     BACKGROUND 
     The Internet has seen expansive growth over the last several years. Not only are there more Web sites providing a wide range of information, service, and goods, there are more users on the Internet than ever before. 
     Today, users may experience multimedia clips, purchase goods, access the world&#39;s news as it happens, obtain reviews on various items or products in a variety of formats, or access a variety of resources all on the Internet. For example, a user may read product reviews, view pictures of a product, or in some instances, watch a video presentation related to the product. 
     In order to access the available resources, however, Internet users are exposed to a variety of different media types while visiting a Web site. Not only may users access textual information, they may also view graphical images, or watch multimedia presentations, including audio and video, that may be streamed or downloaded. The steps required to access this media, however, may be overwhelming to many of the users. Not only do certain sites require users to use particular products to access the media, many sites require the user to know the configuration of their system in order to play certain media files. For example, a user may have to download a particular media player, upgrade to a different version, or know the particular programs they are using on their system. With so many available options to access and play media files, users are constantly bombarded with different requirements. 
     Another requirement to view many multimedia sites is a high bandwidth connection to the Internet. Many sites rely on the user having a high bandwidth when streaming media to the user. While the majority of businesses today have access to broadband, the majority of home users connect to the Internet through a low speed dial-up modem resulting in a poor multimedia experience. 
     SUMMARY 
     Methods and systems for providing rich media presentations to a network device are discussed herein. 
     According to one embodiment, virtual player packages are delivered to a device over a network. The virtual player packages are delivered to the requesting device in an optimized manner. 
     According to another embodiment, attributes of the device are determined. The attributes may include information relating to the operating system of the device; a preferred media player; a bandwidth parameter; presence or absence of a firewall, permissions related to the requesting device, and the like. 
     According to yet another embodiment, rich media presentations, including a virtual player, presentation packages, and media packages, are provided to the requesting device. The creation of the rich media presentations is partly based on the determined attributes and is directed at being optimized for the requesting device. 
     According to still yet another embodiment, the rich media presentations may be delivered to the device before a request is made by the device to play the presentation. 
     According to still yet another embodiment, the rich media presentations are retrieved from a location on the network that is directed at providing optimized throughput to the requesting device. When the rich media presentations are cached at the location on the network, the rich media presentations are delivered to the device. Otherwise, the appropriate rich media presentations are created for the device, and the rich media presentations are cached for future delivery. Alternatively, the rich media presentations may be generated in real-time and delivered.

