Description:
TECHNICAL FIELD  
         [0001]    The present disclosure relates to digital image distribution and display. More particularly, the disclosure relates to systems and methods for leasing digital images via a communications network.  
         BACKGROUND OF THE INVENTION  
         [0002]    In most urban centers, exposure to information such as advertising information and current news information has become an accepted part of everyday life. Apart from newspapers, magazines, and television, mass advertising information is visually presented by way of billboards, posters, and other various signs, which are capable of displaying relatively fixed images. Countless products and services are presented to the public via fixed images with limited text. In an effort to capture and hold public attention, some mass advertising has been presented via pixelboards containing an array of light emitting diodes and/or lamps that can be controlled over time to present simple animation, pictures, and updateable textual information. Recently, billboards capable of presenting a series of different fixed images have been used to advertise more than one product or service. Despite these advances, manufacturers, distributors, and advertisers are continuously seeking further advances in public image displays. In addition to efforts targeted to attract consumers, distributors seek further advances for maintaining and updating advertisements and other public displays.  
           [0003]    For example, operators of billboards maintain not only the support structure, but must identify a new client and create the appropriate sized image when a present client no longer wishes to display their particular advertisement on the board. After the image has been generated, technicians must visit the site to apply the new image. Similarly, each new graphic image, text message, or animation for a new client or message designated for a pixel board is programmed and the program delivered to the site of the pixelboard. By way of further example, in order to update and/or replace publicly displayed posters and placards, the replacements must be printed, distributed, and the various display sites visited in order to remove and replace the various advertisements.  
           [0004]    Recent advances in data storage capacity and data compression techniques, coupled with advances in the art of image display technology, have resulted in the proliferation of high-resolution television quality display devices. Nearly every major sporting and convention venue has one or more display devices suited for providing advertising, information updates, close-ups of the action or performance, replays, and/or other images. The viewing public has come to expect such high-resolution color displays. However, many of these public venue displays are quite complex and require a significant support operation requiring real-time human interaction and a significant amount of computing power to supply the updated information to the viewers.  
           [0005]    Other public display devices consist of television type display monitors associated with closed-circuit input feeds from within the public facility. These systems are well known and are relatively easy to operate. However, closed-circuit display systems still require a significant level of human interaction at the point of distribution.  
           [0006]    A number of much simpler public display devices have been attempted with various degrees of success. For example, in order to reach a captive audience several public display systems have been developed for use in public elevators. Display systems for these environments often attempt to provide real-time information pertinent to their captive audiences.  
           [0007]    To date, information display systems for elevators are capable of presenting at most the floor number, a floor directory of tenants and in some cases simple text based news information. For example, U.S. Pat. No. 4,995,479 to Fujiwara, appears to describe a display apparatus for an elevator in which information regarding the operating conditions of the elevator is displayed along with “general” information, such as news and weather. A display unit is provided within the elevator cab and includes a display area for displaying text along side a picture display area for displaying predetermined graphic images. Predetermined pieces of information are assembled and assigned a number indicative of a priority for that piece of information. The information is selected for display in accordance with the priority value associated with the information. The system described in the &#39;479 patent is not well suited for the presentation and leasing of advertisements as the messages are not easily updateable and information is restricted to basic text and primitive graphic data.  
           [0008]    U.S. Pat. No. 5,056,629 to Tsuji, et al., appears to describe another display apparatus capable of presenting news, weather, etc., to those in an elevator cab. The information is selected to be displayed at predetermined times. The device described in this patent allows for the information displayed to be corrected (i.e., new or replacement information displayed) through inputs made remotely from the elevator cab or from a caretaker&#39;s room via a portable computer. As with the &#39;479 patent, the &#39;629 patent discloses a simple scrolling message display system updateable via a remote computer. The device disclosed in the &#39;629 also requires extensive on-site user intervention to update the displayed messages.  
           [0009]    In U.S. Pat. No. 5,485,897 to Matsumoto, et al., an elevator display system is disclosed in which operational information concerning the elevator, in particular a floor indicator, is superimposed on a background image on a display screen. The background image is described as being a plurality of still pictures assigned to the different floors at which the elevator stops or different kinds of animations assigned to the different floors. As with the other display systems, the &#39;897 patent does not offer an easily updateable and controllable solution for advertisers interested in presenting their goods and services via public display systems.  
           [0010]    Other display systems are presently available commercially. For example, Ceiva Logic, Inc. of Los Angeles, Calif., has produced and marketed a digital picture frame. Ceiva&#39;s digital picture frame permits subscribers of their service to display digital pictures of family and friends, as well as, works of art.  
