Specific embodiment
Patent of the present invention is described in further details below with reference to the drawings and specific embodiments：
Embodiment 1：
As shown in Figure 1-2, a kind of portable audio video network live broadcast system, including sending ending equipment and connect
Receiving end equipment；
Sending ending equipment include microprocessor, power module, video camera, microphone, flash storage, insert
Pull out formula memory and network interface；Video camera, power module, microphone, flash storage, plug-in storage
Device and network interface are connected with microprocessor；Network interface is communicated to connect by Ethernet with receiving device.
Sending ending equipment also includes the FPGA module for the control that resets being connected with microprocessor.
Described microprocessor is Hi3512 processors.
Described microphone is wireless microphone.
Described video camera is digital camera.
Described receiving device includes portable computer and projecting apparatus.
The main body of sending ending equipment is case type structure, and microprocessor and flash storage are arranged at main frame
In case, the backboard of mainframe box is provided with power interface, reset switch, network interface, earphone interface, microphone and connects
Mouth, power supply indicator, toggle switch, status indicator lamp and SD card groove.
System is not only integrated with video camera, and the built-in WEB server on software view；Can access
Earphone and microphone wirelessly or non-wirelessly, support voice bidirectional intercommunication.
A built-in flush type WEB server in the (SuSE) Linux OS that patent of the present invention is used.This
The head end video collecting device ccd image sensor of patent of invention passes through the real-time pictures image for collecting
Data Format Transform is sent to Hi3512, and Hi3512 carries out image coding and decoding to these huge data flows, and
Deliver to flush type WEB server.Ethernet is delivered to through network interface.If input video source is not CCD, and
When being analog video, Hi3512 is connected to as video AD converter using TVP5150.Flash storage
Effect be storage bootstrap and application program, all of reset source of system all first passes around FPGA module
Reseting logic is selected, and finally exports reset signal by FPGA module, and the various pieces to system are answered
Position.
Original video is acquired by imageing sensor, then turns original video data by Hi3512
Change digital of digital video data into.Because original video data is very huge, and is not suitable for directly transmission, because
This, H.264 they must be compressed by high performance video compression standard.Video counts after encoded
According to that can be transmitted by Internet network environment, the requirement of real-time video output transmission is fully met.
Devise the function of WEB server simultaneously due to Hi3512 control panels, therefore client can be straight
Browser was connected to carry out real time access.And management server be mainly used to it is continual carry out real time access,
The video data that will be received simultaneously is stored in the middle of SD card, is called after being provided with.
Rigging up and debugging process
1. equipment crossover network cables are directly connected to PC.
2. the IP address of PC is set to and the same network segment of equipment.For example：Equipment IP ground when dispatching from the factory
Location is 192.168.1.19, and the IP of PC just could be arranged to 192.168.1.10, and subnet mask is
255.255.255.0。
3. DC12V power supplys are connected, and now power supply indicator is bright.
4. the connection lamp (orange) of network interface can be lighted network connection in 5 seconds under normal circumstances, number
Can be flashed according to indicator lamp (green), now the physical connection of equipment is completed.
5. whether test equipment starts normally.Under WINDOWS according to<Start→run→cmd>
Operation, opens command Window, is input into Ping192.168.1.19, if there is data to return, shows to start normally；
6. when with IE browser access equipment first, it is necessary to which temporary decrease security setting is so as to by ActiveX
Component is disposably installed in network, from browse select tools → internet option on menu-→ safety-
→ self-defined rank-→ ActiveX control and plug-in unit>, set level of security for it is low or in, and click replacement.
7. IE browser is opened, and the IP address of input equipment is such as in IE browser address field：
http：// 192.168.1.19, is logged in keeper's identity, carries out parameter setting, is reached sound, image and is most preferably passed
Send mode.
8. PC is connected on router with netting twine, related setting is carried out to router.Outer net logs in visit
Asking needs to carry out port mapping to terminal network router where equipment.
