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

Consumer Expectations
More Differences Than Similarities
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 NeedsIn room connectivityIn room connectivity Multi-room connectivity
Agreed upon Standards
Mass Market Sales Channel
Compelling applications
3 Main Benefits
Reduce wire and connector proliferation, expense, confusion
Enable features not otherwise available or understandable
Share device resources
In-Room Connectivity
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
In room connectivityMulti-room connectivity
Agreed upon StandardsMass Market Sales ChannelCompelling 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

Compelling 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

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

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

Conclusions
1.1. Guaranteed payloadGuaranteed payload delivered to the application layerapplication layer, at the point-of-usepoint-of-use is the only measurement that counts. Everything else is hype!Everything else is hype!
Conclusions
