Abstract:
A method and system are implemented in a stereo sound signal encoding system for time domain down mixing right and left channels of an input stereo sound signal into primary and secondary channels. Correlation of the primary and secondary channels of previous frames is determined, and an out-of-phase condition of the left and right channels is detected based on the correlation of the primary and secondary channels of the previous frames. The left and right channels are time domain down mixed, as a function of the detection, to produce the primary and secondary channels using a factor β, wherein the factor β determines respective contributions of the left and right channels upon production of the primary and secondary channels.

Claim (Index 11):
A time domain down mixing method as defined in  claim 10 , comprising detection of a special case in which the right and left channels are inverted in phase, wherein quantizing the factor \u03b2 comprises representing the factor \u03b2 with an index transmitted to the decoder, and wherein a given value of the index is used to signal the special case of right and left channels phase inversion.
