Abstract
A novel system and method of Reduced-Temporal-Resolution Update (RTRU) and quantizing video transform coefficients is provided for use using hybrid coding standards when receiving a frame from within a group of video frames, where the amplitude of the quantization parameter is defined for the quantization of the frame according to a reduced temporal resolution update process; where the amplitude of the quantization parameter for macroblocks in the frame is defined according to a reduced temporal resolution update process; and where a bitstream is composed for transmission and subsequent decoding by a standard compliant decoder.
