In most cases, a translator system is implemented to enhance the DTV signal coverage that is limited by shadowing, multipath interference, and power. This paper reviews DTV translator technologies, discusses concerns and issues faced by today’s DTV broadcasters, and proposes a new 8-VSB Digital On-Channel translator concept.

A Revenue Opportunity for Digital Translators

by A Hwang and S Kuh
 

TV Translators are the best way to provide the free over-the-air television services to rural households located in areas with geographic barriers. However, the current transition to Digital TV (DTV) may take a long time due to higher cost of ownership for both DTV Translator operators and the rural viewers. This paper proposes a possible business model for DTV Translator operators.
