Pending Video segmentation is dynamic area and static region and identified by algorithm, and the video after mark then is sent into video wash with watercolours
Dyeing equipment；Video Rendering equipment receives the video of video server transmission and the area identification of video, is known according to area identification
Other dynamic area and static region, real-time rendering dynamic area and the content for updating dynamic area, and static region is only rendered
First frame simultaneously continues to use, and when static region changes, is rendered according to the region after change according to the foregoing mode that renders, until whole
Individual Video Rendering is completed so that Video Rendering equipment can be according to the algorithm of video server, the dynamic area to being partitioned into respectively
Domain and static region carry out different Rendering operations.
Refer to Fig. 2, there is provided a kind of flow chart of Video Rendering method, the present embodiment are applied to above-mentioned Fig. 1 in this way
In Video Rendering equipment come for example, in the Video Rendering equipment operation have Video Rendering program, pass through the Video Rendering
Program renders to the video to be rendered that video server is sent.This method comprises the following steps：
S202：The video and the area identification of video that the reception server is sent.
Wherein, area identification is that server is treated after render video analyzed, dynamic to can distinguishing for the video labeling
State region and the mark of static region.Such as this mark can be label or flag bit；Spy is preset such as in video data
Positioning is used as flag bit, and if dynamic area, then the flag is 0, and if static region, then the flag is 1；Or regarding
Frequency file is finally specified in digit and sets particular piece of data, and the particular piece of data is the dynamic area and quiet in video to be rendered
Pixel coordinate section corresponding to the difference of state region.
Specifically, after video to be rendered is divided into dynamic area and static region by server according to respective algorithms, according to
Video after mark is sent to Video Rendering equipment by the request of Video Rendering equipment.And the band generally taken up due to video file
It is wide larger, the operation such as the video to be rendered after mark can be encoded and be compressed before sending, to facilitate transmission, be serviced in addition
Static region in the video to be rendered that device is sent to Video Rendering equipment can only include in the duration of the static region
The first frame in static region, to reduce transmission quantity.
S204：Dynamic area and the static region in video are identified according to area identification.
Specifically, Video Rendering equipment receive server transmission mark after video to be rendered after, it is to be rendered to this
Video is rendered, and reads the area identification of video first before rendering, and the dynamic area of video is got according to area identification
And static region.Wherein, if video to be rendered has been encoded or compressed in server end, Video Rendering equipment is then first right
This document carries out the operations such as corresponding decoding and decompression；Further according to area identification, dynamic corresponding with area identification is identified
Region and static region.
S206：Playing sequence according to the frame of video in video renders each frame and current static area of current dynamic area
First frame in domain.
Specifically, Video Rendering equipment is identifying the dynamic area of the video to be rendered of server mark and static region
Afterwards, real-time rendering is carried out according to rendering requirements to all the elements of dynamic area, i.e., for dynamic area, according to broadcasting for frame of video
Put forward the image that sequence renders each frame；And for static region, in a period of time, the video content of static region is not substantially
Change, it is not necessary to real-time update, therefore when a certain region is identified as static region, only need to render this region and be identified
For the first two field picture in the time of static region, and all the time using the first frame after rendering within the duration of static region
Image is shown.
For example, a video file includes 20 frames.The first area of each of which frame is dynamic area, and second area is quiet
State region, when rendering, the dynamic area of 10 two field picture is rendered in sequence, and only render the static zones of the first frame
Domain, and in continuously display 20 frame the first frame second area, and the every of the first area after rendering is shown by video playback order
One frame, until 20 two field pictures render completion.
S208：When current dynamic area and current static region change, then broadcasting according to the frame of video in video
The first frame of the static region after sequence renders each frame of the dynamic area after changing and changed is put forward, until Video Rendering is complete
Into.
Specifically, if current dynamic area and current static region change, i.e., first frame in current static region is not
Corresponding region in next frame can be represented again, then the static state in next two field picture is obtained according to the area identification of next two field picture
Region, and the static region in the duration of the static region in next two field picture only in render image, and hold
The continuous dynamic area for rendering subsequent image frames.
For example, in the video file of above-mentioned 20 frame, the first area of each frame is dynamic area in preceding 10 frame, second area
For static region, and the first area of each frame is static region in the 11st to 20 frame, and second area is dynamic area；Rendering
When, first the second area of preceding 10 two field picture is rendered in sequence, and the first area of the 1st frame is only rendered, and in preceding 10 frame
All the time the first area of the 1st frame is shown, and the second area of each frame is shown by the playing sequence of 10 frame videos；Then in order
The first area in the 11st to 20 frame is rendered, and only renders the second area of the 11st frame, and in the 11st to 20 frame, is shown all the time
The first area of each frame for showing this 10 frame in order of the second area sum of 11st frame, until the display of 20 two field pictures is completed.
Above-mentioned Video Rendering method, all the elements that Video Rendering equipment is not required to treat render video are rendered, only
The first frame of the static region identified is rendered, and shows the first of static region all the time within the duration of this static region
Two field picture, the image of dynamic area need to be only updated, saves the computing resource for rendering each two field picture of static region, improved
The rendering efficiency of rendering apparatus so that current Video Rendering equipment can support the wash with watercolours to the video file of higher resolution
Dye requires, avoids the occurrence of when video resolution to be rendered is higher, the computing capability deficiency of rendering apparatus, and interim card occurs, fall
The problems such as frame, mosaic, improve the rendering effect to high-resolution video.
