Introduction 8

4 Introduction

The AES-VMUX is used to transport a large number of digital audio signals. The module is both
a multiplexer and demultiplexer and has 16 AES audio ports which may be used as inputs or
outputs. The module forms the core of a highly flexible audio transport and routing concept.

The audio transport has a fixed embedding and de-embedding delay of 64us. The audio signals
are transported completely asynchronously and bit transparently. The clock and phase informa­tion of each AES signal is transported along with the data and the signal is re-constructed at the
demultiplexer end. This keeps all of the AES signals time-aligned through the multiplex and pre­serves the signal phase alignment of multichannel audio.

The module encodes the audio into an SD SDTI video signal and uses the active video space in the
video frame. This allows routing and transport of the multiplex through an established broadcast
infrastructure and inspection with standard test equipment/ waveform viewers.

Modules may be daisy chained to increase the number of AES audio signals in the SDTI signal up
to a maximum of 64 AES channels.

Demultiplexing may be performed on any module from any of the audio signals in the SDTI mul­tiplex. Each demultiplex channel is, in effect, a 64 to 1 AES router.

The module may also be equipped with an SFP providing optical link capability.

Six backplane types are presently available:-

• Double width backplanes

− AES-MUX-C1; All 16 AES ports on female d-sub DB25 and dual optical connectors.

− AES-VMUX-C5; As AES-MUX-C1 but with passive relay loop-through on electrical

SDTI.

• Single width backplanes

− AES-VMUX-C1; 8 AES ports on DB25, DIN 1.0/2.3 SDTI and dual optical connectors.

− AES-VMUX-C4; 8 AES ports on DB25, BNC SDTI and single optical connector.

• Flashcase single width backplanes

− AES-VMUX-C2; 16 AES ports on Molex Male KK, BNC SDTI output only and dual

optical connectors.

− AES-VMUX-C3; 16 AES ports on Molex Male KK, BNC SDTI and single optical con­nector.

SFPs are available for:-

• APD/CWDM Transceiver (18 wavelengths)

AES-VMUX/-SFP User Manual Rev. G

Introduction 9

• PIN/Standard laser tranceiver

The following Nevion video SFPs may be used but only one of the channels will be utilised.

• PIN dual receiver

• APD dual receiver

• Standard short haul dual laser

• CWDM dual laser

The optical input provides an extra input and the actual input may be chosen automatically or
set manually to the required input. In “Auto” mode, the input switches if a suitable signal is not
present, or if the signal disappears. There is no priority, the first input with a valid Nevion SDTI
audio signal is used.

4.1 The Nevion SDTI audio concept

The Nevion SDTI audio uses a normal 625 video frame and data format. This allows simple reuse
of existing legacy infrastructure and standard test and signal monitoring facilities.
The audio is embedded into the active video area on all video lines. An extra ancillary data packet
in the horizontal blanking area identifies the signal as a Flashlink SDTI audio multiplex.

The audio embedding uses two video lines to optimize the number of channels in the multiplex.
Seven stereo audio samples, embedded over two lines gives a maximum sample rate of 54.7 kHz.
This gives a high multiplexing efficiency of normal 48 kHz broadcast audio. The embedding pat­tern repeats over a two frame sequence. The phase reference is only inserted on one of the the two
lines and a frame counter is also embedded into the horizontal ancillary data packet.

The audio is embedded in fixed timeslots placed along the video line. The phase words are embed­ded in a block of video words placed first on every other line followed by seven audio blocks. Each
audio block has 64 audio timeslots. Each timeslot contains a 24 bit audio sample together with the
C, U and V bits from the AES subframe. The frame of AES audio is split between two audio blocks.

The audio multiplex appears on a video monitor as a series of vertical lines or stripes on a video
monitor. Dark green stripes are areas where no audio is embedded. Light green shows that the
channels are embedded but that the AES input is absent. An active audio channel appears as a
multicolored vertical stripe.

The SDI embedded clock is used as a clock reference and the audio is sampled with reference to
the start of the horizontal blanking. The phase measurement (similar to HD audio) is embedded
on the following line. All of the audio channels use the same reference point and all of the phase
measurements are embedded together in a block.

Introduction 10

4.1.1 HW 1.1 enhancements

Extra VCXO to allow input locking independant of output frequency. This gives the following:-

• Wider input jitter tolerance.

• Master mode module will de-multiplex audio to its AES outputs regardless of loop status.

i.e. System is more resiliant as a module may fail but the remaining chains of modules
still present will still work.

• More stable frequency of SDTI as the output frequency will not change until full lock
is achieved. i.e. Downstream modules will not lose lock when an upstream module is
removed. Performance with the relay backplane is now much improved.

• Wander tolerance of Master mode module is much larger allowing the use of a loop across
video links which are time multiplexed or packetized.