     Illustrative Operating Environment 
     With reference to  FIG. 1 , an example system includes wireless mobile devices  105 - 108 , wireless network  110 , gateway  115 , one or more content delivery networks (CDN)  120 , wide area network (WAN)/local area network (LAN)  200 , one or more network devices  130 , and one or more world wide web (WWW) origin servers  300 . 
     Wireless devices  105 - 108 , are coupled to wireless network  110  and are described in more detail in conjunction with  FIG. 4 . Generally, mobile devices  105 - 108  include any device capable of connecting to a wireless network such as wireless network  110 . Such devices include cellular telephones, smart phones, pagers, radio frequency (RF) devices, infrared (IR) devices, citizen band radios (CBs), integrated devices combining one or more of the preceding devices, and the like. Mobile devices  105 - 108  may also include other devices that have a wireless interface such as PDAs, handheld computers, personal computers, multiprocessor systems, microprocessor-based or programmable consumer electronics, network PCs, wearable computers, and the like. 
     Wireless network  110  transports information to and from devices capable of wireless communication, such as mobile devices  105 - 108 . Wireless network  110  may include both wireless and wired components. For example, wireless network  110  may include a cellular tower linked to a wired telephone network. Typically, the cellular tower carries communication to and from cell phones, pagers, and other wireless devices, and the wired telephone network carries communication to regular phones, long-distance communication links, and the like. 
     Wireless network  110  is coupled to WAN/LAN through gateway  115 . Gateway  115  routes information between wireless network  110  and WAN/LAN  200 . For example, a user using a wireless device may browse the Internet by calling a certain number or tuning to a particular frequency. Upon receipt of the number, wireless network  110  is configured to pass information between the wireless device and gateway  115 . Gateway  115  may translate requests for web pages from wireless devices to hypertext transfer protocol (HTTP) messages, which may then be sent to WAN/LAN  200 . Gateway  115  may then translate responses to such messages into a form compatible with the requesting device. Gateway  115  may also transform other messages sent from wireless devices  105 - 108  into information suitable for WAN/LAN  200 , such as e-mail, audio, voice communication, contact databases, calendars, appointments, and the like. 
     Typically, WAN/LAN  200  transmits information between computing devices as described in more detail in conjunction with  FIG. 2 . One example of a WAN is the Internet, which connects millions of computers over a host of gateways, routers, switches, hubs, and the like. An example of a LAN is a network used to connect computers in a single office. A WAN may connect multiple LANs. 
     Content delivery network (CDN)  120  is coupled to WAN/LAN  200  through communication mediums. CDN  120  may include many types of CDNs. For example, CDN  120  may include audio/video CDNs  122  designed to optimally deliver audio and video or script/data CDNs  124  designed to optimally deliver script or data to the requesting device. CDNs use various techniques to improve the performance of content delivery for Web sites. They may increase reliability of a web site by providing mirrored content across distributed servers and provide increased bandwidth as compared to a single server. CDNs may also employ various caching techniques to increase the end user&#39;s performance. Content may be pushed to the edges of the network to minimize delay associated with retrieving the content. Load balancing may also be used to help route a user&#39;s request for content to the best available content source. Typically, a web site subscribes to a CDN and instructs the CDN how to deliver its content. The subscribing web site may serve some content on its own avoiding the CDN and use the CDN to serve other content. While CDNs are typically used for WAN/LAN applications, the technology may be applied to intranets and extranets as well. 
     WWW origin servers  300  are coupled to WAN/LAN  200  through communication mediums. WWW origin servers  300  provide access to information and services as described in more detail in conjunction with  FIG. 3 . 
     Network device  130  is coupled to WAN/LAN  200  and is described in more detail in conjunction with  FIG. 4 . Generally, network device  130  includes any device capable of connecting to a data network, and includes the functionality to play media included in a media playlist. 
       FIG. 2  shows another example system in which a number of local area networks (“LANs”)  220   a-d  and wide area networks (“WANs”)  230  are interconnected by routers  210 . Routers  210  are intermediary devices on a communications network that expedite message delivery. On a single network linking many computers through a mesh of possible connections, a router receives transmitted messages and forwards them to their correct destinations over available routes. On an interconnected set of LANs, including those based on differing architectures and protocols, a router acts as a link between LANs, enabling messages to be sent from one to another. Communication links within LANs typically include twisted wire pair, fiber optics, or coaxial cable, while communication links between networks may utilize analog telephone lines, full or fractional dedicated digital lines including T 1 , T 2 , T 3 , and T 4 , Integrated Services Digital Networks (ISDNs), Digital Subscriber Lines (DSLs), wireless links, or other communications links known to those skilled in the art. Furthermore, computers, such as remote computer  240 , and other related electronic devices can be remotely connected to either LANs  220   a-d  or WAN  230  via a modem and temporary telephone link. The number of WANs, LANs, and routers in  FIG. 2  may be increased or decreased without departing from the spirit or scope of the describe embodiments. As such, it will be appreciated that the Internet itself may be formed from a vast number of such interconnected networks, computers, and routers and that an embodiment could be practiced over the Internet without departing from the spirit and scope of this disclosure. 
     The media used to transmit information in communication links as described above illustrates one type of computer-readable media, namely communication media. Generally, computer-readable media includes any media that can be accessed by a computing device. Computer-readable media may include computer storage media, communication media, or any combination thereof. 
     Communication media typically embodies computer-readable instructions, data structures, program modules, or other data in a modulated data signal such as a carrier wave or other transport mechanism and includes any information delivery media. The term “modulated data signal” means a signal that has one or more of its characteristics set or changed in such a manner as to encode information in the signal. By way of example, communication media includes wired media such as twisted pair, coaxial cable, fiber optics, wave guides, and other wired media and wireless media such as acoustic, RF, infrared, and other wireless media. 
