The method and the device of the invention can test based on the actual playing effect of the set-top box terminal, can obtain the actual watching experience of the user on the set-top box terminal equipment, realize the video service quality test during the video playing of the set-top box and the EPG browsing by the mode of image recognition and packet capturing analysis, and can compare the data of the program source side and the set-top box user side, thereby realizing the consistency comparison function of the IPTV/OTT video service. The device has the characteristics of integration and portability, can improve the deployment efficiency of the test environment of equipment, and has the advantages of low device deployment cost, low video test cost, simple test configuration, wide test content, consistent test environment and user environment and closer test result to the actual perception of a user compared with the prior art.

The embodiments of the present invention have been described in detail with reference to the drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the gist of the present invention.
