Abstract:
1. A device comprising: an audio information processor to receive a first audio stream encoded according to a first protocol by a remote network processing device and to receive a first comfort noise information to indicate a level of background noise available for presentation during silence periods associated with the first audio stream, where the audio information processor is configured to decode the first audio stream according to the first protocol, and where the audio information processor is configured to encode the decoded first audio stream into a second audio stream according to a second protocol; a voice activity detector to detect content spurts in the second audio stream; a comfort noise generator to generate a second comfort noise information from the second audio stream, wherein the second comfort noise information is transmitted with the second audio stream; and a background noise translator to convert the first comfort noise information received with the first audio stream into a third comfort noise information encoded in a format compatible with the second protocol, wherein the device transmits both the second audio stream and the third comfort noise information on separate streams.
