UPnP AV Services

• Content Directory
• Browse/search Content Items and Containers
• Include 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 connections
• AV Transport
• Control playback position/movement (Play, Pause,
  Seek,)
• Provided by Server or Renderer based on selected
  protocol

Scope of Work Charter 2

• Maintain existing specs
• Clarify ambiguous text, add additional examples
• Publish Recommended Practices docs
• Provide implementation guidelines
• Many common devices (TV, VCR, CD/DVD Player,
  stereo, )
• Enhance existing features
• E.g. Better compatibility checking (resolution,
  sample rates)
• Add New Features
• E.g. DRM/CP, scheduled recording, multicast,
  access control
• Preserved backward compatibility w/ Charter 1
  CPs
• Based on UPnP V1 Device Architecture
• Existing actions/state variables will remain
  unchanged

14
Logistics Charter 2

• Target Timeline
• Facilitate quarterly plugfests
• Preliminary Design (Ver 0.8) - Nov 03
• Design Complete (Ver 0.9) - Feb 04
• SC approval of specs (Ver 1.0) - May 04
• At least 5 sample implementation commitments
• Co-Chairs
• Intel and Philips (John Ritchie, Geert Knapen)

• Volume, Mute, Loudness
• Presets

23
Connection Manager Service

• Negotiate protocol/format
• GetProtocolInfo()
• PrepareForConnection()
• Discover existing connections
• GetCurrentConnectionIDs()
• GetCurrentConnectionInfo()

24
AV Transport Service

• Select desired content
• SetAVTransportURI()
• SetNextAVTransportURI()
• Control contents movement/position
• Play, Stop, Pause, Seek, Record, etc.
• Next Track, Previous Track (e.g. playlists)

25
Architectural Summary

• AV Devices
• MediaServer, MediaRenderer
• Combo devices (including a Control Point)
• AV Services
• Content Directory
• Rendering Control
• Connection Manager
• AV Transport
• Simple Control Point Algorithm
• Find content, configure devices, transfer data

26
What is it?

• Follow-on to UPnP AV Charter 1
• Based on current UPnP Device Architecture
• Unrelated to UPnP V2 Architecture
• Think of it as UPnP AV Version 1.1

27
Goals

• Maintain existing AV specs
• Publish Recommended Practices
• Enhance existing AV features
• Enable new AV features
• Maintain backward compatibility

28
Maintenance

• Clarify ambiguous text
• Improve certification tests
• If needed, address critical bugs
• Examples
• XML and URL escaping, Connection Info usages
• Recommended Practices docs for several common
  devices e.g. TV, VCR, stereo, CD changers, etc.
• Add semantic test(s)

29
Enhancements

• Improve existing features
• Examples
• Better compatibility checking
• Better support for playlists
• Better recording capability
• Additional CDS meta-data tags e.g. owner,
  history, etc

30
New Features

• Complement existing features
• Add key missing capabilities
• Examples
• DRM, Content Protection
• Scheduled recording
• Support for multicast
• Access control (UPnP Security?)

31
Backward Compatibility

• V1 Control Points can use V2 devices
• Existing actions/state variables unchanged
• New actions/state variables added to existing
  services
• New services added to existing DCPs
• New DCPs

32
Timeline

• Written proposal to SC Aug 02
• SC approval for WC - Sept 02
• Recommended Practices docs Q2 03
• Preliminary Design (Ver 0.8) - Aug 03
• Plugfest 1 (AV V1/V2) Aug 03
• Plugfest 2 (AV V1/V2) Oct 03
