
Content Directory




Rendering Control


Control rendering characteristics (Volume, Brightness, …)
Connection Manager



Browse/search Content Items and Containers
Include content meta-data (title, creator, resolution, …)
Manage content (e.g. create playlists, add new items,…)
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
Typical Control Algorithm
Discover AV devices
Locate desired content
Negotiate a common
transfer protocol and data format
Control playback position/movement
Control how content is rendered

“Charter 2”
Approved
Scope of Work – Charter 2

Maintain existing specs


Publish Recommended Practices docs



E.g. Better compatibility checking (resolution, sample rates…)
Add New Features


Provide implementation guidelines
Many common devices (TV, VCR, CD/DVD Player, stereo, …)
Enhance existing features


Clarify ambiguous text, add additional examples
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
Logistics – Charter 2



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

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”
Goals

Maintain existing AV specs

Publish Recommended Practices

Enhance existing AV features

Enable new AV features

Maintain backward compatibility
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)
Enhancements

Improve existing features

Examples:




