Method for providing television coverage, associated television camera station, receiving station and system

摘要

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.
