The assembly of bright embodiment can be arranged with various different configurations and design.Therefore, the most right
The detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit claimed
The scope of the present invention, but be merely representative of the selected embodiment of the present invention.Based on the present invention
Embodiment, the institute that those skilled in the art are obtained on the premise of not making creative work
There are other embodiments, broadly fall into the scope of protection of the invention.
Along with innovation and the increase of transmission bandwidth of wireless communication technology, wireless real-time monitoring technology
Increasingly coming into one's own, its range of application is more and more wider.The movement currently mainly used is real-time
Monitor mode mainly has two kinds: a kind of is that the audio frequency and video using special-purpose terminal to move formula are adopted
Collection, this kind of special mobile audio-video collection terminal directly uses mode and the backstage prison of wireless telecommunications
Ore-controlling Role (network platform) is attached, and directly utilize establish connect and will collect
Video data uploads to monitoring system；Another kind is by mean of the photographic head of mobile phone and carries out sound
Video acquisition (in such cases, mobile phone is equivalent to Mobile audio/video collecting terminal), mobile phone
The wireless network and the background monitoring system that are directly covered by base station are attached, and upload and regard
Frequency evidence.
Two ways described above is respectively arranged with pluses and minuses, first kind of way, uses special-purpose terminal to enter
The mode of row video data acquiring is the most professional, and terminal is easily installed and uses, and records effect
Fruit preferably, in the application that a lot of mobilitys and professional requirement are the strongest, possesses certain excellent
Gesture；But, specialty terminal mostly is war products, or is used by restricted stronger manufacturer,
General user cannot see, and the most more cannot use, and, specialty terminal cannot be for backstage
Monitoring system need to carry out function extension and extension, also cannot fit in conjunction with mobile Internet
The improvement required for other industry.The second way, uses mobile phone to carry out video data acquiring
Mode, owing to the adaptation ability of mobile phone is relatively strong, can open up by the way of writing APP
Exhibition mobile phone is for the tenability of the business of different industries, by open towards mainstream operation system
Interface, is also easier to realize and different system, the docking of device, operates also relatively side simultaneously
Just, a lot of people get used to the mode of operation of mobile phone A PP；But, move using mobile phone
During dynamic audio-video collection, do not support external camera due to mobile phone, during video acquisition
Terminal must be held towards target subject by hands, operate not convenient, in the field carrying out instant picture photographing
Under scape, easily cause the dislike of the person of being taken.Meanwhile, in order to accomplish video data real-time on
Passing, mobile phone must complete three work in the same time, be video data acquiring, coding respectively
With upload.Owing to the internal memory (be primarily referred to as caching) of mobile phone is less, if complete simultaneously this three
Individual work, then can cause mobile phone EMS memory to be taken greatly, easily causes the collapse of mobile phone.
For above two mode problem encountered, this application provides and instant picture is carried out
The method of network real-time live broadcast, as it is shown in figure 1, the method comprises the steps:
S101, external camera sends immediately shooting the video data obtained to mobile phone terminal；
S102, the video data that external camera is sent out by mobile phone terminal is forwarded to the network platform.
Before step S101, external camera is generally hand-held by user, or passes through The Cloud Terrace
It is fixed on certain building/ground Deng fixed structure, it is also possible to be to use holder to be fixed on
On the clothes of user.Afterwards, can by the manually opened external camera of user, and pass through external
Video pictures outside photographic head recording, and collected sound signal simultaneously.External camera is passed through
It has been mature technology that shooting obtains the process of video data, only many explanations at this.The application
In the method provided, external camera can be that the simple external camera of function (refers to solely
Stand on mobile phone, can directly carry out the photographic head of video record and forwarding), such as small volume
Minisize pick-up head.This external camera can keep with mobile phone terminal in the way of using wireless connections
Connect (as being connected with mobile phone terminal by WIFI signal)；Can also is that employing signal transmssion line
Connection status (as being connected by flexibly connecting cable) is kept with mobile phone terminal with mobile phone terminal.External
Photographic head can pre-build with the connection of mobile phone terminal, and remains connection status；
Can also be will be front temporarily to mobile phone terminal transmission data (performing step S101) at mobile phone terminal
Set up, now, in external camera after mobile phone terminal transmission ED, just can break
Open the connection (referring mainly to disconnection of wireless connect) of mobile phone terminal and external camera.
