ORTHOGONAL TRANSFORM CODING APPARATUS |
摘要 |
<p>In an orthogonal transform coding apparatus for performing high efficiency coding using orthogonal transformation, a plurality of quantizers are provided, the coded data amount of said plurality of quantizers are respectively calculated, an optimum quantizer to make the data amount less than a specific value is selected to quantize the coded data amount, and the quantized values are encoded in the variable-length form and transmitted. <IMAGE></p> |
