9、d Foreword ISO (the International Organization for Standardization) and IEC (the International Electrotechnical Commission) form the specialized system for worldwide standardization. National bodies that are members of ISO or IEC participate in the development of International Standards through tech
10、nical committees established by the respective organization to deal with particular fields of technical activity. ISO and IEC technical committees collaborate in fields of mutual interest. Other international organizations, governmental and non-governmental, in liaison with ISO and IEC, also take pa
11、rt in the work. In the field of information technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of the joint technical committee is to prepare Inte
12、rnational Standards. Draft International Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication as an International Standard requires approval by at least 75 % of the national bodies casting a vote. Attention is drawn to the possibility that some
13、 of the elements of this document may be the subject of patent rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights.

15、and light valve system, and data projectors having a computer signal input port capable of projecting the image outputs from a computer, VCR or other devices. NOTE 1 It also covers Data projectors that have a video signal input port as well as a computer signal input port. NOTE 2 It is not applicabl
16、e to units with a rear projection system or with a video input terminal alone. 2 Terms and definitions For the purposes of this document, the following terms and definitions apply. 2.1 light valve a system which creates an optical image by electrical means using light from a separate source 2.2 tele
