`OFFLINE VIEWING OF INTERNET
`CONTENT WITH A MOBILE DEVICE
`
`BACKGROUND OF THE INVENTION
`The present invention relates to personal mobile comput(cid:173)
`ing devices commonly known as mobile devices. More
`particularly, the present invention relates to a system and
`method for offline viewing of content from a wide area
`network, such as content from the Internet, with the mobile
`device.
`Mobile devices are small electronic computing devices
`often referred to as personal digital assistants. Many such
`mobile devices are hand-held devices, or palm-size devices,
`
`:Vh:~~b~~:!:JtebZ!~e~~~:;::!:tihe ~~~:~~:ee~~~Y- 15
`

`to this architecture and make available to the mobile device
`user separate script files and data files. In many cases, this
`requires the content provider to maintain two different types
`of Internet sites, one for browsers that expect to receive
`5 HTML (hypertext markup language) pages for rendering
`information, and a second site using the above-described
`architecture.
`Another technique for "offline" browsing with a desktop
`computer involves traversing or "crawling" through a par-
`10 ticular Internet site and storing the information locally. If the
`information is stored as pages, simple transfer of this infor(cid:173)
`mation to the mobile device would not be efficient since the
`mobile device typically has limited memory resources and
`the information may contain portions that cannot be used or
`are unsuitable for the mobile device. Thus, memory may be
`wasted in storing irrelevant information.
`There is an ongoing need to provide efficient offline
`browsing of content, particularly, when performed on a
`mobile device. The downloading of information for offline
`20 browsing should allow access to existing Internet sites
`without requiring the content provider to maintain separate
`Internet sites.
`
`Held PC ( or H/PC) having software provided by Microsoft
`Corporation of Redmond, Washington.
`Generally, the mobile device includes a processor, ran(cid:173)
`dom access memory (RAM) , and an input device such as a
`keyboard and a display. The keyboard can be integrated with
`the display, such as where the keyboard is incorporated as a
`touch sensitive display. A communication interface is
`optionally provided and is commonly used to communicate
`with a desktop computer. A replaceable or rechargeable 25
`battery powers the mobile device. Optionally, the mobile
`device can receive power from an external power source that
`overrides or recharges the built-in battery.
`Commonly, the mobile device is used in conjunction with
`a desktop computer. For example, the user of the mobile 30
`device may also have access to, and use, a desktop computer
`at work or at home, or both. The user typically runs the same
`types of applications on both the desktop computer and on
`the mobile device. Thus, it is quite advantageous for the
`mobile device to be designed to be coupled to the desktop 35
`computer to exchange information with, and share informa(cid:173)
`tion with, the desktop computer.
`Another technique for providing information to such
`mobile devices is through a wireless transmission link. Such
`information can include electronic mail or pager information 40
`including news, weather; sports, traffic and local event
`information.
`In addition to the above-mentioned uses of the mobile
`device, there is also a desire to use the mobile device for
`"offline" browsing of Internet content. U.S. patent applica- 45
`tion Ser. No. 09/107,666 filed Jun. 30, 1998, entitled "SYS(cid:173)
`TEM FOR DELIVERING DATA CONTENT OVER A
`LOW BIT RATE TRANSMISSION CHANNEL" and U.S.
`patent application Ser. No. 09/107,941. filed Jun. 30, 1998,
`entitled "CHANNEL DEFINITION ARCHITECTURE 50
`EXTENSION" describe a system and method wherein Web
`or Internet content is rendered on a mobile device using a
`channel definition format, (CDF) file, a set of script files and
`a set of data files. Briefly, navigation of the content on the
`mobile device is performed using the CDF file, which 55
`includes references to the script files and the data files. When
`a particular page of content is to be displayed, a script file
`is accessed and is used to operate upon the data file in order
`to render the desired information. This architecture allows
`wireless updates of data files, because, typically, only the
`data files will change with time. However, if desired, the
`CDF file and the script files can also be updated wirelessly.
`Likewise, each of these files can be updated through syn(cid:173)
`chronization of the mobile device with the desktop com(cid:173)
`puter.
