7: Configuring and Using External Devices

4. Edit the control defaults ﬁle for each Sony control port as needed.

The directory /usr/vtr/config/system_defaults contains ﬁles specifying

the default control settings for system-wide resources, including the control

processors managing any Sony protocol control ports.

• Put control settings that apply to all Sony control ports in vtr.

• Put control settings that are limited to speciﬁc control ports in vtr_port, where

port is the server serial port number to which the controlling device is attached;

for example, vtr_1, vtr_2, and so on.

The following controls are supported by the Sony control module:

• vtr.control.device_type_id

• vtr.control.output.idle_mode

• vtr.control.timecode.mode

• vtr.control.clip.name

• vtr.control.superimpose.enabled

• vtr.control.edit.delay

• vtr.control.ee.delay

• vtr.control.ee.mode

• vtr.control.ee.record_select

• vtr.edit.preroll

• vtr.edit.postroll

See the vst-controls(5) man page for more information concerning the use and

default values of these controls.

An application can change these controls dynamically with the MVCP SSET

command; they can also be queried using the MVCP SGET command. For example:

SSET vtr_1 vtr.control.clip.name new-clip

This example creates the clip new-clip, if it does not already exist, and loads it onto

the units controlled by the device attached to serial port 1.

Note: The setting for vtr.control.output.idle_mode overrides the setting for

vtr.media.output.idle_mode of the underlying device.
