MPEG-D

Known as: ISO/IEC 23003, ISO/IEC 23003-2 
MPEG-D is a group of standards for audio coding formally known as ISO/IEC 23003 - MPEG audio technologies, published since 2007. MPEG-D consists of… Expand

다양한 기능을 가지는 모바일 기기들이 하나로 융합되어 가는 방향으로 기술이 발전함에 따라, 음성 및 오디오 모두에 대해 우수한 음질을 제공하는 부호화 기술에 대한 요구사항이 증대되고 있다. 이와 같은 새로운 부호화 기술에 대한 요구사항에 따라, MPEG에서는 2007년 10월 82차 회의에서 CfP를 시작으로 USAC 표준화를 시작하였고, 2009년 4월 88차 회의에서 WD3까지 완성되었다. MPEG-D USAC 기술은 최신 음성 부호화기인 AMR-WB+와 최신 오디오 부호화기인 HE-AAC V2를 융합한 기술로 입력 신호의 특성에 따라 코어 대역 부호화로 AAC, ACELP, TCX 등 다양한 방법 중 하나를 선택하여 부호화를 수행하고, 고대역 부호화 기술로는 SBR, 스테레오 부호화 기술로는 MPEG-Surround를 이용한다. USAC 기술은 음성과 음악 신호 모두에 대해 모두 우수한 음질을 제공할 수 있으며, 모바일 기기로의 멀티미디어 콘텐츠 다운로드, 디지털 라디오, 모바일 TV 및 오디오 북등에서 응용이 가능하다. 【As mobile devices become multi-functional, and converge into a single platform, there is a strong need for a codec that is able to provide consistent quality for speech and music content MPEG-D USAC standardization activities started at the 82nd MPEG meeting with a CfP and approved WD3 at the 88th MPEG meeting. MPEG-D USAC is converged technology of AMR-WB+ and HE-AAC V2. Specifically, USAC utilizes three core codecs (AAC ACELP and TCX) for low frequency regions, SBR for high frequency regions and the MPEG Surround tool for stereo information. USAC can provide consistent sound quality for both speech and music content and can be applied to various applications such as multi-media download to mobile device Digital radio Mobile TV and audio books.】
