Making 4k better than HD

Differentiating 4k from HD 4k has to be differentiated A consumer sitting further from the from HD in three ways: screen than the HD viewing distance cannot discern more detail in 4k than • Higher resolution in HD • Wider color gamut Diagonal HD Viewing 4k Viewing Inches Distance Feet Distance Feet • Display more colors 85 • 10.4 5.2 Higher dynamic range 65 8.0 4.0 • Better shadows and highlights

vxYCC color for 4k and HD

xvYCC Color • Background: – xvYCC is a color space that supports a gamut larger than the color space of HDTV which is called Rec 709 – xvYCC was proposed by Sony and published in January 2006 as an IEC standard – xvYCC makes use of code values that are not defined in Rec 709 – The Bravia XBR8 supported xvYCC but the feature was apparently removed later models • Blu-ray discs mastered in xvYCC will be watched by many consumers on TVs that do not support xvYCC – Blu-ray players will not convert from xvYCC to Rec 709 • Care has to be taken when mastering xvYCC content to ensure it looks good when displayed on a Rec 709 TV – The way that a Rec 709 TV displays xvYCC code values undefined in Rec 709 is not also not defined

Mastering xvYCC QC on xvYCC BD Master Transform display xvYCC P3 & Color Master Correction QC on Rec 709 display Notes: Rec • P3 is the color space for digital QC on Rec iTunes cinema and all theatrical content Transform 709 709 display Master is mastered in P3 Master • Rec 709 is the standard color space for HDTV • The xvYCC color space is larger than Rec 709 but smaller than P3

Content protection for 4k

Work in progress

DRAFT Content Delivery for 4k

Use Cases 1. Electronic Sell Through (EST) – Consumer purchases title through Online Account – Consumer downloads content to any device registered to Online Account – Device transparently obtains playback license DRAFT – Consumer plays content 2. Physical media with on-line activation – Consumer purchases title on physical media – Registered device responds to media insertion and adds to consumer’s Online Account – Device transparently obtains playback license – Consumer plays content – Directly from physical media – From copy on registered device

Use Cases 3. Physical media without on-line activation – Consumer purchases title on physical media – Consumer plays content directly from physical media DRAFT – Consumer cannot copy content, must have physical media – Requires different content protection scheme 4. Streaming – Consumer purchases title (ownership or rental) through Online Account – Device connects to streaming provider using Online Account – Device transparently obtains playback license – Consumer streams content to any authorized device

Physical Media Offering • Many consumers want to buy physical media with an electronic copy – Studios bundle a Blu-ray disc with a digital offering (e.g. UV, bonus digital copy, AACS managed copy, etc.) DRAFT – Studios are selling 2 copies for the price of one – Consumers keep the disc and use the digital offer  – Consumers keep the disc and sell the digital offer  – Consumer use the digital offer and sell the disc 

Content Delivery • Use the same file format for download and physical media – Standardized file format such as the Common File Format (CFF) – Physical media and download are just two different ways to get the 4k file to the consumer DRAFT • Streaming with industry standard MPEG-DASH – Uses a file format that is similar to CFF • SPE is researching 4k delivery using H.264 (AVC) as an interim codec – Initial results are encouraging – Other companies are doing similar research – H.265 (HEVC) is the long term solution but completion of standard, resolution of IPR claims and implementation may make immediate adoption difficult – However, without an upgrade path to H.265 early adopters of 4k products will be unable to get new 4k content