`Although the above-described system allows wireless
`updates for Internet content, the content provider must adapt
`
`SUMMARY OF THE INVENTION
`
`A method and system for transferring offline browsing
`content information of a wide area network from a host
`computer to a mobile device includes connecting the mobile
`device to the host computer and obtaining characteristic
`information of the mobile device pertaining to at least one of
`hardware and software capabilities of the mobile device. The
`content information is transferred from the host computer to
`the mobile device as a function of the characteristic infor(cid:173)
`mation.

`suitable and desired function keys which are also provided
`for accomplishing certain user input functions.
`FIG. 4 is another simplified pictorial illustration of the
`mobile device 18 in accordance with another preferred
`embodiment of the present invention. Mobile device 18, as 5
`illustrated in FIG. 4, includes some items which are similar
`to those described with respect to FIG. 3, and are similarly
`numbered. For instance, mobile device 18, as shown in FIG.
`4, also includes touch sensitive screen 45 which can be used,
`in conjunction with stylus 46, to accomplish certain user 10
`input functions. It should be noted that the display 45 for the
`mobile device as shown in FIGS. 3 and 4 can be the same
`size as one another, or different sizes from one another, but
`would typically be much smaller than a conventional display
`used with a desktop computer. For example, display 45
`shown in FIGS. 3 and 4 may be defined by a matrix of only
`240x320 coordinates, or 16x160 coordinates, or any other
`suitable size.
`The mobile device 18 shown in FIG. 4 also includes a
`number of user input keys or buttons (such as scroll buttons
`47) which allow the user to scroll through menu options or
`other display options which are displayed on display 45, or
`which allow the user to change applications, without con(cid:173)
`tacting display 45. In addition, the mobile device 18 also
`shown in FIG. 4 also preferably includes a power button 49
`which can be used to turn on and off the general power to the
`mobile device 18.
`It should also be noted that, in the embodiment illustrated
`in FIG. 4, mobile device 18 includes a handwriting area 51.
`Handwriting area 51 can be used in conjunction with. stylus
`46 such that the user can write messages which are stored in
`memory 33 for later use by the mobile device 18. In one
`illustrative embodiment, the handwritten messages are sim(cid:173)
`ply stored in handwritten form and can be recalled by the
`user and displayed on the display screen 45 such that the
`user can review the handwritten messages entered into the 35
`mobile device 18. In another preferred embodiment, mobile
`device 18 is provided with a character recognition module
`such that the user can enter alpha-numeric information into
`mobile device 18 by writing that alpha-numeric information
`on area 51 with stylus 46. In that instance, character recog(cid:173)
`nition module in the mobile device 18 recognizes the
`alpha-numeric characters and converts the characters into
`computer recognizable alpha-numeric characters which can
`be used by the application programs 42 in mobile device 18.
`FIG. 5 and the related discussion are intended to provide
`a brief, general description of a suitable desktop computer
`16 in which portions of the invention may be implemented.
`Although not required, the invention. will be described, at
`least in part, in the general context of computer-executable
`instructions, such as program modules, being executed by a
`desktop computer 16 or mobile device 18. Generally, pro(cid:173)
`gram modules include routine programs, objects,
`components, data structures, etc. that perform particular
`tasks or implement particular abstract data types. Moreover
`those skilled in the art will appreciate that desktop computer 55
`16 may be implemented with other computer system
`configurations, including multiprocessor systems,
`microprocessor-based or programmable consumer electron-
`ics network PCs, minicomputers, mainframe computers, and
`the like. The invention may also be practiced in distributed
`computing environments where tasks are performed by
`remote processing devices that are linked through a com(cid:173)
`munications network. In a distributed computing
`environment, program modules may be located in both local
`and remote memory storage devices.
