Data Compression

← Back to Domain-Specific Abstractions by Domain

3 domain-specific abstractions whose origin domain is Data Compression.

  • Set redundancy compression — Compression that exploits shared structure across a collection of related data objects rather than encoding each object independently.
  • Variable bitrate — An encoding mode that varies the number of bits assigned per time segment so complex content receives more data and simple content less at a targeted quality or average rate.
  • VCDIFF — A standardized delta-encoding format expressing a target byte sequence through ADD, COPY and RUN instructions relative to source data.
