  • Constant bit-rate control in a video coder by way of pre-analysis of a slice of the pictures
    Patent number: 6215820
    Abstract: An algorithm based on a pre-analysis implements an efficient constant bit-rate control with a reduced requirement on a buffer memory capacity. The pre-analysis is on at least one slice (GOS) of the current whole picture, and/or on a mix of information on the pre-analysis of a slice of the preceding picture and on the actual encoding data of the preceding whole picture. The pre-analysis may be carried out by precoding the GOS with a constant reference quantizer or by entropy computation. The local control of the bit-rate is implemented by an integrative-proportional controller.