           [0011]    Using the Ceiva Gallery, Ceiva customers can also select specific digital images of famous works of art for display. In addition, Ceiva users have the capability to purchase prints from various art collections from the Cieva Internet site. Ceiva&#39;s system has several limitations that prohibit its use as a system and method for distributing and maintaining public service messages and advertisements for a fee. For example, Cieva&#39;s subscribers must directly select each individual image for display. While the Cieva Gallery permits access to multiple galleries or collections of art works, the user must actively select each image for download and display in accordance with the users&#39;s preferred display mode. In contrast, advertisers, politicians, and others that pay a fee for public displays and presentations of their goods, services, and messages desire control of the presentation method, the locations where their information is presented, and assurance that the images were presented.  
           [0012]    From the foregoing, it can be appreciated that it would be desirable to have a flexible system and method for conveniently delivering, presenting, and monitoring, publicly displayed digital images that avoids one or more of the problems and/or shortcomings identified above.  
         SUMMARY OF THE INVENTION  
         [0013]    Briefly described, in architecture, a digital image leasing system (DILS) capable of controllably distributing a plurality of digital images selected for presentation via a plurality of respective displays can be realized with one or more servers communicatively coupled via a communications network, and a plurality of identifiable and individually controllable display devices coupled to the one or more servers.  
           [0014]    Other embodiments of the DILS may be realized in methods for distributing and presenting preferred data from a host server to a display device through a communications network. A preferred method involves the steps of: (1) identifying a user preference, (2) providing at least one data feed containing information related to the user preference, (3) selecting preferred data from the data feed corresponding to the user preference, (4) pre-loading information that matches the preferred data from the host server to the display device, and (5) presenting the preferred data through the display device.

     DETAILED DESCRIPTION  
       [0025]    Based on the current state of the art regarding publicly-observable display systems, there is a need for a flexible and easily managed system for distributing and reliably displaying public service announcements and other images of a commercial and/or political nature, which provides for the remote and distributed coordination and dissemination of the information. A preferred embodiment of the present invention as described below provides a system that is site addressable with the potential for a single facility and/or areas within a facility to present its own unique sequence of images in accordance with its own display schedule. Furthermore, the present invention reduces the need to periodically remove and replace prior art posters, placards, and/other various signs commonly used to advertise and/or convey various messages in public venues. Moreover, the present invention can take advantage of display technology that presents multiple high quality images over time at refresh rate more in line with today&#39;s fast paced society.  
         [0026]    DILS—Architecture and Overview  
         [0027]    Referring now in more detail to the drawings, FIG. 1 is a schematic view illustrating various components of an exemplar digital image leasing system in accordance with one embodiment of the present invention. In this regard, the schematic illustrates that in a simple embodiment a digital image leasing system (DILS)  100  may comprise a control site  105  in communication with a service lessee (i.e., a customer) computing device  102  and various remote premises  140 ,  150 , and  160 .  
         [0028]    A service lessee may communicate with an application server  110  located within the control site  105  by using a suitably configured computing device  102  via a wide area network or local area network (WAN/LAN)  170 . In a preferred embodiment, WAN/LAN  170  comprises the public switched telephone network (PSTN) separately or in association with the publicly accessible WAN commonly known as the Internet.  
         [0029]    As illustrated, control site  105  may also comprise a database server  120  suitably configured to store client data  122  and image data  124 . In more robust embodiments, various routers and gateways configured with appropriate firewalls may be disposed to enable 24 hour controlled access for approved clients to the application server  110 . Consequently, any appropriately configured computing device in communication with WAN/LAN  170  can be used to initiate a service/client relationship via appropriately configured software resident and operable on the application server  110 . Furthermore, any appropriately configured computing device in communication with WAN/LAN  170  can be used to configure operation of various display devices  400  located at each of the remote premises  140 ,  150 ,  160 .  
         [0030]    In other more distributed embodiments, the application server  110  may be remotely located from the database server  120  with the application and database servers  110 ,  120  in communication via a proprietary LAN (not shown), a dedicated communication link (not shown), or other suitable communication link. In still other realizable embodiments, underlying application software may be provided by an application service provider (ASP) in communication with WAN/LAN  170  (not shown for simplicity of illustration) and/or the client database  122  and the image database  124  may be stored across one or more distinct servers (not shown).  
