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.

E or Dolby® Digital™ audio streams. When a valid Dolby® E or

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.

Control and Display Descriptions

This secti on describes the user interface controls, indicators, and displays for using the 9085 card. The 9085 function s can be acces sed and contr olle d using any of the user interfaces described here.

The format in which the 9085 functional controls, indicators, and displays appear and are used varies depending on the user interface being used. Regardless of the user interface being used, access to the 9085 functions (and the controls, ind icato rs, an d disp lays r elat ed to a particul ar f uncti on) fo llows a general arrangement of Function Submenus under which related controls can be accessed (as described in Function Submenu/Parameter Submenu Overview below).

Note: DashBoard™ and the Remote Control Panel provide greatly simplified user

interfaces as compared to using the card edge controls. For this reason, it is strongly recommended that DashBoard™ or a Remote Control Panel be used for all card applications other than the most basic cases. Card edge control codes are not included in this manual. If card-edge control is to be used, obtain a copy of “Manual Supplement – Card-Edge Control Reference Master List and Instructions for Using Compass Codes” (989CEC-MS.pdf) at www.cobaltdigital.com>Support>Documents>Reference Guides.

Note: When a setting is changed, settings displayed on DashBoard™ (or a Remote

Control Panel) are the settings as effected by the 9085 card itself and reported back to the remote control; the value displayed at any time is the actual value as set on the card.

Function Submenu/Parameter Submenu Overview

The functions and related pa rameters avai lable on the 9085 car d are organ ized into function submenus, which consist of parameter groups as shown below.

Figure 3-1 shows how the 9085 card an d its submenus ar e orga nized, and also provides an overview of how navig ation is performed be tween cards, func tion submenus, and parameters.

If using DashBoard™ or a Remote Control Panel, the desired 9085 card is first selected.

Cobalt® Remote Control Panel User Interfaces

(See Figure 3-3.) Similar to the function submenu tabs using DashBoard™, the OGCP-9000 (and OGCP-9000/CC) Remote Control Panels have a Select Submenu key that is used to display a list of function submenus. From this list, a control knob on the Control Panel is used to select a function from the list of displayed function submenu items.

When the desired function submenu is selected, each parametric control or selection list item associated with the function is displayed. Scalar (numeric) parametric values can then be adjusted as desired using the control knobs, which act like a potentiometer. Items in a list can then be selected using the control knobs which cor respo ndingl y act li ke a r otary switch . (In t his man ner, the setting effected using co ntr ols and selection lists displayed on t h e Co ntr ol Panel are comparable to t he submenu i tems acce ssed and committed u sing the 9085 card edge controls.)

Figure 3-3 shows accessing a function submenu and its parameters (in this example, “Embedded Audio Output Group 1/2”) using the Control Panel as compared to using the card edge controls.

Embedded Audio Group 1/2 function (among others) is accessed using the Control Panel Select Submenu key. Embedded Audio Group 1/2 function is selected from the list of functions (submenu items) using any knob

When the Embedded Audio Group 1/2 function submenu is selected, its related parameters are now displayed.

In this example, Gain for Embedded Channel 1 is adjusted using the corresponding Gain control knob.

Note: In this mode AES rate must match the input video rate or

audio dropouts will occur.

Note: AES audio must be nominally 48 kHz.

• Enabled: In this mode, AES SRC for the corresponding AES input pair is enabled. SRC enabled allows the 9085 to interface with asynchronous AES sources (sources in which the AES timing does not match the video reference timing). SRC can be used to compensate for minor clock rate differences in the AES stream and the input video stream.

disables or enables Passthrough as follows:

• Off: Disables AES passthrough for the selected AES input pair. Passthrough is set to Off by default.

• On: Passthrough is turned on, with the corresponding AES output pair to act as a bit-for-bit copy with zero delay of the corresponding AES input pair.

