Delivery control device and delivery control method for content delivery according to ABR delivery method

A delivery control device, which is installed in repeater equipment interposed between a content delivery server device and a client device so as to repeat delivered contents, controls delivery speed for contents by adopting pacing delivery depending on delayed conditions of networks and the operating condition of the client device according to the ABR (Adaptive Bit Rate) delivery method. The delivery control device includes a delivery speed calculation part configured to calculate real delivery speed for sequentially delivering the divided files, which are produced by dividing file data representing contents to be delivered to a client device, in an order of reproducing contents, and a delivery speed determination part configured to determine delivery speed for the divided files based on the real delivery speed calculated by the delivery speed calculation part, the presumed delivery speed determined in advance, and predetermined thresholds relating to intervals of receiving the divided files.