         [0031]    The flexibility inherent in the DILS  100  is illustrated in the various configurations realizable in each of the remote premises “A,” “B,” and “C”  140 ,  150 , and  160 , respectively. These exemplar configurations represent just some of the many configurations available for conveniently delivering, presenting, and monitoring, publicly displayed digital images consistent with the present invention. For example, remote-premise “A”  140  comprises a local computing device  130  and a plurality of display devices  400 . As depicted in the schematic of FIG. 1, the local computing device  130  may be configured with a radio frequency (RF) and/or an infrared (IR) transceiver for establishing a wireless communication link with suitably configured display devices  400 .  
         [0032]    In a second example, labeled, remote-premise “B”  150 , a site controller  152  may be provided to coordinate and control the operation of a plurality of suitably configured display devices  400 . As illustrated in FIG. 1, each of the plurality of display devices  400  may be in direct communication with the site controller  152  via various electrically coupled interfaces. For example, each of the display devices  400  may be configured with a modem for establishing periodic communication sessions with WAN/LAN  170  or the PSTN (not shown) via the site controller  152 . By way of further example, a plurality of closely located display devices  400  may be daisy-chained on a communications bus (not shown) to permit periodic communications sessions with control site  105  via the site controller  152  and WAN/LAN  170 .  
         [0033]    In alternative embodiments, the display devices  400  may be configured to interface with WAN/LAN  170  via wireless and wired interfaces other than the local computing device  130  and the site controller  152  illustrated at remote premise “A”  140  and remote premise “B,” respectively. Those skilled in the art are familiar with the use of universal asynchronous receiver-transmitters (UARTs) that enable serial communications between computing devices such as the service lessee&#39;s computing device  102 , application server  110 , local computing device  130 , and site controller  152  and peripheral devices such as the display devices  400 . UARTs are available commercially within standard integrated circuit packages. UARTs have also been implemented within application specific integrated circuits (ASICs) to reduce production costs of peripheral devices. Those skilled in the art are also familiar with integrating UARTs with both RF and IR devices to enable serial communications between remotely located devices, such as the display devices  400  and the local computing device  130 .  
         [0034]    RF and IR transmitters and receivers associated with the various display devices  400  of the DILS  100  are preferably small in size and may be configured to transmit a relatively low-power signal. As a result, in some applications, the transmission range of a given communication module associated with a particular display device  400  may be relatively limited. This relatively limited transmission range of the communication devices is an advantageous and desirable characteristic of the DILS  100  because it permits reuse of identifiers associated with each of the display devices  400  under the operation and control of the DILS  100 .  
         [0035]    Although each of the various display devices  400  is depicted without a user interface such as a keypad, in some embodiments the display devices  400  may be configured with user selectable pushbuttons, switches, or the like to permit a technician to configure the display. It should be appreciated that each of the display devices may be configured with a key, password, or other such mechanism to prevent unauthorized adjustments of the display device  400 .  
         [0036]    In preferred embodiments, once the client relationship is verified, the client or an agent of the client in communication with the application server  110  via local-computing device  130  or lessee computing device  102  may be presented with an interface reflective of a number of display options available from the provider. The display options may provide information regarding the location of available displays, various time slots available to present the client&#39;s messages or images, the size and quality of each of the various display devices  400  in the DILS  100 , the expected number of visitors at each of the display locations during particular times of day, and other information that the service may provide including rental rates and packages. The client, after having identified one or more display devices, time slots, and/or rental packages may begin to upload one or more digital images to the database server  120  to populate image data  124 . It should be appreciated that in alternative embodiments, a client may a priori populate image data  124  with one or more images.  
         [0037]    A third example for providing image data to a display device  400  is presented in the schematic illustrated in FIG. 1. In this embodiment, remote premise “C”  160  may comprise a display device  400  configured to receive a removable storage device  165 . Removable storage device  165  may take many forms. A number of proprietary data storage devices are presently commercially available. For example, CompactFlash® memory, a solid state memory cartridge sold blank or carrying data-compression software produced by Sandisk Corporation of Santa Clara, Calif. is an exemplar solution for delivering image data to a suitably configured display device  165 . The Sony Corporation of Tokyo, Japan also produces and distributes a small portable data storage device Sony deems the Memory Stick®. These and other devices may be used to realize the removable storage device  165  of FIG. 1.  
         [0038]    Removable storage device  165  may contain a digital representation of one or more digital images. Those skilled in the art will appreciate that the data representations may be compressed by any of a number of data compression methods. For example, the data representations or files may be compressed using a standard compression technique promulgated by the Joint Photographic Experts Group (JPEG). JPEG is a lossy data compression technique that allows operators to trade image quality for image size.  
