Title (EN) VIDEO QUALITY CONTROL
(FR) RÉGLAGE DE QUALITÉ VIDÉO
(KO) 비디오 품질 제어
Abstract:
(EN) A technique for video quality control is provided. A quality control method according to embodiments of the present invention can provide videos having a plurality of qualities by controlling, without transcoding the provided video, the quality of the video through a multiplexing or muxing scheme for frames of the video.
(FR) La présente invention concerne une technique de réglage de qualité vidéo. Un procédé de réglage de qualité selon des modes de réalisation de la présente invention peut fournir des vidéos ayant une pluralité de qualités en réglant, sans transcoder la vidéo fournie, la qualité de la vidéo par l'intermédiaire d'un schéma de multiplexage pour des trames de la vidéo.
(KO) 비디오 품질 제어를 위한 기술을 제공한다. 본 발명의 실시예들에 따른 품질 제어 방법은, 제공되는 비디오에 대한 트랜스코딩 없이, 비디오의 프레임들에 대한 멀티플렉싱(multiplexing, 또는 먹싱(muxing)) 기법을 통해 비디오의 품질을 제어하여 다수의 품질을 갖는 비디오들을 제공할 수 있다.
