Detailed ways

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

Please refer to FIG. 1 , an embodiment of the present invention provides a device 100 for positioning and playing video applied in the field of video surveillance, including:

The receiving engine 101 is configured to generate a control signal according to a user instruction;

The user interface engine 102 is used to respond to the control signal from the receiving engine 101, and define a display interface, present a video playback progress bar on the display interface according to the control signal, and adjust the playback scale of the video playback progress bar to determine the display range of the video playback.

It can be seen that adjusting the playback scale of the video playback progress bar to determine the display range of the video playback can improve the flexibility in the detailed operation of the video progress. The product is generous and easy to understand, and the operation is simple, making it convenient for monitoring users to choose the video they want to play, and facilitate the user's interactive operation.

Please refer to FIG. 2 a , which discloses a display interface 200 defined by the user interface engine 102 . In the shown display interface 200, a video playback progress bar 201 is presented on the display interface according to the control signal, and the playback scale of the video playback progress bar 201 is adjusted to determine the display range of the video playback. The display range of the current playing video shown in the accompanying drawing is the range of the playing scale from 53 to 60; the boundary values 53, 60 are not shown in Fig. 2a, only 54, 55, 56, 57, 58, 59 are reserved. Here adjust the play video progress bar 201 play scale to determine that the display range of the play video can be expanded to from 53 to M, M is an integer greater than 60; it can also be reduced from 53 to N, and N is an integer less than 60. As shown in Figure 2b, the displayed range of the playing video can be narrowed down from 53 to 59.3. Especially in the field of high-speed monitoring, when playing a large number of images within 1 second, after adjusting the display range of the zoomed-in video, the 1-second time scale is enlarged, and then the scale accuracy within 1 second can be further detailed, and then the user interface engine 102 can obtain More detailed video indication accuracy in milliseconds, microseconds, etc. Meet the needs of video detail confirmation in the field of high-speed surveillance.

Referring to Fig. 3, optionally, the user interface engine 102 is also used to present the playback event progress bar 203 on the display interface according to the control signal; the playback event progress bar 203 matches the playback video progress bar 201 moment, and is used to identify the playback video The event information of the time period is determined, and the display range of the event information is determined by the display range of the playing video. Furthermore, after the monitoring video information is damaged or removed, the monitoring user can still obtain some key information from the event information, such as monitoring alarm information, or grading confirmation information for a certain time period, so that the user can easily understand the event information of the event to meet specific needs. For example, through the playback scale range of the playback event progress bar 203, and the identification range of the display frame 204, the event information is displayed on the display interface 200 by one or more of text, sound or image, etc. The device 100 can be applied in the monitoring field. The event information here can also include video reasons (alarm, timing, manual video), scene description, storage address, etc. According to the way of video triggering, video is divided into alarm video, timing video and manual video. According to different requirements of specific application scenarios, there are the following implementation schemes:

The event information for a certain time period includes: one or more of alarm information for a certain time period, video cause, scene description, or storage address.

Option 1: Alarm video, timing video and manual video exist at the same time, and three signs indicate which video modes the current video belongs to. For example, a stands for alarm video, a=0 means there is no alarm video at this moment, a=1 means there is alarm video; b stands for timing video, b=0 means there is no timing video at this moment, b=1 means there is timing video; c means manual video, c=0 indicates that there is no manual video at this moment, and c=1 indicates that there is manual video. These 3 logos are also saved in the video file, so that they can be obtained at any time when they are obtained.

Solution 2: Three video modes exist at the same time, they have priority, alarm video>scheduled video>manual video. If the current video is manual and the timing video condition is triggered, the video becomes a timing video; if an alarm occurs, the video file becomes an alarm video; if the current video is a timing video, an alarm occurs, the video file becomes an alarm video; During the video and alarm video, the video cannot be stopped manually. A mark is used to indicate the specific video mode of the current video. For example, z=0 indicates manual video, z=1 indicates timing video, and z=2 indicates alarm video. This value can be saved in the video file.

