4k Content Delivery Sony Pictures Technologies

Introduction 4k is a new opportunity for Sony, consumers and content providers 4k is a “green field” for all stake holders No legacy 4k devices The studios will set a high bar for content protection for 4k This presentation is only about 4k HD and SD versions of content continue to be offered, delivered and protected by existing means

4k Ecosystem

Consumer Experience Options for delivery Download, play on any capable device Purchase physical media, play on any capable device Stream to any capable device Store content on device and in the cloud Don’t need physical media to play content Play on any capable device TVs, set top boxes, BD players, home media servers, PCs, laptops, tablets Output to any capable screen Down-res transparently to non-4k devices Any Online Account can be shared with the family

Studio Requirements A new approach to security Different from AACS and BD+ New compliance & robustness requirements AACS compliance & robustness is based on rules from the last century Designed and reviewed by organizations expert in security, e.g. NDS, Farcombe, Merdan Single content protection system 3rd party device certification Active monitoring and response Renew security with every download or with every title Hardware protected video path Hardware root of trust e.g. Intel Insider, properly implemented TrustZone HDCP 2.0 only Verance watermark detection Playback license tied to consumer’s Online Account Forensic watermark traceable to consumer’s Online Account

Content Delivery Common container for download and physical media DECE Common File Format (CFF) Physical media and download are just two ways to get the file to the consumer Streaming with MPEG-DASH DECE Common Streaming Protocol (CSP) Uses CFF Adaptive streaming Adaptive sub-sampling as well as compression Two codecs allow for early deployment H.264 and also H.265 when available Will H.264 work? Vendors are claiming very efficient encoding.

Use Cases Stand alone physical media Consumer purchases title on physical media Consumer plays content directly from physical media (Consumer cannot copy content, must have physical media) Physical media using Online Account Registered device responds to media insertion, checks if content license is unused and adds to consumer’s Online Account Device obtains playback license Consumer copies file to any device registered to their Online Account

Use Cases EST Streaming Consumer purchases title (ownership or rental) through Online Account Consumer downloads content container to device registered to Online Account Device transparently obtains playback license Consumer plays content on any device registered to their Online Account Streaming Device connects to streaming provider using Online Account Consumer streams content to any device

Consumer Offering Increasingly consumers do not want to buy physical media without an electronic copy With HD and SD the only way to give the consumer both physical media and electronic copy is to sell them a DVD or Blu-ray and bundle a digital offering (UV, bonus digital copy, AACS managed copy, etc.) 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  4k must be a single copy per sale Effects implementation of delivery on physical media

Principles for new content protection Issue with current systems Mitigation for 4K Software systems are vulnerable Hardware protected systems only allowed (Intel Insider, Trust Zone) Permanently offline players cannot be authenticated, revoked or updated 4K security architecture will require online authentication, renewability/revocation and update checks Self-certification allows lazy OEMs through Mandatory 3rd party certification of 4K devices Single, long-standing security architecture gives hackers time to attack, and means that attacks have high impact, if successful (as whole device base is vulnerable) 4K security will be renewable, at least for each Title (preferably each download), at a system and individual device level, and support diversity across devices and Titles HDCP 1.4 is vulnerable HDCP2.0 only allowed, with backward compatibility turned off Existing compliance robustness rules are outdated and too broad New robustness rules, for devices with hardware security only and cognoscente of threats, will be developed Systems allowing multiple content protection systems are only as strong as the weakest system A single, renewable, content protection system only will be allowed

The Consumer’s Online Account Consumer offering works with their Online Account For example: Ultraviolet, iTunes, SEN Video Unlimited or Disney Key Chest Registers consumers and manages accounts Records content rights in digital library Handle device registration Hands out content licenses to registered devices Actively monitors for breaches Pushes security updates

SPE Recommendations Proceed swiftly to set the market rather than waiting for the market to respond Leverage existing (delivery) technologies Common File Format (CFF) Common Streaming Format (CSF) - MPEG-DASH H.264 with the option to adopt H.265 Proven independent* commercial content protection system, e.g. NDS Avoid vendor lock-in for delivery Allow for extensibility e.g. new codecs Content is bound to consumer’s Online Account Devices are registered to consumer’s Online Account *Not owned or managed by format participants

Action Plan Test H.264 compression for 4k Native 4k footage shot on F65 and on film Agree interface specifications with Sony TV group Partner with CE/IT company that can prototype a proof of concept set-top box HDCP 2.0 protected HDMI 1.4 output Software player running in protected hardware environment 24fps 4k content Select, or at least short list, content protection vendors In fall demonstrate streaming over fiber to the home network Or cable if data rate allows (dependent on outcome of H.264 testing) At CES demonstrate playback of downloaded file and from Blu-ray data disc
