Abstract

A device for positioning a playing video is provided. The device includes: a receiving engine, configured to generate a control signal according to a user instruction; and a user interface engine, configured to respond to the control signal from the receiving engine, define a display interface, present a video playing progress indicator on the display interface according to the control signal, and adjust a scale of the video playing progress indicator to determine a display range of the playing video. Meanwhile, a method and a system for positioning a playing video are provided. A video playing progress indicator is presented on a display interface according to a control signal, and a play scale of the progress indicator is adjusted to determine a display range of the playing video, so as to enhance flexibility in the detailed operation of a video progress.

Claims

1. A device for positioning a playing video, comprising:

a receiving engine configured to generate a control signal according to a user instruction; and

a user interface engine configured to respond to the control signal from the receiving engine, define a display interface, present a video playing progress indicator on the display interface according to the control signal, and adjust a scale of the video playing progress indicator to determine a display range of the playing video.

2. The device according to claim 1, wherein the user interface engine is further configured to present a play event progress indicator on the display interface according to the control signal, wherein the play event progress indicator is matched with the video playing progress indicator in time and is configured to identify event information of a determined time period of the playing video;

and determine a display range of the event information through the display range of the playing video.

3. The device according to claim 2, wherein the device is applied in a monitoring field, and wherein the event information of the determined time period comprises at least one of the following:

alarm information, a video reason, a site description, and a storage address of the determined time period.

4. The device according to claim 1,

wherein the user interface engine is further configured to define an indicative cursor, and determine a starting point for video playing through the indicative cursor on the video playing progress indicator, and

wherein the cursor is configured to represent a current play position in playing video.

5. The device according to claim 4,

wherein, when adjusting the scale of the video playing progress indicator to determine the display range of the playing video, the indicative cursor is fixed at a midpoint of the video playing progress indicator,

wherein the display range of the playing video is expanded or contracted based on the midpoint of the video playing progress indicator, and

wherein the cursor is not moved in playing while the progress indicator is wholly moved.

6. The device according to claim 1, wherein adjusting the scale of the video playing progress indicator to determine the display range of the playing video comprises at least one of the following:

continuously adjusting the display range of the playing video according to preset time periods,

directly determining the display range of the playing video according to a preset time period, and

wholly moving the display range of the playing video by dragging an arrow.

7. The device according to claim 1, wherein before adjusting the scale of the video playing progress indicator to determine the display range of the playing video, further comprises:

determining a date of the playing video when playing.

8. The device according to claim 1, wherein after adjusting the scale of the video playing progress indicator to determine the display range of the playing video, the user interface engine is further configured to:

find a video index file according to the scale of the video playing progress indicator,

determine a storage position of the playing video according to the video index file,

read the playing video file, and

output to display the read playing video file through the display interface after matching time length of the read playing video file with a precision of the video playing progress indicator.

9. A computer implemented method for positioning a playing video, comprising:

generating, by a control device, a control signal according to a user instruction;

responding, by a user interface engine, to the control signal,

defining, by the user interface engine, a display interface,

presenting, by the user interface engine, a video playing progress indicator on the display interface according to the control signal, and

adjusting, by the user interface engine, a scale of the video playing progress indicator to determine a display range of the playing video.

10. The method according to claim 9, further comprising:

presenting a play event progress indicator on the display interface according to the control signal, wherein the play event progress indicator is matched with the video playing progress indicator in time and is configured to identify event information of a determined time period of the playing video; and

determining a display range of the event information through the display range of the playing video.

11. The method according to claim 9, further comprising:

defining an indicative cursor, and

determining a starting point for video playing through the indicative cursor on the video playing progress indicator,

wherein in playing, the cursor is configured to represent a current play position.

12. The method according to claim 11,

wherein in the adjusting the scale of the video playing progress indicator to determine the display range of the playing video, the indicative cursor is fixed at a midpoint of the video playing progress indicator, and the display range of the playing video is expanded or contracted based on the midpoint of the video playing progress indicator;

and

wherein the cursor is not moved in playing while the progress indicator is wholly moved.

13. The method according to claim 9, wherein adjusting the scale of the video playing progress indicator to determine the display range of the playing video comprises at least one of the following:

continuously adjusting the display range of the playing video according to preset time periods, and

directly determining the display range of the playing video according to a preset time period.

14. A system for positioning a playing video, comprising:

a remote control configured to send a user instruction; and

a device for positioning a playing video, wherein the device is configured to generate a control signal according to the user instruction, respond to the control signal, define a display interface, present a video playing progress indicator on the display interface according to the control signal, and adjust a play scale of the progress indicator to determine a display range of the playing video.

15. The system according to claim 14,

wherein the device for positioning a playing video is further configured to present a play event progress indicator on the display interface according to the control signal,

wherein the play event progress indicator is matched with the video playing progress indicator in time and is configured to identify event information of a determined time period of the playing video;

and

wherein the display range of the playing video determines a display range of the event information.

16. The system according to claim 14, wherein the device for positioning a playing video is further configured to define an indicative cursor, and determine a starting point for video playing through the indicative cursor on the video playing progress indicator, and the cursor is configured to represent a current play position in playing video.

17. The system according to claim 14,
