vxYCC color for 4k and HD 4/7/15Sony11 Pictures Confidential

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 4/7/15Sony12 Pictures Confidential

Physical media without on-line activation – Consumer purchases title on physical media – Consumer plays content directly from physical media – Consumer cannot copy content, must have physical media – Requires different content protectionDRAFT 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.) – Studios are selling 2 DRAFTcopies 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 • Streaming with industry standard MPEG-DASH – Uses a file format that is similar to CFFDRAFT • 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
