Embodiment
For the object, technical solutions and advantages of the present invention are more clearly understood, with reference to embodiment and accompanying drawing, to this
Invention is further described.
In the present invention, data acquisition is carried out to same monitoring scene from multi-angle, regarding for each angle is obtained by multiple passages
Frequency evidence, and be shown using picture-in-picture mode；Also in picture window interface display shortcut, with simplicity operation；And will note
Record file and carry out binding storage with video data, to improve the security of log file.It is that the present invention is supervised to video referring to Fig. 1
The method indicative flowchart recorded a video is controlled, it comprises the following steps：
Step 101, video recording instruction is received, the video recording instruction includes window display pattern, also comprising channel number and window
Corresponding relation between number；According to window display pattern display picture window, background painting face-port is included in the picture window of display
Mouth and picture-in-picture window, and in picture window interface display shortcut, the shortcut is imported comprising unlatching video recording key and file
Key.
For same monitoring scene, data acquisition, each network shooting are carried out from multi-angle using multiple web cameras
Machine is acquired to the video data of a certain angle of monitoring scene, encoded, and is then sent to NVR by the passage between NVR.
When needing, user sends video recording instruction to NVR, and the video recording instruction includes window display pattern, also comprising passage
Corresponding relation number between window number, one picture window of each passage correspondence, user can be configured to the corresponding relation；
Then, NVR includes background frame window and picture-in-picture according to window display pattern display picture window in the picture window of display
Window.Also show shortcut in picture window interface, the shortcut that user can as needed in direct operation screen window, nothing
Operation need to be simplified by the way of existing progressively click main menu, submenu to carrying out video recording control.It is this hair referring to Fig. 2
In display interface one when bright NVR is recorded a video, the example, data acquisition, three angles are carried out to monitoring scene from three angles
Degree is, for example, front, left side side and right side side；Shortcut includes 9 keys in figure, for 1-9 key in figure；When implementing,
Picture window interface can be clicked on and click on left mouse button, to eject shortcut menu, right mouse button is clicked on, then close quick dish
It is single.
Step 102, the open command that video recording key is opened on clicking on is received, same monitoring field is obtained from least two passages
Each angle video data of scape, are decoded to video data, are shown and decoded in respective picture window according to the corresponding relation
Obtained video flowing；The picture data that display screen is currently shown is stored.
After each picture window shows video data, the picture data that storage display screen is currently shown；Afterwards, as needed
The picture data of storage is extracted, displaying obtains the picture of picture-in-picture effect, just would know that the information of monitoring scene multi-angle.
When carrying out data storage, storage device can be then saved in again first by picture data storage to NVR hard disk
In；The storage device it is also possible that insertion is imprinted CDs etc., while display picture by picture data storage on imprinting CDs；
Further, in order to improve security, the NVR for supporting double imprintings can be inserted into two and imprint CDs, and one is main imprinting light
Disk, one be from imprinting CDs, it is main imprint CDs and it is standby imprint CDs in store the frame numbers that display screen is currently shown respectively
According to.
Step 103, the importing instruction that key is imported on clicking on file is received, log file is read from external equipment, it is described
Log file is the text recorded to video monitoring scene；The recording text of reading and the picture data that currently shows are entered
Row binding storage.
In order to further improve security, authority judgement can be all carried out after each shortcut is clicked on, sentenced when by authority
After disconnected, corresponding operation is just performed.For example：From at least two passages obtain same monitoring scene each angle video data it
Before, this method also includes：Verify, after checking, perform described same from the acquisition of at least two passages to opening authority
The step of each angle video data of monitoring scene.
For another example：Before reading log file from external equipment, this method also includes：Verify, pass through to importing authority
After checking, the step of performing the reading log file from external equipment.
