The present invention relates techniques for allowing an Internet user to more easily build a personal home page on the user's own personal computer and more particularly to techniques for allowing such a user to more easily dynamically update the contents of the personal home page by including data acquired from existing pages at external sites on the World Wide Web.
The invention may be implemented as a method of dynamically updating a video page. A generated video page includes at least one updatable region. A source video page having a source region occupying a predetermined location is associated with the updatable region. The current contents of the source region are periodically retrieved and written into the updatable region of the generated video page.
The invention may also be implemented as a system for dynamically updating a video page. The system would include a monitor for presenting a visual display of the dynamically updatable video page and a video buffer for storing video data to be presented on the monitor. The video buffer would have at least one region allocated to dynamically updatable video data. A source control module would associate the buffer region with a source region occupying a predetermined location on a source video page. An acquisition module would periodically retrieve the current contents of the source region. A buffer control module would write the retrieved current contents into the region of the video buffer.
The invention may also be implemented as a computer program product including a computer usable medium having computer usable program code embodied therewith. The embodied program code would include program code for generating a video page having an updatable region. It would also include program code for establishing an association between a source region occupying a predetermined location on a source video page with the updatable region on the generated video page. It would further include program code for periodically retrieving the current contents of the source region and writing the retrieved contents into the updatable region of the generated video page.
As will be appreciated by one skilled in the art, the present invention may be embodied as a method, system, or computer program product. Accordingly, the present invention may take the form of an entirely hardware embodiment, an entirely software embodiment (including firmware, resident software, micro-code, etc.) or an embodiment combining software and hardware aspects that may all generally be referred to herein as a “circuit,” “module” or “system.” Furthermore, the present invention may take the form of a computer program product on a computer-usable storage medium having computer-usable program code embodied in the medium.
Any suitable computer usable or computer readable medium may be utilized. The computer-usable or computer-readable medium may be, for example but not limited to, an electronic, magnetic, optical, electromagnetic, infrared, or semiconductor system, apparatus, device, or propagation medium. More specific examples (a non-exhaustive list) of the computer-readable medium would include the following: an electrical connection having one or more wires, a portable computer diskette, a hard disk, a random access memory (RAM), a read-only memory (ROM), an erasable programmable read-only memory (EPROM or Flash memory), an optical fiber, a portable compact disc read-only memory (CD-ROM), an optical storage device, a transmission media such as those supporting the Internet or an intranet, or a magnetic storage device. Note that the computer-usable or computer-readable medium could even be paper or another suitable medium upon which the program is printed, as the program can be electronically captured, via, for instance, optical scanning of the paper or other medium, then compiled, interpreted, or otherwise processed in a suitable manner, if necessary, and then stored in a computer memory. In the context of this document, a computer-usable or computer-readable medium may be any medium that can contain, store, communicate, propagate, or transport the program for use by or in connection with the instruction execution system, apparatus, or device. The computer-usable medium may include a propagated data signal with the computer-usable program code embodied therewith, either in baseband or as part of a carrier wave. The computer usable program code may be transmitted using any appropriate medium, including but not limited to the Internet, wireline, optical fiber cable, RF, etc.
Computer program code for carrying out operations of the present invention may be written in an object oriented programming language such as Java, Smalltalk, C++ or the like. However, the computer program code for carrying out operations of the present invention may also be written in conventional procedural programming languages, such as the “C” programming language or similar programming languages. The program code may execute entirely on the user's computer, partly on the user's computer, as a stand-alone software package, partly on the user's computer and partly on a remote computer or entirely on the remote computer or server. In the latter scenario, the remote computer may be connected to the user's computer through a local area network (LAN) or a wide area network (WAN), or the connection may be made to an external computer (for example, through the Internet using an Internet Service Provider).
The present invention is described below with reference to flowchart illustrations and/or block diagrams of methods, apparatus (systems) and computer program products according to embodiments of the invention. It will be understood that each block of the flowchart illustrations and/or block diagrams, and combinations of blocks in the flowchart illustrations and/or block diagrams, can be implemented by computer program instructions. These computer program instructions may be provided to a processor of a general purpose computer, special purpose computer, or other programmable data processing apparatus to produce a machine, such that the instructions, which execute via the processor of the computer or other programmable data processing apparatus, create means for implementing the functions/acts specified in the flowchart and/or block diagram block or blocks.
These computer program instructions may also be stored in a computer-readable memory that can direct a computer or other programmable data processing apparatus to function in a particular manner, such that the instructions stored in the computer-readable memory produce an article of manufacture including instruction means which implement the function/act specified in the flowchart and/or block diagram block or blocks.
The computer program instructions may also be loaded onto a computer or other programmable data processing apparatus to cause a series of operational steps to be performed on the computer or other programmable apparatus to produce a computer implemented process such that the instructions which execute on the computer or other programmable apparatus provide steps for implementing the functions/acts specified in the flowchart and/or block diagram block or blocks.
With reference now to
A computer user may want to do more than maintain a personal blog focused on a favorite sports team or a favorite hobby. A sports fan may want to provide the latest scores or statistics for his team in a frame 18 on the personal home page screen or the most recent team press releases in another frame 20 in the personal home page.
