without compression delivery is virtually impossible
learning objectives
After reading this chapter you should be able to demonstrate the necessity of compression, to discuss criteria for the selection of codecs and mention some of the alternatives, to characterize the MPEG-4 and SMIL standards, to explain the difference between MPEG-4 and MPEG-2, and to speculate about the feasibility of a semantic multimedia web.
Without compression and decompression, digital information delivery would be virtually impossible. In this chapter we will take a more detailed look at compression and decompression. It contains the information that you may possibly need to decide on a suitable compression and decompression scheme (codec) for your future multimedia productions.
We will also discuss the standards that may govern the future (multimedia) Web, including MPEG-4, SMIL and RM3D. We will explore to what extent these standards allow us to realize the optimal multimedia platform, that is one that embodies digital convergence in its full potential. Finally, we will investigate how these ideas may ultimately lead to a (multimedia) semantic web.

the artwork
Both the costume designs and theatre scene designs of
the russian avantgarde movement are expressionist
in nature.
Yet, they show humanity and are in their own way very humorous.
The dance animation by Erica Russell, using
basic shapes and rhythms to express the movement of dance,
is to some extent both solemn and equally humorous.
The animations by Joan Gratch use morphing,
to transform wellknown artworks into other equally
wellknown artworks.
