclosed. The method comprises using a first radio access technology (RAT) by a wireless communication device when scanning () for an initial wireless communication network (). The wireless communication device further registers () to the initial wireless communication network (). Then, the initial wireless communication network () determines () alternate RAT wireless communication network information for the wireless communication device and sends () the alternate RAT wireless communication network information to the wireless communication device. The wireless communication device receives the alternate RAT wireless communication network information and selects () a first alternate wireless communication network from within the alternate RAT wireless communication network information, scans for the first alternate wireless communication network using an alternate RAT and registers with the first alternate wireless communication network using the alternate RAT.

Method and apparatus for detecting an alternate wireless communication network

Method and apparatus for encoding video is described. In one example, average of motion vectors for each of a plurality of blocks is maintained over a threshold number of inter-coded frames in the video. The running average of motion vectors for each of the plurality of blocks is compared to a threshold value. Each of the plurality of blocks the running average of which does not satisfy the threshold value is encoded using a first quantization parameter. Each of the plurality of blocks the running average of which satisfies the threshold value is encoded using a second quantization parameter. The second quantization parameter results in a coarser quantization of transformed coefficients than the first quantization parameter.

In a cable television system a system for supporting SCU return in FTTB-MDU and FTTC/FTTcab configurations. Fiber, baseband transceiver and networking capabilities are shared with data and voice portions of the system for enabling communication from the SCUs to the HE over a packet based networking system. Return packets/upstream packets are passed into the network upstream channel only when a signal is present for eliminating transmission of upstream traffic that contains no signal for conserving upstream bandwidth.

System for return bandwidth minimization using selective sampling

A telephony system having automatic timing adjustment for diverse routing of HFC systems has a signal stream routing through a signal line loop between a head-end and at least one communication unit , i.e., a cable modem cable access unit (CAU). If a fault occurs within the signal line loop, recognized by the head-end when a short uplink burst from the communication unit does not align within a predetermined timing window based on a value in the database, the head-end will adjust the cycle through predetermined delay parameters, corresponding to various alternate signal line loops made up of redundant signal lines. An information processor is provided at the head-end of the HFC system for automatically adjusting the timing of the signal stream in order to maintain the database determined at the information processor at the head-end . The timing adjustment of the signal stream is communicated between the head-end and the communication units, CAUs

A telephony system having automatic timing adjustment for diverse routing of HFC systems has a signal stream routing through a signal line loop between a head-end and at least one communication unit. If a fault occurs within the signal line loop, recognized by the head-end when a short uplink burst from the communication unit does not align within a predetermined timing window, the head-end will cycle through predetermined delay parameters corresponding to various alternate signal line loops made up of redundant signal lines. Once the predetermined delay parameter corresponding to the current alternate signal line loop is determined, normal operation of the system resumes.
