An embodiment of the invention discloses a video signal detection method. The video signal detection method is used for carrying out batch inspection on equipment applied to a large screen splicing display system, and is simple in detection process and high in efficiency. The video signal detection method comprises the steps of: triggering a first-path signal processor to obtain a source signal and encoding the source signal to obtain a benchmark reference network code stream, and triggering at least one path of second-path signal processors to obtain the source signal and encoding the source signal to obtain a to-be-detected network code stream; acquiring the benchmark reference network code stream from the first-path signal processor, and acquiring the to-be-detected network code stream from the at least one path of second-path signal processors; and converting the benchmark reference network code stream into a target video signal, converting the to-be-detected network code stream into a target to-be-detect
