Transfer apparatus, transfer network system, and transfer method

摘要

When data is disclosed to a plurality of users by using a transfer network and a transfer apparatus, data disclosure time control which cannot be adversely affected by the users is performed to reduce the difference in data disclosure time among the users. A transfer network system includes a distribution server serving 110 as a data-distribution-source transfer apparatus, and a network terminal 120 connected to distribution-destination user equipment 130. The distribution server 110 and the network terminal 120 each have a time keeping function 1100, 1200 and a time synchronization function for matching the time of the time keeping function 1100, 1200 with a master clock 50. The distribution server 110 sends in advance disclosure data and disclosure time to the network terminal 120. When the time of the time keeping function 1200 of the network terminal matches the disclosure time, the network terminal 120 sends the disclosure data to the user equipment 130.
