Creating and Deleting a Unit

Creating and Deleting a Unit
A unit is a virtual VTR. It can play and record video and audio just like a VTR.
The UADD command, which you can use to create units, returns the name of the unit as
shown in the following example:
% UADD MFCODEC_0 * SHAR
202 OK
U1
U1, in this case, controls the MFCODEC_0 video board, which includes both an input
video port and an output video port.
Deleting a Unit
Units can be deleted using the following command:
UCLS unit-name
Multiple Connections to a Unit
Once a unit has been created, it can be controlled by a number of MVCP connections by
opening it:
UOPN unit-name
When multiple MVCP connections are made to one unit, the unit is not deleted until all
of the connections have deleted it.
Caution: Opening a unit owned by a Sony or VDCP port using MVCP commands (for
example, UOPN) causes unpredictable behavior.
