Not All UHDTV is Created Equally • Spatial resolution not key factor for immersive TV viewing experience
– Not all 4K UHDTV solutions are “true” Ultra HD – For an immersive experience,
•At least 50-60 fps required for sports and other complex motion content •At least 10-bit depth data values required to avoid contouring quantization artifacts

UHDTV Needs to be Immersive • Will 4K UHDTV’s adoption be more like 3DTV or HDTV?”
– Depends on how we in the industry present it! – Can be transformative if the experience is immersive
• Implementation & standardization efforts continue – The high frame rate (HFR) debate continues
•100 fps, 120 fps, higher? •Fractional HFR (e.g., 120/1.001 fps) or integer only?
– High dynamic range (HDR), including peak white levels, fact finding and calls for proposed technologies just starting
– When will consumer displays implement 10-bit / 12-bit sample data values? – When will consumer displays implement expanded color space?
• Network infrastructure UHD-SDI? Real-time Video over IP?

Putting the Increased Pixels to Work
• Larger Screens – Occupy more of the Human Visual system
• Wider Angles of View
– More picture Content
– Greater Sensation of Reality
– Step closer to the “Stadium Experience”
