Abstract
(EN)
This application provides a media data processing method and apparatus. A media processing device receives a media stream. The media stream includes media data recorded at a plurality of viewpoints. The device obtains metadata information of the media stream. The metadata information includes viewpoint identification information of the viewpoints. The device displays media data of a first viewpoint based on the viewpoint identification information. The device also displays indications of other viewpoints when displaying the media data of the first viewpoint, so that a user of the device can switch to display media data of other viewpoints. In this application, media data corresponding to different viewpoints can be flexibly processed based on viewpoint identification information.

L'invention concerne un procédé et un appareil de traitement de données multimédia. Un dispositif de traitement multimédia reçoit un flux multimédia. Le flux multimédia comprend des données multimédias enregistrées à une pluralité de points de vue. Le dispositif obtient des informations de métadonnées du flux multimédia. Les informations de métadonnées comprennent des informations d'identification de point de vue des points de vue. Le dispositif affiche des données multimédias d'un premier point de vue sur la base des informations d'identification de point de vue. Le dispositif affiche également des indications d'autres points de vue lors de l'affichage des données multimédias du premier point de vue, de telle sorte qu'un utilisateur du dispositif puisse passer à l'affichage des données multimédias d'autres points de vue. Dans cette application, des données multimédia correspondant à différents points de vue peuvent être traitées de manière flexible sur la base d'informations d'identification de point de vue.
