2x.2C - RECORD INIT WITH
DATA
This command is similar to the CUE command but allows play out of just a part of the
ID.
2x.2C - RECORD INIT WITH
DATA
The RECORD INIT WITH DATA command has all the features and requirements of the
RECORD INIT command with the following changes: The ID may already exist on the
disk (e.g. this command permits a dub over of a section of the ID).
3x.01 - OPEN PORT 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).
3x.02 - NEXT The NEXT command is used to transfer any remaining IDs in groups of up to ten. It has
the same format as LIST commands and NEXT is called repeatedly until all IDs have
been transferred. See the LIST command 3X.11 for more details.
3x.05 - PORT STATUS
REQUEST
The Port Status command returns to the controller the status bytes specified for the
selected video port, preceded by the bit map.
3x.06 - POSITION REQUEST The POSITION REQUEST query returns the current position ‘timecode’ or time
remaining within the ID which is currently playing on the selected port. The selected
port must be in PLAY, RECORD, CUED, OR STILL state or an error will be logged. An
error condition will result in the appropriate bit being set in the port status error bytes.
The POSITION/TIME returned is in RETURN DATA 2-5 in FRAMES, SEC, MIN,
HOURS BCD format is preceded by RETURN DATA 1 the time type.
3x.07 - ACTIVE ID REQUEST This command returns information to the controller about whether a queried port is
active (an active port is one that is either recording, playing, cued or cueing), and what
the active ID is. This query does not affect the output of the system.
3x.08 - DEVICE TYPE
REQUEST
The DEVICE TYPE REQUEST command is used to request the specifications of the
Controlled Device. The response to this command is a 16-byte (maximum) data message
advising of the specifications of the CONTROLLED DEVICE. The first N bytes will be
the manufacturer ID followed by a colon ‘:’
3x.10 - SYSTEM STATUS
REQUEST
This command returns to the controller information about the MAIN storage system.This
command returns to the controller information about the MAIN storage system
3x.11 - ID LIST This command returns a list of all IDs currently stored on the system to the controller.
The format will return the number of IDs remaining to be transmitted in subsequent
transmissions in RETURN DATA 1 and RETURN DATA 2 (RETURN DATA 1 MSB,
RETURN DATA 2 LSB), followed by ten 8 byte IDs in RETURN DATA 3 to RETURN
DATA 82. The NEXT command is used to transfer any remaining IDs in groups of up to
ten. NEXT is called repeatedly until all IDs have been transferred.
3x.14 - ID SIZE REQUEST This command returns the duration of the specified ID to the controller. The format
returns the frames in RETURN DATA 1, seconds in RETURN DATA 2, minutes in
RETURN DATA 3 and hours in RETURN DATA 4, in BCD. SEND DATA 1-8 contains
the ID name. This command returns the duration of the specified ID to the controller.
The format returns the frames in RETURN DATA 1, seconds in RETURN DATA 2,
minutes in RETURN DATA 3 and hours in RETURN DATA 4, in BCD. SEND DATA 1-
8 contains the ID name.
