the concepts and operational details in this manual and then refer to Pioneer's
LD-V8000 Level II User's Manual/Programmer's Reference Guide, V. 1.1 8/92,
for internal program control.
The LD-V8000 player can be used for Level I, Level II, and Level III control. The
three control methods are: Level I — Control using a Remote Control Unit (RU-
V6000 or RU-V103), using the player's Front Panel Buttons or using a Pioneer
Barcode Reader (UC-V104BC, UC-V108BC or UC-V109BC). Level II — Control by
loading Level II programs into the player's memory. Level III — Control by sending
commands from an external computer to the player via the RS-232 serial interface.
The LD-V8000 supports the LaserVision Standard for CAV or CLV discs allowing
development of either Level I, II or III applications. It supports the LaserBarcode 2
Command Set for Level I control. It also has an RS-232 interface and uses the
same Level III mnemonic command protocol introduced in the LD-V4200 and also
available in the LD-V2200, CLD-V2400, LD-V4400 and the LD-V4300D. See
Technical Bulletin #143A, for Pioneer Industrial LaserDisc Player Command
Comparison Chart.
1.2 Level I, Level II, and Level III
Levels I, II and III describe delivery platforms for interactive videodisc applications:
• A Level I system consists of a videodisc player and a monitor. It is
controlled by using the front panel buttons on the player, a remote
control unit or a Pioneer Barcode Reader. Level I is used mainly for
playing videodiscs continuously, for simple searches, for searching to a
specific series of frames and stepping through them, or for playing
discrete motion video segments.
• Level II systems are comprised of various hardware configurations. A Level
II system may consist of only a videodisc player with a programmable
memory and a monitor, or a programmable videodisc player, a monitor, a
touch screen, printer, etc. In Level II, these systems are controlled by
loading a Level II program into the memory of the player from either a
program encoded on a videodisc, or by sending ASCII-Hex commands to the
player's memory from the remote control unit or via the RS-232 interface
from an external computer. Not all videodisc players support Level II
applications. See LD-V8000 Level II User's Manual/Programmer's
Reference Guide V. 1.1 8/92.
• A Level III system generally consists of an LD player, a monitor and a
computer. The system is controlled by the computer. This is a complex
interactive system allowing access to computer data as well as access to
audio-video material on the videodisc.
