Abstract:
A system implements a hybrid coding mode. The hybrid coding mode may implement a transform to decompose an input stream into frequency components. The frequency components may include frequency bands such as those resulting from a wavelet transform. The frequency components may have associated coefficients which may be determined via the transform. The hybrid coding mode may also implement a predictor-based coding mode. A predictor-based coding mode uses a set of values as predictors for another set of values. The hybrid mode may be implemented by using predictor-based coding to code a portion of the coefficients. For example, a coefficient may be used as a predictor for another coefficient of same frequency component. In some implementations, dynamic selection between a hybrid coding mode and a point coding mode may be used.
