Digital Home Overview

UPnP Technology Overview UPnP Forum has Over 730 members 6 active Working Committees, plus the Technical, Legal, and Steering Committee 12 completed device standards ( Internet Gateway Device/Access Point MediaServer/Media Renderer Printer/Scanner Basic Device UPnP Implementers Corp has Over 55 members Over 120 certified products HVAC/Lighting Controls Device Security Remote UI QoS

DLNA Standards DLNA ( is focused on delivering an interoperability framework of design guidelines based on open industry standards to complete the cross-industry digital convergencewww.dlna.org DLNAv1 regroups many existing standards (UPnP, HTTP, Audio and Video formats) into a single document that insures that home devices will interoperate UPnP and UPnP/AV are important parts of building any DLNA solutions DLNA v1.0 UPnP DLNA

DLNA DMP UPnP AV Control Point HTTP Client Media Renderer DLNA DMS UPnP AV CDS Device HTTP Server Media Server Media Transfer UPnP Discovery Media Playback DLNAv1 defines a DMP (Digital Media Player) and DMS (Digital Media Server) A DMP is a UPnP/AV CDS control point that can discover media on the network and render it. A DMS is a UPnP/AV CDS device, that makes media available to the network. DLNA v1.0 Defined Media Server & Player

Some of the Authoring Tools for UPnP Technologies Allegro ( Allegro Software offers a variety of UPnP technology toolkits as part of the extensive family of RomPager embedded Internet and Web technology. The RomPlug embedded UPnP technology toolkits run on any RTOS and use the Allegro Web and XML technology to provide embedded devices UPnP and DLNA support. Intel ( The Intel Authoring Tools for UPnP Technologies, updated to comply with DLNAv1, are freely available on the Intel web site. Source code can be used for commercial use without fees. Intel Device Builder application uses service descriptions and information provided by the user to generate very efficient, custom tailored stack.
