Abstract
Providing a program guide for digital and analog broadcast television channels specific to a geographic region. A computing device sends a program guide request including a geographic identifier to another computing device. In response, the other computing device filters a master program guide as a function of the geographic identifier to create the requested program guide. The created program guide includes a call sign, physical channel, major channel, and content listing for each of the digital broadcast television channels. In one embodiment, the digital broadcast television channels conform the Advanced Television Systems Committee (ATSC) standard.
