4X.C4 : DEFINE EVENT
This command is used to define the TIMELINE even for a DEVICE.
An event executes the command (DATA-6 ~) in accordance with the specified conditions
(DATA-1 to DATA-5), and is deleted. If the event is not executed correctly, the bits corre-
sponding to the ABORT bit (DATA No. 9, bit-7) of STATUS and to the “7X.C8 : UNSUC-
CESSFUL EVENT” command, are set.
Processing such as edit delay, etc. during editing is performed in the device side. The event is
not executed when the TIMELINE is not running, or while CUE UP is executing.
A number is attached to events in the order of transmission (receive) of the “4X.C4 : DEFINE
EVENT” command. Both the controller and device control the event numbers with a 1:1
correspondence. The number is consecutively given in the range from 0001h to FFFFh totaling
65535 values. The number increments unless All Clear (DATA-1, 2 = 00h) is performed by the
“42.C5 : CLEAR EVENT” command. When the event number exceeds FFFFh, it returns to
0000h. Its contents are ignored even though the “4X.C4 : DEFINE EVENT” command is
executed. The event number remains at 0000h. However, the already defined events are
executed correctly.
When the remaining capacity of the event buffer in which events are stored becomes 0000h, the
contents are ignored when the “4X.C4 : DEFINE EVENT” command is executed and the event
numbers are not updated.
DSR series VTR has the capacity of 7 events as a buffer.
When the selected tape time is specified as the trigger source, the events are executed in the
order of event numbers. On the contrary, when the timeline is specified as the trigger source, the
events are sorted in the order of trigger time, and executed.
[DATA-1]
bit-7
Event processing after execution is specified.
0 : Event is deleted after execution.
1 : Event is stored without deletion after execution so that it can be re-executed.
Re-execution is initiated when the timeline has passed 24 hours or when the timeline
agrees with the trigger time as the timeline is re-started, etc. Deletion of the event is
performed by the “42.C5 : CLEAR EVENT” command.
bit-6
This specifies the source (trigger source) which generates the trigger timing to execute an
event.
0 : Timeline is selected.
1 : Selected tape time is selected.
[DATA-2 to DATA-5]
The timing (trigger time) which triggers execution of an event is specified by the time data.
For the data format, refer to “24.31 : CUE UP WITH DATA”.
[DATA-6 ~]
This specifies the command to be executed. The commands which can be specified are the
“0X.XX”, “2X.XX”, “4X.XX” and “8X.XX” commands except “00.11” and “0X.FX”.
Example) When executing the PLAY command at 0 hour.
