     FIELD OF INVENTION 
       [0002]    The present invention relates to an apparatus and method to communicate multimedia documents or content to a mobile or fixed device over a wireless network. In particular, the mobile or fixed device may be configured as a digital periodical or advertising device to transmit and receive converted multimedia documents or content delivered using multimedia messaging service over a wireless network. 
       BACKGROUND 
       [0003]    Wireless communications has enabled widespread easy access to mass media and multimedia information via mobile devices, cellular phones, personal digital assistants, smart phones, or the like. Although the availability of multimedia information is ubiquitous, proper viewing, display, and delivery of information for an enjoyable user experience is still lacking. This is especially the case for viewing periodicals such as online magazines or news content on a mobile device where a large display is desirable. Moreover, having complex software and hardware is required to receive and display multimedia periodical information on present mobile devices making them expensive, heavy, and power intensive. 
         [0004]    Digital fixed advertising display systems are commonplace in urban environments. However, widespread use of these systems is not commonplace since they require a fixed power source and wired network connection. This is problematic for rural and remote locations such as highways and light or utility posts where access to power and communications infrastructure is limited. Moreover, digital advertising systems do not provide any interactivity, location awareness, or accessibility to Internet content making them poor for creating impressions on consumers and constraining their effectiveness. 
         [0005]    Organic light emitting diode (OLED), liquid crystal display (LCD) flexible device technology, and other flexible substrate technologies have made advancements recently promising to provide an enhanced user experience, larger display sizes, portability, and low power consumption. However, commercialization of products having flexible displays has been slow due to a lack of viable and robust consumer applications. Moreover, another problem with devices having flexible displays is the ability to integrate other electronic circuitry due to form factor constraints and poor design. 
         [0006]    Multimedia Messaging Service (MMS) is a standardized technology being developed by the Third Generation Partnership Project (3GPP), the Third Generation Partnership Project 2 (3GPP2), and the Open Mobile Alliance (OMA). Although originally developed to send photos and simple video clips, recently added features to MMS have expanded its capabilities. The added features to MMS have made it into the preferable transport and presentation mechanism of mobile messaging that rivals electronic mail. However, the commercial applications and utilization of advanced MMS features has been limited. It is desirable to provide a digital periodical or advertising device preferably having a flexible display for receiving diverse mass media information, multimedia information, or Internet content in an efficient manner using MMS. 
       SUMMARY 
       [0007]    An apparatus and method for delivering mass media and multimedia information to a digital periodical or advertising device preferably using Multimedia Messaging Service (MMS) and having an electronic flexible screen or display is disclosed. A multimedia document, part of a multimedia document, web page, multimedia advertisement, or any other multimedia content on a server or a computer is extracted, parsed, and/or segmented into a plurality of video, audio, image, or text elements. The plurality of elements are each converted to an MMS message and transmitted optionally with an MMS assembler message or embedded information in each MMS message for proper reassembly of the original multimedia document or content. The MMS messages are received and reassembled back into the original multimedia document or content at a digital periodical or advertising device.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
       [0014]    The present invention will be described with reference to the drawing figures wherein like numerals represent like elements throughout.  FIG. 1  is a diagram of a digital periodical or advertising device  100  for mobile or fixed applications. Mobile applications include a digital newspaper, magazine, brochure, or any other digital mass media medium or apparatus. Fixed applications include a digital billboard, flyer or any other advertising medium or apparatus. 
         [0015]    Device  100  comprises computer bus  140  that couples one or more processors  102 , interface controller  104 , memory  106  having software  108 , storage device  110 , power source  112 , display controller  120 , one or more displays  122 , such as flexible organic light emitting diode (OLED) electronic displays, input/output (I/O) controller  116 , I/O devices  118 , GPS device  114 , one or more network adapters  128 , and one or more antennas  130 . Device  100  may optionally have one or more motion, light, heat, radio frequency identification (RFID), face recognition, shape, or voice recognition sensors  126  and touch detector  124  for detecting any touch inputs, including multi-touch inputs, for one or more displays  122 . Interface controller  104  communicates with touch detector  124  and I/O controller  116  for determining user inputs to device  100 . Storage device  110  may be any disk based or solid state memory device for storing data. Power source  112  may be a battery, solar panels for receiving and storing solar energy, or a device for receiving and storing wireless power as described in U.S. Pat. No. 7,027,311 herein incorporated by reference as if fully set forth. 
