Video content detection can guarantee the quality of digital television. Video content automatic detection system is used to replace the manual detection. Their algorithms have low detection efficiency and high CPU occupancy rate. Aiming at this problem, we propose a new efficient video content detection algorithm in this paper. The detection efficiency of the algorithm is much higher than that of traditional algorithms, and the detection accuracy is higher. The algorithm proposed in this paper can be used for the detection of black fields, white fields, green frames, blue frames, single color frames, color loss frames, etc.