         [0039]    Display device  400  may be configured to initiate a self-directed initialization or configuration mode upon detecting the placement of the removable storage device  165 . For example, upon the detection of the insertion or other association of a removable storage device  165  with the display device  400 , the display device  400  may perform a read operation of the memory stored within the removable storage device  165 . Firmware, software, and or hardware within the display device  400  may be configured to execute instructions formulated to compare the contents within the removable storage device  165  and to verify capacity and compatibility with the internal storage and operation of the display device  400 . In alternative configurations, the display device  400  may be configured to purge presently stored images from its internal memory and attempt to read and store the image data from the removable storage device  165 . In this way, an operator or employee of the service may be directed to shuttle an appropriately configured removable storage device  165  containing one or images designated for display at a particular site from the control site  105  to the remote premise “C”  160 .  
         [0040]    The DILS  100  of the present invention is not limited to the particular embodiments illustrated and described in association with FIG. 1. While the DILS  100  has been illustrated and described with regard to the exemplar remote premise configurations and the site controller configurations illustrated in the schematic of FIG. 1, those skilled in the art will readily recognize a plethora of remote premise configurations and site controller configurations consistent with the teachings of the present invention. For example, a remote premise (not shown) may comprise a combination of several different wireless, wired, and removable data storage interfaces.  
         [0041]    Reference is now directed to FIG. 2, which presents a functional block diagram of a local computing device and/or a service lessee&#39;s computing device of FIG. 1. In this regard, the lessee&#39;s computing device  102  and the remote-computing device  130  may be very similar devices.  
         [0042]    Generally, in terms of hardware architecture, as shown in FIG. 2, the computing devices  102 ,  130  may include a processor  210 , memory  220 , and one or more I/O interfaces in the form of human/machine interfaces  214 , WAN/LAN interfaces  215 , and IR/RF (i.e., wireless) interfaces  216  (or peripheral interfaces) that are communicatively coupled via local interface  212 . The local interface  212  can be, for example but not limited to, one or more buses or other wired or wireless connections, as is known in the art. The local interface  212  may have additional elements, which are omitted for simplicity, such as controllers, buffers (caches), drivers, repeaters, and receivers, to enable communications. Further, the local interface may include address, control, and/or data connections to enable appropriate communications among the aforementioned components.  
         [0043]    The processor  210  is a hardware device for executing software that can be stored in memory  220 . The processor  210  can be any custom made or commercially available processor, a central processing unit (CPU) or an auxiliary processor among several processors associated with the computing devices  102 ,  130 , and a semiconductor based microprocessor (in the form of a microchip) or a macroprocessor. Examples of suitable commercially available microprocessors are as follows: a PA-RISC® series microprocessor from Hewlett-Packard Company, an 80x86 or Pentium® series microprocessor from Intel Corporation, a PowerPC® microprocessor from IBM, a Sparc® microprocessor from Sun Microsystems, Inc, or a 68xxx® series microprocessor from Motorola Corporation.  
         [0044]    The memory  220  can include any one or combination of volatile memory elements (e.g., random access memory (RAM, such as dynamic RAM or DRAM, static RAM or SRAM, etc.)) and nonvolatile memory elements (e.g. read only memory (ROM), hard drives, tape drives, compact discs (CD-ROM), etc.). Moreover, the memory  220  may incorporate electronic, magnetic, optical, and/or other types of storage media. Note that the memory  220  can have a distributed architecture, where various components are situated remote from one another, but can be accessed by the processor  210 .  
         [0045]    The software in memory  220  may include one or more separate programs, each of which comprises an ordered listing of executable instructions for implementing logical functions. In the example of FIG. 2, the software in the memory  220  includes various applications  224  that function as a result of and in accordance with a suitable operating system  222 . A non-exhaustive list of examples of suitable commercially available operating systems  222  is as follows: a Windows® operating system from Microsoft Corporation, a Netware® operating system available from Novell, Inc., or a UNIX operating system, which is available for purchase from many vendors, such as Hewlett-Packard Company and Sun Microsystems, Inc. The operating system  222  essentially controls the execution of other computer programs, such as applications  224 , and provides scheduling, input-output control, file and data management, memory management, and communication control and related services.  
