(EN) METHOD AND DEVICE FOR TRANSMITTING AND RECEIVING VIDEO
(FR) PROCÉDÉ ET DISPOSITIF DE TRANSMISSION ET DE RÉCEPTION D'UNE VIDÉO
(ZH) 一种视频传输、接收方法及装置
Abstract
(EN) Disclosed is a method for transmitting a video, which is used for increasing video transmission and receiving quality. The method comprises: generating multiple layers of video streams; in accordance with an obtained first distortion value, obtaining a corresponding first antennae/video matching matrix; separately dispatching each layer of video streams to respective antennae in accordance with the first antennae/video matching matrix; and transmitting same in accordance with the dispatched video streams. Also disclosed are a device for achieving the method, and a method and device for receiving a video.
(FR) L'invention concerne un procédé de transmission d'une vidéo, qui est utilisé pour augmenter la qualité de transmission et de réception de vidéo. Le procédé consiste à : générer de multiples couches de flux vidéo ; conformément à une première valeur de distorsion obtenue, obtenir une première matrice de mise en correspondance d'antennes/vidéos correspondante ; répartir séparément chaque couche de flux vidéo vers des antennes respectives conformément à la première matrice de mise en correspondance d'antennes/vidéos ; et transmettre celle-ci conformément aux flux vidéo répartis. L'invention concerne également un dispositif pour accomplir le procédé, et un procédé et un dispositif pour recevoir une vidéo.
(ZH) 本发明公开了一种视频传输方法,用于提高视频传输及接收的质量。所述方法包括:生成多层视频流;根据获得的第一失真值获得与其对应的第一天线-视频匹配矩阵;根据所述第一天线-视频匹配矩阵将各层所述视频流分别调度到相应的天线上;根据调度后的视频流进行传输。本发明还公开了用于实现所述方法的装置,及一种视频接收方法及装置。
