Home Networking
U.S. Cable Perspective

ITU-T Workshop on Home Networking and Home Services
Tokyo, Japan, 17-18 June 2004
Why Home Networking?
ITU-T
o Home networking goes with broadband
• 50 to 60% of broadband customers have home
networks (The Home Network Market: Data and
Multimedia Connectivity, Parks Associates, March 2004)
o It is more than just Internet Access Sharing
• It is also multimedia distribution throughout
the home (New connections for the Broadband
household, CTAM, May 2003)
• 40% of broadband customers want to share audio over
the home network
• 36% of broadband customers want to share video over
the home network

Important Issues For Cable
ITU-T
o The important issues for cable in deploying
multimedia home networks:
• Quality of Service (QoS) guarantees
• Content protection (aka Copy Protection or
Digital Rights Management)
• Content discovery and navigation
o These issues cannot be addressed without a
secure, managed home network
o CableLabs has developed the CableHome™ to
provide the secure, managed home network
foundation

CableHome™ Evolution
ITU-T
o CableHome 1.0 (Basic Internet Connection
Sharing)

o CableHome 1.1 (Advanced Internet Connection
Sharing)
• Specification first issued in April 18, 2003
• ITU Recommendation J.192
• 3 certified CableHome 1.1 products to date
o CableOffice (Commercial Gateway Device)
• Specification first issued on March 24, 2004

ITU-T
US Regulatory Issues for
Multimedia Home Networks
o Cable Operators in the US must comply with
specific regulatory requirements for set-top
terminals and consequently multimedia home
networks
o The 1996 Telecommunications Act mandates
the “retail availability of navigation devices”
or set-top terminals
o The FCC issued its Navigation Order in 1998
detailing these regulations
o This resulted in July 2000 Point-of-Deployment
(POD) Modules for removable security

US Plug-And-Play Agreement
ITU-T
o Throughout 2002 – One-way Negotiations
between Cable and Consumer Electronics
Manufacturers
o December 2002 – Memorandum of
Understanding (MOU) reached between Cable
and Consumer Electronics Manufacturers
o OCTOBER 2003 - FCC 2nd Report and Order
establishes MOU as regulation, sets stage for
Two-way Negotiations
o 2004 - Two-way Negotiations include all
interested parties (Cable, CE, DBS, Content…)
dates

ITU-T
Elements of the
Plug-And-Play Agreement
o Interface specification, based largely on the
OpenCable specs as standardized in SCTE
o Defines “Encoding rules” to embody a
structure for use of digital copy protection
o Consumer labeling, not another round of
cable-ready TV confusion
o Foundation for two-way agreement on a
common software platform (OCAP) and rules
for how CE devices can support full range of
cable interactive services and applications

Encoding Rules
ITU-T
o Protects content according to the
release window
dates
Copy Never
Copy Once
Copy Freely
Pay-Per-View
(PPV) and Videoon-Demand
(VOD)
Programming
Premium
Subscription
Services (e.g.
HBO) and
Expanded Basic
Re-transmitted
Terrestrial
Broadcast TV

reality
CableHome (ITU) specifications provide the
foundation for these secure, managed
networks
US Cable Operators must comply with FCC
regulations regarding Plug-and-Play
The two-way negotiations will involve higher
value, Copy Never content (VOD and PPV)
Content Protection and DRM are key issues