         [0046]    The applications  224  are source programs, executable programs (object code), scripts, or other collections each comprising a set of instructions to be performed. When in the form of a source program the program needs to be translated via a compiler, assembler, interpreter, or the like, which may or may not be included within the memory  220 , so as to operate properly in connection with the operating system  222 . Furthermore, the various applications  224  can be written in an (a) object-oriented programming language, which has classes of data and methods, or in a (b) procedure programming language, which has routines, subroutines, and/or functions. The various applications  224  may be written in a number of programming languages, for example but not limited to, C, C++, Pascal, Basic, Fortran, Cobol, Perl, Java, and Ada.  
         [0047]    The human/machine interfaces  214  may include input devices, such as but not limited to, a keyboard, a mouse or other suitable pointing device, a scanner, a microphone, etc. Furthermore, the human/machine interfaces  214  may also include output devices, for example but not limited to, a printer, a monitor, an external speaker, etc.  
         [0048]    WAN/LAN interfaces  215  may include a host of devices that may establish one or more communication sessions between the computing devices  102 ,  130  and WAN/LAN  170  (FIG. 1). WAN/LAN interfaces  215  may include but are not limited to, a modulator/demodulator or modem (for accessing another device, system, or network); a radio frequency (RF) or other transceiver; a telephonic interface; a bridge; a router; etc. For simplicity of illustration these aforementioned two-way communication devices are not illustrated.  
         [0049]    If the computing devices  102 ,  130  take the form of personal computers, workstations, laptop computers, or the like, the software in the memory  220  may further include a basic input output system (BIOS) (also omitted for simplicity of illustration). The BIOS is a set of essential software routines that initialize and test hardware at startup, start the operating system  222 , and support the transfer of data among the hardware devices. The BIOS is stored in a ROM so that the BIOS can be executed when the computing devices  102 ,  130  are activated.  
         [0050]    When the computing devices  102 ,  130  are in operation, the processor  210  is configured to execute software stored within the memory  220 , to communicate data to and from the memory  220 , and to generally control operations of the computing devices  102 ,  130  pursuant to the software. The various applications  224  and the operating system  222 , in whole or in part, but typically the latter, are read by the processor  210 , perhaps buffered within the processor  210 , and then executed.  
         [0051]    The various applications  224  can be stored on any computer readable medium for use by or in connection with any computer-related system or method. In the context of this document, a computer readable medium is an electronic, magnetic, optical, or other physical device or means that can contain or store a computer program for use by or in connection with a computer related system or method. The various applications  224  can be embodied in any computer-readable medium for use by or in connection with an instruction execution system, apparatus, or device, such as a computer-based system, processor-containing system, or other system that can fetch the instructions from the instruction execution system, apparatus, or device and execute the instructions.  
         [0052]    In the context of this disclosure, a “computer-readable medium” can be any means that can store, communicate, propagate, or transport a program for use by or in connection with the instruction execution system, apparatus, or device. The computer readable medium can 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 (electronic) having one or more wires, a portable computer diskette (magnetic), a random access memory (RAM) (electronic), a read-only memory (ROM) (electronic), an erasable programmable read-only memory (EPROM, EEPROM, or Flash memory) (electronic), an optical fiber (optical), and a portable compact disc read-only memory (CD-ROM) (optical). Note that the 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.  
         [0053]    As illustrated in FIG. 2, the computing devices  102 ,  130  may be configured with an IR/RF (i.e., wireless) interface  215  suited to transmit and receive data from a compatibly configured remote device such as the display devices  400  of FIG. 1. Whatever the nature of the IR/RF interface  215 , the wireless communication link formed supports the transfer of multiple digital images to compatibly configured display devices  400 .  
         [0054]    Site Controller—Architecture and Overview  
         [0055]    Reference is now directed to FIG. 3, which presents a functional block diagram of the site controller  152  of FIG. 1. Those skilled in the art will appreciate that the site controller  152  may be a less-robust device than the computing devices  102 ,  110 , and  130  described above as the site controller  152  will generally only be responsible for coordinating image and instructional data transfers. In this regard, the site controller  152  may comprise an application specific integrated circuit (ASIC)  310 , an EPROM  320 , RAM  322 , WAN/LAN interface  315 , and display device interface  317 . As illustrated in the schematic of FIG. 3, each of the component parts may be in communication with each other via local interface  312 .  
         [0056]    The local interface  312  can be, for example but not limited to, one or more buses or other wired or wireless connections, as is known in the art. The local interface  312  may have additional elements, which are omitted for simplicity, such as controllers, buffers (caches), drivers, repeaters, and receivers, to enable communications. Further, the local interface may include address, control, and/or data connections to enable appropriate communications among the aforementioned components.  
