LD-V8000 Level II • Chapter One

1 Introduction

Before you use the LD-V8000, please read the safety information contained in the
Operating Instructions packaged with the player. For an overview of the three
player control methods: Level I, II and III, and for more details on player Operational
Basics, refer to the Pioneer LD-V8000 Level I & III User's Manual / Programmer's
Reference Guide , Technical Publication 113 Version. 2.0 3/91.
1.1 Level II and the LD-V8000
Although several earlier Pioneer Industrial Videodisc Players contained
programmable memory allowing for the execution of Level II programs, added
features of the Pioneer LD-V8000 now provide even more advanced Level II
capabilities. This LD-V8000 Level II User's Manual/Programmer's Reference
Guide provides information to assist programmers in the development of Level II
program applications for Pioneer's model LD-V8000 industrial videodisc player.
The LD-V8000 is a highly flexible, programmable playback system that employs a
laser to read video and audio program material from a rotating videodisc. An
internal microprocessor controls all phases of the Pioneer LD-V8000's operation,
processing external commands, internally-stored commands, and internally
generated control and status signals. The microprocessor makes possible the
player's many "Play", "Search", and "Display" functions. The player includes 7K of
user-accessible Random Access Memory (RAM), allowing for the presentation of
significant player-controlled interactive videodisc applications.
Because the LD-V8000 is programmable, the exact sequence and display of
information presented to the viewer can be predetermined by an interactive
program designer and computer programmer. Audio-visual applications developed
for a wide variety of uses may be executed by the player's internal microprocessor.
Properly constructed "stand-alone" Level II programs allow a wide range of
dynamic viewer interactions with the displayed material. This Level II program
may be loaded onto the player manually, downloaded from a computer, or read
from a Level II videodisc.
When a videodisc is manufactured with a properly formatted "Level II" program
encoded in the first few seconds of its Audio Channel 2, it is referred to as a Level
II disc. In addition to the normal Audio and Video, the Level II disc contains
computer readable instructions that define all, or part of, an interactive
application. Interactive programs stored within and executed by the LD-V8000 are
referred to as Level II programs, even if they do not require a Level II disc.
When a Level II videodisc is spun-up on the LD-V8000, its Level II program can be
automatically loaded into the player's memory. When executed, the program will
tell the player what audio and video to present, and how to respond to user inputs.
