Approaches to Home Connectivity

T-109.7510 Research Seminar on Telecommunications Business

Marko Berg

agenda
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
need for home connectivity
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
need for home connectivity 2
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
need for home connectivity 3
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

current technologies
Current Technologies
  • Zeroconf
    • Bonjour by Apple
  • Jini
    • Java technology
  • Universal Plug and Play (UPnP)
  • Digital Living Network Alliance (DLNA
universal plug and play
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
universal plug and play 2
Universal Plug and Play (2)
  • Defines Device Control Protocols (DCP) in six device categories
    • Audio/Video
    • Home Automation
    • Networking
    • Printer
    • Remoting
    • Scanner

    • Presentation
digital living network alliance
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
dlna 2
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
dlna 3
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
dlna 4
DLNA (4)
  • Three device categories
    • Home Network Devices
    • Mobile Network Devices
    • Home Interoperability Devices
  • Targeted only to home environment
    • Future extensions possible
upnp and dlna in the market
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
conclusions
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
