本文提出了一种用于1997年发射的研究土星的卡西尼号航天器的有损编码方案。为了处理特定的时频数据和众多的约束条件，我们的编码算法是基于小波分解相关联的自适应比特分配过程。我们的方法的性能进行了验证，适应科学的评价。
This paper presents a lossy coding scheme designed to be board on the Cassini spacecraft which has been launched in 1997 to study Saturn planet. To deal with specific time-frequency data and numerous constraints, our coding algorithm is based on wavelet decomposition associated to an adaptive bit allocation procedure. The performances of our approach are validated by an adapted scientific evaluation.