         [0016]    In device  100 , one or more network adapters  128  may be configured as a Time Division Multiple Access (TDMA), Code Division Multiple Access (CDMA), Orthogonal Frequency-Division Multiplexing (OFDM), Orthogonal Frequency-Division Multiple Access (OFDMA), Global System for Mobile (GSM) communications, Enhanced Data rates for GSM Evolution (EDGE), General Packet Radio Service (GPRS), cdma2000, Wideband CDMA (W-CDMA), Long Term Evolution (LTE), 802.11x, Wi-Max, mobile Wi-MAX, or any other wireless or wired transceiver for modulating and demodulating information communicated via one or more antennas  130 . 
         [0017]    In one embodiment of the present invention, one or more network adapters  128  are configured to only handle data traffic thereby eliminating the need for circuitry and software for handling voice traffic. This is advantageous as the circuitry for handling and processing voice traffic in mobile devices occupies substantial space, adds complexity, and results in unneeded cost for a digital periodical device where voice capability may be unnecessary. 
         [0018]      FIG. 2  is a diagram of a digital periodical or advertising device  200  having one or more electronic flexible screen or display devices  202 . The one or more electronic flexible screen or display devices  202  may be configured, manufactured, produced, or assembled based on the descriptions provided in U.S. Patent Publication Nos. 2007-247422, 2007-139391, 2007-085838, or 2006-096392 or U.S. Pat. No. 7,050,835 or WO Publication No. 2007-012899 all herein incorporated by reference as if fully set forth. The one or more electronic flexible screen or display devices  202  may be configured and assembled using organic light emitting diodes (OLED), liquid crystal displays using flexible substrate technology, flexible transistors, field emission displays (FED) using flexible substrate technology, as desired. In the case for multiple electronic flexible screens or display devices  202 , rotation  214  reveals a second electronic flexible screen or display device  203  on the back of device  200 . 
         [0019]    Any one of housing members  204  and  206  selectively house certain hardware components described in device  100  such as one or more processors  102 , memory  106 , one or more sensors  126 , and one or more network adapters  128 . In one embodiment of the invention, housing members  204  and  206  may each have individual transmitting/receiving antennas  216  and  218  for providing spatial and time diversity. One or more electronic flexible screen or display devices  202  can optionally be configured to collapse  208  and roll up into housing members  204  or  206  for portability. For orientating device  200  in a circular manner for a presentation or posting on a lightpost as an advertisement, attachment members  210  and  212  may be used. Housing members  204  and  206  may be rectangular or cylindrical and provide grasping positions, the ability to position device  200  upright on a flat surface, or the ability to mount device  200  on a flat surface, as desired. It is appreciated by one skilled in the art that housing members  204  and  206  and one or more electronic flexible screen or display devices  202  are not drawn to scale. They may have different shapes and dimensions while configured to provide the same functionality provided herewith. 
         [0020]    Still referring to  FIG. 2 , in another embodiment device  200  may optionally have a liquid crystal display (LCD), LED, FED, or OLED display unit  220 . For this case, when one or more electronic flexible screen or display devices  202  is collapsed into housing member  206  adjacent display unit  220  is still available for displaying content. When one or more electronic flexible screen or display devices  202  is expanded out of housing member  204  or  206 , the combination of display unit  220  and flexible screen or display devices  202  provides a larger screen size for a single graphical feed or for having separate graphical feeds or windows in each display unit, as desired. In this configuration, the images displayed on flexible screen or display devices  202  can be responsive to one or more sensors  126  detecting a bending of flexible screen or display devices  202 . 