Note: • AES Passthrough set to On overrides normal audio

routing. Gain and polarity control is not available when AES passthrough is enabled.

• AES audio must be synchronous with video to use this feature.

(1 thru 8) disables or enables Zero-Delay Embedding as follows:

• Off: Disables Zero-Delay Embedding for the selected AES input pair. Zero-delay embedding is set to Off by default.

• On: The selected pair directly embeds into its corresponding group (AES Pair 1 embeds into embedded channels 1 and 2; AES pair 2 embeds into embedded channels 3 and 4, and so on) with the normal audio sync delay being bypassed.

Note: • Zero Delay Embedding overrides the standard audio routing

system. For example, if AES Pair 1 is selected, then the controls to route into embedded channels 1 and 2 will not apply. Gain and polarity control is not available when zero-delay embedding is enabled.

• AES audio must be synchronous with video to use this feature.

• The card does not check for conflicts on a given line number. Make certain the selected line is available and carrying no other data.

Provides Audio/Video Re-sync function.

Audio/Video Resync (Framesync tab )

Note: Although labeled as “Framesync”, the 9085 framesync function is mainly intended to provide audio/video resyncing

(loudness processing induces an 8 msec delay which can be nulled by advancing the audio 8 msec using the Audio Offset from Video control described below). When loudness processing is enabled, the glitch-free audio resyncing provided by the framesync audio SRC is not available. To ensure glitch-free audio resyncing, it is recommended that the incoming video be locked to reference upstream of this card, and to have the framesync on this card set to the corresponding external reference (Reference 1 or Reference 2).

In this manner, the audio SRC is never called upon by the 9085 card processing, while also allowing the 9085 to benefi t in providing full Freeze to Last Frame or Freeze to Color protection upon loss of input. If this protection is required without the incoming video being upstream frame synced and with framesync enable set to an external reference on this card, hard audio resets (and the resulting audio “hits”) must be expected.

• Framesync Enable Disables the Frame Sync function, or selects from choices below.

• Off: Disables Frame Sync function; output video timing matches the input video timing.

• Reference 1: Allows Frame Sync function to use external Reference 1 as the reference standard.

• Reference 2: Allows Frame Sync function to use external Reference 2 as the reference standard.

Note: If Reference 1 or Reference 2 is selected and an

appropriate external reference is not received, the status portion of DashBoard™, indicating invalid frame sync

reference error. (Additionally, the card edge ERR indicator illuminates indicating the same.) External reference signals Reference 1 and Reference 2 are distributed to the card and other cards via a frame bus.

• Input Video: Uses the input video signal as the

reference standard.

Note: If Input Video is used for framesync, any timing instability

on the input video will result in corresponding instability on the output video.

horizontal delay between the output video and the frame sync reference. (Range is -64.000 thru 64.000 µsec)

Note: When an external framesync reference is used, the card will not

produce a framesync reset until the variance between framesync reference and output video exceeds ± 2 clock periods. Therefore, a framesync reset will not result if offsets within this window are applied.

To apply an offset/framesync reset within this window, first apply a relatively large offset, then apply the target smaller offset.

Example: T o apply a 1-period offset, first apply a 10-period positive offset and then apply a 9-period negative offset. This results in the target 1-period offset being applied to the output video.

Note: Audio SRC is disabled when Framesync is enabled in Input Video

mode. Audio SRC is always off when loudness processing is

enabled.

When Framesync is enabled, specifies the smallest amount of latency allowed by the frame sync (latency measurement in output video frames). The frame sync will not output a frame unless the specified number of frames are captured in the buffer. The operational latency of the frame

sync is always between the specified minimum latency and minimum latency plus one frame (not one field).

(Maximum range is 0 to 32.) Note: Due to card memory limits, the maximum available Minimum

Latency Frames is related to the output video format selected. For example, with a 525i59.94 output, the practical maximum limit is 13.

When using this control, be sure to check the Framesync Status display as follows:

• Latency frames selection within limits.

