When FAB Subtitler BCAST/XCD is used for live transcription with FAB Subtitler Server then the audio source can be connected to FAB Subtitler Server instead of connecting it to FAB Subtitler BCAST/XCD. This is “Remote Audio”.

Supported audio sources in FAB Subtitler Server

• Audio received from SDI: Decklink card with 1 or more SDI inputs (Decklink Mini Recorder 4K, Decklink Duo 2, …)
• Audio received from udp/rtp/srt TS/IP input
• Audio received from SMPTE 2110 input

Audio sources are defined on the “General settings” page in FAB Subtitler Server Configuration program.
