3.1.1.7 Reserved switches
DIP switch 9 is reserved for future use and should be in the OFF position. DIP switch 10
chooses programming or run mode and should always be in the ON position.

3.1.2 Monitoring and control of ADC-SDI with Gyda

The Gyda controller card receives information about the configuration and the operating
status of the card. The displayed information includes:

Slot label (set on configuration page)

Firmware and FGPA versions

Input video mode

Input status

EDH generation status

Field 1 marking status

Filter mode

Alarms

The configuration page allows control of the following configuration parameters

Input configuration.

Enable/ disable EDH.

Enable/ disable Field 1 marking.

Filter selection.

Card label.

3.2 Audio (AAV-SD-XMUX)

The XMUX embedding core can be considered as an 18x14 stereo audio router and a 5x4
group router.

The group router is used to transport or shuffle groups without introducing any additional
delay.

The inputs or sources in the stereo router are from the de-embedded audio groups, the AES
and analog audio inputs, the delay line outputs and the two built in generators.

The stereo router outputs or destinations are the groups of embedded audio in the output
video, the AES outputs and the delay line inputs.

A normal de-embedder configuration would route the de-embedded audio to the AES
outputs.

A normal embedder configuration would be to route the audio inputs to the appropriate
embedder group outputs.

The AAV-SD-XMUX module can do both at the same time!

Many other configurations are possible and the module may be dynamically controlled as an
18x14 audio router via the system controller, GYDA.

Full control of the module is performed with the GYDA system controller. Controls only
possible with GYDA are:

The data transmission parameters and channel selection.

The output processing of each stereo signal (LR, RL, LL, RR, MS, Sum, ØLR, LØR).

The delay lines delays and routing.

Video and audio generator configuration.
