## Background
CROSS REFERENCE TO RELATED APPLICATION
This application is a continuation of U.S. patent application Ser. No. 11/391,958, filed Mar. 28, 2006, which is currently pending, and claims the benefit of U.S. provisional patent application No. 60/667,265, filed Mar. 31, 2005, which are hereby incorporated by reference herein in their entireties.


BACKGROUND OF THE INVENTION
This application relates to interactive media guidance applications and more particularly to interactive media guidance applications implemented on mobile user equipment.
An interactive media guidance application implemented on mobile user equipment allows a user to access media information from any location where the mobile user equipment is in communication with a network.
Recent advances in mobile technology have resulted in the emergence of location-based services that can determine a user's location using technologies such as, for example, global positioning system (GPS) triangulation, or radio-frequency (RF) multipath fingerprinting. An example of a location-based service that is becoming more common in mobile phones is the ability to locate an individual who has dialed an emergency number (e.g., 9-1-1).
Media information, such as, for example television program listings may be region specific and the user may wish to obtain media information for the user's current location. It may be desirable to use location-based services to allow an interactive media guidance application to retrieve and display media information based on the user's current location.
SUMMARY OF THE INVENTION
An interactive media guidance application may be implemented on mobile user equipment that is capable of performing location-based services. In some embodiments, the mobile user equipment may include a GPS sensor that communicates with one or more GPS satellites to pinpoint the user's current location. In some embodiments, the mobile user equipment may request that the network to which it is connected perform network-based techniques such as triangulation, RP multipath fingerprinting, or any other suitable technique to determine the user's current location.
In response to determining the user's current location, the interactive media guidance application may send a request to a media database to obtain media information for the user's current location. For the purposes of simplification and not limitation, the media database will be discussed herein primarily as a program listings database that provides program listings information, although any other suitable media database or combination of media databases may be used.
As part of the request, the interactive media guidance application may provide the program listings database with the user's current location in any suitable format that is accepted by the program listings database (e.g., ZIP code, city and state, area code, etc.). The program listings database may respond by transmitting program listings information for the specified location to the interactive media guidance application, which may than be displayed by the interactive media guidance application.
The interactive media guidance application may continue to update the program listings information at periodic intervals. Alternatively, the user may manually initiate an update of program listings information.
Further features of the invention, its nature and various advantages will be more apparent from the accompanying drawings and the following detailed description of the preferred embodiments.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
The amount of media available to users in any given media delivery system can foe substantial. Consequently, many users desire a form of media guidance, an interface that allows users to efficiently navigate media selections and easily identify media that they may desire. An application that provides such guidance is referred to herein as an interactive media guidance application or, sometimes, a guidance application.
Interactive media guidance applications may take various forms depending on the media for which they provide guidance. One typical type of media guidance application is an interactive television program guide. Interactive television program guides are well-known, guidance applications that, among other things, allow users to navigate among and locate television programming viewing choices and, in some systems, digital music choices. The television programming (and music programming) may be provided via traditional broadcast cable, satellite, Internet, or any other means. The programming may be provided on a subscription basis (sometimes referred to as premium programming), as pay-per-view programs, or on-demand such as in video-on-demand (VOD) systems.
With the advent of the internet, mobile computing, and high-speed wireless networks, users are able to access media on personal computers (PCs) and devices on which they traditionally could not. Non-television-centric platforms (i.e., platforms that distribute media with equipment not part of the user's broadcast, cable or satellite television-delivery network) allow users to navigate among and locate desirable video clips, full motion videos (which may include television programs), images, music files, and other suitable media. Consequently, media guidance is also necessary on modern non-television-centric platforms. For example, media guidance applications may be provided as online applications (i.e., provided on a web-site), or as stand-alone applications or clients on user equipment devices, such as, for example, hand-held computers, personal digital assistants (PDAs), cellular telephones, or traditionally-passive devices that have been enhanced with circuitry for operating interactive media guidance applications (e.g., wrist watches, telephone hand sets, appliances, etc.). In some systems, users may control equipment remotely via a media guidance application. For example, users may access an online media guide and set recordings or other settings on their in home equipment. This may be accomplished by the online guide controlling the user's equipment directly or via another media, guide that runs on the user's equipment. Remote access of interactive media guidance applications is discussed in greater detail in Bills et al. U.S. Patent Publication No. 2005/0028208-A1, which is hereby incorporated by reference herein: in its entirety.
