Introduction 9085 Functional Description

Video Functions Description

Video Processor

The 9085 provides full color processing control (luma gain and lift, chroma saturation, and color phase) of the output video.

AFD Inserter

This function provides for assignment and insertion of AFD codes into the SDI output video. Using this function, AFD codes in accordance with the standard 4-bit AFD code designations can be applied to the output video.

This function checks for any existing AFD code within the received video input. If a code is present, the code is displayed. When used in conjunction with a separate downstream card capable of providing AFD-directed scaling, the image can in turn b e scaled in accord ance with th e AFD coding embedd ed by this card.

The function also allows the selection/changing of the AFD code and ancillary data line number for the outputted AFD code.

Timecode Processor

(See Figure 1-2.) This fun ct ion provi de s for ext rac ti on of time code data fro m the input video, and in turn re-insertion of timecode data into the output SDI.

The function can monitor SDI video streams, and audio LTC over a selected channel, for supported timecode formats and then se le ct and prioritize among SDI VITC, SDI ATC_VITC, and SDI ATC_LTC timecode sources. If the preferred format is detected, the preferred format is used by the card; if the preferred format i s not det ected , the card us es ot her f ormats (where avail able) as desired.

The function also provi des con ver sion be tween va rious timecod e fo rmats a nd 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.

The audio processor operates as an internal audio router. The router function chooses from the foll owing inputs:

• 16 channels of embedded audio from the SDI video

• 16 channels (8 pairs) of discrete AES input

• 8 channels of balanced analog audio input

• Four independent internal tone generators (described below)

• Digital silence (mute) setting

• Internal Down Mix and Mono Mixer outputs (described below)

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 discrete AES pairs

1-8 9085 PRODUCT MANUAL 9085-OM (V4.3)

Introduction 9085 Functional Description

The router acts as a full audio cross point. Each of th e 24 out put channels (16 embedded, 16 discrete AES) can receive signal from any one of the 40 (16 embedded, 16 discrete AES, 8 analog) input channels, four internal tone generators, or several mixer sources. Unused output channels can be mapped to a “Silence” source. Each output also provides gain adjustment and selectable polarity inversion.

Output audio rates are always 48 kHz, locked to output video, but discrete AES inputs can be set to use sa mple rate converters to ali gn t hes e inputs with the output timing. (AES must be nominally 48 kHz input; 32, 44.1, 96, and 192 kHz inputs are not compatib le with the 90 85.) The sample r ate conver ters are disabled by default. Output AES is always precisely synchronized with the output video. The balanc ed analog audio i nput is sampled at 48 kHz with a +24 dBu clipping level (+24 dBu => 0 dBFS).

As set with the default settings, t he routing be tween embedded aud io channels

Embed Ch 1 thru Embed Ch 16 and discrete AES a udi o ch anne ls AES Ch1 thru AES Ch 16 is as shown in Figure 1-3. In this mode, the routing is basic 1-to-1

embedding/de-embedding for the 16 embedded and AES discrete audio channels. Other sources and/or destinations (described below) for each channel are selected using the card edge controls or a remote control system.

As shown in Figure 1-1, the 9085 and 9085 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 (1-8) are available as

dedicated outputs and as respective outputs fed through S11 – S14 on the card.

Audio/Video Delay Offset

The 9085 includes an audio/video delay offset function that allows audio/ video resyncing to compensate for an 8 msec delay induced by the loudness processing function. I deal r esync of audio i s provi ded by adva ncing t he audi o 8 msec using this function.

Note: Although similar to a framesync function, the audio/video delay has significant

limitations (as compared to a full framesync function) which should be considered when setting up and using this function. These considerations, along with the proper setup to use the 9085 audio/video delay function, are fully described in Chapter 3. Operating Instructions.

Audio LKFS Monitor Description

Note: Refer to Appendix A, “Loudness Measurement Guidelines and Techniques”

for more information about LKFS parameters and this function, as well as practical measurement techniques.

