摘　　要：针对当前传统播出系统中文件化备播日益增多的需求,考虑到由于转码和传输过程中可能出现的MXF(Microsoft Foundation Classes)格式或数据错误,对MXF相关规范协议进行了研究。基于MFC(Microsoft Foundation Classes)设计了MXF文件数据信息自动检测报警系统,分析当前频道实时的在播节目单中所有素材的MXF文件参数信息,并比较与贵州广播电视台文件送播标准。该系统能自动检测出在播所有素材的MXF信息中存在的参数错误和完整性错误,有效的提高了安全播出能力,为减少了播出事故提供了一个有效的手段。MXF （Material Exchange Format） related specification protocols is researched, in response to the increasing demand for documented preparation in the current traditional broadcast system, due to possible errors in the MXF format or data during transeoding and transmission. And the MXF error information automatic detection alarm system based MFC （ Microsoft Foundation Classes） is designed, for analyzing the MXF file parameter information of all materials in the on -air program of the current chan- nel in real - time, and comparing it with the broadcast and broadcast standard of Guizhou Radio and Television Station. It can automatically detect the parameter errors and integrity errors in the MXF information of all broadcasted materials, effectively improve the safely broadcast ability, and provide an effective means for reducing the broadcast accidents.
