can be used to override the original AFD information, or when the video is being
scaled (e.g., when the input is HD and is being converted to SD).

AFD Code:

This control is displayed only when AFD Source is set to Manual AFD

Selection. It corresponds to the codes listed in SMPTE-2016-1, Table 1.

SCTE 104 Ad Insertion Triggers

The 9992-ENC is capable of extracting SCTE 104 triggers from the VANC (inserted as per
SMPTE 2010) and converting them to SCTE 35 triggers in the output transport stream:

Enable SCTE 104/35:

Check this box to enable SCTE 104 extraction. The SCTE 104

triggers are inserted in the transport stream as SCTE 35 sections.

SMPTE-2108 HDR Metadata

The 9992-ENC is capable of extracting SMPTE-2108 HDR Metadata from the VANC and insert
it in the video elementary stream as SEI messages.

Enable HDR Metadata:

Check this box to enable SMPTE 2108 extraction and insertion

as SEI messages in the video elementary stream.

SMPTE-2038 Generic ANC Transport

The 9992-ENC is capable of extracting any generic (non-specific) ANC data (both from the
VANC and the HANC) and inserting them into the output transport stream:

Enable SMPTE-2038:

Check this box to enable generic ANC extraction and insertion

using SMPTE-2038. Once checked, the following additional controls are displayed:

o

Maximum Bit Rate (b/s):

Some types of ANC data, such as VITC or LTC, may use

a non-trivial amount of bandwidth in the output. This parameter controls how much
bandwidth to reserve in the transport stream output for ANC data, for NULL-padded
CBR outputs. If the ANC data bit rate exceeds this value, packets may be dropped.
For ANC data that appears only occasionally, a bit rate of zero may be specified.
Note that the encoder measures the actual ANC rate in the transport stream and
reports it in the

Status

tab (please refer to the Encoder Statistics section of this

manual).

o

Offset (frames):

The encoder will include information in the transport stream that

enables the decoder to restore the ANC data to the exact same frame it came from.
This control allows the encoder to offset this information to a range of -5 to +5 frames
(i.e., the decoder will restore the ANC data to an earlier or later frame based on this
