Scope Notes

Glossary: Resynchronisation marker resynchronisation markers A special Variable Length Coding binary word inserted to allow re-initialisation of VLC decoding, which is forced by the marker. Reversible Variable Length Coding reversible variable length code reversible variable length codes RVLC VLC allowing backward decoding of the stream, i.e. decoding of a VLC coded binary string starting from the end to the beginning.
