Title
(EN) SYSTEM AND METHOD FOR DYNAMIC BITRATE SWITCHING OF MEDIA STREAMS IN A MEDIA BROADCAST PRODUCTION
(FR) SYSTÈME ET PROCÉDÉ DE CHANGEMENT DE DÉBIT BINAIRE DYNAMIQUE DE FLUX MULTIMÉDIAS DANS UNE PRODUCTION DE DIFFUSION MULTIMÉDIA
Abstract
(EN) A system and method is provided for reducing the bandwidth for media broadcast production. The system includes a plurality of content providing devices and a remote production system. Each of the content providing devices has a corresponding variable encoder. The remote production system transmits control signals to the variable encoders, controlling them to use a high-fidelity encoding method or a compressed encoding method. The remote production system controls the variable encoders such that a media feed being included in a media production is encoded using the high-fidelity encoding method, and some or all of the other media streams are encoded using the compressed encoding method.
(FR) L'invention concerne un système et un procédé pour réduire la largeur de bande pour la production de diffusion multimédia. Le système comprend une pluralité de dispositifs de fourniture de contenu et un système de production à distance. Chacun des dispositifs de fourniture de contenu comporte un encodeur variable correspondant. Le système de production à distance transmet des signaux de commande aux encodeurs variables, les commandant d'utiliser un procédé d'encodage à haute fidélité ou un procédé d'encodage compressé. Le système de production à distance commande les encodeurs variables de sorte qu'un flux multimédia qui est inclus dans une production multimédia soit encodé en utilisant le procédé d'encodage à haute fidélité, et certains ou tous les autres flux multimédias sont encodés en utilisant le procédé d'encodage compressé.