         [0057]    WAN/LAN interfaces  315  may include a host of devices that may establish one or more communication sessions between the site controller  152  and the various computing devices  102 ,  110 ,  130  (and others) in communication with WAN/LAN  170  (FIG. 1). WAN/LAN interfaces  315  may include but are not limited to, a modulator/demodulator or modem; for accessing another device, system, or network); a radio frequency (RF) or other transceiver; a telephonic interface; a bridge; a router; etc. For simplicity of illustration these aforementioned two-way communication devices are not illustrated.  
         [0058]    ASIC  310  may be implemented with combinational logic gates, a programmable gate array(s) (PGA), a field programmable gate array (FPGA), etc. The various sub-components (e.g., the logic gates or gate arrays), of ASIC  310  may be arranged to permit the site controller  152  to distribute various control information and image data to each of a plurality of display devices  400  via one or more communication links. EPROM  320  may include identification information associated with a particular site controller  152 , as well as identification and configuration information related to each display device  400  designated for operation at a particular premise via the site controller  152 . RAM  322  may be provided for the temporary storage of image data, or configuration information designated for each of the display devices  400 . RAM  322  may be necessary in order to buffer data received from one or more display devices for situations where the data transfer rate between the site controller  152  and the application server  110  via WAN/LAN  170  differs from the data transfer rate between the site controller  152  and each of the associated display devices  400 .  
         [0059]    As illustrated in FIG. 3, the site controller  152  may be configured with a display device interface  317 . Those skilled in the art will appreciate that the display device interface  317  may take several different forms. For example the interface may take the form of a serial controller electrically coupled to one or more wires further coupled to one or more display devices  400 . In alternative embodiments, the display device interfaces  317  may take the form of an IR/RF (i.e., wireless) interface suited to transmit and receive data from a compatibly configured remote device within the display devices  400 . Whatever the nature of the display device interface  317 , the communication link formed supports the transfer of multiple digital images to compatibly configured display devices  400 .  
         [0060]    The software in EPROM  320  may include one or more separate programs, each of which comprises an ordered listing of executable instructions for implementing logical functions. In the example of FIG. 3, the software in EPROM  320  may include functionality for receiving images and instructional data from the application server  110 . In this regard, the EPROM  320  may include instructions for scheduling, input-output control, file and data management, memory management, and communication control and related services.  
         [0061]    Once a communication link has been established between the site controller  152  and the application server  110  via WAN/LAN  170  (FIG. 1), the received images and instructional data may be directed to RAM  322  for temporary buffering until a communication link is established with the designated display device  400 . Once a communication link is established between the designated display device  400  and the site controller  152 , any instructions and image data updates for the display device  400  may be transferred from the site controller  152  to the display device  400 .  
         [0062]    Either the display device  400  or the site controller  152  may be configured to initiate a communication session between the two devices. Under some circumstances, the display device  400  may initiate the communication session. For example, the display device  400  may initiate a communication session to report one or more adverse conditions detected during a periodic health status check. Under other circumstances, the site controller  152  may initiate a communication session. These circumstances may include site or premise-wide instructions designated for a plurality of display devices  400  where the site controller  152  may have circuitry resources capable of communicating with a limited number of display devices  400  at any given time.  
         [0063]    In some embodiments the site controller  152  may be configured with an interface suited to receive instructions from a technician. In these embodiments, the site controller  152  may include a display panel or other visual means (not illustrated) for prompting and/or providing feedback to the technician. The site controller  152  may also contain a plurality of inputs (not shown) suited to receive command inputs from the technician. It will be appreciated that these embodiments of the site controller  152  may also be associated with appropriate hardware, firmware and/or software to support these interfaces. It should be further appreciated that the site controller  152  may be configured with an operating system, such as but not limited to, Windows CE® for use with computer programs for managing communications and data exchange between handheld and/or remote computing devices and desktop computers. (Windows CE® is a registered trademark of the Microsoft Corporation of Redmond, Wash.)  
         [0064]    When the site controller  152  is in operation, the ASIC  310  is configured to execute software/instructions stored within the EPROM  320  and/or RAM  322  to communicate data to and from display devices  400 . The various instructions and the operating system where appropriate, in whole or in part, but typically the latter, are read by ASIC  310 , perhaps buffered within the ASIC  310 , and then executed.  
         [0065]    As in the case of the various computing devices described above with regard to the functional block diagram of FIG. 2, the various instructions and/or operating system associated with the site controller  152  of FIG. 3 can be stored on any computer readable medium for use by or in connection with any computer-related system or method. Accordingly, more advanced versions of the site controller  152  may include one or more data storage and transfer devices suitable for interfacing with a computer readable medium as described above.  
