1. A video reception device for performing transmission/reception of data through a communication network, the video reception device comprising:

  • a reception circuit configured to receive a video signal;

    a video extraction circuit configured to extract a partial video for video recognition processing from the video signal;

    a memory configured to store a local database transmitted from a video recognition device connected to the video reception device via the communication network;

    a video recognition circuit configured to generate second content recognition information from the partial video, transmit the second content recognition information to the video recognition device to request the video recognition device to perform online matching processing so as to collate the second content recognition information with first content recognition information and to acquire a result of the online matching processing, and perform local matching processing for collating the second content recognition information with the local database stored in the memory and to acquire a result of the local matching processing; and

    the video recognition circuit is further configured to generate next viewing information based on a viewing history stored in the memory, anda control circuit is configured to;

    perform control of transmitting the next viewing information to the video recognition device,acquire, from the video recognition device, the local database generated based on the next viewing information,transmit the result of the online matching processing or the result of the local matching processing to an additional information distribution device connected to the communication network, andperform control of acquiring additional information from the additional information distribution device connected to the communication network, the additional information being based on the result of the online matching processing or the result of the local matching processing, andthe video recognition circuit is configured to estimate a time zone and a channel, in which viewing is implemented next, and generate the next viewing information based on the viewing history stored in the memory.
