Scope of Work
Maintain existing specs
Publish Recommended Practices docs
Better compatibility checking (resolution, sample rates…)
Improved recording control
New Features
Implementation guidelines
Common devices (TV, VCR, CD/DVD Player, audio player, …)
Enhance existing features
Clarification of ambiguous text, additional examples
DRM/CP, scheduled recording, multicast, access control
Backward compatible with existing specs
Based on UPnP V1 Device Architecture
Existing actions/state variables will remain unchanged
Logistics
