9362 Functional Description
1-8 9362 PRODUCT MANUAL 9362-OM (V4.1)
AFD Inserter
This function provides for assignment and insertion of AFD codes into the
SDI output video when program video is being passed. Using this function,
AFD codes in accordance with the standard 4-bit AFD code designations can
be applied to the output video.
This function checks for any existing AFD code within the received video
input. If a code is present, the code is displayed. When used in conjunction
with a separate downstream card capable of providing AFD-directed scaling,
the image can in turn be scaled in accordance with the AFD coding embedded
by this card.
The function also allows the selection/changing of the AFD code ancillary
data line number for the outputted AFD code.
Embedded Audio Groups 1–4 Controls
When the TSG output is invoked (either automatically or manually), all four
embedded groups are overwritten with TSG audio. As such, each embedded
channel can be set to one of four internal audio tone generators (or to silence).
Tone Generator Function
The 9362 contains four built-in tone generators (Tone Generator 1 thru Tone
Generator 4). Each of the four tone generators can be set to a different
frequency, and are available as audio sources for the embedded audio outputs.
18 discrete sine wave frequencies are available, ranging from 50 Hz to 16 kHz
(default frequency is 1.0 kHz, with a unity-gain output level equivalent to
-20 dBu).
