The research and studies of compressed digital files is aimed to ease of dealing with communication networks and the Internet, and that by reducing the size of transferred multimedia files, as well as used to increase the security of information transmitted through digital files. The search has been relied on hybridization wavelet transformation and Embedded Zero-Tree Wavelet (EZW) for compression of digital video files , and through the introduction of digital video file to be compressed and then cut up into a series of frames and then analyzing each frame to slide three colorimetric (red, green, and blue ), and then apply the Haar_Wavelet because of its advantage in the multivariate analysis of the image into a number of packets sub that facilitates the process of compression for the purpose of access to the best results in the recovery and that by keeping monuments basic image, interference with Embedded Zero-Tree Wavelet in compression technology on each of the three color slides and through the application of coding and quantization processes and Dominant Pass Function and Subordinate PASS Function. After that process is decompression, and by using a set of tools and comparative examination shows that the results were compatible with the requirements of the research.