• Latency frames selection exceeds limits.

• Audio Hard Resync Threshold Control Sets threshold at which hard resync is applied if audio-video offset

With offset less than selected hard resync threshold, resync is progressively applied in many small steps to provide a seamless, glitch-free retiming. After the successive steps, the audio is synchronized with the video (in this example, 40 msec). (Progressive correction is applied at 1 msec/sec appr. rate.)

(Range is 1.5 to 13.0 frames in 0.1 frame increments) Note: Glitch-free operation described here is available only with loudness

processing disabled and with card set to use an external reference.

In this example, initial offset of 200 msec (appr. 6 frames) is below 9 frame threshold and results in soft resync being progressively applied.

Audio LTC and RS-485 LTC controls described below only appear on cards with +LTC licensed optional

feature. This feature allows bidirectional conversion between VBI-based timecode and LTC timecode on audio and RS-485 interfaces.

• Timecode Source Status Displays Displays the current status and contents of the supported timecode formats shown to the left.

• If a format is receiving timecode data, the current content (timecode running count and line number) is displayed.

• If a format is not receiving timecode data, Unlocked is displayed.

• If Audio LTC is being received, the timecode running count is

displayed.

• Audio LTC Source selects audio source to be used by card audio LTC function as listed below.

• Emb Ch 1 thru Ch 16

• AES Ch 1 thru Ch 16

• Analog audio Ch 1 thru Ch 8

Note: Audio LTC Source must be appropriately set for card to

receive and process audio LTC.

• Incoming ATC Packet Removal Control Enables or disables removal of existing input video ATC timecode packet s from the output. This allows removal of undesired existing timecodes from the output, resulting in a “clean slate” where only desired timecodes are then re-inserted into the output. (For example, if both SDI ATC_VITC and ATC_LTC are present on the input video, and only ATC_LTC is desired, using the Removal control will remove both timecodes from the output. The ATC_LTC timecode by itself can then be re-inserted on the output using the other controls discussed here.)

• Source Priority As described here, provides 4-level prioritization of timecode format choices from choices shown to the left.

Source Priority 1 thru Source Priority 4 select the preferred format to be used in descending order (i.e., Source Priority 2 selects the second-most preferred format, and so on. See example below.)

• Processing Profile Preset Selection

Turns loudness processing on and off, and allows selection of preset loudness profile best suited for the program material and/or model of processing desired as follows:

• TV 5B General – This is the general, recommended preset for all types

of content. It provides moderate dynamic range compression and is calibrated to produce audio having an average dialog loudness of

-27 LKFS with no additional output level trim. Use of this preset as an initial setting is recommended.

• TV 5B Light – Similar to TV 5B General, this preset varies in that

multi-band compression is reduced closer to 2:1, thereby providing a more gentle action.

Note: This preset sacrifices agility in loudness control in favor of a more

gentle compression profile; this preset may not be suitable for some material.

• TV 5B Heavy – Similar to TV 5B General, this preset varies in that

multi-band compression is increased for greater level density/adherence to target at the expense of dynamic range.

• TV 5B Loud – Similar to TV 5B Heavy, but with a louder, more punchy

perception.

• ITU Loud Limit – Utilizes a specially tuned input AGC plus multi-band

and a final limiter to gradually adjust the average program loudness to an internally set AGC value, with the multi-band and final limiters acting until the AGC gains control of the level. This preset is most appropriate for ingest or live program material.

Note: This preset bypasses the multi-band AGC. As such, it has less

ability to manage spectral balance.

• Protection Limit – Bypasses all processing except for final output

limiter, which is set only to prevent overload.

Note: Unless the audio received has already been loudness processed,

this setting is typically not recommended.

