Timecode Processor
(See Figure 1-3.) This function provides for extraction of timecode data from
the input video, and in turn re-insertion of timecode data into the output SDI.
The function can monitor analog and SDI video streams, and audio LTC over
a selected channel, for supported timecode formats and then select and
prioritize among analog VITC, SDI VITC, SDI ATC_VITC, SDI ATC_LTC,
and audio LTC timecode sources. Audio LTC can be received over a selected
balanced analog audio input, or as digital audio over a selected embedded or
AES input. If the preferred format is detected, the preferred format is used by
the card; if the preferred format is not detected, the card uses other formats
(where available) as desired.
The function also provides conversion between various timecode formats and
provides independent insertion and line number controls for each SDI
timecode output format.
Option +LTC allows bidirectional transfer and conversion
between VBI formats over SDI and audio LTC, as well as RS-485 LTC.
Audio LTC can be received or sent over a selected balanced analog audio
input, or as digital audio over a selected embedded or AES input.

Introduction 932X Functional Description
Audio Processor Description
(See Figure 1-2.) The audio processor operates as an internal audio router.
The router function chooses from the following inputs:
•16 channels of embedded audio from the SDI video
•16 channels (8 pairs) of discrete AES input (9321, 9323 only)
•8 channels of balanced analog audio input (9321, 9323 only)
•Four independent internal tone generators (described below)
•Digital silence (mute) setting
•Internal down mix and mono mixer outputs (described below)
•(+DEC only) Decoded Dolby®channels
The router function provides the following audio outputs:
•16 channels of embedded audio on the SDI output
•16 channels of discrete AES output on eight AES pairs (9322, 9323
only)
The router acts as a full audio cross point. Each of the output channels can
receive signal from any one of the input channel sources, four internal tone
generators, or the Down Mix Left and/or the Down Mix-Right mixer outputs.
Unused output channels can be mapped to a “Silence”source. Each output
also provides gain adjustment and selectable polarity inversion.
(+DEC only) In addition to the audio sources described above, the up to 10
decoded Dolby®channels are available as input sources.
Output audio rates are always 48 kHz locked to output video, but discrete
AES inputs can pass through the sample rate converters to align these inputs
with the output timing. (AES must be nominally 48 kHz input; 32, 44.1, 96,
and 192 kHz inputs are not compatible with the card.) The sample rate
converters are disabled by default. Output AES is always precisely
synchronized with the output video. The balanced analog audio input is
sampled at 48 kHz with a +24 dBu clipping level (+24 dBu => 0 dBFS).
Note: As shown in Figure 1-4, the 9322 and 9323 are equipped with eight discrete
AES input pair ports and eight discrete AES output pair ports. On Rear I/O
Modules having limited AES I/O capabilities, switches S11 thru S14 allow
available rear module BNC connectors to be allotted between AES inputs and
outputs as desired. Buffered copies of AES OUT (1-4) are available as dedi-
cated outputs and as respective outputs fed through S11 –S14 on the card.

Audio Down Mixer and Mono Mixer Function
(See Figure 1-5.) The Audio Down Mixer function provides for the selection
of any five embedded, AES discrete, or analog audio sources serving as Left
(L), Right (R), Center (C), Left Surround (Ls), and Right Surround (Rs)
individual signals to be multiplexed into a stereo pair (Down Mix Left (DM-L)
and Down Mix Right (DM-R)). The resulting stereo pair DM-L and DM-R can in
turn be routed and processed just like any of the other audio sources described
earlier.

Introduction 932X Functional Description
The Mono Mixer function (Figure 1-6) generates an additional mono-mixed
channel from two selected embedded, AES discrete, or analog input channels
serving as left and right inputs. The resulting mono mix channel MONO can in
turn be routed and processed just like any of the other audio sources described
earlier.
Figure 1-6 Audio Mono Mix Functional Block Diagram with Example Sources
2.0-to-5.1 Upmix Function
Note: Upmix function is an optional licensable feature. This function and its controls
appear only when a license key is entered and activated. (This option (identi-
fied in Cobalt®price lists as +UM) can be purchased upon initial order, or
field-activated using a key string which is sent to you when this option is pur-
chased.)
The 2.0-to-5.1 upmixer function receives a normal PCM stereo pair from the
Audio Routing/Gain Control function and upmixes the pair to provide 5.1
channels (Left (L), Right (R), Center (C), Low Frequency Effects (LFE), Left
Surround (Ls), and Right Surround (Rs)). Whenever the upmixer is active, it
overwrites the six selected channels with the new 5.1 upmix signals
(including replacing the original source stereo Land Rinputs with new L and
R signals).
The 2.0-to-5.1 upmixer can be set to up mix in any of three modes: Always
upmix, Bypass upmix, or Auto enable/bypass upmixing. The Auto upmixing
mode looks at the signal levels on the selected channels and compares them to
a selectable level threshold. It then determines whether or not to generate 5.1
upmixing from the stereo pair as follows:
•If the upmixer detects signal level below a selected threshold on all
four of the selected channels designated as C, LFE, Ls, and Rs, this
indicates to the upmixer that these channels are not carrying 5.1. In
this case, the upmixer overwrites all six selected channels with the
new 5.1 content.
•If the upmixer detects signal level above a selected threshold on any
of the four selected channels designated as C, LFE, Ls, and Rs, this
indicates to the upmixer that the channel(s) are already carrying
viable 5.1 content. In this case, the upmixer is bypassed, allowing the
original channels to pass unaffected.

