<p><P>PROBLEM TO BE SOLVED: To provide a tree type distribution system which performs streaming reproduction even when a plurality of pieces of distribution information with different delay times are distributed. <P>SOLUTION: In the tree type distribution system, nodes are connected like a tree using a distribution device as the highest order device, and first distribution information and second distribution information with longer delay time for outputting distribution information in the nodes are transferred from a high order node to a low order node. In the system, the distribution device is a means for starting distribution of the second distribution information before termination of distribution of the first distribution information, when the second distribution information is distributed following the first distribution information, and the node device is a means for, when the first or second distribution information is received, storing the first distribution information and the second distribution information and sequentially reproducing the first or second distribution information, and it detects timing for switching reproduction processing from the first or second distribution information under reproduction to the first or second distribution information which is to be reproduced next and when the timing is detected, starts reproduction processing of the first or second distribution information which is to be reproduced next. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
