摘要

PROBLEM TO BE SOLVED: To reduce a burden of data production while intelligibly expressing relevance between pieces of data managed by a hierarchical structure. SOLUTION: A communication part 201 receives the plurality of pieces of the data managed by the hierarchical structure. The hierarchical structure is defined by use of identification information previously stored in distributed data and next reproduction information for designating the other next reproducible data previously stored in the distributed data. A control part 207 makes a button showing reception of instruction input transiting a reproduction target to the other data belonging to a higher hierarchy than data during reproduction to be displayed on a screen together with a reproduction screen of the data based on the hierarchical structure. The control part 207 reproduces the other data when receiving the instruction input transiting the reproduction target to the other data. COPYRIGHT: (C)2009,JPO&INPIT
