Abstract

Video recognition processing regarding a video signal input from an outside is performed. Hence, video reception device configured to transmit/receive data through communication network includes video recognition unit. The video recognition unit is configured to perform at least one of: online matching processing for generating second content recognition information from a partial video extracted by video extraction unit, transmitting the second content recognition information to video recognition device so as to request video recognition device to perform video recognition processing; and local matching processing for collating the second content recognition information with first content recognition information included in a local database stored in storage unit.

Claims
