Multimedia tools are becoming an essential means in human interaction, electronic commerce and markets. This increasing amount of information transmitted via communication channels has to be handled in an efficient manner to avoid congestion and delays in the network service. In this work, a new approach to multimedia data transmission and storage is proposed. One of its basic assumptions is that in many situations the multimedia information could be decomposed into basic components or codewords that represent a significant part of the data. To illustrate the capabilities of the proposed approach, a compression system for video streams is developed and tested. The system is based on the observations that in most multimedia systems, building blocks of recent history of the stream can describe present details of the multimedia information. Experimental results indicate a high compression ratio of more than 100:1, obtaining almost lossless visual reproduction with SNR higher than 30 db. Unlike MPEG or the like, the proposed approach can be similarly used also for other components of the multimedia stream. Our conclusion is that memory-based compression could be very efficient in multimedia systems.
