  • This invention relates in general to the field of computer networks, and more particularly to a dedicated internet access device and method for interfacing the device with the internet .
  • the internet has had a dramatic impact on both the American public and American businesses.
  • One important way that the internet has impacted the public and businesses is that the internet has made a vast amount of information easily available to anyone with access to a personal computer.
  • the public has come to depend on the Internet to follow news, weather and financial markets. Businesses typically use the Internet to perform basic product and service delivery functions such as tracking information on customer orders and business inventories.
  • Another important way that the Internet has impacted the public and businesses is that the Internet has simplified communications between individuals and groups. For instance, e-mail and chat sent over the Internet are now commonly used in the place of regular mail and telephone calls. Recently, the introduction of voice chat over the Internet has gained popularity as a replacement for long distance telephone calls.
  • the Internet has, in large part, grown in popularity as a means for transferring information and for communications because interfacing with the Internet has become increasingly simple.
  • the introduction of the World Wide Web as a format for information available through the Internet has increased the popularity of the Internet as a tool for individuals and businesses.
  • the primary reason for the growth in popularity of the World Wide Web (“WWW”) format is that the Hyper Text Markup Language (“HTML”) and Hyper Text Transfer Protocol (“HTTP”) used by the World Wide Web enables the presentation of graphical information through a web browser loaded on a user's personal computer.
  • Web browsers support interesting graphical displays that enhance the presentation of information, and allow users to navigate through various World Wide Web sites by pointing and clicking on Universal Resource Locators ("URLs").
  • URLs Universal Resource Locators
  • the World Wide Web has encouraged a greater proportion of the population to explore the Internet, but continued rapid growth in Internet use has been hampered due to a number of factors.
  • One major factor that has limited growth of Internet usage is the complexity of interfacing with the Internet with available hardware and software systems.
  • Another important factor in limiting the growth of Internet usage is the cost of interfacing with the Internet, both in the purchase of hardware for interfacing and a service provider that allows interfacing.
  • Hardware complexity is, in many respects, inherent with the conventional personal computer. Setting up a personal computer presents a daunting task to individuals who are not technically literate. For instance, setting up a personal computer generally involves connecting the computer with a monitor, printer, speakers, microphone and other peripherals using a series of wires. The personal computer generally uses a hard drive to store an operating system that is loaded into local RAM memory upon boot-up of the computer. Variations in hardware configurations, such as can result when a user attempts to incorporate an additional peripheral device with the computer, often result in changes to the operating system and related files . Software complexity presents yet another barrier to novices trying to interact with the Internet . Once a user has a personal computer up and running, the user generally must interact with software loaded on the hardware in order to dial up an Internet service provider. Once interfaced with a service provider, a user must then interact with the Internet through a web browser. To locate desired information, the user generally has to have a basic understanding of how the Internet works and how the user's web browser operates within the Internet .
  • a user Once a user has set up a personal computer and arranged an interface with the Internet, the user must also overcome software related complexity. For instance, Internet service providers generally interface users through dial-up networking that requires the user to provide the computer with a telephone number and password for the Internet service provider. Once a connection is established, the user must generally operate a web browser to interact with the Internet through the Internet service provider portal.
  • An uninitiated user tends to have difficulty locating information of interest by either typing a URL, or searching for particular information in a World Wide Web directory or with a search engine.
  • graphical displays tend to simplify Internet interaction, typical web pages nonetheless include an overwhelming amount of information. An uninitiated user may have difficulty identifying legitimate information of interest among the large number of advertisements and other information on a web page.
  • web browsers may have a number of plug-ins that must be added to the browser for the browser to be compatible with certain information stored on the Web. These plug-ins typically must be downloaded as files to the user's computer and then loaded on the computer, typically in the hard drive, as an executable file.
  • e-mail may be supported by software loaded on a web portal or by a separate program on the user's personal computer. Users generally must understand e-mail addresses and some detail of the operation of the user's e-mail program in order to communicate with e-mail. When files or graphics are attached to e-mail messages, users must generally learn to navigate their computer's operating system to store the file or graphic and to find a compatible program within the personal computer for displaying the file or graphic.

