## Title
Third party service switching through command bar user interface

## Abstract

A graphical user interface allows users to access multiple third party services (e.g., online media services) and enables the services to provide functionality within the GUI adjacent to core functionality of a host application (e.g., a media player application, operating system shell, etc.). The GUI provides an interface region for third party service functionality that is distinct from, but equal in exposure and prominence to, the core functionality provided by the application hosting the GUI. The GUI enables seamless switching between a list of available services provided in a service menu. Switching between services replaces service function buttons and service branding according to particular service customizations.

## Background
RELATED CASES
This application is a continuation in part to U.S. patent application Ser. No. 10/838,645, filed May 3, 2004, titled “Online Service Switching And Customizations”.


TECHNICAL FIELD
The present disclosure generally relates to a graphical user interface, and more particularly to enabling third party service selection, customization, and functionality within regions of the graphical user interface that are adjacent to core functionality being provided by a host application.
BACKGROUND
Most media player applications provide a range of features that enable users to discover, acquire, and use media content. In addition, the exposure to, and use of, media content (e.g., through online media services, etc.) is increasingly becoming part of a user media experience that is relevant to other applications and to an overall operating system environment. With the exception of providing the media content itself, most media players provide and control all aspects of the user experience. That is, the media player controls the experience with respect to discovering and acquiring online media, in addition to providing a broad range of features for using the media, such as playing the media, burning the media (e.g., music files) to a CD, and transferring the media to a portable device.
There are various ways for online media services to advertise and deliver media content to customers/users. For example, in one scenario, users can use a browser application to browse media service Web pages and search for media content, and then purchase and download desired content through the browser application and mechanisms provided by the media service. In this case, the media discovery and acquisition process is generally controlled by the media service itself. From the media service's point of view, being able to control the media discovery and acquisition experience in this manner is a benefit, as it provides the service with the opportunity to attract more users through its own innovative and dynamic presentation of media content.
In another scenario, media services can deliver content to users through agreements made with media player developers. A media service provides the media content, but the media player controls how the user discovers and acquires (and plays/consumes) the content. This lack of control over the discovery and acquisition of its content is problematic for media services, however. Some media services have attempted to overcome this problem by writing their own media players and providing them to users. Although this alternative gives a media service control over the discovery, acquisition and playback of the media content, it also has important disadvantages. In particular, the cost of developing a media player can be significant, which typically means that the resulting media player is unable to offer the rich playback features provided by other media players that are readily available to users.
From a user's view point, both of the scenarios discussed above can be problematic. For example, the first scenario discussed above provides a disjointed experience for the user. The user browses (i.e., with a browser application) media service Web pages in search of desired content, and then purchases and downloads the content. To use the content (e.g., play, bum to CD, transfer to portable player, etc.) the user must then initiate a separate action through a media player application. Thus, the experience is a disjointed and sometimes time consuming combination of steps that necessitates the use of different applications.
In the second scenario discussed above, the user is limited to media content that is made available through the media player application, as well as being limited to the presentation of that content as dictated by the media player application. The variety of content accessible to the user is therefore limited to content secured by the media player through agreements with various media services. A user who desires a wider variety of media content may not be able to find the content they want through the media player, and thus be relegated to using a browser application to search for their desired content in the same type of disjointed experience as discussed above.
Accordingly, from an end-user perspective, a need exists for a way to provide an uninterrupted media experience that includes the discovery, acquisition, and use of a variety of media content within a feature rich player environment specifically, and within an overall operating system environment more generally. From a media services perspective, a corresponding need exists for a way to enable media services to have control over the way users discover and acquire media for use within a feature rich player environment and/or an overall operating system environment.
SUMMARY
A graphical user interface allows users to access multiple third party services (e.g., online media services) and enables the services to provide functionality within the GUI adjacent to core functionality of a host application (e.g., a media player application, operating system shell, etc.) in a cohesive manner. The GUI provides an interface region for third party service functionality that is distinct from, but equal in exposure and prominence to, the core functionality provided by the application hosting the GUI. The GUI enables seamless switching between a list of available services provided in a service menu. Switching between services replaces service function buttons and service branding according to particular service customizations.

