Channel Composer User Manual - Channel Composer User Manual- document version: 1.6.2 - 50
To stop a Player, three options are available:
• Set an Out Point and leave the Player’s Auto-Stop at Out Point option activated (default).
• Create a separate Template with a Player Stop Action.
• Keyframe a Player Stop Action.
7.1.4 The Main Player
For each Channel, one main Player can be defined.
The main Player role has following properties:
• The main Player has priority over other Players when resources are assigned.
• If the main Player contains an embedded Closed Caption subtitle stream, this stream will be
played out. If other Clips contain subtitle streams, these streams will not be played out. In other
words, only the main Player’s subtitle stream will be played out.
• The main Player is the source for the ATC (HD) or VITC (SD) timecode signal in the SDI-output.
Only one signal can be sent out, i.e. from the main Player.
• If the main Player is a Live Player and this Player transfers VBI-data from the SDI-input, this VBI-
data will be transferred to SDI-out instead of any VBI-data generated by the K2 Edge server. This
means that VBI-data from the input such as subtitles and teletext is passed to the output 'as is'.
• The main Player role can be assigned at any point in time, but is only active if between an In and
out Point.
The main Player command is automatically added for the first Clip or Live Object that is added to a
Template.
For Join In Progress (JIP)-mode, a main Player role can be assigned for both normal and high priority
mode. Still, only one main Player will be active, depending on the JIP-mode (normal or high priority).
