Abstract

Recentadvances inresidentialbroadband accesstechnologies have ledtoawaveof commercialIPTVdeployments. AsIPTVservices are rolled out at scale, it is essential for IPTV systems to maintain ultra-high reliability and performance. A major issue that disrupts IPTV service is the crash of the set-top box (STB) software. The STBdirectlyresides inside the consumer’s home network andprovides the essential interface to both the user and the network to deliver rich content that goes well beyond traditional TV. To understand the potential causes of STB crashes, we perform an indepthstatisticalanalysisfocusedontherelationshipsbetweenSTB crashes,videostreamcontent,anduseractivities. Ourinitialresults suggestthat(i)impairedvideostreamsmaycauseSTBcrashes,and (ii) continuous STB usage may gradually degrade the STB health over time. Categories andSubject Descriptor
