Approaches to Home Connectivity T Research Seminar on Telecommunications Business Marko Berg

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 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) 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) 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

Exemplary Use Cases Case 1: Image Display from Multiple Sources

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

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

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

Universal Plug and Play Standards developed by UPnP Forum Est 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) Defines Device Control Protocols (DCP) in six device categories Audio/Video Home Automation Networking Printer Remoting Scanner

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

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) 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) 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) 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 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 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