`With reference to FIG. 5, an exemplary system for imple(cid:173)
`menting desktop computer 16 includes a general purpose
`
`6
`computing device in the form of a conventional personal
`computer, including processing unit 48, a system memory
`50, and a system bus 52 that couples various system com-
`ponents including the system memory 50 to the processing
`unit 48. The system bus 52 may be any of several types of
`bus structures including a memory bus or memory
`controller, a peripheral bus, and a local bus using any of a
`variety of bus architectures. The system memory 50 includes
`read only memory (ROM) 54 and random access memory
`(RAM) 55. A basic input/output system (BIOS) 56, contain(cid:173)
`ing the basic routine that helps to transfer information
`between elements within the desktop computer 16, such as
`during start-up, is stored in ROM 54. The desktop computer
`16 further includes a hard disk drive 57 for reading from and
`writing to a hard disk (not shown) a magnetic disk drive 58
`15 for reading from or writing to removable magnetic disk 59,
`and an optical disk drive 60 for reading from or writing to
`a removable optical disk 61 such as a CD ROM or other
`optical media. The hard disk drive 57, magnetic disk drive
`58, and optical disk drive 60 are connected to the system bus
`20 52 by a hard disk drive interface 62, magnetic disk drive
`interface 63, and an optical drive interface 64, respectively.
`The drives and the associated computer-readable media
`provide nonvolatile storage of computer readable
`instructions, data structures, program modules and other
`25 data for the desktop computer 16.
`Although the exemplary environment described herein
`employs a hard disk, a removable magnetic disk 59 and a
`removable optical disk 61, it should be appreciated by those
`skilled in the art that other types of computer readable media
`30 which can store data that is accessible by a computer, such
`as magnetic cassettes, flash memory cards, digital video
`disks (DVDs) , Bernoulli cartridges, random access memo(cid:173)
`ries (RAMs), read only memory (ROM), and the like, may
`also be used in the exemplary operating environment.
`A number of program modules may be stored on the hard
`disk, removable magnetic disk 59, removable optical disk
`61, ROM 54 or RAM 55, including an operating system 65,
`one or more application programs 66 (e.g. downloading
`module 20), other program modules 67 (which may include
`40 synchronization module 24), and program data 68. A user
`may enter commands and information into the desktop
`computer 16 through input devices such as a keyboard 70,
`pointing device 72. Other input devices (not shown) may
`include a microphone, joystick, game pad, satellite dish,
`45 scanner, or the like. These and other input devices are often
`connected to the processing unit 48 through a serial port
`interface 76 that is coupled to the system bus 52, but may be
`connected by other interfaces, such as a sound card, a
`parallel port, game port or a universal serial bus (USE) . A
`50 monitor 77 or other type of display device is also connected
`to the system bus 52 via an interface, such as a video adapter
`78. In addition to the monitor 77, desktop computers may
`typically include other peripheral output devices such as
`speaker and printers.
`The desktop computer 16 may operate in a networked
`environment using logic connections to one or more remote
`computers ( other than mobile device 18), such as a remote
`computer 79. The remote computer 79 may be another
`personal computer, a server, a router, a network PC, a peer
`60 device or other network node, and typically includes many
`or all of the elements described above relative to desktop
`computer 16, although only a memory storage device 80 has
`been illustrated in FIG. 4. The logic connections depicted in
`FIG. 4. include a local area network (LAN) 81 and a wide
`65 area network (WAN) 82. Such networking environments are
`commonplace in offices, enterprise-wide computer network
`intranets and the Internet.

`When used in a LAN networking environment, the desk(cid:173)
`top computer 16 is connected to the local area network 81
`through a network interface or adapter 83. When used in a
`WAN networking environment, the desktop computer 16

`external, is connected to the system bus 52 via the serial port
`interface 76. In a network environment, program modules
`depicted relative to desktop computer 16, or portions 10
`thereof, may be stored in the remote memory storage
`devices. It will be appreciated that the network connections
`shown are exemplary and other means of establishing a
`communications link between the computers may be used.
`Desktop computer 16 runs operating system 65 that is
`typically stored in no-volatile memory 54 and executes on
`the processor 48. One suitable operating system is a "WIN(cid:173)
`DOWS" brand operating system sold by Microsoft
`Corporation, such as "WINDOWS 95" or "WINDOWS
`NT", operating systems, other derivative versions of Win- 20
`dows brand operating systems, or another suitable operating
`system. Other suitable operating systems include systems
`such as the "MACINTOSH OS" sold from Apple
`Corporation, and the "OS/2 PRESENTATION MANAGER"
`sold by International Business Machines (IBM) of Armonk, 25
`N.Y. Application programs are preferably stored in program
`module 67, in volatile memory or non-volatile memory, or
`can be loaded into any of the components shown in FIG. 5
`from a floppy diskette 59, CDROM disk 61, downloaded
`from a network via network adapter 83, or loaded using 30
`another suitable mechanism.
