Abstract
A multimedia server includes a first transceiver that modulates a data signal to produce a first radio frequency (RF) signal and that transmits the first RF signal to a client over a first transceiver channel when the first transceiver is in a transceive mode. The first transceiver includes a first channel control that performs a first channel scan 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.
Claims20
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.
A multimedia server comprising:
- a first transceiver that modulates a data signal to produce a first radio frequency (RF) signal and that transmits the first RF 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 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 data 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, the second transceiver including:
- a second channel controller that performs a second channel scan when the second transceiver is in a scan mode, 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.
A method for use in a transceiver that includes a first transceiver module and a second transceiver module, wherein the first transceiver module modulates an encoded signal to produce a first radio frequency (RF) signal that includes a packetized video signal and that transmits the first RF signal to a client module over a first transceiver channel when the first transceiver module is in a transceive mode, the method comprising:
- performing a first channel scan via the second transceiver module to identify a selected alternative transceiver channel via the second transceiver module when the first transceiver module is in a transceiver mode and the second transceiver is in a scan mode;
- determining at least one performance parameter of the first transceiver channel;
- asserting a low performance signal when the at least one performance parameter compares unfavorably to a performance threshold;
- and
- switching the first transceiver module to the selected alternative transceiver channel when the low performance signal is asserted.
