Abstract:
A stereo sound encoding method and system, for encoding left and right channels of a stereo sound signal, down mix the left and right channels of the stereo sound signal to produce primary and secondary channels and encode the primary and secondary channels. Encoding the primary channel and encoding the secondary channel comprise determining a first bit budget to encode the primary channel and a second bit budget to encode the secondary channel. If the second bit budget is sufficient, the secondary channel is encoded using a four subframes model and, if the second bit budget is insufficient for using the four subframes model, the secondary channel is encoded using a two subframes model.

Claim (Index 15):
A stereo sound encoding system for encoding left and right channels of a stereo sound signal, comprising:\n a down mixer of the left and right channels of the stereo sound signal to produce primary and secondary channels; an encoder of the primary channel and an encoder of the secondary channel; a bit allocation estimator of a first bit budget to encode the primary channel and a second bit budget to encode the secondary channel; and a decision module to select, if the second bit budget is sufficient, encoding of the secondary channel using a four sub-frames model, and, if the second bit budget is insufficient for using the four sub-frames model, encoding of the secondary channel using a two sub-frames model.