     The Internet has recently seen explosive growth by virtue of its ability to link computers located throughout the world. As the Internet has grown, so has the WWW. Generally, the WWW is the total set of interlinked hypertext documents residing on HTTP servers around the world. Documents on the WWW, called pages or Web pages, are typically written in HTML (Hypertext Markup Language) or some other markup language, identified by URLs (Uniform Resource Locators) that specify the particular machine and pathname by which a file can be accessed, and transmitted from server to end user using HTTP. Codes, called tags, embedded in an HTML document associate particular words and images in the document with URLs so that a user can access another file, which may literally be halfway around the world, at the press of a key or the click of a mouse. These files may contain text (in a variety of fonts and styles), graphics images, movie files, media clips, and sounds as well as Java applets, ActiveX controls, or other embedded software programs that execute when the user activates them. A user visiting a Web page also may be able to download files from an FTP site and send messages to other users via email by using links on the Web page. 
     A WWW origin server, as described in more detail in conjunction with  FIG. 3 , is a computer connected to the Internet having storage facilities for storing hypertext documents for a WWW site and running administrative software for handling requests for the stored hypertext documents. A hypertext document normally includes a number of hyperlinks, i.e., highlighted portions of text which link the document to another hypertext document possibly stored at a WWW site elsewhere on the Internet. Each hyperlink is associated with a URL that provides the location of the linked document on a server connected to the Internet and describes the document. Thus, whenever a hypertext document is retrieved from any WWW origin server, the document is considered to be retrieved from the WWW. As is known to those skilled in the art, a WWW origin server may also include facilities for storing and transmitting application programs, such as application programs written in the JAVA programming language from Sun Microsystems, for execution on a remote computer. Likewise, a WWW origin server may also include facilities for executing scripts and other application programs on the WWW origin server itself. 
     A user may retrieve hypertext documents from the WWW via a WWW browser application program located on a wired or wireless device. A WWW browser, such as Netscape&#39;s NAVIGATOR® or Microsoft&#39;s INTERNET EXPLORER®, is a software application program for providing a graphical user interface to the WWW. Upon request from the user via the WWW browser, the WWW browser accesses and retrieves the desired hypertext document from the appropriate WWW origin server using the URL for the document and HTTP. HTTP is a higher-level protocol than TCP/IP and is designed specifically for the requirements of the WWW. HTTP is used to carry requests from a browser to a Web server and to transport pages from Web servers back to the requesting browser or client. The WWW browser may also retrieve application programs from the WWW origin server, such as JAVA applets, for execution on a client computer. 
       FIG. 3  shows an example WWW origin server  300  that is operative to provide a WWW site. Accordingly, WWW origin server  300  transmits WWW pages to the WWW browser application program executing on requesting devices to carry out this process. For instance, WWW origin server  300  may transmit pages and forms for receiving information about a user, such as user preferences, address, telephone number, billing information, credit card numbers, and the like. Moreover, WWW origin server  300  may transmit WWW pages to a requesting device that allow a user to participate in a WWW site. The transactions may take place over the Internet, WAN/LAN  200 , or some other communications network known to those skilled in the art. 
     WWW origin server  300  may include many more components than those shown in  FIG. 3 . However, the components shown are sufficient to disclose an example embodiment. As shown in  FIG. 3 , WWW origin server  300  is connected to WAN/LAN  200 , or other communications network, via network interface unit  310 . Network interface unit  310  includes the necessary circuitry for connecting WWW origin server  300  to WAN/LAN  200 , and is constructed for use with various communication protocols including the TCP/IP protocol. Typically, network interface unit  310  is a card contained within WWW origin server  300 . 
     WWW origin server  300  also includes processing unit  312 , video display adapter  314 , and a mass memory, all connected via bus  322 . The mass memory generally includes RAM  316 , ROM  332 , and one or more permanent mass storage devices, such as hard disk drive  338 , a tape drive, CD-ROM/DVD-ROM drive  326 , and/or a floppy disk drive. The mass memory stores operating system  320  for controlling the operation of WWW origin server  300 . This component may comprise a general purpose server operating system, such as UNIX, LINUX™, Microsoft WINDOWS NT®, and the like. Basic input/output system (“BIOS”)  318  is also provided for controlling the low-level operation of WWW origin server  300 . 
     The mass memory as described above illustrates another type of computer-readable media, namely computer storage media. Computer storage media may include volatile and nonvolatile, removable and non-removable media implemented in any method or technology for storage of information, such as computer readable instructions, data structures, program modules or other data. Examples of computer storage media include RAM, ROM, EEPROM, flash memory or other memory technology, CD-ROM, digital versatile disks (DVD) or other optical storage, magnetic cassettes, magnetic tape, magnetic disk storage or other magnetic storage devices, or any other medium which can be used to store the desired information and which can be accessed by a computing device. 
     The mass memory also stores program code and data for providing a WWW site. More specifically, the mass memory stores applications including WWW server application program  330 , programs  334 , and rich media presentation application  336 . Generally, rich media presentation application  336  generates and provides rich media presentations to a requesting network device (See FIGURES and related discussion below). WWW server application program  330  includes computer executable instructions which, when executed by WWW origin server  300 , generate WWW browser displays, including performing the logic described above. WWW origin server  300  may include a JAVA virtual machine, an SMTP handler application for transmitting and receiving email, an HTTP handler application for receiving and handing HTTP requests, JAVA applets for transmission to a WWW browser executing on a client computer, and an HTTPS handler application for handling secure connections. The HTTPS handler application may be used for communication with external security applications (not shown), to send and receive private information in a secure fashion. 
     WWW origin server  300  may also comprise input/output interface  324  for communicating with external devices, such as a mouse, keyboard, scanner, or other input devices not shown in  FIG. 3 . Likewise, WWW origin server  300  may further comprise additional mass storage facilities such as CD-ROM/DVD-ROM drive  326  and hard disk drive  338 . Hard disk drive  338  is utilized by WWW origin server  300  to store, among other things, application programs, databases, and program data used by WWW server application program  330 . For example, customer databases, product databases, image databases, and relational databases may be stored.

