Abstract: 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.

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.

Abstract: An enhanced television navigation service supplies broadcast television music programming, digital audio and related content. The related content is linked with the broadcast programming and is presented to the user. By linking the related content with the programming in this fashion, the user can tune to a program based on information indicators presented by the service.

Abstract: A television service enables enhance Digital Video Recording (DVR) capability by providing content in conjunction with broadcast television programming. The content is associated with the broadcast television programming to enable record and/or playback one or more programs in various modes of operation.

Abstract: An enhanced television navigation service supplies Internet protocol (IP) content with broadcast television programming. The IP content is linked with the broadcast television programming and is presented to the viewer in an enhanced viewing mode. By linking the real time data in this fashion, the user can tune to a program based on information indicators presented by the service.

Abstract: A system for delivering television services provides enhanced content with broadcast television programming. The enhanced content includes event identifiers to enable an association with the broadcast television programming.
