So many of the most costly and complex faults in digital video delivery systems show up as intermittent, transient faults that take days, and sometimes weeks to locate, chew up key engineering resources for extended periods, and often require close vender cooperation to ultimately correct. Customer satisfaction during these sessions can plummet and make the provider more vulnerable to competitive pressures.
This 2008 CableTec EXPO paper by IneoQuest Senior Consulting Engineer Jim Welch, discusses and illustrates up-to-date and proven tools and techniques to rapidly debug common broadcast digital video, VoD, Video Insertion and HFC transient impairments. Case studies are used to illustrate their value. Emergining delivery systems offer new and exciting features that help scale current systems capabilities to meet new market demands, but are often more complex to troubleshoot when things go wrong. The techniques described in this paper include how to capture and describe the "bad thing" so that equipment and content providers can more quickly provide corrective actions to resolve the faults. Included are techniques and metrics that can help service providers determine system health and find impairments before subscribers start reporting them.
