Abstract
A video signal pre-coded using hierarchical coding is transmitted over a communication network, the signal being constituted by data distributed into several hierarchical levels. More specifically, a bandwidth of the communication network is periodically estimated over evaluation periods. A set of hierarchical levels is selected for a current evaluation period, where a transmission rate of the data of the selected hierarchical levels is compatible with the bandwidth estimated for a current evaluation period. A change tendency of the bandwidth is estimated for a following evaluation period. Additional data of the video signal to transmit is then determined depending on the estimated change tendency of the bandwidth, and the data of the selected hierarchical levels and the determined additional data is transmitted during the current evaluation period.
