CONTENT TRANSMISSION DEVICE AND CONTENT REPRODUCTION DEVICE

摘要

It is possible to realize streaming reproduction in an environment where the communication speed is changed by a change of a position of a moving body such as in a moving vehicle. A content reproduction device (10) includes: a plurality of communication means (mobile telephone (101), radio LAN communication unit (104)) for receiving a content transmitted in a divided state from a content transmission device via a communication path; a content reconstruction unit (113) having a buffer (1130) for temporarily storing the divided content received by the respective communication means and reconstructing the content accumulated in the buffer (1130); a reproduction unit (114) for reproducing the content reconstructed by the content reconstruction unit (113) with a predetermined bit rate; and a communication control unit (110) for calculating the target transmission speed to be assigned to the content reception of each communication means for each predetermined time according to the empty capacity of the buffer (1130) and the bit rate and transmitting a first request signal including the calculated target transmission speed to the content transmission device via one of the communication means.
