Automation Control

Automation commands can be used to change internal metadata source values. The internal
sources of metadata are termed “banks.” There are 4 available banks.

Note: For details of the Oxtel automation protocol, see the Automation publications listed
under

Applicable Publications and Tools

on page 3.

Internal Metadata Sources

Oxtel automation commands starting with “o” are used for controlling internal Dolby metadata
parameters.

Note: Although many aspects of metadata sources can be controlled individually, it is pref-
erable to prepare a set of required presets beforehand and load them using the ‘oT’
command.

Up-Mix

“Up-mix” is the conversion of 2-channel audio to multi-channel audio. The up-mix audio option
adds integral up-mix capability to the Imagestore 750. It creates a multi-channel-compatible
audio signal from a stereo source using the Linear Acoustic upMAX

TM

up-mixing algorithm.

The up-mix audio module provides the following features:

Stereo to multi-channel audio.

Up to 4 up-mix modules.

Linear Acoustic’s upMAX

TM

up-mix algorithm.

AutoMAX

TM

and metadata follow modes.

Down-mix compatible output.

Control through Oxtel automation command extensions.

Configurable in the ‘Audio Graph’ page of the Imagestore 750 Configurator. (See Chapter 8.)

Note: up to 4 Dolby encode, Dolby decode, and Up-Mix audio modules can be installed in
the Imagestore 750 at one time.
