Abstract
The main issue this paper addresses is to obtain the information sources characterising the video sequences represented in DWT domain and to discuss their relevance for practical applications. From the statistical point of view, this means to establish whether the DWT coefficients can be approximated by random variables and, if so, to compute the corresponding probability density functions (pdf). The corpus considered in experiments is composed of 10 video sequences, belonging to different movies, each of them about 25 minutes long, DivX coded at a very low rate.