An illustrative interactive media guidance system 100 in accordance with the present invention is shown in FIG. 1. System 100 is intended to illustrate a number of approaches by which media of various types, and guidance for such media, may be provided to (and accessed by) end-users. The present invention, however, may be applied in systems employing any one or a subset of these approaches, or in systems employing other approaches for delivering media and providing media guidance.
System 100 may include any one or more of mobile user equipment 108, user television equipment 110, and user computer equipment 112. Mobile user equipment 108 may be any suitable mobile device including, for example, a cellular phone, a personal digital assistant (PDA), a laptop computer, a handheld computer, a mobile media player, a wireless e-mail device, and a vehicle-based media system. In some embodiments, mobile user equipment 108 may include a GPS sensor that communicates with a plurality of GPS satellites 150 to determine the location of mobile user equipment 108. An illustrative embodiment of mobile user equipment 108 is discussed below in greater detail in connection with FIG. 2.
User television equipment 110 may include, for example, a television and any one or more of a set-top box and a recording device. User computer equipment 112 may be any suitable computing device including for example, a desktop computer, laptop computer, and handheld computer. Illustrative embodiments of user television equipment 110 and user computer equipment 112 (FIG. 1) are discussed in greater detail in Thomas et al. U.S. Patent Application Publication No. 2005/0120373 A1, which is hereby incorporated by reference herein in its entirety.
The first approach represents a typical television-centric system in which users may access media (e.g., television programming and/or digital audio). This includes programming sources 102 and distribution facility 104. Media is provided from programming sources 102 to distribution facility 104, using communications path 106. Communications path 106 may be a satellite path, a fiber-optic path, a cable path, or any other suitable wired or wireless communications path or combination of such paths.
Programming sources 102 may be any suitable sources of television and music programming, such as television broadcasters (e.g., NBC, ABC, and HBO) or other television or music production studios. Programming sources 102 may provide television programming in a variety of formats in high definition and standard definition, such as, for example, 1080p, 1080i, 720p, 480p, 480i, and any other suitable format. There are typically numerous programming sources 102 in system 100, but only one is shown in FIG. 1 to avoid overcomplicating the drawing.
Distribution facility 104 may be a cable system headend, a satellite distribution facility, a television broadcaster, or any other suitable facility for distributing video media (e.g., television, programs, video-on-demand programs, pay-per-view programs) and audio media (e.g., music programming and music clips) to the equipment of subscribers of the corresponding cable, satellite, or Internet protocol television (IPTV) system. In some approaches, distribution facility 104 may also distribute other media to users, such as video and audio clips, web pages, and interactive applications, that may be offered to subscribers of a given cable, satellite, or IPTV system. There are typically numerous distribution facilities 104 in system 100, but only one is shown in FIG. 1 to avoid overcomplicating the drawing.
Distribution facility 104 may be connected to user television equipment 110 and user computer equipment 112.
User equipment devices 110 and 112 may receive media (such as television programs, music, web pages, etc.) and other data from distribution facility 104 over communications paths, such as communications paths 116 and 118, respectively. User equipment devices 110 and 112 may also transmit signals to distribution facility 104 over paths 116 and 118, respectively. Paths 116 and 118 may be cables or other wired connections, free-space connections (e.g., for broadcast or other wireless signals), satellite links, or any other suitable link or combination of links.
A second approach illustrated in FIG. 1 by which media and media guidance axe provided to end users is a non-television-centric approach. In this approach, media such as video (which may include television programming), audio, images, web pages, or any suitable combination thereof, are provided to mobile user equipment 108, user television equipment 110, and user computer equipment 112 by server 130 via communications network 126. This approach is non-television centric because media (e.g., television programming) is provided by and delivered at least partially, and sometimes exclusively, via equipment that have not traditionally been primarily focused on the television viewing experience. Non-television-centric equipment is playing a larger role in the television viewing experience.
In some embodiments for this approach, communications network 126 is the Internet, Server 130 may provide for example, a website that is accessible to the user's equipment and provides an online guidance application for the user. In such approaches, the user's equipment may be, for example, a PC or a hand-held device such as a PDA or web-enabled cellular telephone that incorporates a web browser. In other embodiments, server 130 uses the Internet as a transmission medium but does not use the Web. In such approaches, the user's equipment may run a client application that enables the user to access media. In still other approaches, communications network 126 is a private communications network, such as a cellular phone network, that does not include the Internet.
