Widex and DMSP

• (Per OMA BAC MAE group)
• Modalities each implemented by a user agent and
  zero or more processing engines
• Modalities governed by an IM
• In a DMSP-based architecture, the IM is on the
  device with visual modality
• The voice modality is in the network
• Voice modality is semi-autonomous to limit
  network traffic

Widex and DMSP (2)

• Widex is focused on distributing a single UA
• Uses MVC design pattern
• Model controller in Widex server
• View is on a Widex renderer, with a virtual view
  on the server
• Updates flow between real and virtual views
• Events flow from controller to view
• WIdex and DMSP seem orthogonal
