Abstract
The invention belongs to safety-security area, there is provided a kind of low code stream high definition network head, including acquisition module, data processing module, data encoding and transport module, wherein：Data encoding uses LY Z matrix coders, and transport module is to be based on H.264 encoding.Compared to the conventional high-definition camera for being directly based upon and H.264 encoding output, the characteristics of low code stream high definition network head that the present invention is provided has fine definition, less code stream and bandwidth, so as to also correspondingly reduce the memory space of hard disk in storage, the cost of video monitoring is greatly reduced.
Description
Technical field
The invention belongs to safety-security area, it is related to a kind of IP Camera, is taken the photograph more particularly to a kind of low code stream high-definition network
As head.
Background technology
Video monitoring is the important component of safety and protection system, and with the development of smart city, video monitoring turns into
An important step in the construction of smart city.Traditional monitoring system includes that front-end camera, transmission cable, video monitoring are put down
Platform.Video camera can be divided into network digital camera and analog video camera, can be used as the collection of head end video picture signal, and it is one
Plant the stronger integrated system of prevention ability.Video monitoring is enriched and is widely used in its directly perceived, accurate, timely and information content
Many occasions.The video monitoring product having in the market has analog video to monitor and Network Video Surveillance.Traditional simulation
Video Supervision Technique develops highly developed, stable performance, more to simulate camera collection analog video signal, then passes through
Coaxial cable is transferred to Surveillance center, because signal is inevitably declined in transmitting procedure by various interference and signal
Subtract, transmission over long distances has certain difficulty, the problem of transmission over long distances is solved using analog optical fiber transmission, but greatly increase
The cost of system；Further, since analog signal transmission is generally carried out using base band mode so that video camera and monitor terminal
Structure can only use man-to-man form so that the topological structure of whole system becomes complicated, increased the cost of comprehensive wiring,
If desired video camera is controlled, also needs additional control circuit.With developing rapidly for computer networking technology, internet is
Through extremely popularizing, the networking of video monitoring system forward direction, digitlization and intelligentized direction are developed.Wherein, IP Camera, letter
Claim IPC, combined by network code module and analog video camera.The simulation that network code module collects analog video camera
Vision signal compression coding into data signal, such that it is able to be directly accessed network exchange and routing device, so IP Camera
The various video datas for photographing, Surveillance center can be immediately delivered to by network.In recent years, the popularization with network and net
Network technology is continued to develop, and this IP Camera has been widely used in multiple fields, such as security protection, education, business, medical treatment,
Government utility etc..Existing IP Camera can realize high definition rank, and resolution ratio is 1920 × 1080P, and code stream is 8M, and some are taken the photograph
As head is by changing compression algorithm, video data is compressed and code stream can be compressed to 4M as used H.264 to encode, even if
So, thus the arrangement camera of large area triggers high bandwidth and massive store demand are existing so that monitoring cost is high
High definition network head far from meeting current demand, therefore in the urgent need to a kind of low code stream high definition network head with
Reduce the cost of video monitoring.
The content of the invention
The purpose of the present invention is in view of the shortcomings of the prior art, there is provided a kind of without high bandwidth and the low code of massive store
Stream high definition network head.
To achieve the above object, the technical solution adopted by the present invention is as follows：
A kind of low code stream high definition network head, including video acquisition module, data processing module, data encoding and transmission
Module.Wherein, the data encoding uses LY-Z matrix coders；H.264, the transport module is based on encoding.The data
Coding module carries out LY-Z matrix coders to initial data, it is considered to which compatible various video storaging equipments, the technical program increased
Based on the transport module for H.264 encoding, i.e., finally led into H.264 coded format using reconvert after the conversion of LY-Z matrix coders
Network interface transfers are crossed in depositing defeated or display device.
In a kind of above-mentioned low code stream high definition network head, the video acquisition module is by camera lens and photo-sensitive cell group
Into.
In a kind of above-mentioned low code stream high definition network head, the photo-sensitive cell is CCD or cmos component.It is described photosensitive
Element completes IMAQ and analog-to-digital conversion.
In a kind of above-mentioned low code stream high definition network head, scenery projects image by the optical imagery that camera lens is generated
On sensor surface, electric signal is then turned to, by being changed into data image signal after analog-to-digital conversion (A/D) conversion.
In a kind of above-mentioned low code stream high definition network head, the data processing module is made up of DSP and memory cell.
The data processing module completes treatment and the primary encoder of data, and by the data storage after treatment in storage chip.
The low code stream high definition network head that the present invention is provided is to increase tool on the basis of conventional high definition network head
There is the coding module of LY-Z matrix coders and the dual code stream output function for H.264 encoding, and conventional high-definition digital camera compares,
Video code flow can be reduced to 500K by 8M on the premise of definition is not changed after LY-Z matrix coders, i.e., than traditional base
Low by more than 90% in the camera for H.264 encoding, even with H.264 coding output, its output code flow is also based on than conventional
H.264 the camera for encoding is low by more than 87%, and this causes that transmission cost and carrying cost are all substantially reduced, and is the big of smart city
Area popularization lays the foundation.
Brief description of the drawings
Fig. 1 is a kind of low code stream high definition network header structure connection block diagram of the embodiment of the present invention.
Specific embodiment
In order that present disclosure is easier to be clearly understood, below in conjunction with specific embodiment to present disclosure
It is described in detail, described embodiment purpose is merely to illustrate and describes the current optimal mode of the present invention, but this
The protection domain of invention is limited by embodiment described herein never in any form.
Such as Fig. 1, a kind of structured flowchart of low code stream high definition network head of the invention, including acquisition module, number are shown
According to processing module, data encoding and the part of transport module three, data encoding uses LY-Z matrix coders, and transport module is to be based on
H.264 encode.Video acquisition module is made up of camera lens and photo-sensitive cell, and photo-sensitive cell completes image from CCD or cmos component
Collection and analog-to-digital conversion.Scenery is projected in image sensor surface by the optical imagery that camera lens is generated, and then turns to telecommunications
Number, by being changed into data image signal after A/D conversions.Data processing module is made up of DSP and memory cell, mainly completes data
Treatment and coding.Data coding module carries out LY-Z matrix coder conversion to initial data, for compatible other videos storage
Equipment increased based on the output module for H.264 encoding, i.e., using reconvert after LY-Z matrix coders into H.264 coded format,
It is transferred to finally by network interface or USB interface in depositing defeated or display device.Increase LY-Z matrix coder modules so that shooting
The output code flow of head is greatly lowered than regular camera, video transmission bandwidth is correspondingly greatly lowered and video storage is empty
Between, reduce the cost of video monitoring.
