Abstract
A method and apparatus are provided for controlling and balancing a quality ratio between left and right channels of a stereoscopic video sequence. A complexity measure for each of the channels is first determined. Thereafter, a number of bits representing the video sequence is allocated between the channels according to each channel's complexity. The resultant joint rate control allows the bit rates for the two channels to vary according to the complexity measures of their pictures, while the aggregate bit rate is maintained at the channel capacity, which is a constant value.
