<p><P>PROBLEM TO BE SOLVED: To add same display time to frames of a plurality of pieces of content data which are to be synchronously displayed when the plurality of pieces of content data are distributed by different transmission routes. <P>SOLUTION: A transmission device 3a adds a time stamp to the frame of content data received from a production apparatus 1a by using a system clock, and distributes data to a receiver 7. The transmission device 3a registers corresponding information showing absolute time which the production apparatus 1a adds to the frame and the time stamp which the own device adds to the frame with a clock corresponding information distribution server 5. A transmission device 3b acquires the corresponding information from the clock corresponding information distribution server 5. The transmission device 3b calculates time obtained by adding time being a difference between the absolute time which a production apparatus 1b adds to the frame and absolute time which the corresponding information shows to the time of the time stamp which the corresponding information shows, adds the time stamp of the calculated time to the frame of the content data received from the production apparatus 1b to distribute the data to the receiver 7. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