`FIG. 6 illustrates a method 100 for obtaining and down(cid:173)
`loading content from the content provider 12 through the
`desktop computer 16 and to mobile device 18. Each of the
`steps illustrated in FIG. 6 and in the flow diagram of FIG. 7 35
`are implemented using the downloading module 20, syn(cid:173)
`chronizing modules 24 and 26 and filter module 30,
`described above. At step 102, a user desiring to download
`content to mobile device 18 for oflline browsing preferably
`provides downloading user preferences that are used to 40
`access the desired content from content provider 12 and to
`limit the amount of content that is transferred to desktop
`computer 16, which is subsequently transferred to mobile
`device 18. The user preferences include the URL or similar
`address pointer used to access content provider 12 and 45
`specify content contained therein. The user preferences also
`act as a filter to limit the amount of content that is down(cid:173)
`loaded from content provider 12. Limitations can be
`
`8
`expressed using a number of different parameters. For
`instance, the user can impose a limit as to the total quantity
`of content that is to be downloaded from content provider
`12. Generally, the quantity is expressed in bytes; however,
`other units representing a quantity of digital data can also be
`used. If desired, the user can also limit how many levels of
`content organized in a hierarchical manner will be down(cid:173)
`loaded from content provider 12. Typically, hierarchical
`content stored at content provider 12 is accessed through
`"links", which allow the user to navigate up, down or
`directly to other portions of the hierarchical structure. In
`addition, content provider 12 may include links to "external"
`sites of content, which may be under the control of content
`provider 12 or be accessed through Internet 14 at other
`15 remote content providers. In one embodiment, the user
`preferences indicate whether or not to access and download
`content from the external sites.
`In a further embodiment, the user preferences can include
`user selections regarding the type of information that will be
`downloaded from content provider 12. For instance, content
`at content provider 12 can include text data, image or
`graphical data and/or sound or audio data. It may be desir(cid:173)
`able for the user to limit which types of data that are
`downloaded to desktop computer 16 and subsequently trans(cid:173)
`ferred to mobile device 18 because of memory availability
`in cache 28 and/or the existence or non-existence of other
`hardware on mobile device 18 such as whether or not sound
`support exists. By indicating the types of data to be down(cid:173)
`loaded at step 102, the user can avoid unnecessary transfer
`of data to mobile device 18, and minimize the time neces(cid:173)
`sary to complete downloading of content to desktop com(cid:173)
`puter 16. From step 102, program flow continues to step 104
`whereat downloading module 20 accesses content provider
`12 and downloads content therefrom in accordance with the
`user preferences as well as creates a CDF file. The content
`and CDF file are stored in cache 22.
`FIGS. 7A, 7B and 7C together illustrate an exemplary
`method 110 for downloading content from content provider
`12 based on user preferences. At step 112, downloading
`module 20 accesses content at content provider 12 in accor(cid:173)
`dance with the first or topmost specified URL or other
`address pointer and downloads the first page of content. If
`the HTML content does not exceed the user specified
`download limit at step 113, operational flow continues to
`step 114 whereat the HTML content is placed in cache 22
`and CDF format topmost channel tags are placed in the CDF
`file. Referring to Table 1 below the topmost tags are indi(cid:173)
`cated at "A".

`Operational flow then continues to step 130 in FIG. 7B to
`determine if image content is to be downloaded. At step 130, 25
`the user preferences are examined, and if images are to be
`downloaded, a list of image content URLs in the current
`HTML content is obtained at step 132. In steps 134, 136 and
`138, the images from the list of image content URLs are
`sequentially downloaded wherein the individual size of the 30
`image and/or the total amount of image content so far stored
`is compared with the user preferences, and if not exceeded,
`is stored in cache 22. For each image, a CDF format URL
`entry is provided in the CDF file. In Table 1, images are
`indicated at "B" for the topmost channel.
`Operational flow then continues to step 140 in FIG. 7C to
`determine if sound or audio content (for example, audio
`clips) is to be downloaded. Steps 140,142,144, 146 and 148
`are similar to steps 130, 132, 134, 136 and 138, discussed
`above. At step 140, the user preferences are examined, and 40
