SCENARIO FOR THE FUTURE

THIS IS WHERE WE SHOULD BE IN 20 YEARS TIME……

Smart Homes with home electronic systems have become the “must have” in the market – everybody has one!

Multiple manufacturers supply the market

Everything has a processor in it, everything can communicate and multiple systems and protocols can be used

We have entertainment systems (a/v, multi-media etc.) and they all work together and link into the Future Internet and you can have whatever entertainment whenever you want it

BUT we also have

Energy Management systems saving energy by monitoring everything that uses energy

Telecare and Health systems looking after the elderly at home

Physical security systems keeping us safe

BUT we also have

Home Automation systems running the house and looking after lighting, windows, doors ..

PC and IT Systems linked to A/V and helping us work from home

Domestic Appliance Systems being monitored for optimum working efficiency

So what’s the problem we have a €600 Billion per

annum market we have a digital society every entertainment source

is at our fingertips

Well ………

Any home will have multiple systems that will share the same physical media

No two homes will have quite the same mix of systems, services, networks, media

Installers, vendors and consumers fit equipment on an ad-hoc basis

0.1% of consumers may know what is installed

0.0001% may understand how it all works together

90% of homes will have some sort of home electronic system

Worldwide there may be up to 1 Billion of such homes by 2027

Multiple interoperable systems need management and it is not trivial

Go to office comparison CLICK

We have to find ways to use automatic systems to manage Smart Homes – we do not have the people to do it

We need Interoperability and Management Frameworks that allow existing systems to interoperate

We need self healing software, firmware, hardware, networks and devices

We have to have totally reliable systems or systems that degrade gracefully – some applications will be life critical

We have to get it right now before the mass market gets under way

And we don’t have much time left.

The market appears to be growing at different speeds in various sectors. But there is probably no “killer application” or “killer sector” that will drive the market. We will probably not see people installing SmartHouses specifically.

What we will see is a total soup of networks, physical layers, applications devices objects etc growing with time. CLICK

Sectors that are most likely to accelerate the growth are:EntertainmentEnergyHealth and Care (Assisted Living) at home

Sectors that are least likely to start the growth are:Building IndustrySecurity Alarm IndustryAppliancesBut they will be implicated as soon as the other sectors start their growth

But we will want to use devices, systems, applications, from any of these sectors

Regardless of what network or protocols they may use.

We need to understand what they do, how they do it and everything about them

So what does the A/V, Networked Media, Entertainment sector have to do with all this?We have

DLNA, UPnP, IGRSHANADVB, ITU, ETSILON, Konnex, BACNet, and a whole lot more including proprietary solutions

Providing all the answers ….

The Entertainment system has a key role in providing the user information conduit to and from all the other smart systems in the digital home

An Energy Management system will need to monitor every energy using device in the home. A part of the “energy” solution is telling the consumer what is being used.Another part is control

A Telecare system will need to use A/V systems to provide communication between carer and patient and may have other roles. It may want to know information from the energy system and from the security system

A Home Control system will need to have an easy to use interface for setting the environment.

A door entry system will need to show who is at the door and have controls to open the door to welcome visitors – displayed on the TV, PC or even the Mobile phone

Domestic Appliances will be monitored to keep them working in perfect condition and it will be possible to send alerts to the A/V system

What characterises almost all sectors is that any interoperability work is related to the sector only.The possibility that services for one sector may need to know what is happening in another one is avoided.

What is INTEROPERABILITY?“The ability of two or more entities to communicate and co-operate despite differences in the implementation language, the execution environment and/or the model abstraction”

What is INTEROPERABILITY?“The ability of any service, application or object to communicate with any object or device in any sector or system and to be able to utilise it (appropriate to the object) for its own use.”

A key requirement is they may all need to work together

there may be necessity for priorities between applications.

A typical application may check the window open sensor and turn off the radiator and report to the TV or PC

Or the Smart Meter may tell the fridge the current demand for energy and get it to switch off temporarily

CENELEC SmartHouse

Complexity and Chaos

Each sector is working on interoperability

many applications need to use resources from many sectors

every home will be different different stakeholders will provide /

pay for / “own” different components. (permissions, priorities, micro payments

etc.) (knowing what is already installed – what

it does and who owns it)

CENELEC SmartHouse

Complexity and Chaos

The net result is a situation of Convergence: multiple systems in the

home High levels of variability and complexity Available systems, applications and

components not visible to other systems Often QoS or integrity of information is

uncertain Service levels not guaranteed.

In other words unless we can do something about the situation – CHAOS

We need standards for Interoperability that apply ACROSS sectors

CENELEC SmartHouse

SmartHouse Interoperability and Standards – Recap.

Most standards for equipment in the SmartHouse standardise within that equipment type

Interchangeability rather than interoperability interoperability between similar equipment in

networks and communication Most Standardisation in the Home does not

cover interworking with different product types or sectors

Some sectors have specified Interoperability within their sectors (DLNA, IGRS, UPnP, HANA, DVB, ETSI/ITU, CECED, KNX, LON, . . . . . . . )

However, convergence will require that devices and systems in different sectors shall work together

CENELEC SmartHouse

What is needed

An Interoperability Framework Standard plus a set of sector standards covering: Interoperability principles and definitions Protocols Co-existing with all (or most) existing work Use Cases?

