Mining the IPTV Channel Change Event Stream to Discover Insight and Detect Ads

Figure 5

Graph with ad-prediction on an ad segment during a news show where our prediction model predicts the segment too soon. The interval in the chart represents 5 minutes (with each bar representing 10 seconds) on July 22, 2015, from 19:33 to 19:39. In the case of a regular commercial break, the anticipation and channel switching before the segment starts triggers a false detection.
