Abstract

The present invention provides a terminal capable of receiving information corresponding to scenes of a television broadcast while the television broadcast is being viewed on a television set. A contents delivery system includes the terminal and an output device for receiving and displaying broadcast data delivered from a broadcasting station. The terminal has an identification information acquisition section for acquiring identification information displayed on the screen of the output device, the identification information being included in the broadcast data and changing with time. A relevant information extractor extracts relevant information, relating to contents to be broadcast according to the broadcast data, from the identification information. An output section outputs the relevant information extracted by the relevant information extraction section.

Claims

1. A terminal device comprising:

an identification information acquirer for acquiring identification information output to a display screen of an output device for receiving and displaying broadcast data from a broadcasting station, the identification information being transmitted in the broadcast data and changing over time;

a relevant information extracter for extracting relevant information from the identification information, the relevant information relating to contents to be broadcast according to the broadcast data; and

an output for outputting the relevant information.

2. The terminal device according to claim 1, wherein

the identification information further comprises reference information for gaining access to a contents delivery device for delivering contents comprising more detailed contents relating to broadcast contents;

the terminal device further comprising;

a receiver for receiving the more detailed contents from the contents delivery device based on the reference information; and

the output for outputting the received contents.

3. A terminal device comprising:

an identification information acquirer for acquiring identification information output to a display screen of a device for receiving and displaying broadcast data from a broadcasting station, the identification information being included in the broadcast data and changing over time;

a receiver for receiving contents from a contents delivery device, based on the identification information, the contents including relevant information relating to broadcast contents to be broadcast according to the broadcast data; and

an output for outputting the received contents.

4. The terminal device according to claim 3, wherein the relevant information comprises at least one of information regarding performers and information regarding articles included in the broadcast contents.

5. The terminal device according to claim 3, wherein the received contents comprise a time when the identification information is output to the display screen and the identification information.

6. A contents delivery system comprising a display device for receiving broadcast data delivered from a broadcasting station and for outputting the broadcast data, a contents delivery device for delivering contents, and a terminal;

wherein the terminal comprises;

an identification information acquirer for acquiring identification information output to a display screen of the display device, the identification information being transmitted in the broadcast data and changing over time;

a receiver for accessing the contents delivery device based on the identification information, and for receiving, from the contents delivery device, relevant information relating to contents to be broadcast according to the broadcast data; and

an output for outputting the contents;

wherein the contents delivery device delivers, to the terminal, the contents corresponding to the identification information transmitted from the terminal.

7. The contents delivery system according to claim 6, wherein the identification information and the contents are renewed during broadcasting.

8. An information output method comprising:

acquiring identification information included in receiving broadcast data delivered from a broadcasting station and output to a screen of an output device, the identification information changing over time;

extracting relevant information from the acquired identification information, the relevant information relating to contents to be broadcast according to the broadcast data; and

outputting the extracted relevant information.

9. An information output method comprising:

acquiring identification information output to a display screen of an output device that receives and displays broadcast data from a broadcasting station, the identification information being included in the broadcast data and changing over time;

accessing a contents delivery device based on the acquired identification information and for receiving, from the contents delivery device, contents including relevant information relating to contents to be broadcast according to the broadcast data; and

outputting the received contents.

10. A computer readable medium for storing a computer program that outputs identification information, the computer readable medium comprising:

an acquiring code segment that acquires identification information output to a display screen of an output device that receives and displays broadcast data delivered from a broadcasting station identification information being included in the broadcast data and changing with time;

an extracting code segment that extracts relevant from the acquired identification information, the relevant information relating to contents to be broadcast according to the broadcast data; and

an outputting code segment that outputs the extracted relevant information.

11. A computer readable medium for storing a computer program that outputs identification information, the computer readable medium comprising:

an acquiring code segment that acquires identification information output to a display screen of an output device that receives and displays broadcast data from a broadcasting station, the identification information being included in the broadcast data and changing with time;

an accessing code segment that accesses a contents delivery device based on the acquired identification information and receives, from the contents delivery device, relevant information relating to contents to be broadcast according to the broadcast data; and

an outputting code segment that outputs the relevant information.
