In recent years, video monitoring system adopts digital camera and network transmission technology comprehensively, along with comprehensive covering of electrical network wide area wide-band-message communication network and data dispatching net, bandwidth promote and business development, for the application of monitoring remote video provides technical support.Teleconference system of State Grid Corporation of China nerve of a covering, province, and subordinate unit, and to the HDTV technical development, but do not extend to power plant and transformer station as yet; Each company building, scheduling building, high voltage substation, fire/water/nuclear power plant build up local security protection video monitoring system in succession, but because of the interface disunity, fail to satisfy the requirement of telemonitoring according to the security protection requirement; Along with the all-round popularization of unattended operation transformer station management mode, segment set control central station is built or is transformed Active Eyes, but does not consider the video transmission to superior unit; Each outlet of power marketing system is also building the marketing video monitoring system.
Above-mentioned each system is subordinated to different departments and specialty, with the disparity items construction, receives the restriction of different construction investments at different times, does not have unified planning.What video monitoring system adopted is the product and the software of many producers, different times, causes technology, interface and agreement incompatible, can't interconnect.H.261 the video coding technique aspect has especially, H.263, and technology such as MPEG-4.
Communication network constantly develops with the IPization direction towards broadband, and its main purpose is exactly professional for the multimedia Real-Time of carrying IPization, supports that especially fully high-quality video stream media is professional.The monitoring intelligentization of electrical network video monitoring system, network broadbandization, integrated platformization, the high Qinghua of video are the inexorable trends of future development.
The utility model content
The utility model purpose: the utility model technical problem to be solved is the deficiency to prior art, and a kind of electric power system video code conversion device is provided.
In order to solve the problems of the technologies described above; The utility model discloses a kind of electric power system video code conversion device; Comprise the video data input module; The video coding analyzer that is connected with the video data input module, the one group of Video Decoder that is connected with the video coding analyzer, H.264 encoder that is connected with Video Decoder and video data output module.
Among the present invention, said one group of Video Decoder comprises decoder H.261, any one or a few decoder in decoder, jpeg decoder, MPEG-1 decoder, MPEG-2 decoder and the MPEG-4 decoder H.263.Described video coding analyzer can correct analysis goes out to import the coded format of data and transfer of data to the decoder H.261 of coded format H.261; With the transfer of data of coded format H.263 to decoder H.263; With the transfer of data of coded format H.263 to decoder H.263; With the transfer of data of JPEG coded format to jpeg decoder; With the transfer of data of MPEG-1 coded format to the MPEG-1 decoder, with the transfer of data of MPEG-2 coded format to the MPEG-2 decoder, with the transfer of data of MPEG-4 coded format to the MPEG-4 decoder;
Described in the present invention H.264 encoder be H.264 form of standard with the yuv video digital coding, H.264 coded system satisfies under alap storage condition and to obtain good picture quality and low bandwidth image and transmit fast.
Among the present invention, said video data input module and video data output module have a network interface separately, are convenient to insert complicated network environment.
In the utility model, the video data decoding that described each decoder will be received separately becomes yuv data.
The utility model is changed the video code model of producer of different monitoring system through video code conversion equipment; Realize the unification of video coding part; Guarantee the consistency of each factory's station transmission of video images of electric power system, satisfy in electrical network video monitoring system and the interface specification requirement video coding.Every video code conversion equipment is supported the conversion of multichannel various video coded format, behind the employing video code conversion equipment, does not influence the normal operation of original video monitoring system.
Beneficial effect: the utlity model has following advantage: change the video code model of producer of multiple different monitoring system (1); (2) can realize that through this transcoding device original system satisfies electrical network video monitoring system and interface specification easily, has not practiced thrift cost and do not need to purchase in addition equipment; (3) this transcoding equipment is led the way by function, can realize complex environment is carried out the function of Route Selection; (4) do not influence the normal use of original system through installing this gateway device additional.
