Abstract
Embodiments of the invention provide a method and a device for realizing network high-definition camera shooting through a twisted-pair (namely a coaxial cable and a 220V electrical cable). The method and the device are characterized in that image data in a first set format is obtained by utilizing a sensor, and after the image data is processed and encoded, network transmission is carried out on a digital signal by utilizing the twisted-pair (namely a coaxial cable and a 220V electrical cable) through an HDPCC (High Definition Power Carrier Communication) protocol. The method and the device support an ONVIF (Open Network Video Interface Forum) protocol, the highest pixel of the real-time video stream reaches 5000000 pixels, and a camera shooting picture can be remotely browsed through a PC (Personnel Computer) and a mobile phone.
Description
Technical field
The present invention relates to a kind of network high resolution video and audio monitoring transmission, especially can collude twisted-pair feeder (i.e. coaxial cable and 220V electric power cable) transmission, it is possible in the upper cascade of a twisted-pair feeder (coaxial cable or 220V electric power cable).
Background technology
Current monitoring product is largely divided into simulation monitoring and network high-definition monitoring two kinds, simulation monitoring uses the transmission means of coaxial cable, and current market share is 70 percent, but it is low to have definition, cannot network, be not suitable for the application characteristic under low-light (level), the wide special environment such as dynamically.Network high-definition camera has the characteristic such as fine definition, favorable expandability, goes for most applied environment.But current network high-definition camera uses the transmission mode of Ethernet interface or optical fiber.So in the transformation process of simulated monitoring system upgrade of network high-definition monitoring system, wiring originally is the most all cancelled, and needs rewiring, causes the increasing of waste and quantities.
Summary of the invention
In order to solve the waste of existing monitoring system upgrading, the complexity of engineering wiring, the invention provides a kind of method and apparatus using twisted-pair feeder (i.e. coaxial cable and 220V electric power cable) to realize network high-definition camera.The method and device utilize imageing sensor to obtain the first setting format picture data, after image and data are processed, encode, network transmission is carried out by twisted-pair feeder (i.e. coaxial cable or 220V electric power cable) with digital signal, collection and the process of highest resolution 5,000,000 pixel can be realized, can also be cascaded by a twisted-pair feeder (i.e. coaxial cable or a 220V electric power cable) in network layout.Support ONVIF agreement, support that PC and mobile phone remote browse；Support NVR；Support IP addressing of address mode.So during the upgrading, engineering wiring of monitoring system, greatly reduce man power and material and time.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of image acquisition coded portion in (1) (2) in Fig. 2.
Fig. 2 is twisted-pair wire net transmission figure.(1) imageing sensor, utilizes sensor to obtain the first setting format picture data；(2) code conversion；Image and data are processed, are encoded into digital signal；(3) coaxial cable, by coaxial cable or 220V power line transmission；(4) coaxial cables, are cascaded by a coaxial cable or 220V electric power cable；(5) PC, mobile phone browse, and long-range PC browses, mobile phone browses.
Shown in Fig. 1: collect the first format picture data YUV4:2:2 by imageing sensor cmos, through being H.264 encoded into digital signal, IEEE802.1 agreement is converted into HDPCC agreement by homeplus detection and exports.
Shown in Fig. 2: (in figure 1,2) are the coding output of Fig. 1 image acquisition, (in figure 3) are transmitted by coaxial cable or 220V electric power cable, and can be cascaded by (in figure 4) coaxial cable or 220V electric power cable, (in figure 5) pass through network remote PC, mobile phone image browsing.
