Viz Engine Administrator’s Guide

• Channel Geometry: Sets the channel geometry. Available options are: Mono ,

Stereo , Anamorphic widescreen , 7.1 and Quad .

• Used Channels: Sets the number of configurable channel alias fields that can be

mixed by the internal channels in Viz Engine (software). On a Matrox system this

number must be equal to the number of configured input channels (hardware). This

setting is independent of the Channel Geometry setting.

• Reset Aliases: Sets the channel aliases to the default option; however, the custom

entry is not removed.

• Out Channel 0-15: The Out Channels represent the internal Viz audio channels,

which are mixed to the output device one by one. Alias names are not only useful

for creating multilingual systems, but also define the channel geometry for the

Default and FX audio clip mix modes. Aliases are separated by a semicolon. The

Audio plugin only uses the channel aliases to find the correct speakers for Pan and

3D sound effects in FX mode. With this functionality you are able to use any of the

16 internal audio channels to play any audio geometry.

Audio Settings Setup tab

In this section all installed DirectSound audio cards are listed displaying the available

audio inputs that can be mixed to one audio output by Viz Engine. It is currently only

possible To manually activate an audio device by editing the configuration file.

Note: The Matrox audio-extension board is not configurable through this user

interface.

• Sample Rate: Reserved for later use. Displays the sample rate. Default sample

rate is 48kHz (48000) which is the maximum allowed.

• Device n : Displays the name of the audio card.

• Bits per Sample: Reserved for later use. Displays the number of bits used per

sample. Default value is 16 Bit per sample rate.

• Mode: Refers to the audio mode of the Matrox board. Available modes are

Embedded, AES, Embedded AES, Loop and Default.

• Embedded: Forces the Matrox board to capture audio from the video signal and

outputting embedded audio.

• AES: Forces the Matrox board to capture and output audio through the AES / EBU

connectors.

• Embedded AES: Forces the Matrox board to capture audio from the video signal

and outputting it to the AES / EBU connectors.

• AES Embedded: Forces the Matrox board to capture audio from the AES

connectors and outputting the audio as streams in the video signal.

• Loop: Moves the audio from the inputs to the outputs without being down-mixed

by Viz Engine.

• Default: The default device(s) are used (usually the built-in sound board).
