Abstract: front page image
(EN)The present invention relates to a method and an apparatus for encoding and decoding spectrum coefficients in the frequency domain. The spectrum encoding method may comprise the steps of: selecting an encoding type on the basis of bit allocation information of respective bands; performing zero encoding with respect to a zero band; and encoding information of selected significant frequency components with respect to respective non-zero bands. The spectrum encoding method enables encoding and decoding of spectrum coefficients which is adaptive to various bit-rates and various sub-band sizes. In addition, a spectrum can be encoded using a TCQ method at a fixed bit rate using a bit-rate control module in a codec that supports multiple rates. Encoding performance of the codec can be maximised by encoding high performance TCQ at a precise target bit rate.
(FR)La présente invention concerne un procédé et un appareil pour coder et décoder des coefficients de spectre dans le domaine des fréquences. Le procédé de codage du spectre peut comprendre les étapes suivantes : sélection d'un type de codage en s'appuyant sur des informations d'attribution de bits des bandes respectives ; réalisation du codage du zéro par rapport à une bande nulle ; et codage des informations des composantes spectrales importantes sélectionnées par rapport aux bandes non nulles respectives. Le procédé de codage du spectre permet un codage et un décodage de coefficients de spectre qui sont adaptatifs à différents débits binaires et différentes tailles de sous-bande. De plus, un spectre peut être codé en utilisant un procédé TCQ à un débit binaire fixe en utilisant un module de commande de débit binaire dans un codec qui prend en charge plusieurs débits. Les performances de codage du codec peuvent être maximisées en codant le TCQ à hautes performances à un débit binaire cible précis.
(KO)본 발명은 주파수 도메인에서 스펙트럼 계수를 부호화 흑은복호학하는 방법 및 장치에 관한 것이다. 스펙트럼 부호화방법은 적어도 각 밴드의 비트할당정보에 근거하여 부호화방식을 선택하는 단계, 제로밴드에 대하여 제로 부호화를 수행하는 단계, 및 각 넌제로밴드에 대하여 선택된 중요주파수성분의 정보를 부호화하는 단계를 포함할 수 있다. 상기 스펙트럼 부호화방법을 통해 다양한 비트율과 다양한 서브밴드의 크기에 적응적인 스펙트럼 계수의 부호화 및 복호화가 가능하다. 또한, 멀티레이트를 지원하는 코덱에서 설계된 비트레이트 제어모듈을 이용하여 고정비트율로 스펙트럼을 TCQ로 부호화 할 수 있다. 이 때, TCQ의 높은 성능을 정확한타겟 비트율로 부호화하여 코덱의 부호화성능을 극대화시킬 수 있다..