  • dial-up numbers may be modified in response to load conditions, such as the number of dial-up attempts to one or more servers so that loads are balanced between servers, in response to failures of a server so that dial-ups are redirected from a failed server to a working server, and to enact planned reconfigurations such as moving users to a new mail server or moving service from one connection server site to another .
  • Internet access device 10 operates in two modes: an off-line mode and an on-line mode.
  • the on-line mode access device 10 dialed into a service network through a portal site.
  • the off-line mode the access device is disconnected from the network but continues to operate by rendering content stored as local information in RAM cache memory.
  • the distinction between the on-line and off-line modes of operation may be transparent to the user.
  • Offline operation is enhanced and kept current by periodically having access device 10 connect to a portal site to update local information stored in the cache memory of access device 10, to retrieve incoming mail, and to send outgoing mail. If, for instance, a user renders information stored in cache memory shortly after the information is downloaded to access device 10, the user will effectively view current information without having to wait for access device 10 to connect to a portal site and download the information.
  • An effective cache update policy is an important component to reducing latency for the user of an access device 10.
  • Updates to the cache of an access device 10 by downloading information to the access device 10 from a portal site take into account the convenience of the user and the load on the portal site. For instance, updates may be timed to reduce interference with the user's telephone. Similarly, updates may be timed to balance congestion at the portal site and to maximize bandwidth usage.
  • an initial cache update schedule may have periodic updates, such as once a day, that occur within a set period of a time interval, such as one to three o'clock in the morning, with the time of each access device's update selected as a uniformly distributed random variable within the time interval to avoid having too many devices connecting to a given portal at the same time and overloading the network.
  • the update schedule may be stored as part of user profile information for each access device, or may be stored as part of the user configuration profile on one or more portal sites associated with each access device.
  • an adaptive cache update engine can modify the cache update schedule of access devices that interface with a given portal site based upon the activity of each access device and network conditions associated with the portal site.
  • an activity log associated with each access device may be stored on each access device or the portal site associated with the access device.
  • the activity log for a given access device may track user activity associated with the access device through a number of factors, such as key strokes, e-mail activity or browsing activity.
  • the adaptive cache update engine analyzes the activity log to determine when to update the cache of an access device as well as to determine how best to update the access device base upon a prediction of the user's future activities. For instance, if a user reads mail more frequently than the user performs other activities, then the cache update schedule may update mail more frequently than it performs other activities.
  • a cache update schedule may update mail twice daily, once in the morning and once at night, may update stock market information shortly after the stock market closes, and may update sports news shortly before the user goes to bed.
  • the cache update engine can significantly reduce latency in the on-line mode of operation by predicting the future information requests of the user of an access device and downloading the predicted information for storage in the cache of the user's access device.
  • the cache update engine may comprise a neural network program that uses the activity log to predict future information requests, and instructs the downloading of the predicted future information requests.
  • the cache update engine may identify this pattern and update the cache with the CNNfn page when the update engine detects that the user has requested the CNN home page.
  • the cache update engine could be associated with the user's access device, the portal site associated with the access device, or with the CNN server. Reduced latency and greater user satisfaction result when the user is able to render the CNNfn information without having to wait for the information to be transferred to the user's access device.
  • Access device 10 is depicted along with a graphical user interface presented by device 10 on flat panel display 22.
  • Access device 10 is run with a simple computing architecture having a motherboard 52 that supports a processor 54, memory cache 56 and programmable read only memory (“PROM”) 58.
  • Processor 54 may be an IBM compatible processor such as are available through Intel and Advanced Micro Devices, or similar type of processor that is capable of running a browser.
  • Processor 54 may be an older and less expensive version of a conventional processor to reduce -the cost of access device 10 as long as processor 54 can expeditiously handle advanced browser functions such as video chat.
  • PROM 58 stores an embedded operating system, including device drivers, and an embedded browser as well as user profile information to support operation of access device 10.

