1.2 Player Control Methods
The LD-V4400 player can be used for any operations under
control. The LD-V4400 does not have built in Level II capability. The three control
methods commonly referred to in the industry are:
• Level I — Manual Control using a Remote Control Unit (RU-V103),
using a Pioneer Barcode Reader, such as the UC-V108BC or the
UC-V1109BC, or using the player's Front Panel Buttons.
• Level II — Internal Program Control by loading Level II programs into a
Level II compatible player's memory. Usually the programs are specially
encoded onto a Level II videodisc.
• Level III — External Computer Control by sending commands from an
external computer to the player via the RS-232C serial interface.
Levels I, II and III describe the delivery platforms for interactive videodisc applications:
• A Level I system consists of a videodisc player and a monitor. It is
controlled by using a remote control unit or a Laserbarcode Reader or
the front panel buttons on the player. Level I is used mainly for playing
videodiscs continuously, for simple searches, for searching to and
stepping through a specific series of still frames, or for playing discrete
motion video segments.
• Level II systems are comprised of various hardware configurations. A
Level II system usually consist of only a videodisc player with a
programmable memory, such as the LD-V8000, a monitor and a remote
control unit. However, Level II systems can include additional hardware
such as 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
a program specially encoded Level II videodisc, or by sending ASCII-Hex
commands to the player's memory from the remote control unit or via the
RS-232C interface from an external computer. The LD-V4400 videodisc
player does not support Level II applications by itself.

User's Manual/ Programmer's Reference Guide, TP 114 v.1.1 8/92,
available through Pioneer Communications of America, Inc., Multimedia
Systems Division, Engineering/Technical Support, 201-327-6400.
• 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.
See Figures 1-A, 1-B, 1-C, on pages 1-3 through 1-5 for diagrams of Level I and
Level III hardware configurations using the LD-V4400.
