In recent years broadcasting attracted considerable attention as a promising technique of disseminating information to large number of clients in wireless environment as well as in the web. In this paper, we study different schemes of multiversion broadcast and show that the way broadcast is organized has an impact on performance, as different kind of clients needs different types of data. We identify two basic multiversion organizations, namely Vertical and Horizontal broadcasts, and propose an efficient compression scheme applicable to both. The compression can significantly reduce the size of the broadcast and consequently, the average access time, while it does not require costly decompression. Both organizations and the compression scheme were evaluated using simulation.
