Leader has prepared a presentation titled "Digital and HDTV Primer" that includes a handout package that will be presented at selected venues in addition to the Road Show.   The Digital & HDTV Primer assumes the participant is familiar with NTSC. It will briefly explain the meaning of component video and relate this back to RGB for improved understanding, then move on to explain quantizing and its effects (how the number of bits effect video for example) and move on to describe parallel video and how it is serialized. The connection between analog video (with sync information) and digital video (no sync, anc data space, TRS/EAV/SAV) will be shown a discussion of the various video levels (will relate them to a SMPTE or color bar for SD and HD) and how and why the levels are different between analog, SD and HD will be conducted.   Once this has been explained, time permitting, we will discuss serializing and the eye pattern as well as offer a couple of technical notes on system timing (between SD and HD).   This presentation should be useful to most video engineers that are not experienced with digital yet; for those with good digital experience, it could be a good reminder of what they already know.
