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.