Fig. 3 is referred to, in a wherein embodiment, current dynamic area and current quiet in the step S208 in the above method
The step of state region changes can include：
S302：The duration for the static region that the reception server is sent.
Specifically, server to video when carrying out dynamic analysis, when certain region is identified as static state within a certain period of time
Region, and when the region is all identified as static region in follow-up continuous several frames, server then counts the static region
Duration, i.e., within the duration, the position of corresponding static region is fixed, and after reaching the duration, dynamic
Region and the position of static region change.Rendering apparatus also connects while the video to be rendered that the reception server is sent
Receive the duration of the corresponding static region of server mark.
S304：The duration corresponding with current static region is chosen from the duration of the static region received.
Specifically, Video Rendering equipment is chosen according to current static region from the duration of received static region
To the duration of static region.Such as Video Rendering equipment is carried out to video in render video according to video playback order
Rendered, the duration of the static region can also be ranked up according to video playback order, if Video Rendering equipment is opened
Beginning when rendering current static region, then directly reads the duration in current static region, if current static region it is lasting when
Between when reaching, then continue the static region in render picture frame, and read continuing for next static region in sequence
The duration of time, i.e. next frame picture frame.
S306：It is when the display time of first frame in current static region being equal to the selected duration, then current dynamic
State region and current static region change.
Specifically, when the display time of the first frame of a certain static region being equal to the duration of corresponding static region,
Then think that dynamic area and the static region of the next frame of video to be rendered are different from previous frame, it is necessary to according to the dynamic newly identified
Region and static region continue render video, i.e., identify the static region and dynamic area in next image frame according to area identification
Domain, and rendered in the manner described above.
Wherein, if having multiple dynamic areas and multiple static regions, it is necessary to count respectively simultaneously in a video file
The duration of each static region, after wherein the first static region reaches its duration, in next frame picture frame, the
One static region changes, and the display time of other static regions is not equal to the corresponding duration, then next two field picture
In frame, the display image of the first static region changes, and other static regions do not change and still show pair after rendering
Answer the first two field picture in the current duration of static region.Such as the first static region and the in a certain video file be present
During two static regions, duration of the first static region is 1 second, and the duration of the second static region is 2 seconds, when first quiet
When state region is changed into dynamic area after 1 second, when Video Rendering equipment can still keep the second static region display correspondence persistently
The first interior frame, without rendering the first frame of the second static region after 1 second again.
When rendering the video of complexity, single area identification can not accurately reflect the image change situation of video.Service
Device is needed to area identification corresponding to the video progress of complexity, and counts the duration of the static region after mark, and video
Rendering apparatus enables to each static region only reaching the duration corresponding to this static region by the above method
When, just need to render and show the content of next frame, by other static regions will not be changed is influenceed.Rendering regarding for complexity
During frequency, the rendering effect of video had both been ensure that, has also saved the computing resource of rendering apparatus to the full extent.
Above-described embodiment, Video Rendering equipment are judged static region and moved by the duration corresponding with static region
The situation of change in state region, by the method server can be made more accurately to identify the situation of change of video to be rendered, depending on
Frequency rendering apparatus can also realize more accurate rendering effect according to the recognition result of server.
Fig. 4 is referred to, Fig. 4 provides the flow chart of method for processing video frequency in an embodiment, and the present embodiment is applied in this way
Come to the server in above-mentioned Fig. 1 for example, on the server operation have video processing program, pass through the video processing program

To preset the weight of the rank M of complexity and processing requirement level n, such as respectively m and n, Processing Algorithm is then calculated
Grade=M × m+N × n, obtain corresponding algorithm further according to the grade of resulting algorithm.Wherein, Processing Algorithm can be
Frame differential method, deep learning algorithm or edge detection method etc..
S404：By pending Video segmentation it is dynamic area and static region by Processing Algorithm.
Specifically, dynamic analysis are carried out to pending video by above-mentioned Processing Algorithm, is by pending Video segmentation
Dynamic area and static region, so that client is to Rendering operations corresponding to the different zones progress of pending video：Real-time wash with watercolours
Dynamic area is contaminated, and the first frame is only rendered to static region and continues to use；When static region changes, according to the area after change
Domain renders according to the foregoing mode that renders, until whole Video Rendering is completed.
S406：Dynamic area and static region Adding Area are identified.
Wherein, area identification is that server is treated after render video analyzed, dynamic to can distinguishing for the video labeling
State region and the mark of static region.Such as this mark can be label or flag bit；Spy is preset such as in video data
Positioning is used as flag bit, and if dynamic area, then the flag is 0, and if static region, then the flag is 1；Or regarding
Frequency file is finally specified in digit and sets particular piece of data, and the particular piece of data is the dynamic area and quiet in video to be rendered
Pixel coordinate section corresponding to the difference of state region.
S408：When the video acquisition for receiving client is asked, then by the area of pending video and pending video
Domain identifier is sent to client.
Wherein, video acquisition request is the acquisition video to be rendered that client (i.e. Video Rendering equipment) is sent to server
Request, video to be rendered is the video after server process, including pending video and area identification.
Specifically, the bandwidth generally taken up due to video file is larger, can be before sending to the video to be rendered after mark
Encoded and the operation such as compress, to facilitate transmission, in the video to be rendered that server is sent to Video Rendering equipment in addition
Static region can only include the static region in the first frame in the duration of the static region, to reduce transmission quantity.Visitor
After pending video and the area identification of pending video that family end the reception server is sent, according to above-mentioned Video Rendering method
This video is rendered.
In above-mentioned method for processing video frequency, pending Video segmentation is by server by pending video according to respective algorithms