DETAILED DESCRIPTION
Introduction
The following discussion is directed to a graphical user interface system and methods that enable switching between a plurality of online media services from within a host application, such as a PC-based media player application. A user can switch to any one of a number of online services made available in a services menu and thereby make that service the active service. In addition, the currently active online service is given customization opportunities that permit the active service to customize regions of the GUI in a host media player application or other application and/or operating system (e.g., active service provides a service information file that includes URLs to Web pages of the active service). Advantages of the described system and methods include providing online media services with an ability to control the way in which customers discover and purchase media from within the feature rich environment of various user applications such as a PC-based media player application. From a user's perspective, the advantages include an uninterrupted media experience that can involve the entire process of discovering, purchasing and using a wide variety of media content all from within the feature rich environment of a media player application.
Exemplary Service Switching and Customization Environment
FIG. 1 illustrates an exemplary system environment 100 suitable for enabling switching between various online media services and allowing an active service to customize portions of an application on a computer 102. The exemplary environment 100 includes computer 102 operatively coupled to a plurality of online services 104 and a Web listing service 106 via a network 108. Network 108 can include both local and remote connections depending on the particular system configuration. Thus, network 108 may include, for example, any one or a combination of a modem, a cable modem, a LAN (local area network), a WAN (wide area network), an intranet, the Internet, or any other suitable communication link.
Computer 102 is typically implemented as a user's primary computing device, such as a desktop personal computer (PC). Computer 102 might also be implemented as other conventional computing devices generally configured to receive and render multi-media content (e.g., play back, burn to CD, transfer to portable playback device, etc.) from various online media services. An exemplary implementation of a computer 102 is depicted in FIG. 12 and described in greater detail below in the Exemplary Computing Environment section.
Online services 104 and Web listing service 106 are typically implemented as one or more server computers such as a Web server. Thus, online services 104 and Web listing service 106 may include a variety of general purpose computing devices such as workstation computers, and may be configured in a manner similar to an exemplary implementation of computer 102 such as described below in the Exemplary Computing Environment referring to FIG. 12. Online services 104 and Web listing service 106 generally provide storage for electronic documents and information including multi-media content that is accessible to client computers such as computer 102 over network 108.
Exemplary Embodiments
FIG. 2 illustrates a block diagram representation of an exemplary computer 102 that is suitable for enabling switching between various online media services 104 and allowing an active service to customize portions of an application on a computer 102. Various components on computer 102 facilitate the retrieval and management of media content for the general purpose of rendering the content on computer 102 and/or synchronizing the content with a portable playback device. These components include, for example, an operating system 200 and its sub-components (e.g., the operating system's folder system application, or “Shell” 202), various applications 204 such as, specifically, a media player 206, a media library 208 (i.e., a database that contains digital media files), and a service switching and customization architecture 210. Although these components are illustrated separately on computer 102, it is noted that any one or more of these components may be implemented on computer 102 as part of a multimedia software product, the operating system 200, stand-alone components, and so on.
An application 204 may be any of various applications and/or tools configured to perform various computing tasks such as emailing, word processing, financial analysis, and so on. An application 204 may also be an application or tool configured to receive and manipulate media content, such as from an online media service 104 or some other source. For example, application 204 may be an interactive TV service application that facilitates the recording of video (e.g., TV programming) directly off of a cable and/or satellite feed, a video capture component to transfer home video footage from a digital video recorder onto computer 102, a Web browser application that facilitates downloading media over a network 108, and so on. Thus, applications 204 may supply various forms of media content to a media library 208 on computer 102. Media content stored in media library 208 may include, for example, audio files in the form of MP3 and WMA files, video files in the form of AVI and MOV files, and image files in the form of GIF and JPEG files, and so on.
A specific example of an application 204 that is illustrated in FIG. 2 is a media player application 206. A media player application 206 is typically a desktop based media player that manages a broad range of multimedia related tasks regarding the discovery, acquisition and use of media content. For example, a media player application 206 may handle streaming audio and video, CD/DVD playback, MP3 and WMA support, encoding, CD/DVD burning, transferring media to a portable playback device, Internet radio, and the like. Like some other applications 204, a media player application 206 supplies various forms of media content (e.g., audio files, video files, image files, etc.) to media library 208 on computer 102. Although the media player application 206 and media library 208 are illustrated in FIG. 2 and discussed herein as separate components on computer 102, in other embodiments they may just as readily be a part of the operating system 200 itself.
