MSD Software Manual PRELIMINARY Release Chapter 6 The Extended Audio Matrix.

6.2.1.3.2 HD-SDI Audio Group selection.

Since it is possible to de-embed audio from two different audio groups in the

HD-SDI signal, the group selection has to be done in two steps. If the HD-SDI

de-embedding module in the MSD is mounted in input slot number 1, then the

module is assigned to source number 33, 34, 35 and 36 in the input selection

window in the audio matrix.

Step One: To assign a stereo pair from one of the four audio groups in the HD-

SDI signal to source #33 and #34, use the arrow [] / [] keys to move the

green selection bar to the item called ‘AUDIO GRP A’ and then press

[SELECT]. In the group selection window use the arrow [] / [] keys to

move the green selection bar to one of the four available audio groups and

then press [SELECT] to assign the group or [EXIT] to abandon the changes.

Step Two: To assign one of the two stereo pairs in the selected HD-SDI audio

group use the arrow [] / [] keys to move the green selection bar to the

item called ‘GROUP A CH’ and then press [SELECT]. From the channel select

window use the arrow [] / [] keys to select either ‘CH 1 – 2’ or ‘CH 3 –

4’.

Use the same procedure for ‘Audio Group B’ to assign a stereo pair to audio

source #35 and #36 in the audio matrix.

6.2.1.3.4 HD-SDI Input Status.

In the HD-SDI option window there are 6 status flags. The first three flags in

the list are confirmation flags.

‘Audio Processing’ – If green, the HD-SDI signal contains a valid AES

audio stream.

‘Valid Video Detected’ – If green, the HD-SDI signal contains data.

‘SDI Lock’ – If green, the HD-SDI signal is valid and the signal is locked.

The next three flags are warning flags.

‘AES Error’ – If red, the embedded AES audio stream can not be decoded

correctly.

‘CRC Error’ – If red, the HD-SDI video stream is corrupted.

‘SDI Data Error’ – If red, the HD-SDI signal might not be connected.

The warning flags in the HD-SDI option window are “sticky” flags. This means

that the displayed warning flags are not dynamically updated. When an error

occurs the corresponding warning flag is set, but it will only be cleared if the

HD-SDI option window is closed or the [CLEAR] key is pressed.

6.3 Output Options.  

Depending on the type of physical outputs in the MSD there are in the

‘Extended Matrix Window’ different options available.

To access the output options from the ‘Extended Matrix Window’ use the

[] / [] keys to move the cursor to the column ‘OUTPUT’ and then use the

use the [] / [] keys to move the cursor to the desired destination and press

the option key. If the option key is greyed out no options is available for that

particular source.
