Advantages of Arithmetic coding:-
- Arithmetic coding is naturally suitable for adaptation strategies.
- Arithmetic coding is close to optimal compression performance for sources with very low entropies.
- It is easy to implement a system with multiple arithmetic codes.
Problems of Arithmetic coding:-
- Unlike Huffman coding, the decoder requires knowledge of the number of symbols to be decoded.
- Transmission of coded data cannot begin until the whole sequence is encoded.
- Infinite precision is required.
