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

  6. UPnP™ AV ArchitectureUPnP 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. UPnP™ AV ArchitectureTypical Control Algorithm (Playback) Discover AV devices UPnP™ SSDP Locate desired content Content DirectoryService Identify a common transfer protocol and data format Connection ManagerService Initiate and control the transfer AV TransportService Rendering ControlService 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 4th field of “protocolInfo” • New features • Automatic recording of content available in the future • Support for premium (DRM protected) content • Changing AV Renderers