A service switching and customization architecture 210 is configured to be operatively interactive with any one or more of the components of computer 102 noted above for the general purpose of enabling switching between various online media services 104 and allowing an active service to customize portions of such components on computer 102. Thus, one or more applications 204 and/or components of computer 102 (e.g., operating system 200, shell 202) may “host” the service switching and customization architecture 210. For example, in one embodiment, the service switching and customization architecture 210 may be an integral component of, and/or operatively interactive with, the media player application 206. Accordingly, although the current embodiment of the service switching and customization architecture 210 will be discussed herein with specific reference to the media player application 206 as a host application, various aspects of service switching and customization may be hosted by and/or be generally applicable in similar ways to various components of computer 102 including, for example, the operating system 200 and its sub-components (e.g., shell 202), and various other applications 204.
The service switching and customization architecture 210 includes an online service manager component 212, an all-services file 214, and a number of service information files 216. The online service manager 212 is generally configured to populate a service menu list within the media player 206, and to manage switching between online services and to manage customizations made to the player that are provided by a currently active service. Each time computer 102 is connected to the network 108, the online service manager 212 fetches the all-services file 214 from a Web service listing 106. In the current embodiment, the all-services file 214 is an XML (Extended Markup Language) file that is kept up-to-date on the Web service listing 106 so that the online service manager 212 always has access to the latest list of valid online services 104. The all-services file 214 includes a list of all valid online services 104 and any other information needed to populate a service menu list within the media player 206. As discussed in more detail below, the online service manager 212 uses information in the all-services file 214 to determine where to retrieve a service information file 216 for each of the valid services identified in the all-services file 214.
When a valid all-services file 214 is retrieved from Web service listing 106, the service manager 212 populates the service menu list within the media player 206 with the list of valid online services from the file. Prior to a new selection being made by a user from the service menu list, the last active service is present in all the customization points within the media player 206.
In general, a UI manager 218 component of the service switching and customization architecture 210 manages the display of a graphical user interface (GUI) on a computer display device. The UI manager 218 manages the GUI in conjunction with online service manager 212 and user input instructions entered through a user interface selection device (e.g. a mouse) that controls motions and selections of a pointer displayed on the GUI. Although the UI manager 218 is illustrated in FIG. 2 as being part of the online service manager 212, this is for illustrative purposes only and is not intended to be limiting. Thus, the UI manager 218 may be configured differently, such as being a stand-alone component or a part of another component on computer 102.
FIGS. 3a-3d illustrate examples of such a GUI in the form of a command bar user interface. The command bar user interface provides access to functionality for both a host application (e.g., a media player application) and a currently active media service being hosted by the host application. The command bar user interface enables switching between a plurality of online media services from within a host application. Users can switch to any one of a number of online services made available by the command bar through a service list menu. A selected online service becomes the currently active service. The currently active online service is given customization opportunities that permit customization of different areas of the user interface within the host application.
Referring to FIG. 3a, the command bar user interface illustrates two regions or areas in which function buttons are displayed. A “host application function area” includes application function buttons C1-C5 that are intended to illustrate functions of the host application that a user can activate through the user interface. For example, if the host application is a media player application, some of the functions represented by C1-C5 might include a function for burning music onto a CD or a function for synchronizing content with a mobile device. Furthermore, any of the buttons C1-C5 could themselves be menus offering additional functionality related to the particular button. The number of application function buttons and the manner in which they are illustrated is shown in FIGS. 3a-3d by way of example only, and is not intended to be limiting. Thus, certain applications may have a greater or lesser number of application function buttons displayed in the host application function area of the command bar user interface. Note that in practice, the application function buttons may not have superscript numbers designating their functions. Rather, an application function associated with an application function button will likely be designated with a text description or a graphical representation (e.g., an icon or animation) that indicates the function.
