2 Overview UPnP™ AV Architecture (v1.0) v2.0 Extensions Demo Questions

3 UPnP™ AV (v1.0) Architecture (Completed June 2002) Content Distribution (a.k.a. Playing available content anytime, anywhere)

4 UPnP™ AV Architecture Content Playback Scenarios Various User Scenarios  Watch a video on a television  Listen to music on a stereo system  Show digital photos on (Electronic Picture Frame) One Common Theme  Content on Device A  Rendered on Device B  Control remotely by user Browse - Select - Play

5 UPnP™ AV Architecture Device Interaction Model (Playback) Control Point Home LAN Standard UPnP Actions Out-of-band Transfer Protocol Standard UPnP Actions Media Server Media Renderer VCR Camcorder STB Digital Camera TV MP3 Player EPF Speakers Stereo Clock Radio PC DVD Player CD Player Tuner PC Content Directory Connection Manager AV Transport (Optional) Scheduled Recording Rendering Control Connection Manager AV Transport (Optional)

6 UPnP™ AV Architecture UPnP AV Services (Playback) Content Directory  Browse/search content items and containers  Includes content meta-data (title, creator, resolution, …)  Manage content (e.g. create playlists, add new items,…) Rendering Control  Control rendering characteristics (volume, brightness, …) Connection Manager  Enumerate supported transfer protocols and data formats  Enumerate existing UPnP AV streams AV Transport  Control content movement/position (play, pause, seek,…)  Provided by Server or Renderer based on selected protocol

7 Discover AV devices UPnP™ SSDP Locate desired content Content Directory Service Identify a common transfer protocol and data format Connection Manager Service Initiate and control the transfer AV Transport Service Rendering Control Service UPnP™ AV Architecture Typical Control Algorithm (Playback) Control how content is rendered

8 UPnP AV Architecture v2 (Started January 2003)

9 UPnP™ AV v2.0 Highlights Full backward compatibility with UPnP AV v1.0  Existing v1.0 Control Points still work with new V2 devices Editorial clarifications to existing v1.0 functionality  CDS::ImportResource()  CM::PrepareForConnection(), ConnectionID=0 Various improvements to many v1.0 features.  Standardized usage rules for the 4 th field of “protocolInfo” New features  Automatic recording of content available in the future  Support for premium (DRM protected) content  Changing AV Renderers

10 UPnP™ AV Architecture EPG-based Content Creation (a.k.a. Recording programs that will be available in the future)

11 UPnP™ AV Architecture Device Interaction Model (Recording) Control Point Home LAN Out-of-band Transfer Protocol Standard UPnP Actions Connection Manager AV Transport (Optional) Media Server Media Renderer Content Directory Scheduled Recording

12 UPnP™ AV Architecture UPnP AV Services (Recording) Scheduled Recording Service  Create individual recording schedules  Each “Record Schedule” generates one or more “Record Tasks”  Browse current Record Schedules/Tasks  Modify current Record Schedules/Tasks  Updated status event to interested Control Points

13 UPnP™ AV v2.0 Specifications Projected Schedule “Preliminary Design Complete” status (v0.80)  November 2004 “Design Complete” status (v0.90)  December 2004 Final adoption  Q1 2005

14 Moving Forward UPnP™ AV v3.0  Start defining AV v3.0 content in January 2005 Continue to grow UPnP™ AV v1.0/v2.0 momentum  Periodic Plugfests 2 to 4 times per year  Next Plugfest in Q2 ’05 – Location TBD Getting Involved  UPnP™ AV WC mail list:  Participate in the next Plugfest  Telecons: Twice per week (Tues and Thurs)  Face-to-Face meetings: Every 4 to 6 weeks Individual contacts:  John Ritchie (Intel) at  Geert Knapen (Philips) at
