Introduction
This slide set contains draft material for tutorial on possible solutions to different aspects of the architecture
The slide set is intended to be discussed in the TG1 and reviewed by the group
The slide set will be updated as needed; frequent updates are expected as per comments received
Rev0 of the slide set is just the list of items that are proposed to be covered by this part of the tutorial

3. Possible solutions to different aspects of the architecture
May 2010
Possible solutions to different aspects of the architecture
Proposed topics CE
Request and obtain information, required for coexistence, from TVBD network or device
What information we need from TVBD networks and devices?
How do we get the information?
Translate reconfiguration requests/commands and control information received from the CM into TVBD-specific reconfiguration requests/commands and send them to the TVBD network or device
What are the possible coexistence mechanisms?
How they are used in various TVBD networks?
How do we interface to various TVBD networks? CM
Coexistence decision making
Support exchange of information required for coexistence among CMs
How to exchange coexistence information between decision making entities?
