Input
Format Uncompressed (LPCM), MPEG Layer II, Dolby Digital, Dolby Digital Plus,
Dolby E, AAC. Sets the input format used by the audio encoder.
Source Off, Mute, Test Tone, Embedded 1 to 8. Sets the source used by the audio
encoder. No input is fed to the encoder if Off is selected. Mute mutes the
incoming audio and encodes silence. Test Tone encodes an 1 kHz test tone,
Embedded 1 to 8 sets the source to an SDI embedded audio stream.
Output On Audio Loss No PID, Silence. Specifies the action to take when input is Lost. No PID is for
dropping the audio PID from the stream, Silence is for encode silence.
NOTE: When No PID is selected, the reference to the PID is not removed from
the Program Map Table, so a Transport Stream analyzer will indicate a ghost
PID in the output Transport Stream.
