VIDEO CODING APPARATUS AND VIDEO CODING METHOD |
摘要 |
<p>A video coding apparatus includes a quantization unit for quantizing a video data; a binarization unit for converting the quantized video data into binary symbol series; an arithmetic coding unit for subjecting the binary symbol series to arithmetic coding; and a quantization control unit estimating a generated data amount on the basis of the output of the binarization unit to control quantization and detecting an actual generated data amount from the output of the arithmetic coding unit to thereby correct the estimated generated data amount.</p> |
