Description
Technical field
The present invention relates to the technical field of video monitoring, specifically a kind of embedded main mouth automatic detection of video recording equipment and
The method of switching.
Background technology
The embedded video recording equipment generally used in monitoring includes embedded digital video recorder (DVR), embedded NVR and embedded mixed type
DVR。
Wherein embedded digital video recorder (DVR), i.e. DVR, be one kind can connect the analog acquisitions such as analog video camera, ball machine its
The embedded type network video that vision signal carries out local output echo and Video coding is locally stored, network real-time video is propagated
Equipment.
Embedded NVR, i.e. Network Personal Video Recorder, it is that one kind can connect and control network IPC (web camera) front end, will
The video data that IPC is transmitted is locally stored and forwarded, and decodes and show IPC on the output interface of NVR equipment
The equipment of the real time video signals gathered.
Embedded mixed type DVR is the embedded digital video recorder (DVR) built-in hard disk video tape recorder equipment all with NVR functions.
It is many such embedded with the continuous improvement of embedded digital video recorder (DVR), NVR, mixed type DVR special chip disposal abilities
Equipment possesses and provides the video output of two or more, according to the difference of video frequency output content, these video outputs
It is named as " main mouth " and " auxiliary mouth " respectively, user interface synchronization is only displayed in wherein some or one group of video frequency output
On mouth, there are mouth based on the video output of user interface output, mouth supplemented by other.On main mouth, user can be by menu to embedding
Enter operation and the parameter setting that formula video recording equipment is localized.
Existing embedded video recording equipment can not all accomplish to video output whether based on mouth automatic decision, Zhi Nengyi
The instruction provided according to user switches over.On the embedded digital video recorder (DVR), NVR, mixed type DVR equipment for possessing main mouth and auxiliary mouth, use
When family only has the display to be connected with embedded device, often because the position or the setting of main mouth of not knowing main mouth are changed
Become, it is easy to display has been connected on auxiliary mouth and can't see user interface can not operate embedded equipment, cause user confuse or
User is forced to patch video line again, this is very not convenient or even infeasible under some application scenarios；In addition, user will show
Show device from main mouth extract be connected to after auxiliary mouth, it is necessary to set manually main eloquence can carry out it is some operation it is also inconvenient.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of embedded main mouth automatic detection of video recording equipment and the side of switching
Method.
The present invention is adopted the technical scheme that to solve technical problem present in known technology:
The main mouth automatic detection of embedded video recording equipment of the present invention and the method for switching, including procedure below：
A, the level state of pin 6 in 9 pins of VGA video outputs, when pin 6 is high level, then VGA are detected
Video output is blank state, and when pin 6 is low level, VGA video outputs are the state being connected with display；
B, the state of insert-pull detection pin in HDMI video delivery outlet is detected, judges that HDMI video delivery outlet connects display
State；
C, embedded video recording equipment obtains the main mouth when last time preserved in configuration file is run automatically on startup
Arrange parameter；
D, if above-mentioned steps A has display to connect with a video output is only detected in B, automatically that this video is defeated
Outlet switches to main mouth, mouth supplemented by the setting of other video outputs；If it is not detected by any video frequency output in above-mentioned steps A and B
Mouth has display connection, then pre-configured video output is arranged to by information when being run according to last time in user profile
Main mouth, mouth supplemented by other video outputs；If detect that at least two video outputs have display company in above-mentioned steps A and B
Connect, then the configuration file preferentially run according to last time sets main mouth；If the video output of the display of access is not in first wife
The row of file are put, then setting first detects mouth based on the video output for being connected with display, and other video outputs are all
Supplemented by mouth；
E, detection is currently located at the connection status of the display of main mouth, if the display of current main mouth is no longer on connecting shape
During state, then above-mentioned steps D is reruned, and new main mouth is switched to according to operation result.
The present invention can also use following technical measures：
Described has multiple video input mouths and is connected respectively with different video delivery outlet on embedded video recording equipment
Display device as multiple displays.
USB interface is set on described embedded video recording equipment, and keyboard and mouse are connected by USB data line.
Described each video output exports different or identical video information or user operation menu simultaneously.
The present invention has the advantages and positive effects of:
The main mouth automatic detection of embedded video recording equipment of the present invention and the method for switching, being capable of the embedded video recording of automatic detection
The connection status of each video output of equipment and display, and judge mouth or auxiliary mouth based on a certain video output, and then from
It is dynamic to carry out main mouth switching.When there was only an interface display in succession in multiple video outputs of embedded video recording equipment, from
The dynamic video output that will be connected with display device set based on mouth and here it is shown that on device output user interface method, for
Family operation provides facility.