In yet other approaches, communications network 126 includes a private communications network and the Internet. For example, a cellular telephone or other mobile-device service provider may provide Internet access to its subscribers via a private communications network, or may provide media such as video clips or television programs to its subscribers via the Internet and its own network.
The aforementioned approaches for providing media may, in some embodiments, be combined. For example, a distribution facility 104 may provide a television-centric media delivery system, while also providing users' equipment (e.g., 110 and 112) with access to other non-television-centric delivery systems provided by server 130. For example, a user's equipment may include a web-enabled, set-top box or a television enabled PC. Distribution facility 104 may, in addition to television and music programming, provide the user with Internet access whereby the user may access server 130 via communications network 126. Distribution facility 104 may communicate with communications network 126 over any suitable path 134, such as a wired path, a cable path, fiber-optic path, satellite path, or combination of such paths.
Media guidance applications may be provided using any approach suitable for the type of media and distribution system for which the applications are used. Media guidance applications may be, for example, stand-alone applications implemented on users' equipment. In other embodiments, media guidance applications may be client-server applications where only the client resides on the users' equipment. In still other embodiments, guidance applications may be provided as web sites accessed by a browser implemented on the users' equipment. Whatever the chosen implementation, the guidance application requires information about the media for which it is providing guidance. For example, titles or names of media, brief descriptions, or other information may be necessary to allow users to navigate among and find desired media selections.
In some television-centric embodiments, for example, the guidance application may be a stand-alone interactive television program guide that receives program guide data via a data feed (e.g., a continuous feed, trickle feed, or data in the vertical blanking interval of a channel). Data source 120 in system 100 may include a program listings database that is used to provide the user with associated program data such as schedule information, program descriptions, program information (e.g., actors, directors, release date, ratings, genre, etc.), related articles, interviews, reviews, metadata having links to related content, descriptive metadata, and other similar content or data relating to the television programs. In some embodiments, the data may also include content or video related to television programs. Data source 120 may also be used to provide promotions and advertisements (e.g., program guide advertisements and promotions for television programs), real-time data such as sports scores, stock quotes, news data, and weather data, application data for one or more media, guidance applications or other interactive applications, and any other suitable data for use by system 100. As another example, data source 120 may provide data indicating the types of information that may be included in interactive media guidance overlays (e.g., at the request of the user, absent user modification, etc.).
Program guide data may be provided to user equipment using any suitable approach. For example, program schedule data and other data may be provided to the user equipment on a television channel sideband, in the vertical blanking interval of a television channel, using an in-band digital signal, using an out-of-band digital signal, or by any other suitable data transmission technique. Program schedule data and other data may be provided to user equipment on multiple analog or digital television channels. Program schedule data and other data may be provided to the user equipment with any suitable frequency (e.g., continuously, daily, in response to a request from user equipment, etc.).
In some television-centric embodiments, guidance data from data source 120 may be provided to users' equipment using a client-server approach. For example, a guidance application client residing on the user's equipment may initiate sessions with server 140 to obtain guidance data when needed.
There may be multiple data sources (such as data source 120) in system 100, although only one data source is shown in FIG. 1 to avoid overcomplicating the drawing. For example, a separate data source may be associated with each of a plurality of television broadcasters and may provide data that is specific to those broadcasters (e.g., advertisements for future programming of the broadcasters, logo data for displaying broadcasters, logos in program guide display screens, etc.). Data source 120 and any other system components of FIG. 1 may be provided using equipment at one or more locations. Systems components are drawn as single boxes in FIG. 1 to avoid overcomplicating the drawings.
Data source 120 may provide data to distribution facility 104 over communications path 122 for distribution to the associated user equipment over paths 116 and 118 (e.g., when data source 120 is located at a main facility). Communications path 122 may foe any suitable communications path such as a satellite communications path or other wireless path, a fiber-optic or other wired communications path, a path that supports Internet communications, or other suitable path or combination of such paths.
Data source 120 may also provide guidance data directly to mobile user equipment 108 (over path 124, communications network 126, and path 128), user television equipment 110 (over path 124, communications network 126, and path 136), and user computer equipment 112 (over path 124, communications network 126, and path 130). Paths 124, 128, 136, and 138 may be wired paths such as telephone lines, cable paths, fiber-optic paths, satellite paths, wireless paths, and any other suitable paths or a combination of such paths. Communications network 126 may be any suitable communications network, such as the Internet, the public switched telephone network, or a packet-based network.
