METHOD AND APPARATUS FOR ENCODING BACKGROUND NOISE INFORMATION Russian patent published in 2012 - IPC H04B1/66

Abstract RU 2440674 C1

FIELD: information technology.

SUBSTANCE: method provides such a design of the encoder in a speech codec that, after a predetermined idle time (standby period), it recalculates average energy and an autocorrelation function. Administrative centres in the network inform the encoder on the idle time set in the data transmission network.

EFFECT: improved implementation of discontinuous transmission in scalable speech codecs.
