Abstract

Video recognition processing on video signals input from an outside is performed. Hence, video reception device which is configured to transmit and receive data through communication network includes input unit, video extraction unit, video recognition region setting unit, control unit and additional information display control unit. The video recognition region setting unit sets a video recognition region to a partial video based on feature information indicating features of video signals input from an outside. The additional information display control unit generates content recognition information in the video recognition region of the partial video. The control unit performs control of requesting video recognition device to perform video recognition processing on this content recognition information.

Claims

1. A video reception device configured to transmit and receive data through a communication network, the video reception device comprising:

an input unit configured to receive an input of a video signal, and content related information including feature information indicating a feature of the video signal;

a video extraction unit configured to extract a partial video for video recognition processing, from the video signal;

a video recognition region setting unit configured to set a video recognition region to the partial video based on the feature information;

a control unit configured to perform control of transmitting content recognition information to a video recognition device connected to the communication network so as to request the video recognition device to perform the video recognition processing, obtaining a result of the video recognition processing from the video recognition device, and obtaining additional information based on the result of the video recognition processing from an additional information distribution device connected to the communication network; and

an additional information display control unit configured to generate the content recognition information in the video recognition region of the partial video.

2. The video reception device according to claim 1, further comprising:

a displaying unit configured to display a video obtained by superimposing the additional information on the video signal.

3. The video reception device according to claim 1,

wherein the additional information display control unit is configured to perform control of superimposing the additional information on the video recognition region of the video signal.

4. The video reception device according to claim 1,

wherein the video recognition region setting unit is configured to instruct the control unit to output a signal for requesting the content related information when not receiving the content related information.

5. The video reception device according to claim 1,

wherein the video recognition region setting unit is configured to, when the content related information includes the feature information related to superimposing information, set the video recognition region to a region except for a region on which the superimposing information is superimposed.

6. A video recognition method of a video reception device configured to transmit and receive data through a communication network, the video recognition method comprising:

extracting a partial video for video recognition processing, from a video signal;

receiving content related information including feature information indicating a feature of the video signal;

setting a video recognition region to the partial video based on the feature information;

generating content recognition information in the video recognition region of the partial video;

transmitting the content recognition information to a video recognition device connected to the communication network so as to request the video recognition device to perform the video recognition processing, and obtaining a result of the video recognition processing from the video recognition device; and

obtaining additional information based on the result of the video recognition processing, from an additional information distribution device connected to the communication network.

7. The video recognition method according to claim 6, further comprising:

displaying, on a displaying unit, a video obtained by superimposing the additional information on the video signal.

8. The video recognition method according to claim 6, further comprising:

superimposing the additional information on the video recognition region of the video signal.

9. The video recognition method according to claim 6, further comprising:

outputting a signal for, requesting the content related information when the content related information is not input.

10. The video recognition method according to claim 6,

wherein, when the content related information includes the feature information related to a caption, the video recognition region is set to a region except for a region on which the caption is superimposed.

11. An additional information display system which comprises a video reception device, a video recognition device, and an additional information distribution device, the devices being configured to transmit and receive data to each other through a communication network,

wherein the video reception device includes:

an input unit configured to receive an input of a video signal, and content related information including feature information indicating a feature of the video signal;

a video extraction unit configured to extract a partial video for video recognition processing, from the video signal;

a video recognition region setting unit configured to set a video recognition region to the partial video based on the feature information;