Mobile user equipment 108, user television equipment 110, and user computer equipment 112 may use the program schedule data and other interactive media guidance application data to display program listings and other information (e.g., information on digital music) for the user. An interactive television program guide application or other suitable interactive media guidance, application may be used to display the information on the user's display (e.g., in one or more overlays that are displayed on top of video for a given television channel). Interactive displays may be generated and displayed for the user using any suitable approach. In one suitable approach, distribution facility 104, server 130, or another facility, may generate application display screens and may transmit the display screens to user equipment for display. In another suitable approach, user equipment may store data for use in one or more interactive displays (e.g., program schedule data, advertisements, logos, etc.), and an interactive media guidance application implemented at least partially on the user equipment may generate the interactive displays based on instructions received from distribution facility 104, server 130 or another facility. In some embodiments of the present invention, user equipment may store only the data that is used to generate the interactive television displays (e.g., storing logo data for a particular television broadcaster only if the logo is to be included in one or more interactive television displays). In some embodiments of the present invention, user equipment may store data that is not necessarily used to generate the interactive television displays (e.g., storing advertisements associated with a particular television broadcaster that may or may not be displayed depending on, for example, the outcome of negotiations with the television broadcaster). Any other suitable approach or combination of approaches may be used to generate and display interactive overlays for the user.
In still other embodiments, interactive media guidance applications (television-centric and non-television centric) may be provided online as, for example, websites. For example, server 130 may provide an online interactive television program guide. As another example, user computer equipment 112 may be web-enabled to allow the user to access an online guidance application (which may be modified from its original version to make it appropriate for user computer equipment 112). Alternatively, user computer equipment 112 may have an applet that communicates with server 130 to obtain guidance data via the Internet.
Server 130 may receive program schedule data and other data from data source 120 via communications path 124, communications network 126, communications path 132, or another suitable path or combination of paths. Path 132 may foe a satellite path, fiber-optic path, wired path, or any other path or combination of paths. Mobile user equipment 108 may access the online interactive media guidance application and other sources from server 130 via communications path 128, Mobile user equipment 108 may also access the application and other services on server 130 via communications path 114, distribution facility 104, and communications path 134.
User equipment such as user television equipment 110 and user computer equipment 112 may access the online interactive media guidance application and server 130 using similar arrangements. User television equipment 110 may access the online interactive media guidance application and server 130 using communications path 136 or using path 116, distribution facility 104, and path 134. User computer equipment 312 may access the online interactive media guidance application and server 130 using communications path 138 or using path 116, distribution facility 104, and path 134. Paths 136 and 138 may be any suitable paths such as wired paths, cable paths, fiber-optic paths, wireless paths, satellite paths, or a combination of such paths.
If desired, an interactive media guidance application such as a network-based video recorder or a video-on-demand application may be supported using server 140, server 130, or equipment at service provider 142. Video-on-demand content and video recorded using a network-based video recorder arrangement may be stored on server 140, server 130, or at service provider 142 and may be provided to the user equipment when requested by users. An interactive television program guide, for example, may be used to support the functions of a personal video recorder (sometimes called a digital video recorder) that is implemented using user television equipment 110 or user computer equipment 112. Illustrative equipment that may be used to support personal video recorder functions include specialized personal video recorder devices, integrated receiver decoders (IRDs), set-top boxes with integrated or external hard drives, or personal computers with video recording capabilities.
FIG. 2 shows an illustrative embodiment of mobile user equipment 108 in accordance with the present invention. Mobile user equipment 103 may include control circuitry 202, input/output 204, display 210, speakers 212, user input interface 214, and OPS sensor 218.
Control circuitry 202 may include processing circuitry 206 and storage 208. Processing circuitry 206 may be any suitable processor such as, for example, a microprocessor, a microcontroller, a digital signal processor, or a programmable logic device. Storage 208 may be any suitable storage device or combination of suitable storage devices including, for example, a magnetic storage device, solid state memory, or an optical disk drive. Storage 208 may be controlled by processing circuitry 208 to store or retrieve data.
