Abstract:
(EN) A video service transmission method and device in the technical field of communications. Data in a video data frame may be shunted into at least two sub-streams according to a mapping relationship between the importance of the data and the sub-stream, and data on the sub-streams is mapped to carriers corresponding to the sub-streams for transmission according to a port number corresponding to the sub-stream. Since a network can use different processing methods for data on different carriers, the video service transmission method and device can give priority to ensuring the reliable transmission of a video data frame with high importance, thereby enhancing the service experience of a video user when transmission resources are limited.
(FR) L'invention concerne un procédé et un dispositif de transmission de service de vidéo se rapportant au domaine technique des communications. Des données dans une trame de données de vidéo peuvent être dérivées dans au moins deux sous-flux selon une relation de mappage entre l'importance des données et le sous-flux, et des données sur les sous-flux sont mappées sur des porteuses correspondant aux sous-flux pour une transmission selon un numéro de port correspondant au sous-flux. Comme un réseau peut utiliser différents procédés de traitement pour des données sur différentes porteuses, le procédé et le dispositif de transmission de service de vidéo peuvent donner la priorité à l'assurance de la transmission fiable d'une trame de données de vidéo avec une importance élevée, ce qui améliore l'expérience de service d'un utilisateur de vidéo lorsque des ressources de transmission sont limitées.
(ZH) 通信技术领域中的一种视频业务的传输方法和装置,可以根据数据的重要性与子流的映射关系,将视频数据帧中的数据分流到至少两个子流上,并根据子流对应的端口号,将子流上的数据映射到与子流对应的承载上进行传输。由于网络能够对不同承载上的数据采用不同的处理方法,因此通过上述视频业务的传输方法和装置能够优先保证重要性高的视频数据帧的可靠传输,从而在传输资源受限场景下提升视频用户的业务体验。
