Step 1 - Define Virtual Inputs and Sources

First, define your Virtual Input type.



Eight Virtual Inputs are available (Audio Configuration > Virtual In 1-8).



Virtual Inputs 1-4 can be configured as Mono, Stereo, Surround 5.1, or Surround 5.1+2.0.



Virtual Inputs 1 and 2 can be configured as Dolby E, Dolby Digital, or Dolby E/Digital with DownMix

(auto decoder).

© 2014 Imagine Communications. Proprietary and Confidential. Edition C | Page 7

APM6803+

Application Examples



Virtual Inputs 5-8 can be configured to either Stereo or Mono.



Virtual Inputs 5-8 are disabled by default, and can be turned on as required.

Configuring the APM6803+

Next, define your source based on the selected Virtual Input type.



For example, if the Virtual Input type is Stereo, define the source for Stereo L and R channels.



You can optionally apply Phase Invert, Gain, or Delay settings to a virtual stream by going to the relevant section under the Virtual Input stream.

Step 2 - Define Surround Processing

Once defined, virtual input streams are smart routed to surround processors so you can process the audio stream using DTS® Neural UpMix, DownMix, or MultiMerge.



Go to Surround Processing (Audio Configuration > Surround Processing) and select the type of processing to apply to your virtual input stream along with the source definition.



For example, if you select MultiMerge as the processing type, define the source for your Surround In and Aux In.



Go to the relevant processing section under Surround Processing (UpMix Settings, DownMix

Settings, etc.) to define detailed settings for your selected function.

Step 3 - Define Virtual Outputs and Sources

Next, define your outputs and sources.



Four Virtual Outputs are available for you to define your output configuration

(Output Configuration > Virtual Out 1-4).

 Virtual Outputs 1-4 can be configured as Mono, Stereo, or Surround.

 Virtual Outputs 1 and 2 can be configured as Dolby E or Dolby Digital.

Step 4 - Turn on Loudness Control

Loudness Control can be enabled or disabled at the stream level when defining your Virtual output.



Select Enable against Loudness Control for a virtual stream

(Output Configuration > Virtual Out > Audio Loudness Control Enable).



Define detailed loudness control settings by selecting Loudness Control under any of the Virtual outputs. You can define warning/alarm thresholds, target loudness, and other related settings.

Application Examples

Step 5 - Define Output Routing

Configuring the APM6803+

Finally, define the routing for your Virtual outputs. For example, you may want to embed a PCM 5.1+2.0 stream into SDI video. Or you may want to route two separate 5.1 and 2.0 streams to AES.

Go to Audio Configuration > Output Router > Embedded or AES > Audio Source Select to define the routing.

Note: You can also handle incoming audio metadata by identifying its source (Serial Port, VANC, Dolby stream). Once identified, status monitors are available to view the incoming metadata. A Generator is also provided to optionally generate your own metadata, which can then be output as required (for example, to correct situations that arise because of incorrect/missing dialnorm, or incorrect loudness).

The Generator can also be used to create fallback metadata in case any incoming metadata was lost.

Application Examples

EAS

EAS

Note: The purpose of this tutorial is to take you through the steps to enable EAS in your audio workflow.

It does not go into the details of defining virtual inputs, outputs, and output routing as the other tutorials do.

EAS is an Emergency Alert System used in North America to send emergency information via a single AES stream (stereo) that replaces the audio. EAS control is a high priority control feature that has the ability to replace any audio stream with an EAS source when:



Virtual In 8 has EAS Source Enable enabled



Virtual Out x has Out x Allow EAS Source Override enabled.

Note: Note that activation of this EAS control feature does not make the APM6803+ generate an EAS protocol compliant signal (EAS Encoder) nor detect a valid EAS Input signal per FCC Part 11 (EAS). You have to manually select the EAS source signal for activation, routing, and embedding.

Configuration Steps

STEP 1 - Define Virtual Inputs and Sources (on page 31)

STEP 2 - Enable EAS - Define Virtual Input 8 (on page 31)

STEP 3 - Enable EAS in Output - Define Virtual Outputs (on page 32)

STEP 4 - Define Output Routing_ (see "STEP 4 - Define Output Routing" on page 32)

STEP 1 - Define Virtual Inputs and Sources

Per your workflow, define your virtual inputs and the source of those inputs. Refer to previous tutorials for examples of how to do this.

STEP 2 - Enable EAS - Define Virtual Input 8

1. Go to Parameters > Audio Configuration > Input Configuration > Virtual In 8

• Set Virtual In 8 Enable to Enabled

• Set Virtual In 8 Type to Stereo

• Set EAS Source Enable to Enabled

Note: Gain, Delay, and Phase Invert set for Virtual In 8 will also be effective on the EAS audio stream.

Note: EAS can also be enabled through GPI configuration, but only one of them is active at a time.

APM6803+

Application Examples

STEP 3 - Enable EAS in Output - Define Virtual Outputs

Define your virtual outputs based on your workflow. Set at least one of the outputs to allow EAS.

1. Go to Parameters > Audio Configuration > Output Configuration > Virtual Out x

• Set Virtual Out x Enable to Enabled

• Set Virtual Out x Type to <Type>

2. Go to Parameters > Audio Configuration > Output Configuration > Virtual Out x > Source Select

• Set Out x Allow EAS Source Override to Yes

Note: Loudness Control, Gain, and Phase Invert for Virtual Out are also effective when EAS is enabled.

EAS

STEP 4 - Define Output Routing

Define your output routing. In the Output routing, the following conditions affect EAS:



If an audio tone or mute is selected as the source of embedded or AES audio, it is not replaced by

EAS.



If Dolby is passed out, its content is not replaced by EAS.

Troubleshooting

The following is a quick reference for errors you may encounter and how to handle them.

Troubleshooting

Table 1: Troubleshooting

Error Message

Failed - No License

Failed - Router Full

Failed - DSP Full

Meaning

This error relates to DTS Neural licensing and indicates that you are attempting more processing than your current licensing supports.

Availability of UpMix, DownMix,

MultiMerge, and Loudness

Control is directly controlled by the available DTS Neural licensing.

Workaround

Review available licenses versus current utilization by going to General > Licensing and General > Utilization.

If you have run out of DTS licenses, you have 2 options:

1. You can have a maximum of 16 DTS licenses, so if you have not reached the limit, you can buy additional licenses to support your configuration requirements.

2. DTS credits are flexible, so you can temporarily free up some credits, do the required processing and then switch back as required.

Release one of the audio functions and free up an AAP block. Then attempt additional audio processing.

All 4 AAP blocks are currently utilized.

If you go to Audio Configuration in the parameter interface, the allocation of audio functions across the AAP blocks is displayed and you will see the current allocation.

The DSP does not have enough resources. Refer the resource utilization percentage displayed under Audio Configuration.

Or refer to the APM6803+User

Manual for resource utilization for each function block.

Release one or more of the AAP function blocks.
