Since I work as an engineer for Electrohome Projection |

| screens – using 8” CRT projectors in the 31.5 kHz categor y |
| ||||||
Systems, an exhibitor at the show, my view of Infocomm is |
|
| ||||||
| and 9” CRT projectors in the 64 kHz category. Video mater- |
| ||||||
that of an industry insider, an advantageous perspective from |
| ial consisted of colorbar and multiburst test patterns, color |
| |||||
which to report the event. Of course, it carries with it the dan- |
| and |

ger that I could be perceived as biased toward my company’s |
|

products or against those of its competitors. To set this aside, |

let me assure the reader that, apart from supplying a relative- |
