Detailed description of the invention
Below in conjunction with the accompanying drawing of the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clearly
Chu, it is fully described by, it is clear that described embodiment is only a part of embodiment of the present invention, and not
It it is whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art are not making
The every other embodiment obtained under creative work premise, broadly falls into the scope of protection of the invention.
Embodiments provide a kind of video signal detection method, for being applied to large-screen splicing
The equipment of display system carries out batch and checks, detection process is simple, and efficiency is higher.The embodiment of the present invention is also
Accordingly provide the device that a kind of video signal detection method is corresponding.
Refer to Fig. 1, Fig. 1 and be applied to large-screen splicing display system for what some embodiments of the invention provided
The structural representation of video signal detection system.In FIG, video signal detection system includes pipe
Reason server, master controller, RGB processor, Video processor, decoder and detection equipment etc.,
Wherein, the said equipment can be high-performance personal computer (Personal Computer is called for short PC).
Manage server, master controller, RGB processor 1, RGB processor 2, Video process in FIG
Device 1, Video processor 2, decoder 1, decoder 2 and detection equipment are all connected on the network switch.
Wherein, RGB processor 1 through detection and can the reference video signal of outputting standard, RGB process
The signal of device 2 output is signal to be detected, and equally, what decoder 1 exported is the reference video letter of standard
Number, decoder 2 output is video signal to be detected.
Wherein, when testing, detection equipment issues order of windowing to master controller, master controller solution
Analysing order of windowing, transmitting order to lower levels is to RGB processor 1 and RGB processor 2 the most again, the most also can send out
Send serial port command to signal generator (not representing in Fig. 1).RGB processor 1 receives master controller
Order, gathers rgb signal, is encoded into network code stream by coded command, is sent by network code stream.
