DYNAMIC TROUBLESHOOTING OF SPECIFIC ETR-290 ALARMS IN A MPEG TRANSPORT STREAM

Abstract

The current scenario of Transport stream Monitoring and Analyzing is such that we are doing the analysis of the Transport Stream at the output end i.e. the Streams are analyzed at the receiver end and then the Troubleshooting is done by manually doing the required change and therefore is not dynamic. In this project the work has been done to analyze the output Transport stream just after the multiplexer output, and make changes to the transport stream after analyzing the stream for a specific ETR 290, Priority 1 alarm . All this is done without manual interception. For the real-time environment , the generated stream after Satellite Transmission are received back via a Ku,C band antenna and then are analyzed.. In this project the real time environment is simulated in the Multiplexing code itself .The Analyzer monitors the Multiplexed stream for a specific ETR-290 alarm and will make necessary changes in the repetition frequency of the that specific PID packet. The specific ETR-290 alarm we have taken here is PAT_error. The entire process takes place within the same Block wherein we don’t have to Increase or Decrease the Frequency of reception of a PAT packet by manually inserting the time frame. Here the Analyzer itself measure the PAT packet frequency and itself makes the adjustment whether to increase or decrease the frequency of that PAT packet by looping back to the multiplexer which generate PAT Packet..
