6 The main Player
6.1 Introduction
In Channel Composer, Objects such as ‘Clip’, ‘Audio’ and ’Still’ use a Player to play out content.
Players can be used to control playout. Different actions can be defined. The default is: Play. Players
can be modified in the Object and Objects window.
One main Player can be active per Channel.
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.
