Abstract: A rate control algorithm for a predictive video encoder is provided to accurately control the coding rate while requiring a small complexity. The algorithm assumes the video encoder to consist of two processors, pre-processor and main processor, and the rate control located in main processor uses prediction cost and residual cost for each picture that are computed in pre-processor. Prediction cost represents the estimated number of bits needed to generate an error image, and residual cost describes the difficulty of encoding the resultant error image. Accurate and simple rate control is made possible by using a new rate model that adapts to the local characteristic of a video sequence, and by targeting to maintain the quantization parameter as constant as possible in a given set of pictures, GOP, instead of the conventional two step approach.

Abstract: A technique is provided for use in a video processing system for selecting between an inter-frame coding mode and an intra-frame coding mode when processing a current portion of a video sequence. The technique includes identifying previously reconstructed samples associated with the current portion from a current frame and a reference frame of the video sequence. Then, a selection is made whether to implement the inter-frame coding technique or the intra-frame coding technique on the current portion based on comparisons associated with the previously reconstructed samples. The technique may be implemented in both a video encoder and a video decoder. As a result, the encoder does not need to transmit coding mode-related overhead information to a corresponding decoder. By way of example, the invention may be implemented in a pixel-based coding system or a block transform-based coding system.