• Master Output Gain Control Allows fine adjustment of the overall output gain. (-20.0 dB to 11 dB range in 0.1 dB steps; default = 0.0 dB)

Note: This control is primarily useful in matching the output level to the

desired LKFS target if required. Also, it is useful (where desired) in matching various Processing Profile presets to have similar output levels. In this manner, a custom master output level can be applied to a Processing Profile preset, and then the Processing Profile preset, the custom master output level setting (and any other card settings) can be saved and re-applied using a general card saved preset (as described in Presets (p. 3-40).

Note: (USA) ATSC A/85 and the CALM Act (H.R. 1084/S. 2847) requires that when real-time loudness processing is

applied using a fixed target loudness of -24 LKFS, downstream AC-3 encoding must correspondingly use a fixed dialnorm value of -24. The default target loudness (as set by the loudness processor Master Output Gain Control) is -24 LKFS. When loudness processing is engaged, make certain AC-3 dialnorm is set as described here.

Check status indicators and displays

• On both the frame Network Controller Card and the 9085, in all cases when power is being properly supplied there is always at least one indicator illuminated. Any card showing no illuminated indicators should be cause for concern.

• Check the Power Consumed indications for both the +12 V and -7.5 V supply rails for the 9085 card. This can be observed using the DashBoard™ Card Info pane, or using the card edge controls and indicators as shown in Figure 3-4 on page 3-7.

• If either of the rail supplies show no power being consumed, either the frame power supply, connections, or the 9085 card itself is defective.

• If either of the rail supplies show excessive power being consumed (see Technical Specifications (p. 1-18) in Chapter 1, “Introduction”), the 9085 card may be defective.

Make certain all cable connections are fully secure (including coaxial cable attachment to cable ferrules on BNC connectors). Also, make certain all connecting points are as intended. Make certain the selected connecting points correlate to the intended card inputs and/or outputs. Cabling mistakes are especially easy to make when working with large I/O modules.

Appendix A

Chapter 1 Loudness Measurement

Guidelines and Techniques

This appendix provi des a conde nsed guide to pract ical t echniques for prope rly measuring and assessing loudness in various types of program material.

The content here is in general accordance with ATSC A/85, “ATSC Recommended Practice: Techniques for Establishing and Maintaining Audio Loudness for Digital Television”. This document is available free of charge and can be downloaded by going to:

http://www.atsc.org/standards/practices.php

About Loudness Measurement App lied to Program Material

A very useful aspect of th e loudness measurement model i s t hat a t arget and a measured end-assessment are based upon simple, single-value LKFS measurements that can be unambiguously displayed and assessed. When properly performed as described in this appendix, the LKFS measurement model accommodates reas onable short -ter m loudne ss varia tions i n most t ypes of professionally produced material without nuisance failure indications or ambiguous results.

The loudness measurement model specified in ATSC A/85 uses the LKFS loudness unit to provide the simple, single-unit value that can be used to assess program material loudness. Basically, before an assessment is performed, two important initial facets must be considered:

• Target LKFS Value – This is the desired re ading that is to be

observed for a given segment or piece of program material.

• Measurement Technique – Consideration should be given in using

techniques that result in the most meaningful or representative LKFS measurements. These techniques are described below, along with techniques suggestions suitable for various types of pr ogr am mat er ia l.

9085-O M (V4.3) 9085 PRODUCT MANUAL A-1

Appendix A About Target LKFS Value

About Target LKFS Value

(See Figure A-1.) Adherence to a target LKFS value across various program material (typically from any number of individual, diverse sources) relieves viewers from having to constantly adjust program volume at their homes in order to maintain an overall comfortable, desired loudness level. General guidelines for determining a target LKFS value are as follows:

• Unless specified by a metadata dialnorm value or some other

specified guidance, tar get LKFS should be at or about -27 ± 2.0 LKFS (that of the typical dialnorm value) across any portion of program material containing any appreciable audio content (anything other than dramatically or aesthetically intentional silence).

