1. 4k Content Delivery
Sony Pictures Technologies

2. 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

3. 4k Ecosystem

4. 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

5. 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

6. 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.

7. 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

8. 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

9. 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

10. 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

11. 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

12. 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

13. 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