Input/output 204 may include a wireless transceiver that allows mobile user equipment 108 to communicate wirelessly with communications network 126 (FIG. 1). Input/output 204 may be used to transmit requests to network processors (e.g., server 130 or 140) and receive information from media databases (e.g., server 130 or 140).
A user may control control circuitry 202 using user input interface 214. User input interface 214 may be any suitable user interface, such as a mouse, trackball, keypad, keyboard, touch screen, touch pad, voice recognition interface, or a remote control.
Display 210 may be any suitable display device such as, for example, an LCD display. Speakers 212 may be any suitable audio speaker. Display 210 and speakers 312 may be controlled by processing circuitry 206.
An interactive media guidance application may be implemented on mobile user equipment 108. Processing circuitry 206 may execute the interactive media guidance application and direct display 210 to display screens of the interactive media guidance application. The screens of the interactive media guidance application may include menus and options. The user may interact with the menus and options using user input interface 214.
The interactive media guidance application may allow the user to remotely perform program guide functions. In particular, the interactive media guidance application may allow the user to access media information (e.g., program listings information) on mobile user equipment 108. Processor 206 may send a request for media information to a media database (e.g., server 130 or server 140 (FIG. 1)) via input/output 204 and display the received media information on, for example, a media listings screen.
The interactive media guidance application may allow the user to search for media information using various criteria (e.g., title, date, or network). In some embodiments, the interactive media guidance application may search media information stored on storage 208. In some embodiments, the interactive media guidance application may send a search request to a media database (e.g., server 130 or server 140 (FIG. 1)) via input/output 204 and communications network 126. The interactive media guidance application may display a list of media that meet the search criteria.
The interactive media guidance application may also allow the user to set a reminder for a television program. The reminder may be displayed by mobile user equipment 108 to alert the user that the television program is about to begin. In some embodiments, the interactive media guidance application may allow the user to send reminders to another mobile user equipment via input/output 204 and communications network 126. The reminder may foe displayed by the other mobile user equipment prior to the beginning of the television program.
The interactive media guidance application may allow the user to remotely schedule recordings of television programs on recording devices. In some embodiments, mobile user equipment 108 may be associated with user equipment (e.g., user television equipment 110 or user computer equipment 112 (FIG. 1)) having recording capabilities. In some embodiments, the interactive media guidance application may prompt the user to select user equipment with which to record television programs. Processing circuitry 206 may send a command to record a television program to an interactive media guidance application implemented on the user equipment via input/output 204, communications network 126, and media distribution facility 104. Remote recording is discussed in greater detail in Ellis et al. U.S. Patent Publication No. 2005/0028208-A1, which has been incorporated by reference in its entirety.
The interactive media guidance application implemented on mobile user equipment 108 may also be configured to perform location-based services. The location of mobile user equipment 108 may be determined using several different approaches. In one approach, GPS sensor 218 may receive timing signals from a plurality of GPS satellites 150 (FIG. 1). GPS sensor 218 may analyze the received timing signals to determine the distance to each of GPS satellites 150. GPS sensor 218 may calculate the location of mobile user equipment 108 based on the distances to GPS satellites ISO.
In another approach, a network processor (e.g., server 130 or server 140 (FIG. 1)) may triangulate the radio emissions from mobile user equipment 108 to determine the location of mobile user equipment 108.
In yet another approach, the network processor may perform RF multipath fingerprinting by creating a database of fingerprints that correspond to radio emissions transmitted from different locations. The network processor may determine the location of mobile user equipment 108 by matching the received radio emissions to one of the stored fingerprints.
FIG. 3a shows an illustrative screen 300 of an interactive media guidance application implemented on mobile user equipment (e.g., mobile user equipment 108 (FIG. 1)) for providing a user with a menu in accordance with one embodiment of the present invention. Screen 300 may include a settings option 302 and a program listings option 304.
In response to the user selecting settings option 302, the interactive media guidance application may display a screen that allows the user to select, among other things, options for configuring location-based services. An illustrative settings screen is discussed in greater detail below.
In response to the user selecting program listings option 304, the interactive media guidance application may display a screen that includes program listings for a particular geographical region. Illustrative program listings screens are discussed in greater detail below.
Screen 300 may also include additional options, such as, for example, options for allowing the user to select the types of media information to retrieve (e.g., video-on-demand listings, pay-per-view listings, advertisements).
