OTTCON 2012: Content Rights and Standards: The Multi-Network, Multi-Screen Evolution Comes of Age, Petr Peterka, Verimatrix

Two themes are dominating the discussions at video service operators worldwide:

the evolution of security requirements for multi-network, multi-screen delivery systems and,
the impact of MPEG-DASH as a standardized streaming delivery protocol.

Solving thorny and complex content rights issues and implementing industry-wide standardized streaming protocols are essential for delivering high quality over-the-top and multi-network, multi-screen services. The discussions surrounding these issues are a positive sign that video service operators are poised to deploy more sophisticated and high quality services. Although consumers will not likely be aware of the changes in the back-end infrastructure this session will examine a range of solutions that will enable video service operators to offer consumers a winning combination of a less confusing and fragmented array of device capabilities, and a broader range of content choices.

  3. 3. • Analog Conditional Access Systems• Digital Conditional Access Systems• Embedded vs. Smart Card solutions• Two-way IP Conditional Access• Digital Rights Management• Output protection and home networkingIncreased contact value and quality => increasedsecurity requirements
  4. 4. • Linear TV -> PPV -> DVR• On-demand Services -> Network DVR -> Cloud Content• Electronic Sell-Through -> Rental -> Subscription VOD• Day-and-date release -> Early Release/Premium VODBusiness models and user expectations are changingrapidly
  5. 5. • One-way cable, satellite and terrestrial networks• Two-way IPTV networks• 3G/4G/LTE distribution• Unmanaged OTT networksThe goal is to reach as many subscribers over anynetwork on any device
  6. 6. • Set-top box -> DVR -> Residential GW – Custom built, single-purpose devices, integrated security• PC/Mac -> Smart phone -> Tablet -> Game consoles – Retail distribution, multi-purpose devices, limited security• Connected TV and Connected Blu-ray players – Retail, single-purpose moving to multi-purpose devicesControl over a device is shifting from the networkoperator to the consumer
  7. 7. • Initial OTT services were underestimated – Low-value content, low quality and resolution – > limited security• Consumer acceptance drives demand for high-value content and higher quality (HD) – > higher security requirementsContent value comparable to Pay-TV content demandscomparable content protection
  8. 8. What is Content Protection? – Content encryption – Authentication – Secure key management – Rights management – Output control – Link protection – Forensic watermarking
  9. 9. 1. Premium VOD – Strong encryption, robustness rules, protected outputs (HDCP, no analog), forensic watermark2. Home Entertainment/Electronic Sell-Through (EST) – Strong encryption, AACS-like, analog sunset3. PPV/Subscription VOD – Strong transmission encryption, DRM for downloads, copy- once outputs4. Free-to-air – DRM for downloads
  10. 10. Challenges in multi-network/multi-device environment: – Streaming vs. persistent download/recording – On-line vs. Off-line consumption – Smartcard -> cardless security – Software obfuscation, white-box crypto, integrity checking, … – Secure SoCs, TrustZone – Device robustness rules
  11. 11. Deter Piracy – Enhance Revenue Security• Address the challenges of digital video distribution – Especially for “early release window” HD and Premium VOD• Assist in fighting illegitimate content distribution – Act as a strong piracy deterrent – Change consumer perception of “free” content• Complementary to the use of CAS/DRM systems – Extending the security perimeter via a layered approach Copyright © 2007-2011 Verimatrix, Inc. 11
  12. 12. • From a single-network solution: – IPTV or DVB – STB -> DVR -> Whole-Home DVR• To a multi-network solution: – DVB live services augmented by IPTV on-demand• Augment managed network distribution with unmanaged network/OTT distribution – Reach mobile and tablet devices – Reach beyond physical network boundaries
