Computer
Level III programs are developed on a
computer. Commands are sent to the
player directly from the computer to
control a specific videodisc or compact
disc. In addition to providing interactive
control of the player, the computer can
also send graphic overlays to the video
monitor, provide access to a
computer database, etc.
(See
Chapter 4
and
Appendix A
.)
For detailed information about Computer Control of the CLD-V2600 and the CLD-V2400,
see
Chapter 4 and Appendix A of this manual.
LEVEL
3
Level III programs are used to control the player from an external computer attached to the player’s
RS-232C port. The player’s Level III mnemonic command set is used to develop interactive programs
for the CLD-V2600 or the CLD-V2400. (See
Section 4.4 on pages 4-5 and 4-6 or Appendix A for
the list of mnemonic commands available.) Level III mnemonic commands are also used to control
the LD-V8000, the LD-V4400, and the LD-V2200 (NTSC players), LD-V4200 (discontinued NTSC
player), the CLD-V2300D and the LD-V4300D (NTSC/PAL players), and the LD-V4100 (PAL player).
See
Technical Bulletin #143 , Comparative Mnemonic Command Chart. Level III is often used
when a program designer wants users to access a large database from a computer, along with video
and audio material on a disc. Level III requires that a computer be connected to every player. A file
server may be used to network the computers at the various workstations.