Another region of the command bar user interface is the “service function area”. The service function area includes service function buttons S1-1-S1-3 that are intended to illustrate functions provided by a currently active online media service and are made accessible to a user through the user interface. The service function area also includes a “Service Brand” icon and a “Service Menu” button. The superscript numbers on the service function buttons indicate that a particular online service is the currently active service and that a number of functions are available for that service. For example, service function button S1-1 is intended to designate a first function for the currently active online media service number 1, indicated by the “Service 1 Brand” icon. Likewise, service function button S1-3 indicates a third function for the currently active online service number 1. Note that in practice, the service function buttons may not have superscript numbers designating their functions and a particular service. Rather, service function buttons will likely be designated with a text description that indicates their function, and the currently active service may be identified by the “Service Brand” icon shown in the service function area (e.g., “Service 1 Brand”). The “Service Menu” button facilitates access to a list of valid online services as discussed more below with reference to FIG. 3c. 
Referring still to FIG. 3a, the command bar user interface illustrates in the “host application function area” that a host application function has been activated by a user through the selection of application function button C2. When an application function button is active, the command bar user interface typically alters the appearance of the button to indicate its active state as shown in FIG. 3a. The change in appearance can be implemented in a variety of ways including, for example, by highlighting the application button, changing the color of the application button, adjusting the texture of the application button, and adjusting a background intensity level of the application button.
FIG. 3b illustrates that a user has selected a service function button S1-1 from the “service function area”. Thus, the user intends to implement the function associated with the S1-1 service button which, as noted above, corresponds to the currently active online service designated by the “Service 1 Brand”. As illustrated in FIG. 3b, when a service function button is selected by a user, it becomes active. The service button's active state is indicated by a change in appearance to the button. Furthermore, when an online service function is activated, the command bar interface also changes or shifts the appearance of the “Service Function Area” to indicate the active state of the online service function to the user. Thus, FIG. 3b illustrates a change in the appearance to both the service function button S1-1 and to the service function area. The change in appearance to a service function button and the service function area can be implemented in a variety of ways including, for example, by highlighting them, changing their colors, adjusting their textures, and adjusting their background intensity levels.
FIG. 3c illustrates use of the “Service Menu” to switch the currently active online service to a different online service. As noted in FIG. 3c, the service menu has been selected. Selection of the service menu can be indicated by a change in appearance to the service menu button, similar to that just discussed above. When the service menu is selected, a list of valid online media services appears in a drop-down menu box. A user then has the opportunity to switch the currently active online service to a different online service based on the available services within the list of valid services.
FIG. 3d illustrates the result of a selection made from the list of valid online media services appearing in the drop-down menu box of FIG. 3c. The selection the user made was “Service 2”, which is indicated by the “Service 2 Brand” icon now appearing in the service function area. In addition, the service function buttons changed to correspond with the newly active online service selected by the user. Furthermore, although not illustrated in FIG. 3d, the appearance of the service function area may also change according to customizations provided by the newly active online service indicated by the “Service 2 Brand” icon.
FIGS. 4-7 illustrate more specific examples of how the command bar user interface described with reference to FIGS. 3a-3d might be implemented with respect to the graphical user interface of a media player 206 application. FIG. 4 illustrates an example user interface for media player 206 as it might appear on a display of computer 102. Assuming an all-services file 214 has just been retrieved, customization points such as the menu task pane 400 and the service function button area 402 in the top level command bar are still controlled by the last active service. Thus, the current service menu task pane 400 displays the HTML page associated with the last active service, which in the FIG. 4 example is “Movielink”, as indicated in the service function area 402 of the command bar by the “Movielink” brand icon.
A selection arrow is shown in FIG. 4 hovering over a service list menu button 404 in the command bar. When a user “selects” the service list menu button 404 using a user interface selection device (e.g., a mouse), a drop-down box will open up and reveal the list of valid online services from the all-services file 214. FIG. 5 illustrates an example of a list of valid online services 500 appearing in the drop-down box 502 after the service list menu button 404 has been “clicked” by a user. From the list of valid online services 500, a user can select an online service to be the currently active service. Only one service can be the active service at any one time, and the active service controls all of the customization opportunities within the media player 206, such as the service menu task pane 400, which in FIGS. 4 and 5 is controlled by the currently active “Movielink” service. Thus, a user is able to switch between the different online services 500 shown in the services drop-down box 502 and thereby change which service controls the customization points in the media player 206.