Optionally, as shown in FIG. 4 , the user interface engine 102 is also used to define an indicator cursor 205, and the video playback start point is determined by the indicator cursor 205 on the playback video progress bar 201. During playback, the indicator cursor 205 uses to indicate the current playing position, and optionally, the detailed position of the current playing here is 18:53. It can be understood that by adjusting the playback scale of the playback video progress bar 201 to determine the display range of the playback video, the accuracy of the playback time of the playback video is greatly improved, especially in the field of high-speed monitoring, when playing a large number of images within 1s, adjust the playback video. After displaying the range, the scale accuracy within 1s is detailed, so that the indicating cursor 205 can indicate in detail the video indicating accuracy in milliseconds, microseconds, and the like. Meet the needs of video detail confirmation in the field of high-speed surveillance.

Please refer to Fig. 5, optional, when adjusting the display range of the playing video progress bar 201 to determine the display range of the playing video, the indicator cursor 205 is fixed at the middle point of the playing video progress bar 201, and the display range of the playing video is to play the video The midpoint of the progress bar 201 is used as a reference to zoom in or out; during playback, the indicator cursor does not move, but the progress bar moves as a whole, thereby changing the overall display range of the playing video. For example, there is a continuous movement from 53 to 64 as from 54 to 65, from 55 to 66, ..., from 60 to 71 .... When the present embodiment is playing, when the playing video progress bar 201 moves to the end point of the video as a whole, obviously the scale displayed on the playing video progress bar 201 cannot continue to move. For example, from 60 to 71 is the end point of the video, and the final play instruction of the video is completed by moving the indicating cursor 205 from 60 to 71 midpoint.

Optionally, when adjusting the scale of the playing video progress bar 214 to determine the display range of the playing video, the indicator cursor 205 can also be fixed at a certain point in the playing video progress bar 201, and the display range of the playing video is determined by the progress of the playing video. A certain point on the bar 201 is used as a reference to zoom in or out; during playback, the indicator cursor does not move, but the progress bar moves as a whole, thereby changing the overall display range of the playing video.

Referring to Fig. 6, optionally, said adjusting the display range of the playing video progress bar 201 to determine the display range of the playing video may include: displaying from 53 to 60 based on the current playing video progress bar 201 scale, incrementing by adjusting the preset time period Or the decrement button 209, the display range of continuously expanding the playing video is from 53 to M, and M is an integer greater than 60; it can also be reduced from 53 to N, and N is an integer less than 60, and the preset time period here is from M to 52. It is also possible to move the display range of the playing video as a whole by dragging the arrow 207, such as changing the range of the current playback scale from 53 to 60 to from 54 to 61, or from 55.2 to 62.2, or from 61 to 68 to change the overall scale range. It is also possible to change the playback range from 52 to 61, or from 51 to 61, or from 40 to 73 based on the midpoint of the current playback scale from 53 to 60, and then perform proportional scaling or amplification. Of course, adjusting the scale of the video playback progress bar 201 to determine the display range of the video playback may also include: directly determining the display range of the video playback according to each preset time period in the slide button 210 . Before adjusting the scale of the playing video progress bar to determine the display range of the playing video, a date column 208 is also included, through which the date of playing the video is determined. In this embodiment, for example, through the play scale range of the play event progress bar 203 and the identification range of the display frame 204, the event information is displayed on the display interface 200 through a color image, such as through the color event bar on the play event progress bar 203 The color on 206 is to reflect specific event information, such as color event bar 206 red is warning, and color event bar 206 is yellow specific scene description etc.

Please refer to FIG. 7 , in the slide button 210, the display range of the playing video is directly determined according to each preset time period, specifically, by selecting the slide button 210, the preset time is directly determined after the slide button frame 211 is obtained on the display interface 200 segment, such as 15 minutes, 30 minutes, 1 hour, 24 hours, etc.