This function monitors selected output (“destination”) channels from the Audio Routing/Gain Control function and applies signal analysis based on ITU-R BS.1770-1 – ATSC A/85 criteria to produce an LKFS measurement and provide indications of under-threshold and over-threshold level conditions.

The function can monitor any combination of embedded, AES, or analog channels selected as the L, R, C, Ls, and Rs I TU-R BS.1770-1 channels (note that the LFE and AUX channels are not included in any LKFS calculations). Because the LKFS monitor uses output (post-processed “destination”) channels, LKFS values displayed are post-loudness processed values.

The functions pro vides a configura ble moving avera ge perio d for t ailorin g the measurement to suit various program material conditions.

Tone Generator Function

The 9085 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 a udio outputs.

18 discrete sine wave f requencies ar e available , ranging from 50 Hz to 1 6 kHz (default frequency is 1.0 kHz).

1-12 9085 PRODUCT MANUAL 9085-OM (V4.3)

Introduction 9085 Functional Description

AES Audio Input Advanced Features

AES Sample Rate Converter

The 9085 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 data such as

Dolby Dolby AES or embedded audio signal, SRC is automatically bypassed along with gain and polarity controls.

Zero-Delay Audio Embedding

In cases where additiona l delay must be avoided, it may be desirable to e mbed 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.

Digita l™ sign al ( in a ccord ance wit h SMPTE 337M ) is det ected on an

When zero-delay audio emb edding is en abled for a give n AES pair , th e pair is directly embedded int o its corres ponding group (for example , AES Pair 1 in to embedded channels 1 an d 2; AES Pai r 2 int o embedde d channe ls 3 an d 4, a nd so on) with the normal audio sync delay being bypassed.

This function overrides the audio routing system (for example, if AES Pair 1 is selected then the cont rols to route AES Pair 1 int o other embedded cha nnels 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)

If your 9085 is equipped with Dolby® decoding as an option, refer to supplement “Dolby Decoding Option (+DEC)” (PN DDO-MS) that was shipped with this manual.

9085 Rear I/O Modules

The 9085 physically inter faces to sys tem video and audi o connectio ns using a Rear I/O Module. Figure 1-8 shows a typical 9085 Rear I/O Module.

All inputs and outputs shown in the 9085 Functional Block Diagram (Figure 1-1) enter and exit the card via the card edge backplane connector. The Rear I/O Module breaks out the 9085 card edge connections to industry standard connections that interface with other components and systems in the signal chain.

In this manner, the inputs and outputs requ ired for a pa rtic ular appli cati on can be accommodated using a Rear I/O Module that best suits the requirements. The required input and outputs are broken out to the industry standard connectors on the Rear I/O Module; the unused inputs and outputs remain unterminated and not available for use.

The full assortment of 9085 Rear I/O Modules is shown and described in 9085 Rear I/O Modules (p. 2-6) in Chapter 2, “Installation and Setup”.

Phoenix terminal block connectors for 3-wire and 2-wire terminations

Viewed from rear, the right column of BNC connectors accommodates the right-most card, with the left column accommodating the adjacent card to the left.

In this example with two 9085 cards in slots 1 and 2, the right column serves 9085, slot 1 and the left column serves 9085, slot 2.

In this example, an RM-9085-G Rear I/O Module provides a connection interface for the signal types shown here.

BNC connectors for coaxial video and AES audio signals

Where a maximum of five BNC connections can suit particular I/O requirements, a “split” Rear I/O Module offers maximum card density within the frame by accommodating two cards using a module occupying no more area than a standard module. The RM-9085-A/S shown here accommodates the signal complement shown for two adjacent 9085 cards. (Split modules are identified by “/S” in the part number.)

