An exemplary global listings format (GLF) is metadata for electronically transferring multimedia programming content and electronic program guide information. The GLF metadata specifies a self-referential data structure having a self-consistency mechanism comprising interlocking and crosslocking data elements. The self-consistency mechanism ensures completeness and validity of transferred programming data. In one implementation, the exemplary GLF is expressed in an extensible markup language (XML) schema definition (XSD) specification.

Global listings format (GLF) for multimedia programming content and electronic program guide (EPG) information

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.
