摘要

An information processing apparatus carries out a process using delivery information delivered through a network. Only divisional delivery information used in the process of an n-time speed and acquired through a network by dividing the delivery information when the process is carried out at the n-time speed (where n>1) is acquired. Confirmation information used in confirming whether or not the divisional delivery information thus acquired is normally acquired through the network then is acquired, and the confirmation process of whether or not the divisional delivery information is normally acquired is carried out using the confirmation information. A processor carries out the process of the n-time speed using the divisional delivery information when the divisional delivery information is determined to have been normally acquired.
