att_abstract={{Recent advances in residential broadband access
technology have led to a wave of commercial IPTV deployment.
As IPTV services 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, which directly
resides inside the consumer’s home network and provides
the essential interface to both the user and the network to
deliver rich contents that go well beyond traditional TV. To
understand the potential causes of STB crashes, we perform
in-depth statistical analysis on the relationship among STB
crashes, video stream contents, and user activities using logs
collected from a large commercial IPTV system. Our initial
results suggest that (i) impaired video streams may cause
STB to crash, and (ii) continuous usage of STB may gradually
degrade the STB health over time.}},
