Title
(EN) SYSTEM, APPARATUS AND METHOD TO FACILITATE LIVE VIDEO STREAMING
(FR) SYSTÈME, APPAREIL ET PROCÉDÉ DESTINÉS À FACILITER LA LECTURE EN TRANSIT DE VIDÉOS EN DIRECT
Abstract
(EN)
Systems and methods for generating a master video stream from at least two live video streams are provided in this disclosure. The systems include a combination component that combines the live video streams to generate the master video stream. In one aspect, the live video streams can be copies of the same recording that are multicast from different locations according to User Datagram Protocol. The live video streams suffer different errors, such as stream corruption or stream error, due to the transmission. The combination component eliminates the errors in the live video streams due to transmission and creates a substantially error-free master video stream.

Cette invention concerne des systèmes et des procédés permettant de générer un flux de données vidéo principal à partir d'au moins deux flux de données vidéo en direct. Lesdits systèmes comprennent une composante de combinaison qui combine les flux de données vidéo en direct afin de générer le flux de données vidéo principal. Selon un aspect, les flux de données vidéo en direct peuvent être des copies du même enregistrement qui font l'objet d'une multidiffusion à partir de différents emplacements selon le protocole de datagramme utilisateur. Les flux de données vidéo en direct présentent différentes erreurs dues à la transmission, telles qu'une corruption du flux ou une erreur dans le flux. Ladite composante de combinaison élimine les erreurs dans les flux de données vidéo en direct dues à la transmission et crée un flux de données vidéo principal presque dépourvu d'erreurs.
