McMillan's inequality proved that Huffman code attains an optimal average code length in a class of
source codes that can be uniquely decodable using a single code tree.
On the other hand, AIFV code can attain shorter average code length than Huffman code if it allows for a 2-bit decoding delay and two code trees.
This paper proves that AIFV code achieves an optimal average code length in a class of source codes allowing for a 2-bit decoding delay and two code trees. |
