Streaming media host-host protocol is simply introduced below.Streaming Media refers to continue to send multimedia messages from one end
To the multimedia technology of the other end.It is not a kind of carrier of media that " stream " in Streaming Media, which is expressed in the technology, but a kind of
Persistently transmit the action of information.Stream media technology is transmitted, just in the form of streaming by being decomposed and being compressed multimedia file
Can it can be played out when a multimedia does not send over completely also by media player.Current network technology
The bandwidth that can reach is limited.If with original video by network transmission, being limited by the limitation of network bandwidth can make
Obtaining video playback becomes not smooth.The bandwidth space of video occupancy will be reduced in order to improve the experience of user, using H.264 regarding
Frequency coded format, the coded format can use the video quality good compared with low bit rate offer.H.264 coding provides high quality
Picture show and the interaction of low latency and frame updating, and reduce bandwidth occupancy.Contracted by the picture in server end
Put, the client of various screen sizes can be supported.Streaming Media mainly uses realtime transmission protocol RTP agreement and real-time Transmission
Control protocol RTCP carries out the transmission of data flow.RTP is used for providing the transmission end to end with feature of having a try, and it is not protected
The succession of data is demonstrate,proved, it is necessary to provide the guarantee of service quality by RTCP.
By the technical scheme, from anywhere in user can install camera in automobile, without by hardware device
Limitation, brings great convenience to user；User does not have to the display video information for switching different cameras, in terminal display screen
The screen information of multiple cameras is shown on multiple windows simultaneously, so that it may check the ambient conditions of motor vehicle environment, brought to user
Convenience, improves the experience of user；Achieve that easy to operate, cost is low without changing hardware device, realize letter
It is single.
Preferably, the display module, also applies the request instruction according to user, and the request instruction is included in terminal and shown
Show the subwindow number of screen display, display screen is accordingly divided into by the corresponding subwindow according to the subwindow number
Several subwindows, each subwindow are accordingly shown every road video information of the storage.
The specific embodiment of the present invention, the display module receive the request instruction of user, and the request instruction is used to set
The subwindow number shown on terminal display screen is put, after display module receives the request instruction, is wrapped according in request instruction
The subwindow number shown on ground terminal display screen is included, correspondingly, terminal display screen is divided into the subwindow to number, each
The subwindow is accordingly shown every road video information of the storage.According to the technical scheme, user can basis
The needs of itself, the subwindow number that terminal display screen is shown is arranged on, the video for showing which camera can also be set
Information, more preferable experience effect is brought to user.
As shown in Fig. 2 according to one embodiment of present invention, a kind of multi-window display method, methods described includes：
S201, obtain the multi-channel video information that multiple picture pick-up devices are sent, store it is described per road video information to corresponding
Under store path；
S202, according to the store path number of setting, terminal display screen is divided into the corresponding store path number
Subwindow, each subwindow are accordingly shown every road video information of the storage.
Preferably, step S201 is specifically included：
A URL address is distributed to each picture pick-up device；
According to URL addresses corresponding to each picture pick-up device, store path is set, and each store path corresponds to described
Each URL addresses；
The multi-channel video information that multiple picture pick-up devices are sent is obtained, stores every road video information to corresponding storage road
Under footpath.
Preferably, step S202 is specifically included：
According to the store path number, terminal display screen is accordingly divided into the son for corresponding to the store path number
Window；
Terminal display screen request idsplay order is obtained, and obtains URL addresses corresponding to each picture pick-up device；
According to the URL addresses of acquisition, based on Streaming transfer protocol, video corresponding to the URL addresses of storage is believed
Breath is transmitted on terminal display screen on corresponding subwindow, and is shown on the subwindow.
In specific implementation process, system distributes URL (URL) address, institute to each picture pick-up device
It is unique to state URL addresses.The system establishes data channel with the picture pick-up device, by being taken the photograph described in data channel reception
The video information sent as equipment.For example the data channel can be wireless tunnel, the video information of camera passes through
Wireless tunnel is transmitted to memory module.According to URL addresses corresponding to each picture pick-up device, store path is set, often
Individual store path corresponds to each URL addresses.After obtaining multiple cameras transmission multi-channel video informations, store described per road
Under video information to corresponding store path, that is, store to the store path of URL addresses corresponding to the camera.
In specific implementation process, according to the store path number of the memory module, accordingly terminal display screen is drawn
It is divided into multiple subwindows.Specifically, the store path number in memory module is obtained, correspondingly, terminal display screen is divided into
The subwindow of corresponding number.The specific embodiment of the present invention, by taking Android system as an example, in Android system, generally use
SurfaceView and MediaPlayer shows and played video.The page that terminal is shown is typically an Activity
Component, multiple SurfaceView components can be shown in an Activity, and a SurfaceView component corresponds to one
Subwindow, so it is achieved that the display of a screen multiple subwindows.Terminal display screen sends the instruction of request display, system
After receiving the order, URL addresses corresponding to each picture pick-up device are obtained, according to the URL addresses of acquisition, are assisted based on streaming media
View, by corresponding to the URL addresses of storage on video information transmission to terminal display screen on corresponding subwindow, and will described in
Video information is shown on the subwindow.Correspondingly, video information transmission corresponding to URL addresses storage each imaged
On to terminal display screen on corresponding subwindow, accordingly each shooting is shown in each subwindow of the display screen of the terminal
The screen information of head, so as in the video letter of the multiple cameras of display corresponding to the multiple subwindows of the display screen of terminal
Breath, user need not switch the video information that different cameras is shown, great convenience brought to user.
By the technical scheme, user does not have to the display video information for switching different cameras, in the more of terminal display screen
The screen information of multiple cameras is shown on individual window simultaneously, so that it may check the ambient conditions of motor vehicle environment, brought to user
It is convenient, improve the experience of user；Achieve that easy to operate, cost is low without changing hardware device, realize simple.
In summary, a kind of windows display system and method for the present invention, user do not have to the display for switching different cameras
Video information, show the screen information of multiple cameras simultaneously on multiple windows of terminal display screen, so that it may check automobile week
The ambient conditions enclosed, brought conveniently to user, improve the experience of user.
It should be noted that above-described embodiment can independent assortment as needed.Described above is only the preferred of the present invention
Embodiment, it is noted that for those skilled in the art, do not departing from the premise of the principle of the invention
Under, some improvements and modifications can also be made, these improvements and modifications also should be regarded as protection scope of the present invention.
