Claim One:
1. A method for optimizing a video transmission in a constrained environment, video data being transmitted through a channel with errors or losses, throughput of the data transmission channel being finite, wherein a video coder is configured to code the video data to be transmitted, said method comprising: determining one or more compression parameters for the video coder that transmits said video data at a predetermined throughput Di and a predetermined quality Qi by: defining reference charts for said video coder based on reference video data, the reference video data being different from the video data to be transmitted, the reference charts comprising a QP throughput chart representation and a QP peak signal-to-noise ratio chart representation; predicting, for part of the video data undergoing compression and based on said reference charts, compression parameters, the compression parameters comprising a quantization interval QP based on one of the QP throughput chart representation and the QP peak signal-to-noise ratio chart representation, and a targeted range of throughput Di or quality Qi, closest in distance to said part of the video data to be compressed, while complying with a given margin; updating the predicting to converge on optimized compression parameters, said updating comprising compressing and verifying the part of the video data undergoing compression; and compressing the video data to be transmitted based on said determined compression parameters.