Restrictor  625  may restrict the device from receiving rich media presentations. According to one embodiment, restrictor  625  determines when the request for the rich media presentations is coming from a supported site. A supported site is a site on the network that has an affiliation with the provider of the rich media presentations. For example, a site not affiliated with the provider may attempt to incorporate the rich media presentations on their site. When the rich media presentations are requested by the device, restrictor  625  will recognize that the request is coming from an unaffiliated site and deny access. Restrictor  625  may be programmed to do many other tasks. For example, restrictor  625  may be programmed to return different versions of rich media presentations having varying capability based on the site location or some other attribute. 
     When the request for the rich media presentations moves beyond restrictor  625 , device trackers and detectors  650  determines the requesting device&#39;s attributes (See  FIGS. 8 ,  10 , and  11  and related discussion). Generally, device trackers and detectors  650  determine the attributes to send optimized rich media presentations to the requesting device. Based on the attributes of the requesting device, the rich media presentations are assembled. An example illustration of the operation of the rich media presentation system will now be described. 
     The object handlers including presentation package assembler  630 , virtual player assembler  635 , and media package assembler  640  may create their respective packages in advance of a request by a device or create the packages “just in time” (JIT) to meet the requesting device&#39;s configuration. For example, virtual player assembler may encode the virtual player package to be optimized for a WINDOWS 98 operating system using Windows Media Player V7.0 or some other device. According to one embodiment, the encoded virtual player packages are stored in a database and sent to a CDN and cached for a predetermined time. According to another embodiment, the virtual player packages are encoded when requested by a device. 
     Virtual player assembler  635  creates a virtual player for the requesting device. Different media players may be used by the virtual player. For example, Microsoft&#39;s Media Player and Real Networks&#39; Media Player may be used by the virtual player to play the media packages. The virtual player assembler uses attributes determined by device tracker and detectors  650  to create optimized virtual player code for the requesting device. Instead of an e-retailer having to include code on a web page for every possible media player, the e-retailer only includes a single line of code. The line of code is simply a request for an include file from a server. This include file contains the required JavaScript functions for a given browser and for the implementation of the videos relating to the presentation package and media package on a given web page. According to one embodiment, e-retailers place this line of code at the top of the body section of each Web page where a video will be available to the requesting device. 
     When loading a Web page containing the code, a network device requests the include file from servers relating to the provider. Before the virtual player code is delivered to the network device to be stored in network device content  605 , device trackers and detectors  650  performs operating system and browser detection. This detection allows the virtual player assembler  635  to return the appropriate include file, the contents of which are browser specific. If the provider does not support a device&#39;s configuration, the provider sends required packages containing stub functions. The returned include file including the browser and system specific code is approximately 18 KB in size and will remain in the requesting device&#39;s browser cache. Thereafter, each time a requesting device requests the include file, the provider instructs the browser to use the copy of the file stored in the cache. A requesting device downloads this file again only if there has been a change to the include file on the server-side, or when the include file cannot be found in the cache. Example syntax for this line of code is as follows: 
     
