  1. Approaches to Home Connectivity T-109.7510 Research Seminar on Telecommunications Business Marko Berg

  2. Agenda • Background for Home Connectivity • Exemplary Use Case Scenarios • Current Technologies • Universal Plug and Play (UPnP) • Digital Living Network Alliance (DLNA) • UPnP and DLNA in the Market • Conclusions • Questions

  3. Need for Home Connectivity • Technological advances • Picture and voice quality • Network bandwidth • Connection options • Communication mechanisms and mobility • Resulting in more devices and new functions

  4. Need for Home Connectivity (2) • New ways of acquiring content • Over the Internet • From local network • Cameras • Audio and video recording devices • Broadcast systems • Resulting in the need to transfer content between several devices

  5. Need for Home Connectivity (3) • Technical solutions exist for most problems • Discovery of devices in the network • Connecting over different types of networks • Transferring images, audio and video • Storing and sourcing media in a network • The issue is one of interoperability and transparency – standardization needed

  6. Exemplary Use Cases Case 1: Image Display from Multiple Sources

  7. Exemplary Use Cases (2) Case 2: Video Service Mobility

  8. Exemplary Use Cases (3) Case 3: Central Media Source

  9. Current Technologies • Zeroconf • Bonjour by Apple • Jini • Java technology • Universal Plug and Play (UPnP) • Digital Living Network Alliance (DLNA

  10. Universal Plug and Play • Standards developed by UPnP Forum • Est. 1999 • More than 800 members • Designed as a interoperable M2M, P2P protocol • Independent of network, protocol, language • Device-agnostic – mobile, fixed, CE, PC, ... • Platform-independent, for virtually any purpose

  11. Universal Plug and Play (2) • Defines Device Control Protocols (DCP) in six device categories • Audio/Video • Home Automation • Networking • Printer • Remoting • Scanner

  12. Universal Plug and Play (3) • Protocol functionality • Addressing • Discovery • Description • Control • Eventing • Presentation

  13. Digital Living Network Alliance • DLNA is an industry consortium • Est. 2003, more than 200 members • Develops guidelines for home connectivity • Home environment seen as three islands of devices • Consumer Electronics • Mobile Devices • PCs and Peripherals

  14. DLNA (2) • Use cases used as a basis for guidelines • Use cases built on technology-independent needs – not likely to change soon • Accepted standards and practices used • Not necessarily open, but accessible

  15. DLNA (3) • Guidelines define building blocks for implementation • Technologies defined for all parts of interconnection • Network technology • Device discovery • Media transport • Content formats • Communication protocols

  16. DLNA (4) • Three device categories • Home Network Devices • Mobile Network Devices • Home Interoperability Devices • Targeted only to home environment • Future extensions possible

  17. UPnP and DLNA in the Market • More UPnP devices • Longer availability • Suitable for more specific purposes • Devices available in all DLNA categories • More promotion by the consortium • DLNA also targets consumers

  18. Conclusions • Establisment of DLNA might indicate deficiencies in UPnP • UPnP leaves a lot up to the implementations • Interoperability might remain partial and focused • DLNA provides a heavier, but also more comprehensive solution • Impressive support from the industry • Might have better chances in the long run
