Chapter One • CLD-V2600 / 2400 Level I & III

Level III — External Computer Control

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.

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.
