1. A method comprising:
- defining an encoding rate for encoding a set of frames of digital multimedia data over a period of time;
encoding the set of frames at a reduced encoding rate over the period of time such that encoding the set of frames at the reduced encoding rate defines one or more null intervals when data associated with the set of frames is not present during the period of time, wherein the one or more null intervals are defined to correspond to one or more transmitter quieting intervals during which a transmitter refrains from transmitting any data;
transmitting the encoded set of frames via the transmitter; and
blanking the transmitter during the transmitter quieting intervals corresponding to the one or more null intervals, wherein blanking the transmitter during the one or more null intervals comprises refraining from transmitting data via the transmitter during the one or more null intervals,wherein the one or more null intervals are not less than six milliseconds to provide a sufficient time for reliable spectrum sensing to be performed.

Abstract
A method includes defining an encoding rate for encoding a set of frames of multimedia data over a period of time, encoding the set of frames at a reduced encoding rate over the period of time such that encoding the set of frames at the reduced encoding rate defines one or more null intervals when data associated with the set of frames is not present during the period of time, transmitting the encoded set of frames via a transmitter, and blanking the transmitter during the one or more null intervals.

21. A device comprising:
-
a multimedia encoding unit that defines an encoding rate for encoding a set of frames of digital multimedia data over a period of time, and encodes the set of frames at a reduced encoding rate over the period of time such that encoding the set of frames at the reduced encoding rate defines one or more null intervals when data associated with the set of frames is not present during the period of time, wherein the one or more null intervals are defined to correspond to one or more transmitter quieting intervals during which a transmitter refrains from transmitting any data, and the transmitter that transmits the encoded set of frames and blanks during the transmitter quieting intervals corresponding to the one or more null intervals, wherein to blank during the one or more null intervals, the transmitter refrains from transmitting data via the transmitter during the one or more null intervals, wherein the one or more null intervals are not less than six milliseconds to provide a sufficient time for reliable spectrum sensing to be performed. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40)

41. A device comprising:
-
means for defining an encoding rate for encoding a set of frames of digital multimedia data over a period of time; means for encoding the set of frames at a reduced encoding rate over the period of time such that encoding the set of frames at the reduced encoding rate defines one or more null intervals when data associated with the set of frames is not present during the period of time, wherein the one or more null intervals are defined to correspond to one or more transmitter quieting intervals during which a transmitter refrains from transmitting any data; means for transmitting the encoded set of frames via the transmitter; and means for blanking the means for transmitting during the transmitter quieting intervals corresponding the one or more null intervals, wherein the means for blanking the means for transmitting during the one or more null intervals comprises means for refraining from transmitting data via the transmitter during the one or more null intervals, wherein the one or more null intervals are not less than six milliseconds to provide a sufficient time for reliable spectrum sensing to be performed. - View Dependent Claims (42)

43. A non-transitory computer-readable storage medium comprising instructions that upon execution cause one or more processor to:
-
define an encoding rate for encoding a set of frames of digital multimedia data over a period of time; encode the set of frames at a reduced encoding rate over the period of time such that encoding the set of frames at the reduced encoding rate defines one or more null intervals when data associated with the set of frames is not present during the period of time, wherein the one or more null intervals are defined to correspond to one or more transmitter quieting intervals during which a transmitter refrains from transmitting any data; transmit the encoded set of frames via the transmitter; and blank the transmitter during the transmitter quieting intervals corresponding to the one or more null intervals, wherein the instructions that cause the processor to blank the transmitter during the one or more null intervals further cause the processor to refrain from transmitting data via the transmitter during the one or more null intervals, wherein the one or more null intervals are not less than six milliseconds to provide a sufficient time for reliable spectrum sensing to be performed. - View Dependent Claims (44)
