Claim One:
1. A method for optimizing a video transmission, in a constrained environment, corresponding to conditions of transmission of video data through a channel with errors or losses, where the throughput is not unlimited and includes a video coder adapted for coding the video data to be transmitted said method comprising determining one or more compression parameters for the video coder considered to transmit said video data at one of a given throughput Di and for a given quality Qi by executing the following steps: defining and using reference charts for said coder considered predicting, for the part of the video sequence undergoing compression, and by means of said reference charts, compression parameters to be used, at least a quantization interval QP, by selecting one of a QP throughput chart representation and a QP PSNR chart representation, which for the targeted range of throughput Di, or of quality Qi, is the closest in distance to said part of the sequence to be compressed, while complying with a given margin; updating, with an iteration, the prediction step to converge on the best choice of parameterization, said iteration comprising at least one compression step and a verification step; and compressing the video data to be transmitted with said parameters.
