VIDEO RECEPTION DEVICE, VIDEO RECOGNITION METHOD AND ADDITIONAL INFORMATION DISPLAY SYSTEM

摘要

Video recognition processing regarding a video signal input from an outside is performed. Hence, video reception device configured to perform transmission/reception of data through communication network includes input unit, video extraction unit, storage unit, video recognition unit, and control unit. 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 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 stored in the storage unit.

1. A video reception device configured to be capable of performing transmission/reception of data through a communication network, the video reception device comprising:
an input unit configured to receive a video signal; a video extraction unit configured to extract a partial video for video recognition processing from the video signal; a storage unit configured to store first content recognition information acquired from a video recognition device connected to the communication network; a video recognition unit configured to perform at least one of: online matching processing for generating second content recognition information from the partial video, transmitting the second content recognition information to the video recognition device so as to request the video recognition device to perform video recognition processing; and local matching processing for collating the second content recognition information with the first content recognition information stored in the storage unit; and a control unit configured to perform control of acquiring additional information from an additional information distribution device connected to the communication network, the additional information being based on a result of the online matching processing or a result of the local matching processing.