         [0066]    Display Devices—Architecture and Overview  
         [0067]    Referring now to FIG. 4, the display device  400  may include a micro-controller  410 , a power supply  420 , a display driver  430 , and display  440 . As illustrated in the schematic of FIG. 4, the micro-controller  410  may be in communication with an Electrically Erasable Programmable Read-Only Memory (EEPROM)  412 , transceiver  414 , storage port  416 , and RAM  418 .  
         [0068]    As illustrated in the functional block diagram of FIG. 4, power supply  420  may provide power to both the micro-controller  410  and the display driver  430 . In addition to receiving power from power supply  420 , the micro-controller  410  may receive data instructions via a removable storage device  165  in cooperation with storage port  416 , as well as, EEPROM  412  and/or transceiver  414 . In addition to receiving data instructions, the micro-controller  410  may also be configured to receive image data from a removable storage device  165  in cooperation with storage port  416  and/or transceiver  414 . Image data received by the micro-controller  410  may then be forwarded to RAM  418  where it may be stored until such time that the microcontroller  410  instructs that the image data should be forwarded via the display driver  430  for presentation via display  440 .  
         [0069]    EEPROM  412  may include instructions for controlling transceiver  414 , storage port  416 , and for operating display  440 . It will be appreciated that micro-controller  410  may receive and process instructions designed to modify the operation of display device  400 . For example, EEPROM  412  may include instructions regarding the number of images to display, how long to display each image in RAM  418 , how frequently to establish a communications link with site controller  105 , etc. These instructions may be received via a removable storage device  165  in association with storage port  416 , transceiver  414 , and/or other suitably configured interfaces (not shown). The instructions may then be written to EEPROM  412  in accordance with suitable instructions received from the micro-controller  410 .  
         [0070]    The embodiment illustrated in the functional block diagram of FIG. 4 is not intended nor should be construed to limit the scope of the present invention to such a display device  400 . For example, display device  400  may include other ports for receiving and transmitting information regarding display health. The display device may include other forms of ROM in addition or instead of EEPROM  412 .  
         [0071]    DILS—Operation  
         [0072]    Reference is now made to the flow chart illustrated in FIG. 5, which presents a method for distributing and presenting preferred data (i.e., image data identified by an operator of a lessee computing device  102 ) from a host server (i.e., application server  110 ) to a display device  400  through a communications network (e.g, WAN/LAN  170 ). A preferred method  500  may begin with step  502 , where, as illustrated, a client of the DILS  100  of FIG. 1) may identify one or more preferences for publicly displaying one or more messages or images. Next, in step  504 , the client communicates the one or more preferences identified in step  502  to an operator of the DILS  100 . The client may also transfer a plurality of digital images to an operator of the DILS  100  for the subsequent transfer to a plurality of remote display devices  400 .  
         [0073]    An operator of the DILS  100  (FIG. 1), as illustrated in step  506 , may respond by identifying and/or selecting one or more digital images that meet the preferred criteria communicated by the client. Next, as illustrated in step  508  an application server  110  (FIG. 1) may configure one or more database records in anticipation of initializing a communication link between the control site  105  and one or more local computing devices  130 , site controllers  152 , and/or display devices  400  directly. Regardless of the device initiating the communication link, once a communication link is established, the method  500  may perform step  510  where a display device  400  is configured to display one or more images designated for the particular display device  400 .  
         [0074]    Reference is now directed to the flow chart illustrated in FIG. 6, which presents a method for operating a service that displays digital images for a fee that may be practiced by the DILS of FIG. 1. As illustrated in FIG. 6, a proprietor of the method  600  may begin with step  602  by assembling and indexing a plurality of digital images. It should be appreciated that the proprietor may collect and index images that the proprietor may offer as backgrounds for public service messages, political messages, and/or commercial advertising. Alternatively, and/or concurrently the proprietor of the method  600  may be prepared to receive and store digital representations of similar materials provided by clients of the service.  
         [0075]    As shown in step  604 , the proprietor may be prepared to collect and store client identification and billing information. The proprietor, having identified clients in step  604 , may then be prepared to associate one or more display devices  400  (FIG. 1) with each client of the service as illustrated in step  606 . After associating one or more clients of the service with each particular display device  400  in step  606 , the proprietor of the method  600  may prepare one or more databases and/or one or more database records in accordance with the various information collected regarding the client, client preferences, select display devices  400 , and various information regarding a desired configuration of the display device  400 , display frequency, display rates, etc.  
