Arithmetic Coding } Example I (cont.) - En<strong>coding</strong>: any value within the subinterval [0.21360, 0.21600) will now be a well-defined identifier of the string “abcd” - "0.00110111" will be the shortest binary representation of the subinterval Prof. Dr. Paul Müller, University of Kaiserslautern 26
Arithmetic Coding } Example I (cont.) - De<strong>coding</strong>: "0.00110111" resp. 0.21484375 - receiver can rebuild the subinterval development but: code is member of any further subinterval of [0.21360, 0.21600) => extra symbol necessary to mark end of string Prof. Dr. Paul Müller, University of Kaiserslautern 27
