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

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

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

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

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.

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
