1 Scope Word‑p. 5
This document specifies the functional model, procedures and information flows needed for the mission critical video (MCVideo) service. Support for both MCVideo group streaming and MCVideo private streaming operating in on-network and off-network modes of operation is specified.
The corresponding service requirements are defined in TS 22.280, and TS 22.281.
The present document is applicable primarily to mission critical video service using E-UTRAN access based on the common functional architecture for mission critical services defined in TS 23.280 and the EPC architecture defined in TS 23.401.
The MCVideo service can be used for public safety applications and also for general commercial applications e.g. utility companies and railways.

4 Introduction
The MCVideo service supports video media communication between several users (i.e. group call), where each user has the ability to gain access to the permission to stream video in an arbitrated manner. The MCVideo service also supports private calls between two users.
The MCVideo architecture is based on the functional architecture for mission critical communication services defined in TS 23.280.
