“Broadband Home”
•
•
Our name for “connected home”, “smart home”, “digital home”
Broadband access and in-home distribution network
– Any kind of access (DSL, cable, wireless, fiber,…)
– Any kind(s) of home networking (Wi-Fi, Ethernet, PLC, …)
•
Multiple broadband devices
– PCs, TVs, phones, game consoles, … and emerging appliances
•
High speed
– Megabits: Millions of bits per second
– To the home, in the home and from the home
•
“Always on” connection
– Continuous connection
– From the home to the outside world, and to the home from the
outside
•
“The Extended Home”
– Includes the back yard, the garage, the car,…

Issues With Our Home Devices and Wiring
• “Islands” communicate poorly -- or not at all
– No way to move baseband video and audio (e.g., DVD player
output) from one room to another
– DVRs can’t talk with each other
– Camera and camcorder plugged into a single PC at a time
– Weak control over lighting
– No connection to HVAC
• Many things we wish we could do but can’t
– Record movie on one DVR and play in another room (could do it if
they were same brand) -- needs both media and control solution
– Monitor and control lighting and HVAC from outside house
–…
• Lacks ease of use and ease of administration
– Incredible level of complexity both in trouble shooting and
whenever we want to do something “a little different”

Networking Issues
Photo sharing
Digital camera
None
Music (Rhapsody):
Multimedia PC
Networking of speakers
Digital movies
Digital camcorder
Files too big to share
Internet on TV:
Networked media player,
(e.g. Prismiq)
Box needed for each TV;
Quality
TV on demand (DVR
DVRs with big hard drives
(e.g., TiVo, ReplayTV)
Need DVR for each TV;
sharing only with DVR
from same manufacturer
Broadband telephony:
MTA+Analog phones
(e.g. Cisco 186 for Vonage)
SIP phones
Quality; Vonage/186
only supports one line;
weak service support for
SIP phones
(Shutterfly): Upload many
photos; create projects
Always-on streaming
downloads
(Videowave): Create
videos to load on Website
When TV is closest device
capabilities): TV programs
we want, when we want
Inexpensive phone calls,
new capabilities

What’s The Problem For Service Providers?
• Providing broadband access is only the starting point
• Broadband connected in the home to multiple flavors of
– Personal computers
– Home wiring/networks
– CE devices, e.g. TVs, phones, digital cameras and camcorders
– and more …
• Mix of legacy analog and new digital devices
• All affect the ability to address consumer’s home
• CE and PC industries jockeying to leverage broadband to
their advantage
– Who gets what part of the consumer revenues?
– Both creating software/devices to supply (IP) telephony
• Challenges
– Dizzying rate of change from CE & PC industries
– Complexity of home environment
– Cooperation/competition with other industries
– Threat to traditional voice revenues

Slide 11
What Will the Home Architecture Be?
• Simple environments may be addressed by a centralized
solution
– Example: Computers, home networking, connecting digital camera
to one computer
• More typical complex home environments better addressed
through distribution of function
– Every attempt to put many complex functions in single centralized
unit has failed due to Moore’s law (cost and rapid obsolescence)
– Leverage, don’t fight the efforts of PC and CE industries
– Take advantage of the PC -- biggest source of horsepower and
flexibility in the home
• Example of distribution of function
– “Gateway” device including router for connection to broadband
– Use resources of PCs (control, storage, communications) when
present
– Use PVRs (standalone or set-tops) to store media content
– Network PC and CE devices with IP, Ethernet and UPnP

Our Conclusions For Service Providers
• Try to solve manageable pieces
– Risk of doing too much: all-in-one solution likely to be late to
market, overly expensive, quickly obsolescent
– Risk of doing too little: contending forces dominate and BSP
becomes dumb pipe; core voice business continually eroded as
VoIP develops
• Find the right balance: what provides best value for customer
and best value add for service provider
– “Attempting the impossible is not good strategy; it is just a waste
of resources.” (Bruce Henderson, BCG)
• CableHome is MSO attempt to find this balance
– Goal: “extend high-quality, managed, value-added broadband
services to subscribers over any available home network”
– Although video is MSO core business, first versions address the
“simpler” data environment
– CableHome 1.0 starts with basics: Firewall management, address
translation, gateway management, device visibility
• Learn from/cooperate with other industry
efforts
– DHWG and CEA’s DENi (The Digital Entertainment Network
Initiative -- CEA-2008).
