At least one camera station (1, 2), which is usually mobile, is provided in order to generate television picture signals. These picture signals are coded in coded digital form so as to produce a coded digital signal at output (62) whose bit rate can be selectively varied. The camera station (1) is associated with at least one mobile telephony channel (41, 42, ... , 4n) which can be selectively activated in order to provide a transmission capacity which is available at that moment. The coded signal is transmitted, selectively adapting its bit rate to the transmission capacity available at that moment. The number of mobile telephony channels (41, 42, ... , 4n) that can be activated can also be selectively increased in order to increase available transmission capacity.
On dispose ici d'au moins une station à caméra (1, 2), généralement mobile, pour produire des signaux d'image de télévision. Ces signaux d'image sont codés en format numérique codé de façon à donner en sortie (62) un signal numérique codé au débit binaire sélectivement modifiable. La station à caméra (1) est associée à au moins un canal de téléphonie mobile (41, 42, ... , 4n) s'activant sélectivement de façon à donner une capacité de transmission disponible à ce moment. Le signal codé est transmis, adaptant sélectivement son débit binaire à la capacité de transmission disponible à ce moment. Le nombre de canaux de téléphonie mobile (41, 42, ... , 4n) qu'il est possible d'activer peut également être sélectivement augmenté de façon à accroître la capacité de transmission disponible.
