Encoding apparatus and encoding method |
摘要 |
<p>It is possible to provide an encoding device and an encoding method capable of realizing encoding with a very small information amount and a very small calculation amount when encoding higher-band spectrum data according to lower-band spectrum data in a wide-band signal. The device and the method can obtain a high-quality decoded signal even if a large quantization distortion is caused in the lower-band spectrum data. In this device, when encoding higher-band spectrum data in a signal to be encoded, according to lower-band spectrum data in the signal, only for a part (a head portion) of the higher-band spectrum data, the lower-band spectrum data after being quantized is subjected to approximate partial search and higher-band spectrum data is generated according to the search result.</p> |
