In this chapter we focus on the underlying representations of common forms of
media Audio, Graphics and Video. In the next chapter we focus on compression
techniques as we shortly understand why these data can be large in storage size
(even when compressed).
The topics we consider here are specifically:
- Digital Audio
- Sampling/Digitisation
- Compression (Details of Compression algorithms Next Chapter)
- Graphics/Image Formats
- Digital Video (Basics of Video end of this chapter but more on Didgiatl Video in next
Chapter as it so closely entwined with Compression)
