Research And Improvement Of Performance Statistics Method For IPTV System

In terms of IPTV playback performance statistics,traditional IPTV performance statistics often fail to locate the current failure of the original data in the event of a failure because of its own lack of equipment and lack of good monitoring methods,Can not fundamentally solve the problem.In terms of network transmission,although there are some tools that can monitor the network status in real time,this method can only analyze the data at the network layer and can not resolve the problems existing in the IPTV set-top box itself.The network layer data and the set-top box itself are not effective Together,you can not quite clearly recognize the performance of the entire IPTV playback.Therefore,a complete set of IPTV performance statistics system is needed,which can perform statistics on the performance data of the terminal and upload it to the server in real time while the IPTV terminal set-top box is playing,thereby enabling the server to monitor the performance of the terminal in real time,Send a timely response to the situation.Based on the above background,in order to work in the IPTV Android smart set-top box,real-time statistics and calculation of its performance parameters of play,namely jitter,packet loss,delay value,program playback parameters.This paper studies and implements a performance statistics method based on IPTV broadcasting system.The main work of this paper is as follows:(1)Through the research of IPTV,TS transport stream,RTP protocol,performance statistics parameters and other aspects,The performance of other statistical methods,the method can store a large number of playback data through the Sqlite database can simultaneously calculate and monitor each parameter,and then take into account the Sqlite database and shell script,lightweight and low storage management costs can be effective Improve the efficiency of performance statistics;(2)studied the basic principles of statistical calculation of performance statistics,numerical analysis methods and code implementation,the calculation of packet loss rate and bit rate were studied in detail and improved,and for the calculation of the subject The results of the test in contrast,obtained the more satisfactory results.The calculated value is not much different from the actual values displayed by wireshark packet capture.(3)The performance statistics method of IPTV playback is researched and realized,and its playing stability and calculation accuracy are analyzed.Its working characteristics are tested.Has good working characteristics and can be used as a performance statistics method in the IPTV broadcasting system.
