Specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is further described.
Referring to shown in Fig. 2, the present invention provides a kind of video playback method, includes the following steps:
S1, configuration display unit, play out to load video file；
S2, setting calendar cells to be associated with the recording date of the video file loaded in display unit, and make described aobvious
Show that unit jumps to the recording date and plays out；
S3, configuration dial plate unit, to control the progress of display unit playing video file and the selection of time precision.
Wherein, optionally, before step S1, further include a step S0: video file is deposited in storage unit.Step
Video file in rapid S1 in display unit load store unit plays out.
Wherein, the dial plate unit is to control the progress of display unit playing video file and the selection of time precision
Method is as follows:
Single finger slides dial plate and jumps video file by dial scale；
Two fingers kneading gesture can smoothly scale dial scale, change dial plate precision when zooming to default multiplying power.It is defaulted as
Mono- scale of 20min, variable precision have 10min, 5min, 1min etc..
The video file duration that the dial plate precision is loaded according to display unit is drawn in real time using Bezier
System, method are as follows:
(1), intermediate bar is drawn；
(2), angle between each scale is calculated according to current dial scale value, scaling multiplying power；
(3), scale is drawn to both sides respectively from intermediate；
(4), color filling region is drawn according to video recording sessions；
(5), it is repainted when play time, scaling multiplying power variation.
Referring to Fig. 3, the present invention also provides a kind of video playback systems, comprising:
Display unit is played out for loading video file；
Calendar cells to be associated with the recording date for the video file that display unit is loaded, and make the display unit
The recording date is jumped to play out；
Dial plate unit, to control the progress of display unit playing video file and the selection of time precision.
Wherein, optionally, which further includes a storage unit, for storing the video file.Display unit load
Video file in storage unit plays out.
Wherein, the dial plate unit is as follows to the method for controlling display unit playing video file rate:
Single finger slides dial plate and jumps video file by dial scale；
Two fingers kneading gesture can smoothly scale dial scale, change dial plate precision when zooming to default multiplying power.The table
Disk precision carries out real-time rendering using Bezier according to the video file duration that display unit is loaded, and method is as follows:
(1), intermediate bar is drawn；
(2), angle between each scale is calculated according to current dial scale value, scaling multiplying power；
(3), scale is drawn to both sides respectively from intermediate；
(4), color filling region is drawn according to video recording sessions；
(5), it is repainted when play time, scaling multiplying power variation.
Concrete principle of the invention is as follows:
(1) calendar cells are patterned into calendar:
1. calendar is optional 00 to divide 00 second any one day until today when 1970 01 month 01 day 00.
2. it can be by sliding come option date, but the date after today can not be chosen, the date after today is set to ash
It can not click.
3. having a colored point below the date for having video playback data under some date to prompt, indicating
There is video data on the same day.
Step is realized by calendar interaction:
1. obtaining the current date, the date locating for today is obtained.
2. obtaining number of weeks locating for No. 1 of the current moon, handle for convenience, defines 0,1,2,3,4,5,6 and respectively correspond
Sunday, Monday, Tuesday, Wednesday, Thursday, Friday, Saturday.
3. obtaining the number of days of current month.
4. the table using 7*7 shows monthly calendar, there is the day of data then to show, no data does not show for sky then.
5. when clicking the previous moon, when the button of the latter moon, then repeatedly 2,3,4 the step of repeat to obtain data and show
Show.
(2) dial plate cell picture turns to a dial plate:
1. single finger sliding dial plate jumps video playback time, can be across across the moon sliding in day.
2. two fingers kneading gesture can smoothly scale dial scale, change dial plate precision when zooming to certain multiplying power.Default
For 20 minutes scales, variable precision had 10 minutes, 5 minutes, 1 minute etc..
To sum up, it since this dynamic characteristic leads to that fixed figure of cutting cannot be used to carry out the displaying and rotation of dial plate, but adopts
Real-time rendering is carried out with Bezier.
Step is realized by dial plate interaction:
1. drawing intermediate bar.
2. calculating angle (radian) between each scale according to current dial scale value, scaling multiplying power etc..
3. drawing scale to both sides respectively from intermediate.
4. drawing color filling region according to video recording sessions.
5. being repainted when play time, scaling multiplying power variation.
(3) display unit turns materially player interface, also settable broadcast button, pause button, alarm button etc..
Using method of the invention, the loading procedure of the smart machine of similar Fig. 3 can be designed:
(1), when into playback interfaces, there is the time shaft operation guide of the dial plate of dial plate unit materialization in Fig. 3.
(2), default enters the playback on nearest date, and transverse direction calendar (calendar cells) selection can be used to mark orange dotted table
It is shown with the date of playback, does not indicate the yellow dotted expression same day without playback video, and can be selected by the month clicked on title bar
It selects and selects again in switching corresponding month, (tomorrow) sets grey not optional after today, and also there is playback video labeling in month when switching.
(3), sliding lower section dial plate (dial plate unit) time shaft can check the playback video at corresponding time point, dial plate sheet
Translucent as black, blue markings have been expressed as video, indicate yellow and are expressed as the alarm video that there are objects moving.It can be right
Corresponding video does screenshot video recording and mute or amplify.
The above description is only a preferred embodiment of the present invention, is not intended to limit the scope of the invention, all at this
Under the inventive concept of invention, using equivalent structure transformation made by description of the invention and accompanying drawing content, or directly/use indirectly
It is included in other related technical areas in scope of patent protection of the invention.
