Abstract

대역폭 확장을 위한 고대역 부호화 /복호화 방법 및 장치가 개시된다. 고대역 부호화방법은 전대역 엔벨로프에 근거하여 서브밴드별 비트할당정보를 생성하는 단계, 서브밴드별 비트할당정보에 근거하여 고대역에서 엔벨로프 업데이트를 필요로 하는 서브밴드를 결정하는 단계, 및 결정된 서브밴드에 대하여 엔벨로프 업데이트와 관련된 리파인먼트 데이터를 생성하는 단계를 포함한다. 고대역 복호화방법은 전대역 엔벨로프에 근거하여 서브밴드별 비트할당정보를 생성하는 단계, 서브밴드별 비트할당정보에 근거하여 고대역에서 엔벨로프 업데이트를 필요로 하는 서브밴드를 결정하는 단계, 및 결정된 서브밴드에 대하여 엔벨로프 업데이트와 관련된 리파인먼트 데이터를 복호화하여 엔벨로프를 업데이트하는 단계를 포함한다.