       
         
           
               
               
             
               
                   
                   
               
             
            
               
                   
                 &lt;script src=“http://ondemand.vendaria.com/envision/idletize.idlet” 
               
               
                   
                 language=“JavaScript1.2” type=“text/javascript”&gt;&lt;/script&gt; 
               
               
                   
                   
               
            
           
         
       
     
     Presentation package assembler  630  sets the presentation attributes relating to the virtual player and media package. A presentation package line of code is included in the e-retailers Web page requesting a presentation package include file from a server. According to one embodiment, the presentation package include file contains creative specific presentation-package information, a combination of a “Watch Video” button, a customized media player skin, and a presentation type (embedded or popup). Multiple presentation packages may be used by the e-retailer. For example, a different package for each video on your site may be used. The presentation package include file is approximately 4 KB in size and remains in the requesting device&#39;s browser cache. Thereafter, each time the presentation package include file is requested by the device, the provider instructs the browser on the requesting device to use the copy of the file stored in the cache. A requesting device downloads this file again when there has been a change to the presentation package include file or when the file cannot be found in the cache. Because e-retailers will likely use the same presentation package on multiple product pages, the speed and performance of the media presentation will improve markedly once a device has downloaded the presentation package include file. An example syntax for this line of code is as follows: 
                                &lt;script src=“http://ondemand.vendaria.com/envision/{IdletPseudonym}.       idlet” language=“JavaScript” type=“text/javascript”&gt;&lt;/script&gt;                    
where: {IdletPseudonym} is a value that uniquely identifies an e-retailer&#39;s presentation package.
 
     The code in the presentation package include file allows many presentation attributes relating to the rich media presentation to be set. For example, the rich media presentation&#39;s precise play location on a Web page may be set. A skin for the virtual player may be set. Images for buttons may be set. For example, an image separate from the default image for the “watch video” button may be set. The length of the rich media presentation may be displayed at a defined location. The presentation package and/or virtual player window may be automatically closed once a rich media presentation has stopped playing. In addition, text links may be used instead of buttons with images to trigger the start of a rich media presentation. Other presentation attributes may also be set. The attributes may be set within a Web page, or may be set using an API. The following is an example syntax for defining some of the presentation attributes associated with the rich media presentation on a Web page. 
     
       
         
           
               
             
               
                   
               
             
            
               
                 &lt;script language=“JavaScript” type=“text/javascript”&gt; 
               
               
                 var vnd_idletOverride_{IdletPseudonym} = new 
               
               
                 vnd_objIdletOverride({LocationTop}, {LocationLeft}, “{Locator}”, 
               
               
                 “{BURL}”, {ShowLen}, {CenterScreen}, {AutoHide}); 
               
               
                 &lt;/script&gt; 
               
               
                   
               
            
           
         
       
     
     where:
         {IdletPseudonym} is a value that uniquely identifies an e-retailer&#39;s presentation package.   {LocationTop} is the top coordinate of the player skin or video, if no skin is selected.   {LocationLeft} is the left coordinate of the media skin or video, if no skin is selected.   {Locator} is the name of an image object located on the page used for positioning the top and left coordinates of the media player skin or video, if no skin is selected.   {BURL} is the complete URL of the image you will use to start a video in lieu of the “watch video” button.   {ShowLen} is the indicator that determines if text describing the length of the video will appear next to the Watch Video button.   {LocCenterScreen} is the indicator that determines if the skin and media player will be centered in the middle of the screen. If the value is set to false, then the skin or media player will be located based on the default attributes of the presentation package or the override values found in {LocationTop} and {LocationLeft} or {Locator}.   {AutoHide} is an optional indicator that determines if the media player layers disappear upon completion of a video. If the value is true, the skin and/or media player disappear immediately upon completion of the video; if false, the skin and/or media player will remain displayed on the page along with the final frame of the video.       

