摘要

When acquisition processing of content information starts, a terminal apparatus executes acquisition permission determination processing of content information where permission probability is increased along with a lapse of time from starting of the acquisition processing of the content information for every predetermined period. When a result of the determination processing allows the acquisition of the content information, the terminal apparatus acquires the content information from another terminal apparatus.