         [0076]    Next, as illustrated in step  610 , the proprietor may provide a mechanism for communicating the information collected in step  606  to each identified display device  400  that a client has indicated that they would like to present their preferred images. The communication session may result in the transfer of client configuration preferences for the display device  400 , the images designated for display, time slots designated for presenting particular images, etc. Finally, the proprietor of the method for operating a service that displays digital images  600  may issue periodic billing statements to the clients. It will be appreciated that a proprietor of such a system may also be prepared to collect, monitor, or otherwise process client payments received in response to the periodic billing statements.  
         [0077]    Reference is now directed to the flow chart of FIG. 7. The flow chart presents a method for updating  700  the display device  400  of FIG. 4. The method  700  may begin with step  702  where a communication session is initiated with an image service server (i. e., applications server  110 ). Once the communication session has commenced, the display device  400  may be configured to transfer one or more identifiers associated with the particular display device  400 . The display device  400  may also be configured to transmit an indication of the relative health of the display device  400 . Next, as indicated by the query of step  706  a determination may be made by the applications server  110  as to whether new images and/or configuration information is designated for the particular display device  400 . When the response to the query of step  706  is affirmative, i.e., configuration information and/or new images are designated for the display device  400 , the display device  400  may be configured to receive the appropriate data as indicated in step  708 .  
         [0078]    As illustrated in step  710 , a counter may be incremented in order to track the number of images transferred to the display device  400 . As indicated by the flow control arrow exiting step  710 , steps  706  through  710  may be repeated as necessary until the display device  400  has received each of the images designated for storage and periodic presentation by the display device  400 . Otherwise, when the response to the query of step  706  is negative, the display device  400  may be configured to terminate the communication session with the application server  110  as illustrated in step  712 . Once the communication session is terminated, the display device  400  may be configured to enter a display mode as indicated in step  714 .  
         [0079]    Reference is now directed to the flow chart of FIG. 8. In this regard, the flow chart presents a method for operating  800  the display device  400  of FIG. 4. The method  800  may begin with step  802  where the display device  400  reads the number of images to display, an indication of how long each of the images received is to be presented on the display device  400 . As further illustrated in step  802 , the display device  400  may receive an indicator of when the display device  400  should attempt to establish a communication session with the application server  110  (FIG. 1). Next, as indicated in step  804  a counter may be initialized.  
         [0080]    The display device  400  may be configured to process a first image from RAM  418  (FIG. 4). After having read a first image from RAM  418  and having decompressed or otherwise translated the image data, the display device  400  may present the image on display  440  (FIG. 4) and start a timer as indicated in step  808 . The display device  400  may be configured to perform the query of step  810  in order to determine if the presently displayed image&#39;s designated time for presentation has elapsed. When the result of the query of step  810  is negative, the display device  400  may be configured to repeat step  810  until the presently displayed image has been presented on the display for the agreed upon time period.  
         [0081]    Otherwise, when the query of step  810  results in an affirmative response, i.e., the designated time for display of the present image has elapsed, the display device  400  may be configured to increment the counter initialized in step  804  as illustrated in step  812 . Next, as illustrated in step  814 , the display device  400  may be configured to query whether the present time is equal to the next prompt time (i.e., a designated time to attempt to establish a communication link with the application server  110  of FIG. 1). When the response to the query of step  814  is negative, i. e., the display device is to remain in an operation or presentation mode the display device  400  may be configured to repeat steps  806  through  814 .  
         [0082]    Otherwise, when the response to the query of  814  is affirmative, i.e., it is time for the display device to be updated, the display device  400  may be configured to initiate a communication session with the application server  110  (FIG. 1). As further illustrated in the flow chart of FIG. 8, the display device  400  may repeat steps  802  through  816  as previously described.  
         [0083]    Any process descriptions or blocks in the flow charts of FIGS.  6 - 8  should be understood as representing modules, segments, or portions of code which include one or more executable instructions for implementing specific logical functions or steps in the methods presented. Alternate implementations are included within the scope of the preferred embodiments of the DILS  100  in which functions may be executed out of order from that shown or discussed, including substantially concurrently or in reverse order, depending on the functionality involved, as would be understood by those reasonably skilled in the art of the present invention.  
         [0084]    It should be emphasized that the above embodiments of the DILs, particularly any preferred embodiments, are merely possible examples of implementations and are set forth for a clear understanding of the principles involved for distributing and presenting preferred image data via a network for a fee.