While the user can obtain this kind of information via television or radio broadcasts or by web surfing and then key it in the system through keyboard 22, this approach requires a significant effort from the user as well as constant attention to the personal home page. It would be much easier for the user if the desired information could be acquired via the Internet 24 from one or more remote servers, represented in the drawing by remote server 26, on which the information is already made available to Internet users and then used to automatically (i.e., dynamically) update the personal home page without direct user involvement.
The personal computer system includes a system bus 30 used to interconnect elements of the infrastructure such as processor 32, random access memory (RAM), read only memory (ROM), high-capacity memory devices 38, examples of which are magnetic hard drives and/or optical CD or DVD drives, input/output adapters 40, network adapters 42 that provide the connection to the external video sources 28 through the Internet 24, and general use adapters 44 that can be used for a variety of purposes. Examples of general use adapters are USB or Firewall adapters that can be used to connect a variety of external devices, including but not limited to backup hard drives, fingerprint readers, printers, and wireless transceivers, etc., to the system bus 30 in the personal computer system.
In implementing the present invention, the personal computer system may also include dedicated video screen buffers 46 used to store video content captured or grabbed from specified external video sources 28. The role of the video screen buffers is described in greater detail below.
The present invention stems from a realization that useful content can be acquired from external sources via the Internet without the use of markup languages, source code or application programming interfaces (APIs) for the external sources. If the external source is represented as a video display on a computer display screen and if the content that is to be acquired always occupies the same region on that display screen, the content can be acquired by “grabbing” the screen image, designating the coordinates of the pixels that convey the desired content, storing those pixels in a video screen buffer and then writing them into a “hole” or region reserved in the personal home page for the external content.
As an example, assume the personal computer user is a New York Yankees fan who knows that the Yankees maintain a website with a home page configured for display at a resolution of 1024×768 pixels and that the screen always includes a rectangular frame that displays the scores of recently played games. By detecting the screen position of a cursor, the user can establish that the top left corner of the frame always appears at a pixel position of x=0, y=240 while the bottom right corner of the frame always appears at a pixel position of x=256, y=288.
Armed with this information, the personal computer user can configure the computer system to periodically acquire the web page including the desired scores, acquire the content bounded by pixel ranges 0≦x≦256 and 240≦y≦288, and write the content into an associated video buffer. The acquired content can then be used to refresh a dedicated region on the personal home page.
A user need not be limited to acquiring content from a single external source. Content from multiple sources can be obtained as long as the user knows the address of each source page and the pixel coordinates for the desired information on the source page. Moreover, it is not necessary that the acquired content occupy the same relative position on the target or personal home page that it occupies on the source page. All that is necessary is that the personal home page has a dedicated region associated with the external content to be displayed and that the dedicated region have the same horizontal and vertical pixel dimensions as the source frame for the content on the external source screen. That is, if the external source originally displays the content in a box 256 pixels wide and 48 pixels high, the personal home page must also have a region somewhere on the home page that is 256 pixels wide and 48 pixels high and is dedicated to displaying the desired content.
While the present invention is most likely to be implemented by programming a general-purpose computer, such as a personal computer, it can be implemented as a dedicated system comprising a combination of special-purpose hardware, firmware or microcode and perhaps conventional software.
The dedicated system 60 includes a system timer 62 for controlling the timing of operations, including the acquisition of the external content from external video sources 28. System timer 62 controls pixel acquisition logic 64 that is used to establish connections to the external video sources 28 through a network interface 66. The external content acquired from the external video sources 28 is retrieved through network interface 66 and sent to pixel processing logic 68 that isolates the desired content from the remainder of the external video screen and sends only the desired content to via screen buffers 70. The desired content is combined with other locally generated content in video driver 72 before being written to the monitor 12.
In order to operate properly, both a programmed general-purpose computer system and a dedicated system have to be configured. The configuration process is illustrated at a high level in a flowchart in
Once the external source is identified, the full network path to that source is established in step 78. The network path in most cases is likely to be a conventional URL or Universal Resource Locator.
After establishing the path to the external source, the pixel coordinates of the desired content on the source page are established in step 80. One simple way to establish the coordinates is for the system user to first position the cursor at the top left corner of the source frame having the desired content, perform a mouse click operation which can be translated into the x and y coordinates of the cursor position, move the cursor to the bottom right corner of the source frame and repeat the operation.
In the next step 82, a decision is made as to how frequently the personal home page is to be updated with information acquired from the external source; that is, what the source refresh interval is to be. In step 84, the pixel coordinates for the home page region at which the acquired content is to be displayed must be established by the user.
Once the preceding steps are completed, the network path, the source pixel coordinates, the home page pixel coordinates and the refresh interval are stored in the local system in a step 86. Following the storage step, a check is made in step 88 as to whether other additional external sources need to be configured. If there are more external sources to be configured, the program loops back to operation 76. If there are no additional external sources to be configured, the configuration process is terminated.
The above description assumes a “pull” model is used to control the dynamic update process in either a programmable general-purpose computer system or a dedicated system.
It will be noted that in the update process is shown as being performed on a source-by-source basis, which makes sense where different sources have different refresh intervals. System programming could be simplified somewhat if it were decided to have the same refresh interval for all external sources. In that case, the process described with reference to
In an alternate embodiment, the invention is implemented by using an external content server (not shown) to “push” source updates to the local system. The “push” model shown in
The retrieved coordinates are used to isolate the desired contents from the external source page before storing those contents in a screen buffer in step 116. The final step is to rewrite the personal home page with the newly acquired content in step 118.
