Robbie-KB6CJZ and I have been invited to give a presentation on Digital-ATV.  
Rather than spend time and money to fly to Chicago for the talk, Robbie and 
I will be making the presentation remotely using PowerPoint via Skype and 
WebEx from the comforts of our homes in Orange County. 

The presentation is entitled: “Planning a Digital-ATV Station for DVB-S” 

Here is the ABSTRACT for the DATV presentation that will be made by us at DCC 
and available in the DCC Proceedings: 

“Most ham radio Amateur Television (ATV) stations and repeaters in use today 
still utilize analog technology. The purpose of this paper is to explain 
Digital-ATV (DATV) to other hams with the hope that it might make the 
transition from analog-ATV to Digital-ATV a little more straightforward. The 
paper begins with a review and comparison of various commercial DTV standards 
that are in use around the world. A top-down design methodology session is 
then conducted to sort through a number of design alternatives to plan a DATV 
station. The planning session chooses the DVB-S standard for DATV over the 
competing United States-based ATSC standard. The paper concludes by 
describing the Forward-Error-Correction factors and Symbol-Rate factors that 
determine the RF bandwidth for a DVB-S DATV station.“
