DATA RELAYING APPARATUS AND ITS PROGRAM, AND DATA RECEPTION APPARATUS AND ITS PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a data relaying apparatus capable of dynamically establishing a most suitable distribution path at the present time without sharing a connection configuration between apparatuses.

SOLUTION: The data relaying apparatus 3 comprises a receiving means of stream distribution request 43 for receiving a stream distribution request from a downstream data reception apparatus 5 or the other data relaying apparatus 3, a transmitting means of stream distribution request 40 for transmitting the stream distribution request to a distribution requesting destination based on priority, and a receiving means of stream distribution request response 41 for receiving a response relating to the stream distribution request transmitted by the a transmitting means of stream distribution request 40. The transmitting means of stream distribution request 40 is characterized in performing retransmission of the stream distribution request to the other distribution request destination by an order of the priority when distribution of stream data is refused in result of response.