  • the user inputs the channel into pointing device 20 either as a channel number in number pad 40, by pointing with arrow pointer 38, or by scrolling with scroll wheel 36.
  • Transmitter receiver 32 sends a signal to transmit receive module 68 that, together with processor 54, retrieves the desired information for display on flat panel display 22. In this way, access device 10 emulates the operation of a television appliance.
  • Each channel may include several subchannels. For instance, when a user selects news channel 2, a graphical user interface may present the user with options for obtaining news, such as channels 21-29, with each channel providing a different news source or news topic.
  • Figure 3A depicts an exemplary channel guide which a user may reference to locate relevant information.
  • FIGURE 3B depicts an exemplary display of a CNN Web page which may be display if the user selects a news channel number for CNN.

  • FIGURE 4 a web page is depicted that allows a user and those approved by the user to initiate and alter address book information. Alterations to a user's address book are made through an address book server, such as an LDAP server, for secure storage on a portal site.
  • the user may screen changes made to the user's address book for acceptance or rejection by the user before the changes become effective.
  • access device 10 can also receive inputs indicating that the user of access device 10 is wanted for chat sessions or voice chat sessions, even if the user is not currently logged onto the internet.
  • One current drawback to conventional chat applications is that a user must be on-line in order to detect that another user is interested in having a chat session.
  • the present invention sends messages through the telephone system as a notification to a requested member, and allows that member to decide whether or not to enter the chat session. Referring now to FIGURE 5, at step 302, a user at an access device X requests a chat session with a user at an access device Y.
  • a portal site interfaced with access device X determines if access device Y is interfaced with the internet. If access device y is interfaced, then at step 306, a chat session is connected between access devices X and Y. If access device Y is not interfaced with the internet, then notice is sent to access device Y or its user through one of a number of available techniques .
  • access device X disconnects from the portal site and, at step 312, initiates a call to the telephone number associated with access device Y.
  • Access device Y detects the incoming call as a chat request, for instance by identifying the number of the originating call with caller ID, and informs the user of the chat request through, for instance, an audible sound or a message on the display of access device Y.
  • the user of access device Y will know to check for chat message alerts when the user receives a single telephone ring, and can view the display as a chat message log to identify chat requests received over a predetermined period of time. In this manner, longdistance fees may be avoided.
  • access device X reconnects to its portal site to await notice as to whether or not access device Y has interfaced with the internet at step 316. If access device Y does interface with the internet, then at step 306 the chat session may be connected. If access device Y does not interface with the internet, for instance after a predetermined lapse of time, then at step 318 access device X will indicate failure of the chat request to its user.
  • the portal site may initiate notice to the user of access device Y of the chat request .
  • the portal site may contact access device Y through a dial-up modem, or may send a request through the internet to another portal site that places a local telephone call to access device Y.
  • Access device Y may issue notice to its user of the chat request as was described above.
  • the telephone may be allowed to ring until the user answers so that the portal site may provide the user with an audible message of the chat request.
  • the portal site may use voice creation and recognition software to inform the user of access device Y that, "User of access device X has requested a chat session.”
  • the user of access device Y may then join the chat session at step 306.
  • internet access device 10 uses different caller ID information to distinguish between a plurality of phone call types, such as a voice call, a fax, a chat request, incoming mail, or new content on a specified channel of interest to the user of access device 10.
  • An incoming call identification module (“CIM") 93 loaded on access device 10 detects the origination of the call and compares the origination against a known list of potential originations to map the call to a source application. For instance, a portal site associated with a given access device will use a "chat" originating number when contacting the access device for a chat session, and an "e-mail" originating number when contacting the access device for new e-mail notification.
  • a call alert module
  • CAM 95 matches the application to a corresponding alert mechanism. For instance, chat and e-mail alerts may provide a unique ring sound/tone, blinking light, or a voice that states "you have chat” or "you have e-mail.”
  • a call response module (“CRM”) 97 will then match an application with an appropriate response to identification provided by the CIM. For instance, the CRM may provide a busy tone, initiate an e-mail download, initiate a chat session, provide a custom voice message for voice calls, or contact a server for content update.
