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 36):
The method according to  claim 33 ,\n wherein the encoding section includes an exponential-Golomb coding section, a variable-length coding processor, and an arithmetic coding processor, wherein the exponential-Golomb coding section generates an exponential-Golomb code by encoding a syntax element to be encoded, the exponential-Golomb code including a prefix, a separator, and a suffix, wherein the variable-length coding processor performs a zigzag scan to convert the result of the frequency conversion process performed by the frequency converter, which is quantized by the quantizer, into a one-dimensional vector, and then performs the encoding process based on the variable-length coding method, wherein the arithmetic coding processor includes a binarizer, a binary arithmetic coding section, and a context calculator, wherein the binarizer generates a binary signal from a multivalued input signal, the generated binary signal being encoded into an encoded bit stream by the binary arithmetic coding section, wherein the context calculator dynamically calculates and updates an event probability model for the binary signal in accordance with the condition of a neighboring symbol, the event probability model being an encoding target symbol, and wherein the binary arithmetic coding section encodes the binary signal into an encoded bit stream in accordance with the event probability model calculated and updated by the context calculator.