     The video may also be set to automatically start playing. Auto-play functionality enables a video to start playing immediately after a Web page has been loaded in a requesting device&#39;s browser. For example, this feature might be used to play a video welcoming an on-line consumer to a site or to provide instructions to consumers. According to one embodiment, e-retailers include the autoLoad function in the onload event in the body tag as follows: &lt;body on Load=“vnd--autoLoad( )”&gt; 
     Media package assembler  640  assembles the combination of multimedia specific code and returns a media package include file to the requesting device. A third line of code is included within the e-retailers Web pages where the e-retailer would like a watch video button to appear on a product page. A server downloads the approximately 1 KB media package include file in a requesting device&#39;s browser cache each time the device accesses a Web page where a rich media presentation exists. An example syntax for this line of code is as follows: 
                                &lt;script src=“http://ondemand.vendaria.com/envision/       {AdletPseudonym}.adlet?idlet={IdletPseudonym}” language=“JavaScript”       type=“text/javascript”&gt;&lt;/script&gt;                    
where:
 
{AdletPseudonym} is a value that identifies a unique combination of a video in a video library and an e-retailer offering that video to on-line consumers. {IdletPseudonym} is a value that uniquely identifies an e-retailer&#39;s presentation package.
 
     Stream switch  645  may be selected to provide streaming content to the requesting device. 
       FIG. 7  shows an overview of the rich media presentation system, in accordance with one or more embodiments. As shown in the figure, rich media presentation system  700  includes device  705 , restrictor  715 , web document  710 , device specific package requester block  720 , cache checking block  725 , caching block  730 , generate package block  735 , and provide packages block  740 . 
     The operation of rich media presentation system  700  will now be described. Device  705  requests client&#39;s web document  710  that initiates a request for rich media presentations from the provider. Upon accessing web document  710 , device  705  requests optimized packages from the provider. The request goes through restrictor block  715  that may restrict access to the provider upon predefined conditions. For example, if the client is not affiliated with the provider the request for the packages may be denied. When the request is not denied package request block  720  requests device specific packages from the provider. Cache checking block  725  determines whether the packages are cached. If so, the packages are provided to device  705  from the cached location by package provider block  740 , such as a content delivery network. When the packages are not cached the provider generates the packages specific to the device and caches them at which point, package provider block  740  provides the packages to device  705 . 
       FIG. 8  illustrates an attribute inquiry system containing a set of example basic attributes of network devices, according to one embodiment. Generally, attribute inquiry system  800  determines the requesting device&#39;s basic configuration including the operating system, browser, and media player used by the requesting device. 
     Server  805  communicates with the requesting device and receives basic configuration information in return. The configuration information is used to help optimize the requesting device&#39;s media experience. According to one embodiment, javascript code is executed on the requesting device that sends the basic attribute information to server  805 . 
     For example, server  805  receives the operating system (OS) and browser used by the network device (block  830 ). For example, the requesting device of block  810  has a configuration using the WINDOWS XP operating system and using the Internet Explorer 6.0 browser. The requesting device of block  820  uses the UNIX operating system and uses Netscape 4.5 as the browser. The requesting device of block  840  uses the WINDOWS ME operating system and uses Internet Explorer 5.0 as the browser. The requesting device of block  850  uses the WINDOWS NT operating system and Netscape 4.75 as the browser. The requesting device of block  820  uses the UNIX operating system and Netscape 4.5 as the browser. The requesting device of block  870  is a mobile device. According to this embodiment, server  805  receives the mobile device&#39;s OS, browser, as well as its media player information. Similarly, server  805  receives the requesting device&#39;s media player according to one embodiment (block  860 ). The media player may be any media player type. For example, two popular media players include Real Player developed by Real Networks Corp. and Windows Media Player developed by Microsoft Corp. In addition to obtaining the brand of media player, server  805  also obtains the version of the media player. The media player information is used to produce the virtual player packages to be delivered to the requesting device. 
       FIG. 9  shows an overview process of providing rich media presentations to an authorized network device, according to one embodiment. After a start block, the logical flow moves to block  910  where a determination is made as to whether the network device is authorized to receive the rich media presentations. A device may not be authorized if the device is requesting the rich media presentations from an unaffiliated site. A site may not be affiliated when it does not have a relationship with the provider of the virtual player packages. Stepping to decision block  920 , a decision is made as to whether the network device is authorized to receive the rich media presentations. When the network device is not authorized, the process moves to block  930 , at which point the network device is refused service. When the service is refused, the process steps to an end block. When the network device is authorized, the process moves to block  940 , where the network device&#39;s attributes are determined (See  FIGS. 10 and 11  and related discussion). Moving to block  950 , the rich media presentations needed by the device are provided to the device (See  FIGS. 12-13  and related discussion). The process then steps to an end block. 
