STREAM DATA DISTRIBUTION SYSTEM, RELAY DEVICE AND RECEPTION DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a stream data distribution system allowing reduction of a processing load of a relay device, and capable of preventing generation of reproduction delay in a reception device.

SOLUTION: The relay device 4 extracts an image frame from stream data distributed from a transmission device 2 in timing of an acquisition period Tpull and stores it into a buffer area 16 when receiving information showing the acquisition period Tpull of the data from the reception device 6 in advance, and distributes the image frame stored in the buffer area 16 to the reception device 6 when receiving acquisition requirement of the data from the reception device 6 in the timing of the acquisition period Tpull.
