Contents reproducing system

摘要

A network connects first, second, and third apparatuses. The first apparatus generates a first list of contents represented by data stored therein. The second apparatus generates a second list of contents represented by data stored therein. The first apparatus gets the second list of contents from the second apparatus, and combines the first list of contents and the second list of contents into a third list of contents. The second apparatus gets the first list of contents from the first apparatus, and combines the first list of contents and the second list of contents into a fourth list of contents which is equal to the third list of contents. The third apparatus refers to one of (1) the third list of contents which is generated by the first apparatus and (2) the fourth list of contents which is generated by the second apparatus.
