- Compression doesn't happen on a per block basis. Rather the compression
- algorithm is applied to the incoming data stream and produces a data
- stream itself. Formatting this data into blocks and transmitting them
- happens on a lower processing level that should be (mostly) unrelated to
- the compression scheme itself.
