Along with the rapid development of the national radio and television broadcasting programs in recent years, the television programs had gradually formed for a variety of topics and styles, along with the program continues to introduce new forms, the new technical means of production of programs is also undergoing rapid changes. From the reporter shooting information back to station and then editing to final television production, and then transfer to pre-broadcast checking, until the reporter come to report directly from on the spot of the scene, the reporter sent the news back immediately, the timeliness of the program is growing stronger and stronger. Competition in the television media are also increasingly reflected in the speed of program reported, faced with unexpected news events, the reporter capability to quickly arrive at the scene is the key to the media competition success.This series of competition also requires constantly improving of program production techniques. Broadcast vehicle, as special television production equipment, is a collection of signal gathering, embedded effecting, subtitle overlaying, signal broadcasting and signal transferring and rebroadcast, working as a mobile television station, making recording and reporting of the program with a fast response and good flexibility characteristics. The involving content of the broadcast vehicle also covers professional equipments and techniques from shooting to all aspects of professional broadcast industry.On marks of the production strength of a TV station production, the broadcast vehicle and variety of loaded automotive professional equipment, the management and technical personnel of television stations must be seriously investigated the selection of equipment, and also take a careful analysis of the actual needs of the television in the purchase process of the broadcast vehicle. The main research target is to help professional and technical personnel to understand and master the technology of the broadcast vehicle and basic technical equipment and also general means of technical achieving, at the same time introduces the broadcast vehicle from equipment selection to the perspective of using on the broadcast vehicle’s various functions to achieve the principles and methods, meanwhile targeted for broadcast vehicle and equipment selection for rapid response and venues subject to limitations under the introduced, especially for the goal of rapid response reports show the existing technical means to be updated, compared to other broadcast vehicle functions, the design of the joint white balance adjustment, which is achieving secure broadcast signal system while target to the goal of rapid response reports. In addition the vehicle has a special design to guarantee the stability of the signal synchronization system, making the "nervous system" of the vehicle-even if the synchronization signal system in case of no backup of the same model equipment, can still provide a stable synchronization signal, which making the entire system’s stability greatly enhanced, and also makes the signal of the temporary external video equipment will not burden the system and still be used in the normal state.Compared to the same price of other types of vehicle, this designation of the vehicle system has a better stability and reliability and easy operation, while in the car also design with a more convenient way of servicing and fault detection methods, meanwhile the vehicle reached a high level in the recorded signal clarity, color saturation and other indicators...