• Because the LKFS unit of measure is directly derived from the

decibel, a gain change of a given amount modifies measured LKFS by the same amount. For example, material exhibiting an LKFS of

-12 LKFS can be made to match that of material exhibiting a

-24 LKFS level by reducing the overall level at the source by 12 dB.

• Where local content is to be added to a network-supplied feed (e.g.,

local commercial or programming announcements), care should be taken that the LKFS level of local content matches that specified by the metadata dialnorm.

• Dynamic Range Control (DRC) control/management systems by

themselves cannot unconditionally be relied upon to assure proper LKFS compliance. Many DRC systems use measurement/control schemes that do not reflec t perc eived l oudness . A system spe cifi ed to use energy measurement/assessment models reflecting perceived loudness, such as the Cobalt

loudness processing used by this card (AEROMAX™ licensed from Linear Acoustic™), can reliably provide DRC to achieve LKFS compliance.

Figure A-1 shows an example of measuring LKFS for an ingest piece and using the result to as sess an d remedy the l oudness var iation be tween the pi ece and a dialnorm-specified network feed.

Measurement Techniques For Various Program Material Forms

Because of the sometimes intentional broad variance of overall levels and audio density in various types of program material, consideration must be given in applying techniques that concentrate only on meaningful segments within a piece where representative LKFS measurements can be obtained. Currently, a fully automated means of accurate ly assess ing LKFS f or all ca ses or forms of material has not been specified in ATSC A/85. Therefore, techniques appropr iate for t he materia l must be applied. Th is sectio n provid es guidance and examples of properly applied techniques for various cases and forms of typical program material.

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

Appendix A Measurement Techniques For Various Program Material Forms

Importance of an Anchor Element

ATSC A/85 defines an anchor element as the aural element in material that serves as the item within a group of sounds that assumes a dominant role and is the “center of attent ion”. For example, in a piece containing relatively constant dialog (such as a typical commercial), the mix and creative input would typically position this dialog as the predominate or “anchor” element in the mix (in terms of both relative level and channel placement). As such, all other elements would normally have levels that proportionally track and stay well below that of the anchor element. For example, in program material consisting of dialog and background sounds or music, the anchor element would be dialog with other sounds substantially lower in level.

Note that in a given piece, the anchor element can change assignment within the course of the material (for exa mple, at the end of a comm ercial where score music or a jingle now may assume the role of creative dominance and correspondingly become the anchor element).

Assumptions and Conditions For Meaningful LKFS Measurements

Again depending on the material form, meaningful LKFS measurement and assessment can be very straightforward or, conversely, require some techniques to help ensure a meaningful assessment is obtained. Very straightforward assessments can be obtained when the following are present and/or observed:

• T ypical pr oduction ae sthetics wi th typical post-produ ction refi nement

using moderate, controlled compression and aural content density.

• Consistent audio levels in center channel throughout the piece (e.g.,

dialog or music score).

• Dialog (or equivalent) serving as an anchor element.

• Material containing no excessive periods of unusual loudness or

silence.

• LKFS is intended as a long-term measurement. The shorter the

averaging period, the less representative an assessment is of a given pice of ingest mate rial . Where fe asibl e, an obser vation should run the entire length of the inge st material. If the materi al does not contain an anchor element, the predominate element (e.g., featured music or obvious effects) should serve as the anchor.

In these cases, the Aud io LKFS Monit or f unction can be used with it s de fault settings.

Figure A-2 shows an example (using a target LKFS of -24.0) where these assumptions can be followed, and an example where certain techniques should be applied in order to obtain a meaningful LKFS assessment.

Appendix A Measurement Techniques For Various Program Material Forms

60-second Commercial wit h Dialog and Background Music. In this example, predominate dialog in the center channel serves as an anchor element. Because of the relatively compressed and dense audio content, a simple observation over the course of the material can reliably be used to apply gain adjustment that correspondingly provides loudness correction.

