1.1.2. Limitations
The EWP mode (Edit While Playout mode) has the following limitations:
• When the editing actions on the TLE have been committed to the TLO, it is not
possible to undo the commit. The user has to undo the editing actions in the TLE and
to re-commit to the TLO.
• All modifications are applied and committed for the future only, not in the past.
1.1.3. Channel Assignment
Two timeline engines are required to use the Edit While Playout mode: one for timeline
editing and another one for timeline playout.
The availability of the EWP mode and the assignation of channels among both timeline
engines will depend on the number of EVS server channels and the use of channels with
‘Mix on one channel’.
Several situations can occur. They are described in the next sections.
EVS Servers with 6 or 8 Channels
With a 6- or 8-channels EVS server, PGM3/4 are used as timeline engine for timeline
editing and PGM1/2 are used as timeline engine for timeline playout.
If PGM1 is a normal channel, both PGM1 and PGM2 will be needed as timeline engine for
timeline playout.
If PGM1 supports the ‘Mix on one channel’ functionality, it will be sufficient for use as
timeline engine for timeline playout. So, PGM2 will be free and could be used for any other
purpose.
EVS Servers with 4 Channels
The Multicam application running on a 4-channels EVS server must have 3 player
channels.
PGM1/PGM2 will be used as timeline engine in IPEdit, for the TLE. Then, the EWP mode
will be available only if PGM3 is a ‘Mix on one channel’. In this case, PGM3 is used as
timeline engine for the TLO.
