Design And Implementation Of Background Monitoring System For Television Broadcasting

Television broadcasting is gradually getting rid of the disk and the tape combiningbroadcasting, and realize the pure digital broadcasting with Radio and Televisionindustry developing rapidly.Traditional monitoring methods are mainly composed ofhardware and the software is complementary.It cost most and the operation is complex,there is also no way to monitor centrally.It already can’t be satisfy of the change whichis brought by the digital broadcasting.This topic analysed some of the key questions in the background monitoringsystem of television programmes broadcasting in depth, and designed a set ofbackground monitoring system which can satisfy of the requirement of TV station.ThisSystem is mainly composed of two subsystems,they are Medium resource managementnetwork monitoring subsystem and Broadcast network monitoring subsystem,and it’s atotal of eight big modules: system configuration module, database and web sitemonitoring module, software process monitoring module, storage devices monitoringmodule, file monitoring module, alarm log recording module, alarm module,multichannel video monitoring module. System configuration module and filemonitoring module mainly use the webservice technology, and adopt the model of C/Swhich is three layer architecture; Database and web site monitoring module use theSDK which comes which C#to access web or database to determine if it is anomaliesby it’s returning information; Software process monitoring module uses WMItechnology to monitor the process information of the remote computer; Storage devicesmonitoring module includes secondary storage devices monitoring and K2video serverdevices monitoring, this module use WMI technology to monitor secondary storagedevices, get K2video server devices’information by sending AMP commond；Alarm logrecording module mainly use the.net Framework2.0WriteLine method of StreamWriterclass with utf-16encoding to write the log information; Alarm module uses "kernel32"beep interface functions to realize; multichannel video monitoring module usesdirectshow technology, with the aid of its own Filters and the third party developedFilters to realize broadcasting TS Files and controling. The subject has realized functions of system setup information accessing;Monitoring Exception of server; monitoring the client’s process cpu usage,memory-intensive; monitoring storage device capacity; monitoring program files andMD5checksum; multichannel video monitoring, logging and alarm eventually.Thissystem has began running at variours television stations at present and gotten the usershigh praise.
