Abstract:
The present invention provides a video encoder and a method of operating the video encoder to implement high-precision bit rate control by reducing the risk of overflow of an intermediate buffer coupled between a quantizer and an encoding section. The intermediate buffer supplies a selection control signal indicative of whether the amount of stored data is large or small to a selector. If the selection control signal indicates large, the selector outputs an estimated code amount from a code amount estimation section to the rate controller. If the selection control signal indicates small, the selector outputs an actual code amount from the encoding section to the rate controller. The rate controller calculates the quantization scale according to the output of the selector and feedbacks the calculated quantization scale to the quantizer. The quantizer adjusts the quantizer scale.

Claim (Index 28):
The video encoder according to  claim 21 , further comprising:\n a motion vector detector, a motion compensator, a subtractor, an inverse quantizer, an inverse frequency converter, a memory, an intra-prediction section, and a prediction selector, wherein the motion vector detector generates a motion vector from a video signal to be encoded and from a reference image stored in the memory, wherein the motion compensator generates a motion-compensated prediction signal in response to the motion vector generated from the motion vector detector and to the reference signal stored in the memory, wherein the video signal is supplied to one input terminal of the subtractor, the motion-compensated prediction signal generated from the motion compensator is supplied to the other input terminal of the subtractor, and a predictive residual is generated from the output terminal of the subtractor, wherein the predictive residual generated from the output terminal of the subtractor is supplied to the input terminal of the frequency converter as the input signal for the frequency conversion process, wherein the inverse quantizer and the inverse frequency converter perform a local decoding process on the result of the quantization process performed by the quantizer, and the result of the local decoding process is stored in the memory as the reference image, wherein the result of the local decoding process performed by the inverse quantizer and the inverse frequency converter is stored in the memory as an intra-reference image, wherein the video signal is supplied to one input terminal of the intra-prediction section, and the intra-reference image stored in the memory is supplied to the other input terminal of the intra-prediction section so that the intra-prediction section generates an intra-prediction signal about the video signal supplied to the one input terminal, and wherein the prediction selector selects either one of the motion-compensated prediction signal generated from the motion compensator and the intra-prediction signal generated from the intra-prediction section and supplies the selected prediction signal to the other input terminal of the subtractor.
