  2. Agenda • Part I: Home API Overview • Home API Working Group • What is Home API? • Home API and Universal Plug and Play, 1394 • Summary • Part II: Home API Architecture

  3. New Product Opportunities The time is ripe to move home automation and control into the mainstream Home devices are becoming “intelligent” Home/consumer networking and connectivity are “hot” People are actually beginning to “get it” Both the PC and CE industries need to find new areas to innovate - markets for current products are becoming saturated

  4. Possibility For 2000Windows PC or STB as Integration Point for Intelligent Home • Internet • External Info • EPG • weather, traffic • community Pager Telephone New apps enabled by integration of information and connectivity to controllable home devices enhances family safety, comfort, and convenience. Remote Home Access and Event Notification Phone line Home Mgt. Apps • Home State • scheduled events • house mode • config info DTV DVCR DSS DVD Digital A/V Networks (1394) Cordless basestation PC Fridge Pad Video Camera Cordless communicator Data Networks (Cat5, Phoneline RF, PLC) Control networks (PLC, RF, IR) Security HVAC Light Control Sprinkler System Sensors

  5. But: Will My PC Crash My House? Absolutely not! • PCs enhance home device functions with added intelligence • Devices must still work standalone • Should use dedicated controllers for critical tasks

  6. Current Software Approach “X” Company “Y” Company “Z” Company • Monolithic • Not easily extensible to new protocols • Vendor Specific • No published APIs for ISVs PC GUI PC GUI PC, voice GUI Lighting andSmall Appl Control App Security, HVAC Control App Security, Lighting Small Appl., CE Control App. RF SensorDrivers X-10Drivers X-10Drivers X-10Drivers IRDrivers Proprietary, non-extensible solutions don’t grow the market.

  7. A Better Approach: Home API • API designed for control of Home Devices • No new protocols • No new networks • First implementation under Windows

  8. Home API Working Group • Founded Q4 ’97, went public Q4 ’98 • Now 31 participants • 0.95 Spec released to participants December ’98 • http://www.homeapi.org

  9. Home API Working Group Promoter Companies

  10. Who Are The Participants? • An influential group of companies interested in enabling new product opportunities in the home automation, control, and networking area • A diverse group of companies, with hardware and software expertise, representing: • PCs, software applications, and peripherals • Consumer electronics and entertainment • Home HVAC and security • Home lighting • Home automation and control

  11. Agenda • Part I: Home API Overview • Home API Working Group • What is Home API? • Home API and Universal Plug and Play, 1394 • Summary • Part II: Home API Architecture

  12. The Home API Is… • A service running in Windows • Allowing for discovery, and control of home devices by Windows applications • Network and protocol agnostic • A framework for device namespace • A runtime for installable home “behaviors”

  13. The Home API Is Not… • A network management service • Directly involved with Media Streaming • But, can be used to locate media streams associated with devices in the home

  14. Home API Services • Object creation • With discovery and control • Property routes • State change propagation • Events and subscriptions • Update on demand • Containers • Context, behavior encapsulation • Associations • Expose related components • Asynchronous operations • Efficient, failure tolerant

  15. Home API Discovery And Control • Standard COM/OLE automation interfaces • Simple, centralized namespace for devices • Regardless of connectivity method • Notification of new devices and services added to the system • Network and protocol agnostic • Network or bus connectivity model left to Service Providers

  16. Namespace FrameworkFor home control devices and services • Designed to mirror home topographies • Scope devices to actual locations in the home • E.g.,“home.den.light” Home Living Room Den TV Light Light Phone

  17. Runtime For Installable Home Behavior • Home’s “Behaviors” can be contained completely in the Home API process • Use “Routes” to describe a relationship between two objects properties • “mySwitch.Power - myLight.Brightness” • More on this in next talk

  18. Home API Architecture Client Application • Layered • Extensible via installable • “Service Providers” Home API X-10 Service Provider 1394 Service Provider “Cool New Stuff” Service Provider

  19. Service Providers • Service Providers supply object instances to Home API • E.g.. MyLightSwitch • Home API supplies wrapped instances to clients • Clients may be other Service Providers • E.g., Scene managers, Smart Containers

  20. Service Providers • Implement COM classes that expose: • IHomeControlObject • IpersistPropertyBag • Hides network interface details • Matches events to subscriptions • For event signaling • Responsible for adding and removing Home API objects as devices come and go • Must handle hot Plug and Play

  21. Agenda • Part I: Home API Overview • Home API Working Group • What is Home API? • Home API and Universal Plug and Play, 1394 • Summary • Part II: Home API Architecture

  22. Home API And Universal Plug And Play Windows Home Applications Home API Universal Plug and Play Service Provider IP Home Networks Using HomePNA, Ethernet, Wireless, 1394, etc. Internet E.g., Broadband shared via NAT IP-based devices and services Directly connected and proxied

  23. Home API And IEEE 1394 Windows Home Applications Home API UPnP Service Provider Non-IP 1394 Service Providers AV/C, HAVi, etc. IP over 1394 IEEE 1394 1394 Devices

  24. Home API And HAVi • Easily extensible for Home API • Complementary to Home API • HAVi devices available to Home API Home API Home API to HAVi Service Provider HAVi

  25. Home API To HAVi Service Provider • Tracks devices on 1394 network • Installs/Removes objects to HAPI • Installs DCMs in HAVi devices as needed • Interacts with other HAVi components HAVi Device Home API Application 1394 Home API HAVi Service Provider COM

  26. 1394 To IP Gateway • Gateway in Set Top box or similar device • ARP, RARP equivalent • Work with “legacy” TCP/IP Network also • SNMP support • Cooperates with HAPI Service Provider IP Home API PC 1394/IP Gateway 1394 Ring

  27. Agenda • Part I: Home API Overview • Home API Working Group • What is Home API? • Home API and Universal Plug and Play, 1394 • Summary • Part II: Home API Architecture

  28. Home API Summary • Open industry effort, 31 participants to date • Service provider architecture for home automation • Network and protocol independent • Complements Universal Plug and Play, HAVi, and other device control models • Leverages PC intelligence for more flexible, simpler home control scenarios • Without making home devices dependent on PCs • Begin planning migration from proprietary APIs now www.homeapi.org