In step S101, external camera needs to send, to mobile phone terminal, the video counts that shooting obtains
According to.The video data that shooting can be obtained by external camera in advance before sending is carried out simply
Process, with ensure external camera to mobile phone terminal transmit the most smooth.In order to be different from specialty
Picture pick-up device, when the external camera used in method provided herein is minisize pick-up head
When, external camera is set and only possesses video record and video is transmitted to the merit of mobile phone
Can, and do not possess other functions, it is arranged such, then can reduce external shooting to a certain extent
The volume of head, it is simple to user uses.Now, external camera possesses two basic modules, point
It is not acquisition module, is used for gathering external image, and acoustic information, and generates video data；
Sending module, sends the video data generated to mobile phone terminal.Generally external camera and mobile phone
End, at a distance of relatively near, be difficult to situation about divulging a secret during data are transmitted, therefore, be not required to
Encrypting module is set inside external camera；It is similar to, short-distance transmission, transmission speed
Also very fast, accordingly it is also possible to save complex coding module inside external camera,
Thus reduce the volume that external camera is overall.But, it is contemplated that the internal memory of mobile phone should not be by mistake
Take, it is therefore preferable that arrange coding module in external camera, for by regarding of generating more
Frequency is according to carrying out coding and code stream conversion.
In step S102, the video data that external camera is provided by mobile phone terminal is uploaded to net
Network platform.
Method provided herein, in entirety from the point of view of, it is only necessary to user arranges one at mobile phone terminal
Individual application program (APP), and the mobile phone that this APP can be different shared, also
It is exactly that user need not mobile phone is carried out unnecessary adjustment, it is only necessary to tackle and configure one in mobile phone terminal
Individual external camera, it is possible to complete the purpose uploading in the network platform by video data.Right
For domestic consumer, using method provided herein to greatly reduce user to spend
The cost taken, for Professional Photography equipment, user has only to additionally increase by one
Individual minisize pick-up head, Costco Wholesale, operation easier etc. aspect is more suitable for general domestic consumer.
Meanwhile, mobile phone can support again the APP application enriched, and the APP application on mobile phone is all right
Just realized by simple coding updating, iteration, so and then using the new APP can be right
The video flowing forwarded carries out respective handling.Further, method provided herein is more suitable for moving
Dynamic video monitoring, broadcast live, the fields such as evidence obtaining of enforcing the law.During use, user can be by long
External camera is connected on the clothes of user (avoiding hand-held) by short folder, it is also possible to use cloud
External camera is fixed on the ground by platform, on automobile.
Step S102, mobile phone terminal, after the video data received, needs to the network platform
(such as network side equipment such as video reception servers) transmits these video datas.Mobile phone is one
Function is more comprehensive, can transform the smart machine that space is bigger, and the popularity rate of mobile phone is higher,
The scope of application making this method is bigger.Mobile phone terminal video data is uploaded to the network platform it
Before (before step S102), need video data is carried out code stream conversion, on the one hand, use
Fixed code stream format transformation carries out code stream conversion and can be easy to the network platform and be read out, identify,
The transmission of data can also be easy to；On the other hand code stream conversion can also make the big of video data
Little it is more suitable for current network strength, i.e. ensures that the video data after code stream conversion can more flow
Smooth is uploaded to the network platform, ensures resolution simultaneously.It should be noted that external camera
Before mobile phone terminal transmitting video data, video data is encoded, external shooting
While head encodes, the video data after coding can be carried out code stream adjustment (networking shape
The when that condition being good, convert video data to high code check code stream；The when that networking situation being bad,
Converting video data to low bit-rate code stream, resolution drops to VGA), and further by code stream
Video data after adjustment sends mobile phone to.
