Patent ID: 8477736

Claim:
A multimedia server comprising: an encoder for generating an encoded signal from a multimedia input signal; a first transceiver that modulates the encoded signal to produce a first radio frequency (RF) signal and that transmits the first RF signal, that includes a packetized video signal, to a client over a first transceiver channel when the first transceiver is in a transceive mode, the first transceiver including: a first channel controller that performs a first channel scan during a quiet time between video packet acknowledgements when the first transceiver is in a scan mode, that determines at least one performance parameter of the first transceiver channel and asserts a low performance signal when the at least one performance parameter compares unfavorably to a performance threshold, and that switches the first transceiver to a selected alternative transceiver channel when the low performance signal is asserted; a second transceiver for modulating the encoded signal to produce a second RF signal and for transmitting the second RF signal over a second transceiver channel when the second transceiver is in a transceive mode, wherein the second transceiver includes: a second channel controller that performs a second channel scan when the second transceiver is in a scan mode and wherein the switch is coupled to the second channel control module, and wherein the second channel scan includes determining at least one performance parameter of a plurality of alternative transceiver channels and selecting the selected alternative transceiver channel of the plurality of alternative transceiver channels; wherein the first transceiver channel is a channel of a broadband wireless access network.
