VIDEO RECEPTION DEVICE, ADDED-INFORMATION DISPLAY METHOD, AND ADDED-INFORMATION DISPLAY SYSTEM

摘要

Additional information related to video signals input from an outside is obtained and superimposed on the video signals. Hence, video reception device which is configured to transmit and receive data through communication network includes input unit, video extraction unit, control unit and additional information display control unit. The control unit performs control of requesting video recognition device to perform video recognition processing on a partial video extracted by the video extraction unit, and obtaining a result of the video recognition processing and display control information of additional information from the video recognition device. The additional information display control unit performs control of calculating a display ending time of the additional information based on a system time at which the video extraction unit extracts the partial video, and the display control information, and superimposing the additional information on the video signal based on the display ending time.

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; a video extraction unit configured to extract a partial video for video recognition processing, from the video signal; a control unit configured to perform control of transmitting the partial video 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 and display control information of additional information 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 perform control of calculating a display ending time or a display remaining time of the additional information based on a system time at which the video extraction unit extracts the partial video, and the display control information, and superimposing the additional information on the video signal based on the display ending time or the display remaining time.
