Audio Signal Transmission - Example
The Concept
The matrix frame is installed with different types of I/O boards:

Inputs
The matrix can receive audio signals from two types of sources:
▪
Analog audio
from the microphone - it is converted to 2-channel LPCM signal and routed to the Audio
layer;
▪
Digital embedded HDMI audio
from the Blu-ray player - the signal is de-embedded and copied to the Audio
layer.
Outputs
On the output side the matrix can transmit two type of audio signals:
▪
Analog audio signal
to the active speakers - the transmitted audio signal can be 2-channel LPCM only.
As the selected signal can include more than two audio channels, the user can select the two channels
which are desired to transmit on the analog audio interface.
▪
Digital embedded HDMI audio
to the 4K TV - the embedded audio signal can be 2-channel LPCM or
compressed (non-HBR) audio signal only. There are two possibilities in case of audio signal embedding:
–
If the selected signal includes more than two audio channels, the user can select the two channels
which are desired to transmit.
–
If the selected signal is compressed (non-HBR) audio, it can be embedded to the video stream
without any further action.

Lightware Device Controller (LDC)
software in the
section.

Ethernet Layer
INFO:
All three Ethernet ports of matrix (
Secure Control
;
Uplink
;
Uplink/Secure Control
) are equals and they can
be used for controlling the system.
5.3.1.
Control Mode
The matrix can be controlled using the three Ethernet ports with Neutrik RJ45 connectors which provides
1 GbE data transmission per each.
The device can be controlled over the Ethernet interface using more different method. See the details about
5.3.2.
Firmware Upgrade Mode
The firmware upgrade of the matrix frame can be applied over the Ethernet interface using the Ethernet
ports.
The firmware files of the I/O boards are built in the firmware package of the matrix. The firmware upgrade
of the I/O boards can be done over the internal Ethernet layer. See the details about the firmware upgrade
procedure in the
Firmware Upgrading of the I/O Boards
section.