It should be understood by one skilled in the art that options 302 and 304 (and any other options displayed by the interactive media guidance application) may be selected using any suitable user input. For example, the display screen of the mobile user equipment may be touch sensitive and the options may be selected with, for example, a stylus. In another example, the user may use navigation keys on the keypad of the mobile user equipment to select options.
FIG. 3b shows an illustrative screen 310 of an interactive media guidance application implemented on mobile user equipment for selecting settings in accordance with one embodiment of the present invention. As shown in FIG. 3b, screen 310 includes checkboxes 312 and 314 and an OK button 316. Screen 310 may be displayed, for example, in response to the user selecting settings option 302 from screen 300 (FIG. 3a).
The interactive media guidance application may allow the user to select checkbox 312 to enable location-based services. In response to the user selecting checkbox 312, the interactive media guidance application may foe configured to activate circuitry for determining the user's location. For example, the interactive media guidance application may activate a GPS sensor 218 (FIG. 2) on the mobile user equipment. In another example, the interactive media guidance application may instruct a network processor (e.g., server 130 or server 140 (FIG. 1)) to perform a network-based positioning method (e.g., triangulation, RF multipath fingerprinting, etc.) to determine the location of the mobile user equipment.
The interactive media guidance application may allow the user to select checkbox 314 to enable location-based updates of program listing information. In some embodiments, the interactive media guidance application may only allow the user to select checkbox 314 if the checkbox 312 has already been checked. In response to the user selecting checkbox 314, the interactive media guidance application, may be configured to update program listings information based on the user's current location. In some embodiments, the interactive media guidance application may automatically update program listings information for the user's current location at periodic intervals. In response to automatically updating program listings information, the interactive media guidance application may display the updated program listing information to the user.
The interactive media guidance application may allow the user to select OK button 316 to save the settings selected by the user.
It should be understood by one skilled in the art that screen 310 may include additional options without departing from the scope of the present invention. For example, screen 310 may include options allowing the user to select settings relating to automatically updating program listings information at periodic intervals or receiving a user prompt to update the program listings information.
In another example, screen 310 may include options for allowing the user to select the amount of program, listings information to retrieve when performing a location-based update (e.g., program listings for the next hour, program listings for the next six hours, program listings for favorite channels, etc.).
In another example, screen 310 may include options for allowing the user to select to update other types of media information or combinations of media information, including, for example, pay-per-view and video-on-demand listings, advertisements, etc.
FIG. 3c shows an illustrative screen 320 for displaying program listings information, in an interactive media guidance application implemented on mobile user equipment in accordance with one embodiment of the present invention. Screen 320 includes location area 322, date/time area 324, program listings, area 326, and advertisement area 328. Screen 320 may be displayed, for example, in response to the user selecting program listings option 304 from screen 300 (FIG. 3a).

For example, if the GPS sensor has provided the user's location in a latitude/longitude format and the media database accepts ZIP codes, the interactive media guidance application may determine the SIP code corresponding to the latitude and longitude for the user's current location. In particular, the interactive media guidance application may send a request to a server to convert the location information to a ZIP code or the interactive media guidance application may perform the conversion by referring to data correlating latitude and longitude information with SIP codes.
At step 410, if there is more than one service provider for the user's current location, the interactive media guidance application may receive a listing of service providers for the user's current location. Service providers may include broadcast, cable, satellite providers, fiber optic, online, and any other suitable service providers.
At step 411, the interactive media guidance application may determine whether the user has previously selected one of the service providers for the current location.
At step 412, if the user has previously selected one of the service providers for the current location, the interactive media guidance application automatically selects the previously selected service provider from which to receive media information. For example, the user may currently be located in Minneapolis, Min. If the user was in Minneapolis a week ago and previously selected to receive media information for television broadcast providers, the interactive media guidance application may automatically select to receive media information for television broadcast providers in accordance with the user's previous selection.
In some embodiments, the user may select to receive media information for a service provider for all locations. The interactive media guidance application may automatically select, to receive media information for the default service provider.
Alternatively, at step 414, if the user has not previously selected one of the service providers for the user's current location, the interactive media guidance application prompts the user to select a service provider for which to receive media information. For example, as shown in FIG. 3e, the interactive media guidance application may display a dialog box prompting the user to select a service provider for which to receive media information.
At step 416, the interactive media guidance application may receive media information for the selected service provider from the media database.
