摘要： A method, apparatus, system, and computer program product for auto-installing an integrated receiver/decoder (IRD) includes issuing an auto-installation command from the IRD to an outdoor unit (ODU) and receiving a plurality of tones from the ODU in response to the auto-installation command, each tone representing a center frequency of available user bands (UBs). The auto-installation also includes acquiring a UB center frequency by the IRD, requesting the ODU to confirm a UB number corresponding to the acquired UB center frequency, and receiving confirmation from the ODU that a UB number corresponds to the acquired UB center frequency. The auto-installation also includes sending an acceptance of the assigned UB number from the IRD to signal the ODU that it may mark the assigned UB as assigned.

摘要： A method, system and computer program for decompressing video data, storing the compressed video data in such a way that random access is possible and the data can be mapped efficiently into existing memory systems and interface protocols. The compression is accomplished via lossless compression using an algorithm optimized for video data. Due to the compressed format, data transmission consumes less bandwidth than using uncompressed data and prevents degradation in the decoded video.

摘要： An outdoor satellite receiving unit (ODU) receives several independent satellite signals, selects two signals with a switch matrix, downconverts the two signals to a bandstacked signal with a high and a low band signal, and outputs the bandstacked signal on the same cable to receiver units. Several satellite signals can be selected in groups of two or more and output to independent receiver units. Signal selecting is performed at the received radio frequency (RF) and bandstacking is performed with a single downconversion step to an intermediate frequency (IF). Channel stacking on the same cable of more than two channels from several satellites can be achieved by using frequency agile downconverters and bandpass filters prior to combining at the IF output. A slow transitioning switch minimizes signal disturbances when switching and maintains input impedance at a constant value.

摘要： A method and an apparatus from such method for designing an integrated circuit (IC) that mitigates the effects of process, voltage, and temperature dependent characteristics on the fabrication of advanced IC's but provides high die yields, lower power usage, and faster circuits. Conventional design process takes into account power supply voltage Vdd as a variable that must be considered in a skewed corner analysis. The disclosure teaches that the IC design process can be substantially simplified by essentially factoring out voltage based variations in corner lot analysis for IC designs that include dynamic voltage scaling circuitry, because each fabricated IC die of an IC design having dynamic voltage scaling can individually adjust the applied supply voltage Vdd within a range to offset local process-induced variations in the performance of that specific IC die.
