Abstract (in Japanese) (See Japanese page) 
(in English) Using the one-to-one correspondence between binary AIFV codes and Schröder paths, Sumigawa and Yamamoto gave a method to enumerate all code trees used in the class of binary AIFV codes. They also proposed a coding scheme of each code tree based on the enumeration. In this paper, we generalize Sumigawa and Yamamoto’s method to the case of binary AIFV-m codes and also describe the generating function to enumerate all code trees used in the class of binary AIFV-m codes.
