Getting Stronger Every Day

4K LCD TV shipments grew nearly 400% Y/Y to reach 4.7 million units worldwide in Q1’15. Volume barely dropped from Q4’14, with especially strong demand in China during the Chinese New Year holiday season. The slowdown in overall WW TV growth has not seriously affected the 4K TV segment, which continues to benefit from falling price premiums, expanded selection, and growing content availability. Overall, 9% of all TV shipments in Q1’15 were 4K TVs, but more than 31% of 50" and larger TVs were 4K TVs. (IHS 6/8/2015)

Hard To Make Them Any Larger?

• Sharp’s 120‐inch LCD display is the world’s largest from a single cut

• It’s 4K Ultra HD, of course!• No plans to sell it as a TV yet –

only as  a commercial display• Vizio has also shown this TV• Rolled on Sharp’s Gen 10 fab in

The Many Flavors Of UHD

Page 14: THE 4K EVOLUTION - scte.org · – 4K streaming in place at Netflix, Amazon Prime – First UHDTV Blu‐ray player is shown (Panasonic) – UHDTVs reaching price parity with same‐size

• UHD displays can come in many different sizes. Examples:

– 3840x2160 pixels = Ultra HD (CEA), or 4x 1080p (1.77:1 aspect ratio)

– 4096x2160 pixels = 4K (Sony), closer to cinema formats (1.89:1 aspect ratio)

– 3840x2550 pixels = Panasonic 4K Toughbook tablet (1.5:1 aspect ratio)

– 5120x2160 pixels = Widescreen 4K LCD TVs (2.37:1 aspect ratio)

– 5120x2880 pixels – Widescreen HP/Dell 5K computer monitors (1.77:1 aspect ratio)

Quad HD has 4x the resolution of 2K (1920x1080) displays (8,294,400 pixels)

With blanking interval, typical 4K frame measures 4400 pixels x 2250 pixels

Aspect ratio is the same - 1.77:1

Page 16: THE 4K EVOLUTION - scte.org · – 4K streaming in place at Netflix, Amazon Prime – First UHDTV Blu‐ray player is shown (Panasonic) – UHDTVs reaching price parity with same‐size

The viewing distance decreases for Quad HD – about half that for 2K

No benefit to Quad HD in small displays, except for large workstation monitors on desktops (close viewing)

4K image captured with high dynamic range

HDR provides higher contrast and better shadow detail, but requires 10-bit and 12-bit color rendering

Page 21: THE 4K EVOLUTION - scte.org · – 4K streaming in place at Netflix, Amazon Prime – First UHDTV Blu‐ray player is shown (Panasonic) – UHDTVs reaching price parity with same‐size

• The challenge is to reproduce images with at least 15 stops of light from black to white!

• HDR will substantially increase pixel clock rates and data payloads for UHD 

• Consumers readily see and understand HDR as an enhancement

• 10‐bit display panels are now shipping for use in televisions and monitors

• A new color space has been defined for UHD displays

• ITU BT.2020 has a much larger area within green/yellow

• High color saturation and luminous intensity must be combined (HDR)

• Total number of color shades for 10‐bit color is 1,048,576

• 8‐bit color will be inadequate for displaying UHD content!

• Why is support for fast clock rates so important?– High dynamic range increases grayscale values and color shades– Wide color gamut, plus increased color rendering = Deep Color (10‐bit and up)– Faster frame rates are becoming popular for 4K production (60 Hz and up)

• More content is being served from PC‐like devices– These products output an RGB (4:4:4) signal exclusively– Gaming and PCs will usually run 10‐bit or 12‐bit color– Fast refresh rates are essential to these applications

• MPEG‐4 was first standardized in 2001• H.264 (Advanced Video Coding) announced in 2003• AVC can cut the bit rate in half for equivalent image quality over MPEG‐2• Capable of intra‐frame compression (MPEG‐2 is not)

– Greater efficiency for an equivalent GOP size (50% target)– Variable block sizes, multiple motion vectors now possible– Sub‐pixel compression to ¼ for luma, 1/8 for chroma

If so, that requires 10-bit color.What codec is in use? (H.264, H.265) H.265 is 50% more efficient than H.264.How large a screen is being used for viewing?