FIG. 6 illustrates a selection of an online service being made that will switch the active service from the “Movielink” online service to the “Music Box” online service. Switching between these services will shift control of the customization points within media player 206 from the “Movielink” service to the “Music Box” service. As shown in FIG. 6, the “Music Box” online service has been highlighted 600 for selection. FIG. 7 illustrates the newly selected “Music Box” service as the active service. Accordingly, customization points within the media player 206 have changed according to the new active “Music Box” service and the background under the active service buttons has changed. In FIG. 7, the apparent customization points that have changed are the text and icon in the service function button area 402 and the HTML page in the service menu task pane 400. It is noted that the customization points discussed thus far are only examples of customization points, and that various other customization points also exist, some of which are discussed in greater detail below. For example, the several service function buttons 700 are customization points whose color and text descriptions can be customized by the currently active service.
FIG. 8 illustrates an example of an all-services file 214. As noted above, the all-services file 214 is an XML (Extended Markup Language) file that contains a list of valid online services and other information needed to populate a service menu list within the media player 206. Other important information included in the all-services file 214 is a URL (universal resource locator) link to a service information file 216 for each of the services listed in the all-services file 214. When a service is selected from the service menu list within the media player 206, the URL for the selected service is accessed and the service information file 216 for that service is retrieved.
Referring to FIG. 8, an all-services XML file 214 includes various elements that tell the media player 206 how to populate the initial service menu list and where to retrieve each service information file 216. These elements include <services>, <default>, <browse>, <service>, <friendlyname>, and <image> elements. The <services> element includes an optional version attribute that indicates the version of the XML file. The <default> element includes a required key attribute that is used to set the initial default service in the player on the very first use of the player. The <browse> element includes a required URL attribute that links to a “browse all services” page that matches the services that are listed in the all-services file 214. Selecting a “Browse All Services . . . ” menu item will open the <servicetask1> (discussed below) and switch to a page that will list and promote partner online services. The <service> elements represent each service that is a valid service. Each <service> element includes a required key attribute that is a service key representing the service, a required XMLURL attribute that is a fully qualified URL to the service's service information file 216, an optional position attribute that indicates the initial position of the service in the service menu list, and an optional type attribute that represents whether the service can customize all customization points within the media player 206 or just the service panes within the media player 206. The <friendlyname> element includes optional text that represents the name that is shown to the user for the service. If the <friendlyname> element is not specified, the <service> key attribute is used in the player 206 wherever the <friendlyname> element is needed. The <image> element includes an optional MenuURL attribute that is a fully qualified URL to a graphic image to use on the service menu list.
As noted above, when a service is selected from the service menu list within the media player 206, the URL for the selected service is accessed and the service information file 216 for that service is retrieved. Like the all-services file 214 discussed above, the service information file 216 is preferably an XML file. Each valid online service in the all-services file 214 hosts it own service information file 216 and uses this file to manage the customization opportunities within the media player 206. Customization opportunities, or customization points, are places or areas within the media player 206 GUI (e.g., service area of command bar, task panes, etc.) that the media player gives up control over so that the active service can customize them to its own preference. Three main categories of customization can generally be described as music, video (TV, movie), and radio. Referring to FIG. 7, these categories are represented by the three service function buttons 700, whose color and text descriptions can be customized by the currently active service.
An active/selected service provides an HTML page for display in task pane 400 for one or more service function buttons 700. The HTML page typically provides access to a purchase experience. For example, an active music service may provide an HTML page that permits a user to search for a particular song or CD, after which the user can purchase and download the song or CD. A service can choose to include one or all of the three categories depending on the type of service. For example, a video service that offers only video products may only choose to use and customize the video category task tab and forego using the music and radio tabs.
In addition to the three main service function buttons 700, an active service also controls customization points regarding various media player functions (i.e., host application functions), such as those represented by the application function buttons 702 on the left side of the media player command bar shown in FIG. 7. For example, the “Now Playing” function button displays videos in the task pane 400 when a video is being played on the media player 206. However, when only audio (e.g., music) is playing on the media player, the “Now Playing” function displays either visualizations (i.e., shapes, animations, etc.) or an InfoCenter view. The InfoCenter view is an HTML page provided by the active service that typically includes useful information regarding the music that is being played by the media player at the time, such as track listings, artists, etc. Furthermore, the “Now Playing” function includes a “Buy Media” (e.g., “Buy CD”, “Buy Video”) shortcut link to the corresponding service function button 700 that permits a user to directly initiate a purchase experience regarding the currently playing media. Typically, the shortcut link will bypass intermediate steps such as searches, and proceed directly to a page that permits purchasing the media currently playing on the media player 206.
