VIDEO RECEIVING DEVICE, VIDEO RECOGNITION METHOD, AND SUPPLEMENTARY INFORMATION DISPLAY SYSTEM

摘要

Video recognition processing regarding a video signal input from an outside is performed. Hence, video reception device (40) configured to perform transmission/reception of data through communication network (16) includes input unit (65), video extraction unit (45), storage unit (47), video recognition unit (66), and control unit (41). The video recognition unit performs at least one of online matching processing for generating second content recognition information from a partial video extracted by the video extraction unit, transmitting the second content recognition information to video recognition device (20) so as to request video recognition device (20) to perform video recognition processing; and local matching processing for collating the second content recognition information with first content recognition information stored in the storage unit.
