Description
The STOP command will return the selected port to the IDLE state.
The STOP command can be issued to a port in any state. When in IDLE, the
port will output black. Any material that is playing out, CUED or cueing is
aborted. No action will result if the STOP command is received when no
material is PLAYing. If the port was in the RECORD state, then the system will
stop recording at the next REF interval. A partial recording will have occurred
and the internal database for the length of the material will be updated to reflect
this reduced length. The part of the material received is kept stored on the disk
and is available for play.
The PLAY command causes the specified ID to play out.
The STILL command causes the currently playing ID to pause. The last frame
played prior to receiving the STILL command will continue being displayed.
The output port must be in the PLAY, or in the CUED state.
The CONTINUE command causes the ID currently in the STILL state to
continue playing. The output port must be in a PLAY, CUED, or STILL state or
an error will be logged.
The CLOSE command is used to break communication to a Signal (audio/
video) Port connection established by a preceding OPEN command. PORT is a
number representing the available video ports as in OPEN. SEND DATA 1
contains an 8 bit signed number representing PORT.
The SELECT PORT command selects a Signal Port from the signal ports that
are currently opened by this communications port. All subsequent commands
arriving at the associated RS-422 port will be routed to the assigned Signal Port
until another SELECT PORT command is received. Only one signal port may
be selected by a single communications port at any time. A CLOSE, or SELECT
PORT command following, breaks or closes this selection. PORT is a number
representing the available I/O signal ports. SEND DATA 1 contains an 8 bit
signed number representing PORT.
The PLAY CUE command causes the selected port to prepare to play the
specified ID.
This command is similar to the CUE command but allows play out of just a part
of the ID.
The ID DELETE command is used to remove material from the disk system.
The Signal Ports consist of audio and video channels as configured by the
device. Any signal port can be controlled from any RS-422 control port with the
following Port assignment commands; OPEN, CLOSE and SELECT. Only one
communications port can have a given signal port open at a given time. The
system commands are organized with reference to the Signal Port that they
effect. The ports consist of SIP (Signal Input Ports, range –1 to -127) and SOP
(Signal Output Ports range 1 to 127).
