Web GUI Control
1/1553-FGC 101 1790 Uen Y 5-47
Parameter Values Description
Coding Mode 1/0 (Left – input), 1/0 (Right – input), 1/0 (L+R)/2,
2/0, 3/2L (5.1 Surround)
Specifies what channel configuration to use for encoding.
Embedded PCR On, Off Controls whether PCR is to be embedded in the audio
PES.
Au Information Cont Off, AU Info
Controls the insertion of private data in the adaptation unit
of the audio access units (AU). AU Info is defined in ETSI
TR 101 154. Only AU_PTS is present for audio
Encapsulation MPEG-2 ADTS, MPEG4 LATM/LOAS Specifies the encapsulation used for transmitting AAC
content. It can be either MPEG-2 Audio Data Transport
Stream or MPEG-4 Low Overhead Audio Stream based on
MPEG-4 Low Overhead Audio Transport Multiplex.
TNS (Temporal Noise
Shaping)
Off, On Turns noise shaping on or off.
SBR Signalling Explicit, Implicit Specifies how Spectral Band Replication is signaled.
Advanced
Lip Sync Offset -500 to 500 ms Configures a delay to the audio to improve A/V
synchronization.
Gain -6 to 6dB Sets the gain in dB for the audio stream.
Language The language of the stream.
User Language 1 A custom three-character language code when User
Language 1 is set in the Language field.
User Language 2 A custom three-character language code when User
Language 2 is set in the Language field.

Parameter Values Description
Embedded PCR On, Off Controls whether PCR is to be embedded in the audio
PES.
Au Information Ctrl Off, AU Info Controls the insertion of private data in the adaptation unit
of the audio access units (AU). AU Info is defined in ETSI
TR 101 154. Only AU_PTS is present for audio.
Channel Mode 2 channel (stereo / dual mono) LPCM pass-thru will always pass thru both channels
present in the incoming AES3 stream.
Bit Depth 16-bit, 20-bit, 24-bit Select the expected bit depth of the audio words. This will
affect the outgoing elementary stream bit rate.
Channel Identification 0 - 255 User defined channel identification number of the first
audio channel in the outgoing SMPTE 302M
stream’sAES3 data header.
Advanced
Lip Sync Offset -500 to 500 ms Configures a delay to the audio to improve A/V
synchronization.
Gain -6 to 6dB Sets the gain in dB for the audio stream.
Language A selection of languages from across the world. The language of the stream to be signaled in descriptors.
Audio Stream Type Main Audio; Clean Effects; Hearing Impaired;
Visual Impaired
Intended use of the audio.
