1.5 Prerequisites/Preconditions

This protocol operates between a protocol client and a protocol server that is identified by a URL that is known by protocol clients. The protocol server endpoint is formed by appending "/m/met/Participant.svc" to the URL of the site, for example: http://www.example.com/m/met/Participant.svc

This protocol requires that a broadcast session be started and in progress prior to joining it. Broadcast sessions can be started using the Office Broadcast Presentation Service Protocol as defined in [MS-OBPRS].

This protocol requires that files being used in broadcast sessions be identified and accessed as specified in [MS-WOPI].
