Distribution system

A distribution method applied to a distribution system including a transmission device and a reception device configured to be capable of communicating with each other, the distribution method comprising:

• 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, by the transmission device;
• 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, by the reception device;
• 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;
• changing the code rate of the content data to be transmitted to the reception device to the determined code rate, by the transmission device;
• and
• starting reproduction of the content at the set reproduction start time, by the reception device.

A reception device configured to be capable of communicating with a transmission device, the reception device comprising:

• a content reproducing unit for, while receiving content data, which is one content coded with any one code rate of a plurality of code rates different from each other and is 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;
• and
• a code rate determining unit for determining the code rate based on a remaining time before reproduction start time set as time to start 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,
• wherein the content reproducing unit is configured to receive content data coded with the determined code rate and start reproduction of the content at the set reproduction start time.

A non-transitory computer-readable storage medium that stores a program comprising instructions for causing a reception device configured to be capable of communicating with a transmission device to realize:

• a content reproducing unit for, while receiving content data, which is one content coded with any one code rate of a plurality of code rates different from each other and is 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;
• and
• 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 reproducing unit is configured to receive content data coded with the determined code rate and start reproduction of the content at the set reproduction start time.

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 means 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 means 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 means 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 means 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 means is configured to start reproduction of the content at the set reproduction start time.

A reception device configured to be capable of communicating with a transmission device, the reception device comprising:

• a content reproducing means for, while receiving content data, which is one content coded with any one code rate of a plurality of code rates different from each other and is 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;
• and
• a code rate determining means for determining the code rate based on a remaining time before reproduction start time set as time to start 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,
• wherein the content reproducing means is configured to receive content data coded with the determined code rate and start reproduction of the content at the set reproduction start time.