Relatively high density and compression results in fairly consistent short-term LKFS, leading to an LKFS measurement that is highly representative of the entire piece.

5-minute Nature Show Act with Narrative/Background Music and Creative-Element Near Silence. In this example, predominate narrative dialog in

the center channel serves as an anchor element, with subordinate elements being music score and ambient soundtrack. However, the piece also contains a significantly long segment containing only very low-level ambient soundtrack during a nature close-up sequence. This loudness change is creatively intentional and must be maintained. If this segment is included in the LKFS observation, it can result in an under-representation of overall perceived loudness. If the gain is increased to compensate for this under-represented LKFS, loudness during periods of narrative/music will be unacceptably high. As such, proper technique would be to ignore the quiet portion.

Intentionally quiet segment, if included in measurement with

no consideration of technique, leads to an LKFS measurement that is under-representative of the entire piece.

Specific Measurement Techniques for Various Material Forms

Described below are specific techniques and suggestions for various settings and program material which can be assessed using the Audio LKFS Monitor function.

Live Production. The Audio LKFS Monitor function can be used in live

production to guide the mixing operator to maintain audio level at an LKFS reasonably close to that specified by the dialnorm. Where aural activity is significant (i.e., some sort of anchor element clearly exists), the LKFS measurement provides a good baseline of target loudness compliance. Observing LKFS over a 10-second period (appr.) will typically suffice.

Note that in this sett ing, audio may not be always be c ompressed/li mited; very wide swings in dynamic range are possible. Again, only segments that are realistically viable in terms of content density, anchor element, and level amplitude/consistency should be considered for measurement. If repeated or sustained “hot” level on the channel or overall mix.

Post-Production. The guidelines for this settings are similar to that used for

live production, except that a LKFS measurement should be observed for representative segments by cueing and rolling tape, thereby circumventing quiet segments from influencing the measurement.

LKFS “high” violations are noted, it may be indicative of an overall

Long-Form Finished Material. LKFS observation should be run for as long

a segment as possible, however restricting the observation to representative portion(s) within an act. A representat ive segment shoul d of course contai n an anchor element or the next reasonable equivalent. Only absent a representative anchor element should the unrestricted length of the piece be observed and considered.

Short-Form Finished Material (e.g., “Commercials”). Typically, this

material will have a clearly discernible anchor element and relatively consistent loudness density. As long as the material does not have loudness pauses exceeding half the overall run time (which is typically unlikely), a simple observation over the course of the material will typically provide a very reliable LKFS measurement.

A-6 9085 PRODUCT MANUAL 9085-OM (V4.3)

Appendix A Measurement Techniques For Various Program Material Forms

Modifying LKFS Assessments Using Parametric Settings

Measurement Window Setting. (See Figure A -3.) The Measurement

Window parameter sets the sampling time accumulated in each averaging recalculation. As such, longer periods will include more short-term LKFS “look-back” values into the moving average. Because the Measurement Window setting affects averaging that is used in measuring and calculating the LKFS measurement, changes in this setting will affect LKFS measurement.

Program Material short-term LKFS Shorter Measurement Window produces more

responsive averaged LKFS reading, with greater range variation over the course of sampling.

LKFS

Longer Measurement Window produces a more representative averaged LKFS reading over the course of sampling, with reduced sensitivity to short-term LKFS deviations.

Figure A-3 Modifying the Measurement Window Parameter

Long-Form Simplified Measurement. (See Figure A-4.) Post-production

long-form material can in many instances be easily assessed by applying a rather long

Measurement Window (in this example, 10 seconds). In this

manner, the typically brief loudness variations in professionally produced material (or breaks between material) will not result in nuisance errors. However, if the material exhibits a consistent gross deviation from the selected target LKFS or dialnorm (for example, due to level imbalance between a network feed and local insertion), the averaging period is conversely likely to be sufficiently short as to show a level-triggered error somewhere over the course of the offending material.
