发明名称 Distribution system
摘要 A distribution system 100 includes a transmission device 110 and a reception device 120. The transmission device transmits content data coded with a certain code rate to the reception device. The reception device, while receiving the content data transmitted by the transmission device, stores received data into a storage device and also reproduces content based on the stored data. The distribution system determines a code rate based on a remaining time before reproduction start time from a present moment and an available reproduction time, which is a time available for reproduction of the content based on the stored data. The transmission device changes the code rate of the content data to be transmitted to the determined code rate. The reception device starts reproduction of the content at the reproduction start point.

主权项 1. A distribution system, including a transmission device and a reception device configured to be capable of communicating with each other, the transmission device being equipped with a content transmitting unit for transmitting content data, which is one content coded with any one code rate of a plurality of code rates different from each other, to the reception device, and the reception device being equipped with a content reproducing unit for, while receiving the content data transmitted by the transmission device, storing received data of the content data into a storage device and also reproducing the content based on the stored data, the distribution system, comprising a code rate determining unit for determining the code rate based on a remaining time before reproduction start time set as time at which the reception device starts reproduction of the content from a present moment and based on an available reproduction time, which is a time available for reproducing the content based on the content data stored in the storage device of the reception device, wherein: the content transmitting unit is configured to change the code rate of the content data to be transmitted to the reception device to the determined code rate; and the content reproducing unit is configured to start reproduction of the content at the set reproduction start time.
