Abstract

The class of k-bit delay decodable codes, source codes allowing decoding delay of at most k bits for k ≥ 0, can attain a shorter average codeword length than Huffman codes. This paper discusses the general properties of the class of k-bit delay decodable codes with a finite number of code tables and proves two theorems which enable us to limit the scope of codes to be considered when discussing optimal k-bit delay decodable codes.

<i>k</i>-位延迟可解码码的性质

k位延迟可解码码，即在k≥0时允许最多k位解码延迟的源代码，可以获得比霍夫曼码更短的平均码字长度。本文讨论了具有有限码表的k位延迟可解码码的一般性质，并证明了两个定理，使我们在讨论最优k位延迟可解码码时能够限制所考虑的码的范围。
