Adtec digital RD-70 (version 1.02.04) Manual - Manual (Page 53)

Note: Encoder must support alignment for aligned audio feature.
The RD-70 automatically configures the audio engines upon acquisition of a program when
engines and sdi matrix are configured to ‘AUTO’. The audio is automatically output based
on ascending audio PID order from the selected program, not PMT order, to retain encoder
compatibilities. The left hand status panel of the Web UI shows current active SDI audio
output. Advanced configuration is available via the Audio tab for users that need to select
custom PID’s, disable audios, and duplicate audio pairs.
Dolby E line placement is handled automatically to meet Dolby Labs specification. Some
users may need custom line placement. If the customer Dolby E line placement selection is
out of specification, the RD will revert line placement to the automatic in range value.
Please see
table in notes for Dolby E line placement recommendations.
Notes:
● Encoder must support alignment for aligned audio feature.
● Pass-through audio bit-rates are now displayed on the left hand status panel. Please
note that these are live calculated bit-rates and will not show a static number.

AFD - Active Format Description
Active Format Description (AFD) contains aspect ratio and handling information utilized to
aid in picture presentation of downstream devices. This is used most often by down-
converters and set top boxes.
AFD carriage can be carried within a transport stream as a unique ANC PID (ancillary pid),
within the video elementary stream as SEI data (H264), or user data (MPEG2). The RD-70
does not support AFD via an ANC PID at this time.
