Patent number: 
181148 (2013-05-31)
Strategic Thrust: 
With a bit amount constraint for a period, the proposed invention enables an optimal quality of scalable audio for that period by truncating the each audio frame according to a pre-trained bitrate table. This can be applied in adaptive streaming, where the quality of the streaming audio is adaptive to the bandwidth available.
