One of the more reliable sources in television technology information and history is Mark Schubin. From his perch in New York City this renowned television engineer and historian administers a number of important consulting and advisory assignments here and abroad. His much sought-after views and wisdom can also be found in numerous publications, including his own e-mail distributed "Mark's Monday Memo" (while generally available his "memo" is directed to the professional ranks).

A pod-cast series highlighting the technology choices made for HDTV was recently initiated by Schubin and CMP Entertainment Media (for which he also writes). The current issue is of a particular interest to those seeking a scientific understanding of those things that influenced system choices for HDTV. Schubin brings obscure knowledge to the surface in a clear, concise audio explanation, one which can be played over and over again until the subject is mastered. I recommend this issue as it will aid you in your own understanding of TV resolution, contrast ratios, and what you see at what viewing distances.

As a companion to the podcast you will find a series of referenced web sites about the visibility of HDTV.

About Dale Cripps

Dale Cripps is a professional journalist who has focused two thirds of his career on the subject of high-definition television. Upon completing his education in business and service in the military he formed Cripps and Associates, South Pasadena, California, in 1964, which operated as a market-development company for aerospace services. In 1983 he turned to television and began what has become a 20 year campaign to pioneer HDTV. For fifteen of those years he published the well-regarded HDTV Newsletter (an international monthly written for television professionals). During much of this same time he also served as the HDTV-Technical Editor for "Widescreen Review Magazine." On November 16, 1998 he launched the Internet distributed HDTV Magazine, which remains the only consumer publication devoted exclusively to high-definition television. In April of 2002 he co-founded with Tedson Meyers of Coudert Bros, the High-definition Television Association of America, which is presently based in Washington DC. Cripps is the president of this organization. Mr. Cripps is a charter member of the Academy of Digital Television Pioneers and honored by that organization with the DTV Press Leadership Award of 2002. He makes his home in Oregon.