In addition to the “Now Playing” function as a customization opportunity for the currently active service, various other functions provide such customization opportunities within media player 206. FIG. 9 illustrates an example of a service information file 216 which includes examples of the various types of functions providing customization opportunities. Each service information file 216 includes various elements that tell the media player 206 how to customize the customization points within the player. These elements include <serviceinfo>, <friendlyname>, <image>, <color>, <servicetask1>, <servicetask2>, <servicetask3>, <infocenter>, <albuminfo>, <buycd>, <install>, and <htmlview> elements.
The <serviceinfo> element is required, and is the container element for the service information file 216. The <serviceinfo> element includes an optional version attribute that indicates the version of the XML file, and a required key attribute that is used by the media player 206 to uniquely identify the particular service. The <friendlyname> element is a required element that includes text that will be used to represent the name of the service on the service menu list in the media player 206. The <image> element is optional and it represents the graphical images that should be used to represent the service. The <Image> element includes an optional MenuURL attribute that is a fully qualified URL to a 16×16 graphic image to use on the service menu list, an optional ServiceSmallURL that is a fully qualified URL to a 30×30 graphic image to use in the chrome, and an optional ServiceLargeURL that is a fully qualified URL to a 30×60 graphic image to use in the chrome. The file formats supported include .gif, .jpg, .bmp, and .png. PNG is the preferred file format as transparency is also supported and recommended. If the MenuURL attribute isn't specified, then no graphic is used on the menu. The ServiceLargeURL attribute for the chrome service image is used if both ServiceSmallURL and ServiceLargeURL are present. If the chrome images are wider than the image area (30 or 60 depending on which element), then the image area is animated over the image area when the user selects the service.
The <color> element is optional and is used to specify the service area button color and navigation bar color. The <color> element includes a required mediaplayer attribute of hex RGB value (#FFDDCC). The <servicetask1>, <servicetask2>, and <servicetask3> elements represent the three service function buttons 700 (FIG. 7) in the service function area of the command bar. The <servicetask1> element is required, while <servicetask2> and <servicetask3> are optional. Each of the 3 elements includes a required URL attribute that is a fully qualified URL to an HTML page that will be loaded to the respective task pane when the user switches services and selects that pane, a required <buttontext> attribute that includes text that will be used as the button text for the task pane, and an optional <buffontip> attribute that includes text that will be displayed when the user hovers over the button for the task pane. The <servicetask1> element is required and is considered the primary commerce pane. The media player will launch into this pane when the user selects “Buy Media” within the player. As noted above, the three main categories of customization for these elements can generally be described as music, video (TV, movie), and radio.
The <infocenter> element is optional and is used to specify a customization of the “Now Playing” InfoCenter view. The <infocenter> element includes a required URL attribute that is a fully qualified URL that refers to an HTML page. As noted above, the <infocenter> view HTML page provided by the active service typically includes useful information regarding the music that is currently being played by the media player, such as track listings, artists, etc. The <albuminfo> element is an optional element that is used to specify a customization of the album information windows in the Burn to CD and Media Library panes.

Exemplary Methods
Example methods for enabling switching between various online media services and allowing an active service to customize portions of an application on a computer through a command bar user interface will now be described with primary reference to the flow diagrams of FIGS. 10 and 11. The methods apply to the exemplary embodiments discussed above with respect to FIGS. 1-9. While one or more methods are disclosed by means of flow diagrams and text associated with the blocks of the flow diagrams, it is to be understood that the elements of the described methods do not necessarily have to be performed in the order in which they are presented, and that alternative orders may result in similar advantages. Furthermore, the methods are not exclusive and can be performed alone or in combination with one another. The elements of the described methods may be performed by any appropriate means including, for example, by hardware logic blocks on an ASIC or by the execution of processor-readable instructions defined on a processor-readable medium.
