This invention relates to the field of video signal processing and fault diagnosis technology. Addressing the problem that existing video capture chips easily misjudge "no signal" when signal attenuation occurs, making it difficult for users to distinguish between cable quality issues and physical disconnections, this invention discloses an automatic detection method.