5.4.1 Slave modules

HW 1.0 1.1

Video latency 0.56 us 0.85 us

5.4.2 Clock master module

The master module has a buffer which may be up to 2 video lines or 128 us. The actual latency
will depend on the latency due to the round trip which may be large if packetizing transports have
been used or if the stream has been received via satellite. The Clock master module will then add
as little latency as possible to round the total latency up to a multiple of two video lines. Minimum
latency is 128us.

5.4.3 Audio latency

Input to output via a single link

AES 128us / 6.145 audio samples @ 48kHz

Audio Latency will increase by the video latency every time the SDTI signal passes through a
module.

Configuration 14

Figure 6.1 Module DIP switches.

The module DIP switches must be set up correctly. The module has 16 audio ports and the first
thing to consider is the port directions. This influences all of the following steps.
The three things that must set with the DIP switches are:

1. AES port direction

2. Input port embedding start address

3. Clock master mode

Routing to the output ports may be controlled with Multicon GYDA if the ’DIP config mode’ is
off. If ’on’, the start address is set with the switches.

6.1 Clock Master

This mode is only used by one card in the system and is only necessary when the SDTI signal is
sent in a loop. A module set as clock master will not try to lock to the input SDTI signal but will
still extract the data and re-multiplex the audio in the output stream­HW 1.0 -as long as the jitter and wander in the signal is less than 1 UI.
HW 1.1 -in all cases to the AES outputs. The audio which is re-embedded into the multiplex will

AES-VMUX/-SFP User Manual Rev. G

Configuration 15

contain errors, if the wander is very large or periodically when the loop is not complete. This hard­ware version may be used for looped configurations where one or more of the module connections
is over a link where wander is present on the output signal, i.e. IP or SDH video links.

6.1.1 SW2.6 Clock Master mode

• On: Module is the clock master

• Off: Module is a clock slave

6.2 Audio port direction

The 16 audio ports are controlled in blocks of four ports. There are only 5 valid combinations and
these are set with DIP switches SW2 1-3.

6.3.1 Input addresses

The input address switches always set where the AES input signals are multiplexed.
The start timeslot used is set with DIP SW1 5-8 according the above table. The address start points
hop over 4 addresses because the AES ports are always inputs or outputs in blocks of four. The 16
combinations with 4 dip switches cover the range of addresses in the multiplex (16 timeslots x 4 =

64). The other input ports are placed consecutively in the multiplex after the start address.
The audio of these physical input ports will be available in the multiplex for all the AES-VMUX
cards in the chain, unless they are overwritten by inputs on other cards that have overlapping
multiplex addressing.

6.3.2 Output addresses

The AES output signal routing may be set by the DIP switches in DIP mode, or with the Multicon
GYDA system controller.

The signal routed to the first AES output port comes from the timeslot set with DIP SW1 1-4 if the
DIP config mode switch is on/up.
The other physical output ports have signals consecutively in the multiplex after this address.
The output port addressing may be individually controlled by the Multicon system controller if
the DIP config mode switch is off/down.

AES-VMUX/-SFP User Manual Rev. G

Configuration 18

6.3.3 System address planning

The number of timeslots in the multiplex used by the module depends on the number of input
ports in the module.

It is up to the user to ensure that the addressing is consistent and timeslots are not overwritten
(unless this is intended).

6.4 Method

1. First define the port directions on each module.

2. Arrange each site so that the modules with de-multiplexing channels come first in the
SDTI chain.

3. Assign the addresses to the modules with multiplexing channels.

4. Assign the addresses to the modules with de-multiplexing channels.

Most configurations will be simpler than the last two examples here.

• On: Optical input is used

• Off: Electrical input is used

6.7 DIP configuration mode

The AES output port routing and the SDTI input switch control may be controlled by the system
controller and stored in the module. The AES input routing and the AES port directions parame­ters are always controlled with the DIP switches.

6.7.1 SW2.8 DIP config mode switch.

• On: The card will be configured with the DIP switches. The module will not accept com­mands from the system controller but may be monitored.

• Off: The module will be configured with the internally stored configuration and the AES
output routing and SDTI input may be controlled with FLP4 commands as listed in chap­ter 6.

As with all Flashlink modules, stored configurations in the Multicon controller will be applied to
a module that is plugged into a running system, provided that the switch SW2.8 is off and that the
last module present in the system was of the same type. A module with SW2.8 on, plugged into
a running system will overwrite the stored configuration in the Multicon controller with its own
configuration.

Errors that will be present as a result of other errors are masked out to allow the user focus to see
the most important error. i.e. If the lock error is active (red), the other errors will be green.
The block has an error counter with accumulates the number of video frames that have had errors.
The counter may be reset on the info page.
The different errors may be masked out individually by the user in order to isolate certain events.
The vmon block is configured on the conf page but the error mask is only shown after the black
’pulldown’ triangle has been clicked on. The masking effects the counter as the vmon block no
longer sees the error. Masked out errors are shown as grey blocks on the info page.
The signal integrity alarm will be triggered if the error parameters shown on the conf page are
