| With the background of tri-networks integration,the interactive TV of the cable TV network is rising.All kinds of integration services have been promoted.An integrated management platform covering radio and television,interactive TV,TV Internet,video value-added services and other services,appeared.Although the current business platform has some methods of monitoring,but their data can not be effectively integrated and the monitoring model can not be effectively united.The center can not monitor the distributed points completely.Therefore,a complete review of the existing business platform for radio and television is needed.Besides,a deep analysis of business form and content is also required.It is supposed to be a united monitoring and management platform which has our own feature.It can be in line with tri-networks integration and can also meet the needs of business monitoring.This thesis,starting from the background of tri-networks integration,first emphasizes the significance of the study of the subject.The present research findings of video and network monitoring field at home and abroad are also discussed.What's more,based on the overall structure of the existing business,it states an overall plan and design of the monitoring and management platform,hardware deployment,indicators and security aspects from the whole design ideas.By the means of Agent,SNMP,HTTP and other monitoring ways,the monitoring and management platform for data collection methods were designed and implemented.Finally,the video signal acquisition mode of the center and the distributed points was designed and implemented.The STB video signal of the center is collected by using the video compression card.The STB video signal of the distributed points is collected by using the infrared remote control equipment.The structure of the infrared remote control device and the external circuit were designed.At the same time,the way designed to display the data comes from the center and the distributed points. |
