Abstract

A program selecting system includes a playback device and a server. During playback of a program, the playback device transmits a program identifier for identifying the program, an evaluation of the program by a viewer, and an attribute of the viewer to the server. The server totalizes evaluations of programs according to viewer attribute and stores evaluation totals. When requested by the playback device, the server transmits program identifiers of programs which are highly evaluated by other viewers having similar attributes to the viewer, and evaluation totals of the programs. The playback device displays ranking of the programs based on the received evaluation totals.

a specific attribute transmission unit operable to transmit the specific attribute information;

a program acquisition unit operable to acquire, from the server device, the program identifiers and elapsed time information pieces selected in relation to the specific attribute information, and the evaluation totals corresponding to the selected program identifiers and elapsed time information pieces; and

a display unit operable to display the acquired program identifiers and elapsed time information pieces, in an order based on the acquired evaluation totals.

7. The program selecting system of claim 1 further including a chat server,

wherein each playback device further comprises:

a chat window used to perform a chat about the program being played back; and

a text input device,

if a chat room for the program has not been hosted, the chat server hosts the chat room, and

the evaluation is an amount of conversation made in the chat.

2. A program playback device comprising:

a playback unit operable to play back a program;

a transmitting unit operable to transmit, while the program is being played back, a program identifier for identifying the program, an elapsed time information piece showing an elapsed time from a start of the program, an evaluation of the program by a viewer, and attribute information showing an attribute of the viewer, to an external device that collects program identifiers, elapsed time information pieces, evaluations, and attribute information from a plurality of playback devices including the program playback device;

an acquisition unit operable to acquire, from the external device, program identifiers and elapsed time information pieces that relate to the attribute information, and evaluations corresponding to the program identifiers and elapsed time information pieces that relate to the attribute information; and

a display unit operable to display the acquired program identifiers and elapsed time information pieces, in an order based on the acquired evaluations.

3. The program playback device of claim 2 further comprising:

a recording unit operable to record a program to a storage medium,

wherein if a program identified by any of the acquired program identifiers has already been recorded by the recording unit, the display unit displays, together with the program identifier, information that the program identified by the program identifier has already been recorded.

4. The program playback device of claim 2 further comprising:

a playback instruction unit operable to choose a program identifier and an elapsed time information piece from the display by the display unit, and obtain a playback instruction,

wherein the playback unit starts playing back a program identified by the chosen program identifier, from a point specified by the chosen elapsed time information piece relative to a start of the program.

5. The program playback device of claim 2 further comprising:

an attribute display unit operable to display the attribute information;

an attribute edition unit operable to edit the attribute information displayed by the attribute display unit; and

an edited attribute transmission unit operable to transmit the edited attribute information to the external device,

wherein the acquisition unit acquires, from the external device, program identifiers and elapsed time information pieces that relate to the edited attribute information, and evaluations corresponding to the program identifiers and elapsed time information pieces that relate to the edited attribute information.

6. The program playback device of claim 5,

wherein the attribute display unit quantifies the attribute information and displays the quantified attribute information in a chart.

8. A server device comprising:

an acquisition unit operable to acquire, from each of a plurality of playback devices, a program identifier for identifying a program being played back, an elapsed time information piece showing an elapsed time from a start of the program, an evaluation of the program by a viewer, and attribute information showing an attribute of the viewer;

a storage unit operable to store, for each of a plurality of viewer types based on attributes, evaluation totals in correspondence with program identifiers and elapsed time information pieces, each evaluation total being a result of totalizing evaluations acquired together with a corresponding program identifier and elapsed time information piece;