  • FIGURE 6 a block diagram depicts software modules of access device 10 and server 100. Access device 10 supports software storage in either flash PROM 58 or local cache 56.
  • Access device 10 has device drivers 80 for operating hardware devices including a keyboard device driver 82, a communications link driver 84, a magnetic card swipe driver 86, a remote control driver 88, and a file system driver 90. Other device drivers may be included as appropriate for operating devices loaded in access device 10.
  • An embedded operating system module 92 cooperates with device drivers 80 to ensure proper operation of access device 10.
  • Operating system module 92 can be conventional operating systems embedded in PROM 58 such as, the Linux operating system, WINDOWS, the disk operating system (DOS) or other basic operating systems.

  • Real audio layer 96 cooperates with embedded web browser 94 to enable audio functions including streaming audio.
  • Web browser 94 generally interfaces through channels provided by server 100, but may also use a web bypass 98 to support direct access to the World Wide Web.
  • file information may be transferred through web browser 94 and written into flash PROM 58 with operating system module 92.
  • This enables software such as browser software, operating systems software or device driver software, to be updated periodically without input or intervention by the user of access device 10.
  • Server 100 interfaces with access device 10 through the embedded web browser module 94, and performs the functions of connecting access device 10 to the Internet, collection and selection of information from the World Wide Web, and focusing of the information on the World Wide Web for the user of access device 10.
  • a file system 102 of server 100 includes a conventional cache 104 to store realtime data, and files for storing cookies information 106, user profiles information 108, and user application data information 110.
  • An LDAP module 112 interacts with cookies information 106 and user profiles information 108 to perform access management functions of allowing predetermined access devices to interact with server 100 and identifying information specific to each user.

  • Virtual tuner 132 accepts channel request information from access device 10 and provides single topic channel information to access device 10 for display to a user. Virtual tuner 132 also supports direct World Wide Web interface for access device 10 through Web bypass 98.
  • virtual tuner 132 provides next-channel functionality to reduce the time needed to update new information sent to access device 10. More specifically, virtual tuner 132 predicts the next possible requests by access device 10 and sends the next channel information to access device 10 for storage in cache 56. If, in fact, a user requests the predicted next channel information, then the time needed to render the information is reduced since the information does not have to be downloaded from server 100 to access device 10.
  • Presentation engine 130 cooperates with a user database 136 and style sheet database 138 to prepare information for transfer to access device 10.
  • User database 136 provides LDAP functionality by storing user profile information, access management information and cookie management information on a user-by-user basis.
  • User database 136 communicates active user information to an on-line user list 140 to support chat activities.
  • Style sheets database 138 stores format information for topical channels and for specific users. For instance, news may have a style sheet similar to a newspaper format, and may be provided in enlarged fonts for specific users having poor eyesight. By comparison, weather information may be provided in a television format with active radar screen images and graphical icons to demonstrate forecasts.
  • Presentation engine 130 obtains information from an advertising engine 142, an e-mail engine 144 and a content selection and collection engine 146.
  • Advertising engine 142 provides information from advertisers for presentation to users based on a number of factors including the channel requested by the user and the user's demographics. For instance, presentation engine 130 may insert advertising directed towards specific age groups based upon age information obtained from user database 136 for a specific user.
  • E-mail engine 144 provides e-mail communication support to users through the e-mail channel as previously described.
  • Content selection and collection engine 146 accepts information from the World Wide Web and stores the information in topical groups such as Topic A 148.
  • content selection and collection engine 146 accepts XML data from predetermined sources, such as web sites that provide news or financial information, and provides the XML information from topical storage to presentation engine 130 for translation into HTML web pages according to style sheets stored in style sheet database 138.
  • predetermined sources of information may agree to periodically update content selection and collection engine 146 with new information that updates the topical databases.
  • content selection and collection engine 146 may actively search predetermined sites on the World Wide Web to locate desired information. In this manner, server 100 acts as a lens that focuses vast quantities of information most likely to be of interest to particular users and thus reduce the complexity of locating such information.
