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 (40) which is configured to transmit and receive data through communication network (16) includes input unit (65), video extraction unit (45), control unit (41) and additional information display control unit (46). The control unit performs control of requesting video recognition device (20) 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.