       FIG. 10  illustrates a process for determining attributes related to a network device, according to one embodiment. After a start block, the logic flows to block  1010 , where the process detects the basic operating attributes of the requesting device. The basic operating attributes of the device are used to help create rich media presentations that are optimized for the requesting device. According to one embodiment, the basic attributes include the operating system, browser, and media player used by the requesting device. Other basic attributes may be used depending on the content to deliver to the requesting device. Moving to decision block  1020 , a decision is made as to whether the basic operating characteristics are supported by the rich media presentation system. When the operating characteristics of the requesting device are not supported, the logical flow moves to block  1030  at which point the requesting device is informed that it is not supported. When the basic operating characteristics of the requesting device are supported, the process flows to block  1040  where additional attributes are obtained from the requesting device. The additional attributes provide the system with information that allows further optimization of the delivery of the content (See  FIG. 11  and related discussion). The logical flow then ends. 
       FIG. 11  illustrates a process for retrieving additional attributes from the network device, according to one embodiment. After a start block, the logical flow moves to block  1110  where the language used by the device is determined. The determined language is used to provide the device with content matching their language preference. For example, if the determined language is Spanish, then the rich media presentations will be delivered to the device such that Spanish is supported. Similarly, if the determined language is English, then the rich media presentations are encoded for English. Flowing to block  1120 , the network bandwidth is determined. The network bandwidth may be determined many different ways. According to one embodiment, the bandwidth is determined automatically by performing a download test on the requesting device. The requesting device may download a very small file having a predetermined size for a given period of time. The bandwidth is determined based on the number of files successfully downloaded for the given period of time. As the network conditions may change over time, the download test may be repeated. Moving to block  1130 , a determination is made as to whether a firewall is present on the requesting device. Transitioning to block  1140  permissions on the requesting device are determined. For example, permissions may be set that disable the ability to perform certain operations across a network. Moving to block  1150 , other attributes may be determined. Another attribute may be a protocol restrictions attribute or the other attributes may include any attributes that help to optimize the rich media presentations for the requesting device. 
       FIG. 12  illustrates a process for selecting a content provider to provide a rich media presentation to a device, according to one embodiment. After a start block, the process moves to decision block  1210 , where the process determines whether the rich media presentations needed for the device are cached. When the rich media presentations are not cached, the process moves to block  1220  where the process creates a rich media presentation for the requesting device. Generally, the rich media presentation may be any or all of the following: a virtual player, a presentation package and a media package. Moving to block  1230  the rich media presentation is cached for later retrieval by a device. Transitioning to block  1240 , the rich media presentation is delivered to the device. When the rich media presentation is cached the process steps to block  1250  at which point the cached rich media presentation is sent to the device. The process then steps to an end block and terminates. 
       FIG. 13  shows a process for providing rich media presentations to a device, according to one embodiment. After a start block, the process moves to decision block  1310 , where a determination is made as to whether an up-to-date virtual player is already on the device. A virtual player is provided to the device when a virtual player is not in a cache on the device, or when an updated virtual player is available from the provider. When a virtual player is not on the device, the process moves to block  1320 , at which point a virtual player package is created for the device. 
     The process transitions to decision block  1330 , where a determination is made as to whether an up-to-date presentation package is already on the device. A presentation package is provided to the device when a presentation package is not in a cache on the device, or when an updated presentation package is available. When a presentation package is not on the device, the process moves to block  1340 , at which point a presentation package is created for the device. 
     The process steps to decision block  1350 , where a determination is made as to whether an up-to-date media package is already on the device. A media package is provided to the device when a media package is not in a cache on the device, or when an updated media package is available. When a media package is not on the device, the process moves to block  1340 , at which point a media package is created for the device. According to one embodiment, a media package is provided to the device at each request as the media package is typically very small in size (approximately 1K). 
     Moving to block  1370 , the created packages are provided to the device. 
       FIG. 14  shows a process for an e-retailer to create and modify rich media presentations, in accordance with one or more embodiments. After a start block, the process moves to block  1410 , where the e-retailer, or some other party, may generate rich media presentations utilizing a Virtual Player Exposed API that is not device specific. Transitioning to decision block  1420 , a decision is made as to whether the presentation or media packages are to be updated. When the packages are not updated, the process steps to an end block. When they are to be updated, the appropriate updates are made and the process moves to block  1430  at which point the device receives the changed packages. The process then steps to an end block.
