激光灯中的ILDA接口定义

Introduction

As the trade organization for the laser display industry， ILDA’s members represent the entire gamut of how laser shows have been produced. There have been almost as many hardware variations， configurations and protocols as there have been people producing laser light shows. The advantage of the association within ILDA is that over time， from the assortment of ideas and procedures amongst its members， gradually the best ideas percolate out and consensus of opinion is formed. From this consensus， standards have been and will continue to be established which will be beneficial to all who use them.

The ultimate goal of these standards is to ensure the compatibility and interchangeability of hardware， software， and artware， in order that the results are predictable and that the artwork is faithfully reproduced from system to system. Additional benefits also arise from standardization， such as cheaper and more reliable hardware， immediate plug-and-play artware， simplified trouble-shooting， to mention just a few.

This document sets forth the general specifications for the manufacture and production of the ILDA Standard Projector， or “ISP”。 Defining the ISP has been a goal for some time and these specifications represent the culmination of the ILDA’s work for the past few years. Utilizing standards already in place， in conjunction with new standards specifically tailored to the ISP， there is now a definition for a standard projector ensuring a platform that can faithfully reproduce artwork within the inherent limitations of the given projector.

The two key concepts here are “faithfully reproduce” and “the inherent limitations of the given projector.” To illustrate these concepts， consider television. There are a great variety of television sets， ranging from monochrome， pocket-sized LCD sets to full-color projection TVs， all the way to video walls and Jumbotrons. But each of these operates within a set of standard parameters. They accept the same type of signal source and reproduce it within their inherent limitations.
