Claim Text:
1. A method for an encoder to process audio data, comprising: obtaining a noise frame of an audio signal; generating a noise low-band signal and a noise high-band signal from the noise frame; encoding the noise low-band signal for a first silence insertion descriptor (SID) using a first discontinuous transmission mechanism; transmitting the encoded noise low-band signal including the first SID using the first discontinuous transmission mechanism; encoding the noise high-band signal for a second SID using a second discontinuous transmission mechanism, wherein a policy for sending the first SID of the first discontinuous transmission mechanism is different from a policy for sending the second SID of the second discontinuous transmission mechanism, or a policy for encoding a first SID of the first discontinuous transmission mechanism is different from a policy for encoding a second SID of the second discontinuous transmission mechanism, and wherein encoding the noise high-band signal comprises:
