1.0 Foreword
The PRV-LX1 can be controlled externally using IEEE-1394 commands. Control is applied through the
4-pin connection located on the rear of the recorder. Set the IEEE-1394 REMOTE controls through the
main menu. With a monitor connected to the PRV-LX1, press the Function button on the PRV-LX1’s
front panel to access the menu. Control Settings are accessed through the Setup/Operation menu.
Note: This document is valid for PRV-LX1 System Version 3.01/1.04 or later.
Note: The recorder’s DV Recording must be set for Remote (under Status > Control Settings > Control) to
have the unit recognize IEEE-1394 external control options (see image below).

If the PRV-LX1 receives this command while in a Stop condition, the title specified by TT is deleted: With
"01:20:00:00:E0: 36:8F Mode Sense" command, it is possible to know if the deletion process is complete.
Issue the "01:20:00:00:E0: 36:81 Title Number Sense" command before and after the deletion to confirm
that the number of titles in the selected project have been reduced. If the number of titles has not been
reduced, the title deletion has failed so error handling should be executed. Data format is same as the

5.0 Procedure for Issuing Command
PRV-LX1 IEEE-1394 Protocol
Example: playing Title 2, from the scene10 minutes to 20 minutes
“Drive Select” and “Selecting the project” are not available when using the remote control. Issue a
"01:20:00:00:E0: 36:81:00:00 “Title Number Sense" command from Stop to get the total number of titles for the
current project.
Total time of the title cannot be acquired directly by a remote command. However, when a title is played by
remote commands (e.g. "0C: 20:C4: 75 Fast Forward"), the title is Paused at the end of the title. To calculate the
total time of the title, use the "01:20:51:71:FF: FF: FF: FF Medium Position Inquiry Time-code" command fwhen
PAUSE is returned by the "01:20:D0: 7F Mecha-Mode Status Inquiry" command.
Page 9 of 12
PRV-LX1 IEEE-1394 Protocol
Example: playing Title 2, while recording title 3 to HDD
On HDD Rec, it is possible to play a title other than the recording title when Time Shift PLAY setting is Enable.
The “00:20:C4:60 Stop” command stops Play during recording using TimeShift PLAY and stops recording when in
the Rec condition. It is not possible to start recording while in Playback or to stop recording directly durin g TimeShift PLAY. To stop Time-Shift PLAY, first stop recording.

6.0 Product-Specific Notes
6.1 Recording Delay
There is a short delay of approximately 29+/-2 frames between when the PRV-LX1 is issued a record
command and the command is executed.
This delay is a result of the following:
Requires +12 frames for encoding system setup
Execution of the command may take +2 frames
Execution of the command may take–2 frames
Record default offset for the LX1 is 17 frames
The above delay shows the calculation of a maximum +29 frames +/- 2 frames delay.
Pioneer Electronics suggest that PRV-LX1 users pad these frame times to the head/tail of the selected
I/O points to ensure that an entire video sequence is recorded.
PRV-LX1 IEEE-1394 Protocol
Page 11 of 12
6.2 Playback Delay
When the PRV-LX1 is issued a play command it experiences up to a +2 frames delay in the execution of
the command. This delay is a result of the command being sent from the NLE system/edit controller via
serial control to the recorders internal HDD for processing. This action takes approximately 2 frames to
accomplish.
PRV-LX1 IEEE-1394 Protocol
6.3 PRV-LX1 as Recording Device
When issuing a “pause” command while recording, the PRV-LX1 continue s recording within the same
title/clip, maintaining continuous time-code.
To issue a “pause” command the user must issue a “shuttle 0” command. This pauses recording
to insert a chapter mark at the closest GOP of encoded video then recording continues. The
[Auto Chapter] setting should be set to Manual.
Issuing a “stop” command closes the recorded title/clip as defined by the DVD spec. All
subsequent recordings via serial control start with a new title/clip. The PRV-LX1 generates new
time-code within that title/clip.
6.4 PRV-LX1 as Source Device
When the PRV-LX1 is the source device being controlled via serial control with an NLE or edit control
device the following limitation applies.
When an external device is controlling the PRV-LX1 and a “Search and Play” command is sent
via serial control, the PRV-LX1 reports back frame numbers every 50ms. The PRV-LX1 cannot
return the precise time-code. The unit may return the same value as requested earlier or may
skip the frame while Recording or Playing.
* Pioneer Electronics suggest manually recording without using serial control when the
recorder is to be used as a source. Or, if the external control device offers the ability to
change the time-code query speeds, change the devi ce to 50ms to match the PRV-LX1.