Authority / legitimacy Independence Open systems – that everyone can buy into – especially

industry. Government/Industry sponsorship

Use Cases

CENELEC SmartHouse

Interoperability Framework Standard The Application Home Initiative (TAHI) has

been working in this area for 6 years. Trials, Market surveys and Industry WGs Developed TAHI Open Architecture concept (used

in TEAHA, MonAMI projects) TAHI launched an Interoperability Framework

Standard project at its Forum in London in February

Supported by an Interoperability Framework Initiative

NSB managed, CENELEC Workshop Agreement with CENELEC TC205 WG16 as the recipient WG.

CENELEC SmartHouse

What is an Interoperability Framework

A simple set of high level, cross sector operating rules.

For example:

Convention on the International Regulations for Prevention of Collisions at Sea

ISO 9001…

(LCD – Lowest Common Denominator)

Actually, there is a narrow margin between a pragmatic set of rules and an over specified standard. The standard must be compelling rather than intrusive.

CENELEC SmartHouse

Outlines of Framework

TOA suggested 6 main requirements1. Understanding of service supply

chain2. Identification of Objects3. Service Agents4. Declaration5. Application Models6. AbstractionDetail

Semantic Web, IP, Web 2.0 Middleware etc.

CENELEC SmartHouse

Objectives

To turn the TAHI Open Architecture Framework into a NSB led CENELEC Interoperability Framework Standard for Europe by start of 2009

Use a CENELEC Workshop Agreement fast track process to gain widespread consensus

Unlock the potential for smart technology to deliver significant market growth, energy savings and social benefits in the home within 5 years

CENELEC SmartHouse

What is TAHI?

Not for profit organisation owned by its members with (moral) support from BERR

Aim: “to accelerate the adoption of products and services by connected home-based users”

Activities: Understanding industry/sector drivers –

barriers, opportunities for Members (and wider industry)

Forums Working Groups – Industry sector – esp:

Health/Telecare, Energy, Built Environment, Technology/ interoperability

Providing information to members (and wider audiences)

CENELEC SmartHouse

Project Support

The project has been whole-heartedly approved by the TAHI Board

It is fully supported by the current TAHI membership

The Initiative is attracting new members to help pay for the work: Microsoft, CISCO, STM, Honeywell, ARM, Centrica and others are thought to be considering TAHI membership

• Government funding will encourage participation & membership

CENELEC SmartHouse

Smart Home systems will be much more varied than your offices. In the office you have skilled IT specialists who keep the office working . . . . ?

In the home you

CENELEC SmartHouse

Checking the integrity of the security system

Fault in the security system - house closing down

System error the house will reboot in 20 seconds

Ring 08 70 33 34 44 4 for support services (calls cost €15,00 per minute)

Communication systems closing down

Don’t panic!

Don’t panic . . . . . . . . . . . . . . . . help!

In the home you DON’T have any IT support

If we don’t have real INTEROPERABILITY making everything work together

This will be a major BARRIER to market growth

We are not there yet! We simply cannot have the Smart Home “crashing”.

Go BACK

potentially 450 Million Smart Homes across Europe with multiple systems, multiple devices - maybe 1 Billion World-wide

More than just Entertainment

As we have seen the Entertainment sector is more than it seems it entertains – and that is complex enough it will provide information it will display information it will be one of a number of interfaces for

providing control to systems in the Smarthouse

other sectors need it as an interface This convergence leads to complexity

ENTERTAINMENT is not the ONLY system in the digital home

it uses energy • so we may need to measure and

control energy use community and telecare systems

may need to use it for communicating with people.

other systems use the same media

we may need to link with entry and security systems

Elements

CENELEC SmartHouse

CENELEC Workshop Agreement

An informal European standard Typically is maintained for 3 years then

renewed or transformed into a formal European or ISO Standard.

A proven and inclusive procedure that involves all interested parties in a series of workshops

Normally facilitated by a Standards Body which provides the required independence

A typical CWA would take around 5 workshops and 6 – 12 months to agree.

CENELEC SmartHouse

Why TAHI?

TAHI members have been working on interoperable open architectures to facilitate interoperable services and applications for many years – developed the TAHI Open Architecture (TOA)

Cross sector interoperability is now urgent and must have a set of standardised rules. (It is a market barrier)

Market size: probably upto One Billion smart homes world-wide needing interoperable systems in the next 5 years

TAHI needs TSB funding to prepare the standard and promote it when it has been published

CENELEC SmartHouse

Proposed Plan

Stage 1: Project Definition Establish Steering Group and Project Team Scope and cost project and establish governance Raise sponsorship Select Standards body to run the CWA

Stage 2: CENELEC Workshop Agreement Facilitated by Standards Body

Stage 3: Implementation The Framework is implemented by Sectors using it to

shape their own standards The Initiative would promote, encourage and provide

advice on implementing the framework