The property transformed of mobile phone terminal relatively strong (referring to mobile phone A PP energy iteratively faster), when mobile phone terminates
After receiving video data, user passes through operating handset, it is possible to achieve carry out more kinds of to video
The operation of class.Specifically, user can carry out local preview to the video data received,
Video data is sheared and assembled, video data is stored in this locality etc..Wherein, examine
Consider to the internal storage space of mobile phone terminal limited, it is difficult to the video data that memory capacity is excessive.Cause
This, mobile phone terminal, video data is stored in this locality when, has two kinds of storage modes, and these are two years old
The premise of the mode of kind is that mobile phone terminal first to detect local residual memory space.Concrete, the first
Mode, is when local residual memory space is more than predetermined threshold value, then the video counts that will receive
It is stored in this locality according to original resolution according to (video data that external camera is sent), as
The video data that mobile phone terminal receives is 720P, then mobile phone terminal stores locally stored space
Video data be also 720P.The second way is, when local residual memory space is less than pre-
If during threshold value, then the resolution of the video data received is reduced, and by after resolution reduction
Video data be stored in this locality, so, then alleviate the burden in locally stored space.Need
Illustrating, this threshold value can be divided into multiple rank by mobile phone terminal, and namely mobile phone terminal is along with this
The reduction of ground residual memory space, reduces the resolution of video data further.Certainly, also may be used
To be when locally stored space is too low when, mobile phone terminal directly will be stored in the video counts of this locality
According to middle pickup key frame image data, and the view data not being key frame image data is deleted
Remove, to discharge certain memory space.Can also is that hands when locally stored space is too low when
Machine end alert, to point out user to change storage card.To ensure that mobile phone terminal can be normal
Work.
Except mobile phone can be saved in this locality, external camera while being uploaded by video data
While video data is sent to mobile phone terminal, it is also possible to video data is saved in external taking the photograph
As in head.As photographic head uses battery to be powered, and the working method of dual code stream is used to enter
The transmission of row video data and preservation, main bit stream, auxiliary code stream are respectively used to real-time transmission of video number
According to mobile phone terminal, and video data is saved in the SD card of external camera.
Preferably, in order to ensure that mobile phone terminal can be normally to network platform uploaded videos data, can
Determine and use the code stream conversion side of which kind of specification transmitting quality according to current mobile network
Formula carrys out uploaded videos data.Concrete, method provided herein also comprises the steps:
Mobile phone terminal obtains the network transmission quality between current phone end and the network platform；
Described network transmission quality is sent by mobile phone terminal to described mobile phone external photographic head；
Photographic head adjusts the code stream of described video data according to the network transmission quality that mobile phone returns
To certain preset value, and the video data after described adjustment code stream is sent to mobile phone；
The video data that described external camera sends out is uploaded to network and puts down by described mobile phone terminal
Platform includes:
Video data after mobile phone terminal will adjust code stream is uploaded to the network platform.
Concrete, after network transmission quality is sent to external camera by mobile phone terminal, external take the photograph
As head adjusts the code stream of described video data to certain according to the network transmission quality that mobile phone returns
Preset value.Specifically, external camera has prestored multiple code stream conversion regime, has made
With different code stream conversion regimes, same video data carried out the video obtained by code stream conversion
The definition (resolution) of data is had any different.As the first code stream conversion regime can be by duration
It is the video data A code stream of the 5 minutes video data that is converted into 50M, this kind of situation, code
The definition of the video data circulated after changing is higher；The second code stream conversion regime can be by duration
It is the video data A code stream of the 5 minutes video data that is converted into 40M, this kind of situation, code
The definition of the video data circulated after changing is medium；The third code stream conversion regime can be by duration
It is the video data A code stream of the 5 minutes video data that is converted into 30M, this kind of situation, code
The definition of the video data circulated after changing is relatively low.
When wireless network transmissions quality is good when, fine definition (resolution) can be used
Code stream conversion regime (data volume of the video data obtained after code stream conversion is bigger) is to video counts
According to carrying out code stream conversion, to ensure the definition of video；When wireless network transmissions is second-rate
Time, can use the code stream conversion regime of low definition that video data is carried out code stream conversion,
To ensure that video data can upload on network in real time.Similar, uploading voice data
When, it would however also be possible to employ voice data is compressed by similar mode, concrete compression side
Formula is such as provided at pre-determined intervals and samples voice data, and interlude is the longest, then compress
Ratio is the highest, and the degree of distortion is the biggest.
In order to be further ensured that video data can effectively be uploaded to the network platform by mobile phone terminal,
Can also is that in method provided herein, when mobile phone terminal detects that current mobile network transmits
The when that quality being very bad, no longer use the mode sending video flowing that video data is uploaded to net
Network platform, but extract key frame image data from video data, and will be drawn into
Key frame image data encodes, and further the key frame data after coding is uploaded to net
Network platform.
For the ease of using, can before use, by user or manufacturer in advance external
Arranging Quick Response Code on photographic head, mobile phone just can be directly obtained this by scanning this Quick Response Code
The numbering of external camera, and then set up wireless connections by this numbering and external camera.With
