Chapter 7 Data Compression
In comparison to the text medium, video frames have high storage requirements. Audio and particularly video pose even greater demands in this regard. The data rates needed to process and send continuous media are also considerable. This chapter thus covers the efficient compression of audio and video, which will be explained first in theory and subsequently in terms of compression standards.
7.1 Storage Space
Uncompressed graphics, audio, and video data require substantial storage capacity, which is not possible in the case of uncompressed video data, even given today’s CD and DVD technology. The same is true for multimedia communications. Data transfer of uncompressed video data over digital networks requires that ...