A “processor-readable medium,” as used herein, can be any means that can contain, store, communicate, propagate, or transport instructions for use or execution by a processor. A processor-readable medium can be, without limitation, an electronic, magnetic, optical, electromagnetic, infrared, or semiconductor system, apparatus, device, or propagation medium. More specific examples of a processor-readable medium include, among others, an electrical connection (electronic) having one or more wires, a portable computer diskette (magnetic), a random access memory (RAM) (magnetic), a read-only memory (ROM) (magnetic), an erasable programmable-read-only memory (EPROM or Flash memory), an optical fiber (optical), a rewritable compact disc (CD-RW) (optical), and a portable compact disc read-only memory (CDROM) (optical).
Referring to FIG. 10, at block 1002 of method 1000, a list of online services is retrieved. An online service manager 212 related to an application 204 (e.g., a media player 206) executing on a computer, goes online via a network and accesses a Web listing service. The online service manager 212 retrieves an all-services XML file containing a list of valid online services and additional information. One skilled in the art will readily recognize other ways in which a list of valid online services may be retrieved. For example, the list could be hardcoded on the computer by the OEM and then retrieved by the online service manager 212. The list could also be manually constructed by a user registering a media player for a Web protocol such that when the user clicks on a special link in the Web page of a service provider, the link is received by the player and the service is added to the service list. Thus, other sources may be readily available from which the online service manager 212 can access the list of valid online services.
At block 1004, an online service is set as an initial active service based on the last active service previously chosen by the user. If the application has never run before, a default service specified by the all-services file is initially set as the active service.
At block 1006, the online service manager 212 enables the selection of one of the online services as an active service. A service menu within a media player 206, for example, is populated with the list of online services. Each online service is represented in the service menu with a friendly and a graphical image if the name and image have been included by the active service in the retrieved list of online services. Selection of one of the online services includes accepting user input that identifies which online service the user desires to make the current active service within the media player.
At block 1008, customization points within the media player 206 (or other application 204, operating system 200, etc.) are customized based on the active service. Customization includes retrieving a service information file from the active service and customizing the customization points within the media player 206 (and/or operating system shell 202 and applications 204) by enabling the active service, via the service information file, to control the content within the customization points. The customization points include, for example, task panes and task pane buttons within the media player. Customizations within a media player 206 (and/or operating system shell 202 and applications 204) can include a variety of content input and modifications made to parts of the software, including for example, identifying a name for service function button using text provided by the active service, displaying button tip text for the service function button when a selection tool hovers over the service function button, the button tip text being provided by the active service, displaying (in a task pane) an HTML page specified by the active service when a user selects the service function button. Customizations can also include displaying an HTML page from the active service within a Now Playing function button of the media player, where the HTML page provides an InfoCenter view that includes information related to music that is currently being played by the media player. Customizations can also include displaying an HTML page from the active service, where the HTML page provides album information in a burn-to-CD (compact disc) task pane and a Media Library task pane. Customizing can also include displaying a “Buy CD” link to a Web page of the active service within a Now Playing task pane, where the Web page permits purchasing the CD (compact disc) or DVD (digital video disc) that is currently playing on the media player.
At block 1010, a user input selection is received through the service menu for a different service from the available online services. At block 1012, the online service manager 212 retrieves a service information file for the different service. At block 1014, the online service manager 212 switches the active service to the different service based on the input selection made by the user.
Referring to FIG. 11, at block 1102 of method 1100, a user interface is displayed. The user interface includes a command bar that has a host application region to control functions of a host application (e.g., a media player application), and a service region to control functions of a currently active service provider. The application region includes application buttons to control functions of the application and the service region includes service buttons to control functions of the currently active media service.
At block 1104, the user interface provides access to a list of services through a service list menu. User input is received through a user interface selection device (e.g., a mouse) indicating the selection of a service list menu button in the service region. The service list menu provides a drop-down box to display a list of valid services.
At block 1106, the user interface enables a switch from the currently active service to a newly active service. User input is received via the user interface selection device indicating a particular service has been selected from service list menu. In response to the user selection, the active service is switched from the currently active service to the particular/selected service, making it the newly active service. In addition, the appearance of the service region and service buttons within the service region is altered in accordance with customizations provided by the newly active service. For example, the service region branding icon is changed from one identifying the currently active service to one identifying the newly active service.
At block 1108, the appearance of the service region is altered when a service function is made active (e.g., by user input selection of the service function button). Alterations in appearance can include, for example, highlighting, changes in color, adjustments in texture, and adjust of background intensity of the service region.
