Research And Implementation Of ITV User Quality Detection And Diagnosis Method

In recent years the rapid development of ITV services,the user increases,but the ability of operators to monitoring and diagnosis platform is not in place,the user perceived quality of the user side of the ITV can not guarantee the resulting ITV customer complaint rate has been high.This is a great obstacle to the development of ITV in the future,ITV as a new type of television media,mainly to provide high-definition 4K live on demand business,the quality of the network requirements are relatively high.Analysis of the user’s experience of perception can be very good for the development of ITV to provide a clear goal.Currently on the market are mostly passive monitoring on the server of ITV service,and end-to-end quality of service yet to achieve active monitoring.The content of this research is mainly aimed at the analysis and improve the user perceived quality on the side to watch the video of the user perceived quality influence index analysis and monitoring of video quality,and design a set in the user side can initiate a self diagnosis tool to achieve end to end service quality inspection test.In this paper,in order to improve the perceived quality of the user side of the ITV diagnosis as a research topic,detection and diagnosis of end to end at the user side program source,the development of ITV operation platform,diagnosis and remote diagnosis operation provides the user side to maintenance personnel,reduce customer complaints,ITV assistant APK integrated into the set-top box,to provide self service and remote diagnosis ability to the user.Main research contents:(1).Through to end quality monitoring model research and Analysis on the ITV side,construction and implementation scheme of diagnostic mode in the user side,describes the topological structure of the user to the user monitoring and diagnosis function,ITV initiated end-to-end quality monitoring at the user side through the existing nuclear capability,the user side of the ITV fault and predict in advance processing,improve the quality of the perception of the user’s side,thereby reducing the rate of complaints.(2).Through the study of STUN NAT through technology,realized in the active communication function of the set-top box and the server,to take the initiative to resource tree business layer initiated by Ping,traceroute connectivity and network diagnosis,timely find fault location,fault detecting problem from user autonomous detection ITV.Through the analysis of NAT network mode,and do processing,through the comparison of the advantages and disadvantages of STUN and STRN to determine the final way through.(3)In order to achieve the user independent monitoring and diagnosis,design and implementation of self diagnosis and fault reporting basic repair function on the set-top box Android ITV assistant into set-top box based on real-time monitoring of its own set-top boxes,to ensure the quality of the user side ITV perception.And to test and analyze these two functions.The innovations for this work can be summarized as follows:(1)ITV end to end quality monitoring and diagnosis,can be in the user side to achieve self diagnosis,and the diagnosis of the results reported to the server for analysis;(2)Designed a set of user side of the ITV diagnostic tool,friendly interface,easy to test.
