Description

The arithmetic coding is a mathematical compression, based on the coding of a input sequence using a rational number of the unit interval [0,1). In the animation the algorithm is demonstrated and the procedure illustrated using an example, during which the executed commands and values changed by them are highlighted using a different colour. Following the animation of the coding the animation of the decoding is shown, in which the original message is extracted.

HowToUse

For detailed instructions on how to install Animal and run Animal AVs, see: http://www.algoanim.info/Animal2/?q=node/290. Once you have installed the Animal .jar file and downloaded/unpacked the .zip file of Animal animations, you are now ready to run Animal. Run the .jar file to start Animal. Then go to the "Open" menu item, and browse to where you put the animal animations you got in the .zip file. Pick this AV from the list. You can then step through the animation, or use "kiosk mode" to have the steps fed to you at a constant pace.
