7. Edit While Playout
7.1. Introduction
7.1.1. General Description
Purpose
The Edit While Playout mode allows the users to play out a timeline in IPEdit while editing
the same timeline in the same instance of the IPEdit application.
• The timeline editing is performed on the IPEdit engine PGM3/4.
The "edit timeline" is called the TLE.
• The timeline playout is performed on the IPEdit engine PGM1/2 or on a single channel
supporting the "Mix on one channel" functionality.
The "on-air timeline" is called the TLO.
The on-air timeline is updated by applying the editing actions performed on the TLE to the
TLO, via a COMMIT button.
This is possible to use the EWP mode (Edit While Playout mode) in a Master/Slave
configuration, so that it offers a failover mechanism in a redundant setup.
User Interface
Introduction
Both TLE and TLO are managed on the same instance of IPEdit, and are visible on the
same Timeline display. The TLE editing is performed as usual with the commands above
the Timeline display. The TLO playout and related actions is managed via dedicated
commands, displayed on the EWP Control Panel:
