<p>Arithmetic coding is a form of entropy encoding used in lossless data compression. It differs from other forms of entropy encoding, such as Huffman coding, in that it encodes the entire message into a single number, an arbitrary-precision fraction, representing the current information as a range defined by two numbers.</p> Signup and view all the answers

<p>The main difference is that simple block encoding would require 2 bits per symbol, which is wasteful, while arithmetic coding encodes symbols with equal probabilities more efficiently, using fewer bits per symbol.</p> Signup and view all the answers

<p>The recent family of entropy coders is called asymmetric numeral systems, which allows for faster implementations thanks to directly operating on a single natural number representing the current information.</p> Signup and view all the answers
