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 29):
The video encoder according to  claim 21 ,\n wherein the frequency converter, the quantizer, the encoding section, the intermediate buffer, the code amount estimation section, the code amount selector, and the rate controller are integrated into a single semiconductor chip in a semiconductor integrated circuit.
