Abstract

An information processing device includes a display recording list receiver that receives display information for displaying a list of one or more content items from a server through a first connection made based on a first communication mode. Moreover, the information processing device includes: a P2P connection implementation unit that establishes, between a receiving device and the information processing device, a second connection made based on a second communication mode for performing communication between the receiving device and information processing device without passing via the server; a recorded program selector that selects a content item out of the one or more content items based on the display information; and a recorded program receiver that receives the selected content item from the receiving device through the second connection.

Claims

1. A communication system comprising:

a receiving device that stores one or more content items;

a server; and

an information processing device for reproducing the content items,

wherein the information processing device includes;

a display information receiver that receives display information for displaying a content list, which contains a list of the one or more content items, from the server through a first connection made based on a first communication mode;

a communication establishment unit that establishes a second connection between the receiving device and the information processing device, the second connection being made based on a second communication mode for performing communication between the receiving device and the information processing device without passing via the server;

a content selector that selects at least one content item out of the one or more content items based on the display information; and

a content receiver that receives the at least one content item, selected by the content selector, from the receiving device through the second connection established by the communication establishment unit,

wherein after the communication establishment unit starts to establish the second connection between the receiving device and the information processing device and before the second connection is established, the display information receiver receives the display information from the server through the first connection.

2. The communication system according to claim 1, wherein

the server includes:

a content list receiver that receives the content list from the receiving device; and

a display information converter that converts the content list into the display information, and

the display information includes information for controlling an expression format of the content list.

3. The communication system according to claim 2, wherein the one or more content items include a broadcast program recorded by the receiving device.

4. The communication system according to claim 1, wherein the one or more content items include a broadcast program recorded by the receiving device.

5. An information processing device comprising:

a display information receiver that receives display information for displaying a content list, which contains a list of one or more content items, through a first connection made based on a first communication mode;

a communication establishment unit that establishes a second connection made based on a second communication mode different from the first communication mode;

a content selector that selects at least one content item out of the one or more content items based on the display information; and

a content receiver that receives the at least one content item, selected by the content selector, through the second connection established by the communication establishment unit,

wherein after the communication establishment unit starts to establish the second connection between a receiving device and the information processing device and before the second connection is established, the display information receiver receives the display information from a server through the first connection.

6. A communication method in a communication system including a receiving device that stores one or more content items, a server, and an information processing device for reproducing the content items, the communication method comprising:

establishing a second connection, the second connection being made based on a second communication mode for performing communication between the receiving device and the information processing device without passing via the server;

transmitting display information for displaying a content list, which contains a list of the one or more content items, from the server to the information processing device through a first connection, after starting to establish the second connection and before the second connection is established;

selecting at least one content item out of the one or more content items based on the display information; and

transmitting the at least one selected content item from the receiving device to the information processing device through the established second connection.
