Connected Entertainment –
Two Perspectives
Consumers & The CE Industry
A Brief History of
Successful CE Products
Radio
VCR
TV
Cable Ready TV
Transistor Radio
CD
Walkman
DVD
What Is A Home
Entertainment Network?
It is NOT a PRODUCT
It is NOT an APPLICATION
It IS a FEATURE
Connected Entertainment Is
Not Home Networking
More Differences Than Similarities
Customer
Merchandizing
Retail Buyer
Product Life

Cost of Returns

Consumer
Expectations
Consumer Expectations
Wired or Wireless
Simple, Reliable connections
Instant Gratification: 15 minute rule
Full resolution: SD today, HD tomorrow
Coverage: Everywhere – No Excuses
Premium content
Security
In short: Connectivity plus everything their
CE products give them today
CE Industry Needs
In room connectivity
Multi-room connectivity
Agreed upon Standards
Mass Market Sales Channel
Compelling applications
In-Room Connectivity
3 Main Benefits
Reduce wire and connector
proliferation, expense, confusion
Enable features not otherwise
available or understandable
Share device resources
The Contenders:
Ethernet vs. 1394
Prediction
1394 wins the A/V connector if it achieves
Mass-Market penetration for
entertainment before Ethernet delivers
reliable and simple to use connectivity
and a solution for Ethernet CP / DRM is
accepted

Multi-room Connectivity
Requires No-New-Wires
Channel, Channel, Channel
“No Assembly Required”
A/V aisle won’t sell CAT5 or
solutions from other departments
Connectivity is a feature
Education is expensive
And so is wiring
No-New-Wires: Which Ones?
Wireless – WiFi set the table but can’t
serve the main course
Coax – The Entertainment Connector
PLC – maybe HomePlugTM v2.0
Phone - DOA
CE Industry Needs

Multi-room connectivity
Agreed
upon Standards
Mass Market Sales Channel
Compelling applications
Standards: The Consumer View
PHY/MAC – The connector is the Standard
Discovery and Addressing – Easy install
Media Formats – Ease of use
Command & Control – Remote Control
QoS – Reliability
Copy Protection/DRM – Content availability,
ease of use, …
Network Management – Customer support
(Huh?)

CEA Connected Entertainment
Initiatives
R7.5 WG8, WG1
WG8: CEA 2007 – QoS over IP/Ethernet
WG1: CEA 2005 – Network Adapter to connect 1394
(61883 streams) to Ethernet
WG3: CEA 931B – Man-Machine Interface
WG4: IP browser based interface
R7.6
CEA 2008 – Digital Entertainment Network: IP over
Ethernet
(Separating 2008 into Architecture plus interfaces)
Possible New Interfaces: 1394, wireless
CEA, Wireless and UPnP
R7.7 WG1
Wireless Networking: Mapping Apps to
Wireless HN solutions
New Work: Standardized Specs
UPnP v1.0 Referenced in CEA Standards
CEA 2008 (DENi – Entertainment over home
IP networks)
R7.4 / CEA 851 (IP over 1394 backbone)
Draft CEA 2005 – A/V Adapter
Other Initiatives With CEA
Member Support
Content Protection/DRM – PERM,
SmartRightTM, DTCP, others
IP over 1394 Isochronous channel
Isochronous Ethernet

applications
Applications Drive Sales
Media Server drives HN drives DTV drives
Server
A/V Service Providers
DSS – Levels the playing field
MSO – Moving to retail
Both provide messaging
WEB Services
Adds BB to the mix, drives convergence
Requires integrated networks for many services
Web Services and
Consumer’s Electronics
Nearly invisible Web Services
Consumer sees or uses directly
Browser based interfaces,
information augmentation
Purchasing goods & content
Gaming
Etc.
Completely Invisible Web
Services
Automatic Purchasing and
Billing
Service Bundling – 1 phone / 3
connections
Network & configuration
management, firmware updates,
security, etc.
Drivers for Web Services:
Inside the home
Entertainment
Convenience
$
Savings
Drivers for Web Services:
Beyond the home

2 Basic Approaches
1.
Existing Services
Transferred Revenue
Ex: Telephony
2.
New services
New revenue generation
Ex: Google
MYTH
Bandwidth can fix everything
Corollary: “Give me a big
enough lever and I will move the
world”
FACT: Both are true in theory,
not implementation
Wireless will always be bandwidth
challenged
Bandwidth is like processing speed and
memory – more is never enough
QoS, Guarantees are a must!!
MYTH
There will be a single unified
home network
FACT: Ignores buying habits and
market forces
People buy products one or two at a time for a
single purpose
No-new-wires will drive whole-home solutions
A/V and PC devices have different connectivity
needs
Commoditization of PC networks will keep them
separate for the next few years
To become unified
QoS and CP / DRM issues must be solved
Costs for entertainment connectivity must reach
parity with PC networks
The WiFi Highway Versus
High Speed Rail
How to move lots of freight, fast,
“When it absolutely, positively
has to get there on time”

The TDMA RAILROAD
Time Division Multiple Access
(TDMA)
Advantages
Support for Isochronous streams,
asynchronous IP/data
Improved bandwidth guarantees
Determinant latency, jitter
Enables improved RF performance
(distance/throughput)
TDMA Wireless Networks

Magis Networks’ AIR5TM
Example:
Magis Networks’ AIR5
Designed for Entertainment networks
TDMA MAC – Guaranteed QoS
10 msec guaranteed delay/jitter
PER: 10-10 after FEC
Security – 3DES, public and private key
exchange
Whole-home HDTV throughput
>30 Mbps / 3000 sq ft home
Magis

AIR5
Simultaneous TCP/IP, video, audio
802.11a phy - Coexists with 802.11
Power and Frequency agile
Adjacent Channel Utilization
Strong CE support
AIR5 SIG created to standardize
Conclusions
1.
Guaranteed payload delivered to the
application layer, at the point-of-use
is the only measurement that
counts.
Everything else is hype!
Conclusions
2. Think “Top Down”:
Consumer → Channel → Product →
Feature → Technology
