The network video system that some embedded devices are arranged generally all is the independently request watched of the needs of the passive reception client of box, then video code flow is sent to the client place, decodes at the client place and plays.Because all requests of watching all send to embedded device, embedded device must be able to be handled multichannel and watch request, and in general, single embedded processing equipment only can be handled tens of roads client and watch request.After exceeding the treatable maximum user's numbers of single embedded processing institute, the request that more user's request is watched can't be handled.

And utilizing the P2P technology to come file in download ripe relatively, BT, eMule etc. becomes the download software that people use always.Along with the fast development of Streaming Media and network technology, by the internet transmission multimedia particularly live video stream more and more receive publicity.But owing to need take the very big network bandwidth by the internet transmission multimedia, traditional C/S framework adopts the server forwards pattern, and bandwidth that server is limited and disposal ability have been difficult to support large-scale consumer to use.The P2P technology has solved this difficult problem effectively, each user is when Streaming Media is watched in download, upload one's own resource to other users, effectively utilized each user's bandwidth and disposal ability, will the bandwidth and the disposal ability of server be required to be distributed to effectively on each node.

The utility model content

The technical problems to be solved in the utility model is: provide a kind of with traditional video monitoring equipment and the Internet connection transmission of video that gets up, the network video system that can watch for a large number of users.

The purpose of this utility model is to provide a kind of integrated P2P technology, the network video system that traditional video monitoring equipment and Internet connection are got up at above-mentioned technical problem.It is that a cover can be opened the video monitoring video data, it is transferred on the Internet embedded video processing unit of being watched by a large number of users.

The utility model is to solve the problems of the technologies described above the technical scheme that is adopted to be: a kind of P2P of utilization technology realizes that traditional monitor video inserts the device of the Internet, described device comprises at least one P2P management server, an embedded video collection compression device (P2P video processor) that is connected by network with the P2P management server, and the P2P driver module that on this equipment, moves, and some browsing terminal machines, this device makes realizes sharing of video monitoring video data between each browsing terminal machine, alleviate the pressure that embedded video is gathered compression device (P2P video processor) greatly.

The embedded video collection compression device (P2P video processor) that relates in the utility model comprises embedded SoC chip or the DSP based on ARM, and this equipment mainly moves operating systems such as linux, VxWorks.This equipment possesses the Video signal processing module, and network process module comprises the equipment of external memory and internal memory.This equipment can be finished the video acquisition briquetting, and the data after the compression are put into the real time data buffering area of certain width, sends it to browsing terminal machine on the Internet by embedded P2P module.

The control information that the P2P management server mainly is responsible between browsing terminal machine and P2P video processor is mutual, assists to set up between each terminal P2P and connects.

The browsing terminal machine comprises that PC, mobile phone etc. have Presentation Function, links to each other with the Internet, equipment that can the browse network video.

The beneficial effects of the utility model are: the P2P video processor can couple together traditional video surveillance system and Internet, realizes collection, coding, the transfer function of video.With video monitoring image by the P2P Network Transmission to the Internet, under the situation that does not change traditional monitor video system, video monitoring image can be transferred on the Internet network, browse for a large amount of browsing terminal machines.Universal day by day along with network application, this kind device is having a wide range of applications aspect the monitor video in real time in open tradition.

Embodiment

Traditional supervisory control system is by video camera, DVR, and monitor constitutes.In this manner, supervisory control system is the system of a sealing, can't open by a large number of users on the Internet.In order to reach the purpose that real-time video is opened to interconnected user on the network, can adopt the mode that in system, adds the P2P video processor.Mode shown in Figure 1, traditional video monitoring equipment inserts the Internet schematic diagram by the P2P video processor.Do not change original video monitoring system, only connect the video connecting line, it is linked to each other with the P2P video processor, link to each other with the Internet by the P2P video processor in vision signal output place of every road of DVR.Under this access way, P2P video processor equipment to the vision signal of original supervisory control system without any interference.After P2P video processor equipment is handled vision signal, pass the signal to browsing terminal machine on the Internet by network.The browsing terminal machine is PC, perhaps mobile phone, and processor by the browsing terminal machine and display unit are decoded and are shown.Wherein, P2P video processor equipment has been used embedded and multimedia communication technology, is a kind of network terminal that can separate connection Internet.This equipment adopts the full-embedded type designing technique, need not rely on miscellaneous equipment and just can independently be connected into the TCP/IP network, realizes the collection of video, the coding transmission function.

Above-mentioned P2P video processor hardware comprises video signal processing module, network process module, power module, master chip processor (SoC or DSP), external memory storage (Flash/SD Card/Hard Disk) and internal memory (as DDR2 SDRAM etc.).As Fig. 2, P2P video processor hardware module schematic diagram.Power module mainly is responsible for the power supply of each module of P2P video processor hardware, ensures each hardware module steady operation.Video signal processing module mainly is responsible for amplifying the vision signal of linking from video interface, after being translated into digital signal, compress by compression unit that (can be used as independent asic chip exists, also can be used as the part of master chip processor and exist), send into master chip processor (SoC or DSP) then, if what insert is digital signal, then can directly sends into the master chip processor and handle.In the master chip processor, the data after overcompression is handled send to data on the network by network process module by the P2P module.
