Patent

CA 2276129

This application invention comprises a TV broadcast system, which using multiplexed and duplex, communication and verification methods, directs and controls from a central continuity studio (I), one or more remote stand alone TV transmitters (IV) to change and/or modify the content of their local broadcast material. Thus it is possible to direct the local broadcast to switch between the general broadcast program or a previously stored (at the remote site) live video. Moreover it is possible to superimpose on the video being broadcast, alphanumeric character and/or image data, which are also previously stored at the remote site (IV).

La présente invention concerne un système de diffusion de télévision qui, en utilisant des procédés communication et de vérification multiplexés et duplex, organise et gère depuis un studio central de continuité (I) un ou plusieurs émetteurs de télévision (IV) se trouvant à distance, de façon qu'ils changent et/ou modifient le contenu de leur matériau de diffusion locale. Ainsi, il est possible d'amener la diffusion locale à commuter entre le programme de diffusion générale ou une vidéo en direct préalablement stockée (au niveau du site à distance). En outre, il est possible d'incruster dans la vidéo en cours de diffusion, des caractères alphanumériques et/ou des images numérisées, qui ont été également préalablement stockés au niveau du site à distance (IV).
