Based On The Study Of The Safety Systems Of The Cobranet Audio Transmission And Realization

Among the operational channels in the broadcasting station,the information flows are impeded due to the interconnection standards. In order to solve these problems,All-In-One is proposed. All-In-One is a technical frame work,under this frame work,the integration management system of broadcasting station consist of broadcasting the system,manufacture system,advertisement management system,news processing system,media property management system,remote transmission system,project management system,financial and the cost management system and so on,which will have the standard information exchanging protocols and the physical secure connection scheme. The ICM connection and the CobraNet transmission system are two characteristic composition modules in All-In-One.CobraNet is a network audio real-time transmission technology which synthesizes the hardware,the software and the communication protocols. One purpose of developing CobraNet is to find a real-time and specialized stable audio data transmission method on the high speed development computer network platform,this also will be one of important specialized audio domain development directions in the future. This had been paid attention in many years ago by the specialized audio equipment manufacturers all over the world,who proposed and developed many solutions one after another.With time passing,CobraNet has seized the market rapidly with its good intercmmunication, low cost construction,and reliability stable test. Our country's specialized technolog in audio field is at the developing phase,the situation of using CobraNet technology to build the large-scale acoustic transmission and the control system project is extremely rare.To solve the security of interconnection network,some merchants proposed the firewall and the anti-virus software scheme plan. Certainly,such scheme or similar ones are feasible to solve some major part security problem,but if higher request is needed by users,this can not satisfy the need of customer actually.Due to the technical principle, the firewall and the anti-virus software are effectual for preventing the majority attack and the viral dissemination,but not to the new method of attack and the virus actually.So we design the ICM secure transmission system.ICM is physical networks...