The examples in Figure 1-7 show the automatic enable/disable up-mixing
function applied to example selected channels Emb Ch 1 thru Emb Ch 6. As
shown and described, the processing is contingent upon the signal levels of
the channels selected to carry the new 5.1 upmix relative to the selected
threshold (in this example, -60 dBFS). Note also that this function is applied
after the Audio Routing/Gain Control function. Because all audio inputs pass
through the Audio Routing/Gain Control function before the up mixer, the up
mixer can use embedded, AES discrete, and/or analog audio sources.

initial order, or field-activated using a key string which is sent to you when this
option is purchased.)
If your card was purchased with option +LP, loudness processor manual
supplement “5.1 and Stereo Loudness Processing Options for Compass®
Cards (+LP51, +LP20) Manual Supplement”(OPT-SW-LP-MS) is included
in your documentation package. Supplement OPT-SW-LP-MS can be
downloaded from our website or requested using the Cobalt contact
information in this manual.
Tone Generator Function
The card 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 or AES audio
outputs.
18 discrete sine wave frequencies are available, ranging from 50 Hz to 16 kHz
(default frequency is 1.0 kHz).
Audio Routing Example
Figure 1-8 shows an example of using the 9323 audio embedding/
de-embedding and routing functions to de-embed audio, route the audio to
discrete outputs for post-production processing (in this example, a console
used for post-production EQ, levels, and monitor), and finally re-embed the
audio into the SDI video output. Additionally, the example shows how
external analog sources can be embedded into the SDI output (in this
example, a provision for local station ID voice-over analog).
Note that the source and destination correlations shown here are only
examples; any source can route to any destination.

AES Sample Rate Converter
The card AES inputs have sample rate converters that can be independently
enabled for each AES pair to allow the card to interface with asynchronous
AES sources (sources in which AES timing does not match the video input
timing). The sample rate converters are set to disabled (bypassed) by default;
this is necessary when embedding undecoded, non-PCM audio such as
Dolby®E or Dolby®Digital™audio streams. When a valid Dolby®E or
Dolby®Digital™signal (in accordance with SMPTE 337M) is detected on an
AES or embedded audio signal, SRC is automatically bypassed along with
gain and polarity controls.

Introduction 932X Functional Description
Zero-Delay Audio Embedding
In cases where additional delay must be avoided, it may be desirable to embed
AES with minimum latency. Using zero-delay embedding, the video can then
be delayed by one frame to account for any remaining audio delay. In this
manner, any delay between video and audio can be cleanly contained and
managed within one frame period.
When zero-delay audio embedding is enabled for a given AES pair, the pair is
directly embedded into its corresponding group (for example, AES Pair 1 into
embedded channels 1 and 2; AES Pair 2 into embedded channels 3 and 4, and
so on) with the normal frame sync audio delay being bypassed.
This function overrides the audio routing system (for example if AES Pair 1 is
selected, then the controls to route AES Pair 1 into other embedded channels
will not apply). Gain and polarity control is not available when this option is
selected. Zero-delay audio embedding is set to Off by default.
Low-Latency AES Passthrough
This function is similar to zero-delay audio embedding. If low-latency AES
passthrough is selected for a given input pair, it causes the corresponding
AES output pair to act as a bit-for-bit copy of the corresponding AES input
pair. This control overrides the normal audio routing and delay. Gain and
polarity control is not available when this option is selected. Passthrough is
set to Off by default.
Dolby®Decoding Option (+DEC)
Note: Although the +DEC Dolby®decoder-equipped cards can provide Dolby®Digi-
tal™(AC-3) decoding, discussion and examples here describe only Dolby®E
decoding.
When Dolby®E or Dolby®Digital™is present on a discrete AES pair or an
embedded audio pair, the decoder produces up to 10 decoded channels
(according to the Dolby®sub-format received from the metadata). All
resulting channels are available as inputs to the audio router.

Dolby®Identification and Metadata Output Processing
(See Figure 1-9.) All AES pairs and embedded channels are checked by the
+DEC card for valid Dolby®status. When a valid Dolby®encoded embedded
or discrete AES pair is detected, the channel pair carrying the Dolby®format
is displayed as “Present Dolby E”or “Present Dolby Digital”, as applicable.
(The decoder always uses the metadata associated with its respective AES or
embedded pair.) A selected encoded channel pair can then be directed to the
Dolby®decoder. The decoder then displays the Dolby®bitstream format and
program configuration (for example, “Dolby E 20-bit 5.1+2”indicating
5-channel surround with LFE channel and stereo monitor pair) for the
selected pair, as defined by its metadata.
The +DEC card can embed metadata on the SDI output, sourced from either
SDI input video or from the decoder as desired. Similarly, the DOLBY META
output can provide RS-485 metadata for downstream devices or systems.
Metadata on the DOLBY META RS-485 output can also be sourced from either
SDI input video or from the decoder as desired.
Audio Decoding
(See Figure 1-9.) Based on the channels carrying the Dolby®encoded pair and
the format defined within, the Dolby®decoder provides up to 10 decoded
audio channels (Dolby Ch 1 thru Dolby Ch 8; Dolby Mix 1, Dolby Mix 2). Each
channel can be routed just as any other audio channel described in this
section.