Overview

Chapter 2

Chapter 2 Installation and Setup

This chapter contains the following information:

• Setting I/O Switches for AES I/O (1-4) Ports (p. 2-1)

• Installing the 9085 Into a Frame Slot (p. 2-2)

• Installing a Rear I/O Module (p. 2-4)

• Setting Up 9085 Network Remote Control (p. 2-1 1)

Setting I/O Switches for AES I/O (1-4) Ports

Note: This procedure is applicable only if any of the four AES I/O (1-4) ports on the

9085 are to be used as outputs (the switches are set to input mode by factory default). The 9085 is equipped with a four-section red DIP switch that sets AES pairs 1 thru 4 as either inputs or outputs. The factory default position is the input position for each pair.

• If all of the AES I/O (1-4) ports are to be used as inputs (or not used at all), omit this procedure.

• If any of the AES I/O (1-4) ports are to be used as outputs, set the switches as described in this procedure.

Note switch S11 thru S14 settings for AES I/O 1 thru AES I/O 4 mode shown in Figure 2-1. For p ort to be used as an output, set switch to down position as shown in Figure 2-1.

Note: Regardless of S11 thru S14 settings for AES I/O 1 thru AES I/O 4, outputs

AES OUT (1-4) are still available on cards equipped with a Rear I/O Module

having dedicated AES OUT BNC connecto rs.

Installation and Setup Installing the 9085 Into a Frame Slot

Note: If installing the 9085 in a slot with no rear I/O module, a Rear I/O Module is

required before cabling can be connected. Refer to Installing a Rear I/O Module (p. 2-4) for rear I/O module installation procedure.

CAUTION

Note: Check the packaging in which the 9085 was shipped for any extra items such

as a Rear I/O Module connection label. In some cases, this label is shipped with the card and should be installed on the Rear I/O connector bank corresponding to the slot location of the card.

Install the 9085 into a frame slot as follows:

1. Determine the slot in which the 9085 is to be installed.

2. Open the frame front access panel.

3. While holding the card by the card edges, align the card such that the

plastic ejector tab is on the bottom.

4. Align the card with the top and bottom guides of the slot in which the

card is being installed.

5. Gradually slide the card into the slot. When resistance is noticed, gently

continue pushing the card until its rear printed circuit edge terminals engage fully into the rear I/O module mating connector.

CAUTION

If card resists fully engaging in rear I/O module mating connector, check for alignment and proper insertion in slot tracks. Damage to card and/or rear I/O module may occur if improper card insertion is attempted.

Verify that the card is fully engaged in rear I/O module mating connector.

7. Close the frame front access panel.

8. Connect the input and output cables as follows:

• If the 9085 is being installed in a PN 8310-BNC or 8310-C-BNC

frame, refer to the label on the connector bank corresponding to the card’s slot location for connector designations.

• If the 9085 is being installed in a frame using a specific 9085 Rear

I/O Module, connect cabling in accordance with the appropriate diagram shown in Table 2-1, “9085 Rear I/O Modules” (p. 2-6).

9. Repeat steps 1 through 8 for other 9085 cards.

9085-OM (V4.3) 9085 PRODUCT MANUAL 2-3

2 Installing a Rear I/O Module

Note: The 9085 BNC inputs are internally 75-ohm terminated. It is not necessary to

terminate unused BNC inputs or outputs.

Note: External frame sync reference signals are received by the card over a refer-

ence bus on the card frame, and not on any card rear I/O module connectors. The frame has BNC connectors labeled REF 1 and REF 2 which receive the reference signal from an external source such as a house distribution.

Note: To remove a card, press down on the ejector tab to unseat the card from the

rear I/O module mating connector. Evenly draw the card from its slot.

10. If network rem ote control is to be used for the fram e and the frame has

not yet been set up for remote control, perform setup in accordance with

Cobalt 9000RCS-RM)”.

Note: If installing a card in a frame already equipped for, and connected to

DashBoard™, no network setup is required for the card. The card will be discovered by DashBo ard™ and be ready for use.
