What’s now
• The move to IP - opportunity to discover what people watch in greater breadth and depth• gather consumers’ viewing behavior & video streams• combine them with enhanced EPG as input for a holistic live-stream data mining analysis
• generate a high-quality linked open dataset (LOD) describing live TV programming• market research on viewing behavior