         [0021]      FIG. 3  is a diagram of a system for providing and communicating mass media documents, multimedia documents, or any multimedia content in accordance with an embodiment of the present invention. Server or computer  300  may be configured as a web server, a multimedia messaging service center (MMSC), an MMS relay server, or a personal computer, as desired. Server or computer  300  at least comprises memory  302  coupled to one or more processors  310 , one or more network adapters  312 , and wireless power transmitter  320  via computer bus  305 . One or more network adapters  312  may be configured to implement any one of wireless or wired technologies given above. Wireless power transmitter  320  may be configured to provide power to device  318  as described in U.S. Pat. No. 7,027,311 herein incorporated by reference as if fully set forth. 
         [0022]    Memory  302  comprises a converter engine  304  having documents or content  306  and  308  that may be in a Microsoft WORD format, a Microsoft EXCEL format including graphs, a Portable Document Format (PDF), a PDF document having embedded multimedia advertisements including video and audio, an update for a PDF document previously transmitted for updating embedded multimedia advertisements including video and audio, a Hypertext Markup Language (HTML) format, a Microsoft PowerPoint presentation format, a digital multimedia periodical document, a digital periodical document having embedded multimedia advertisements, a digital advertising format, part of a digital advertising format, a selected subset of a multimedia document or the like having multimedia information. Converter engine  304  extracts, parses, and/or segments document  306  by detecting one or more video elements  306   1 , one or more audio elements  306   2 , one or more image elements  306   3 , or one or more text elements  306   4 . The video elements  306   1  may be flash video, shockwave video, MPEG video, streaming video, Advanced Video Coding (AVC), H.264 video, or the like. The audio elements  306   2  may be an MP3, WAV, Advanced Audio Coding (AAC), streaming audio, or the like. The image elements  306   3  may be JPEG, TIFF, bitmap, or the like. 
         [0023]    One or more text elements  306   4  may represent the body of document  306  that is divided into multiple parts. Any one of elements  306   1 - 306   4  may also represent dynamic advertising information, such as video or audio, that is embedded into document  306 . The dynamic advertising information may be updated based on user preferences, a target audience, location, or the like. In an embodiment of the present invention, document  306  is a PDF document and elements  306   1 - 306   4  sent via MMS are updates to multimedia advertising preexisting in the PDF document that are PUSHED to user agent  316  by computer or server  300 . 
         [0024]    Multimedia Messaging Service (MMS) is capable of communicating at least the following types of content:
       1. Short Message Service (SMS) types;   2. plain text;   3. speech;   4. audio;   5. synthetic audio, such as Scalable Polyphony MIDI;   6. still images, such as JPEG;   7. bitmap graphics;   8. video, including streaming video;   9. vector graphics, such as Scalable Vector Graphics (SVG), Tiny 1.2, or ECMAScript;   10. File Format for dynamic media;   11. Media synchronization and presentation format;   12. Digital Rights Management (DRM) format; and   13. Extensible Markup Language (XML).
 
Depending on the content of document  306 , elements in addition to  306   1  to  306   4  may be formed based on the types supported above by MMS. Once document  306  is extracted, parsed, and/or segmented into the appropriate number of elements representing its contents, each element  306   1  to  306   4  is converted into individual MMS messages with the recipient address of MMS user agent  316  by converter engine  304 . Elements  306   1  to  306   4  are then transmitted over network  314  as individual MMS messages to device  318  having MMS user agent  316 . Device  318  may be configured as device  100  or  200 , as desired. MMS user agent  316 , which may be executed by software running on one or more processors  102 , reassembles document  306  using elements  306   1  to  306   4  received as individual MMS messages.
       
 
         [0038]    Reassembly may be performed selectively by loading different parts of document  306  as the individual MMS messages are received by device  318 . Moreover, an MMS assembler message may optionally be transmitted by server or computer  300  having information required to properly reassemble elements  306   1  to  306   4  back into document or content  306 . The assembler may be an individual Synchronized Multimedia Integration Language (SMIL) or Wireless Markup Language (WML) message that coordinates and explains the relationship between elements  306   1  to  306   4  so that it can be reassembled back into document or content  306 . Alternatively, each MMS message is embedded with individual information, such as SMIL or WML language, describing the correct positioning or placement, including page number in the case of a multi-page document, and relationship to other elements within document or content  306  to display the delivered information. In an embodiment of the present invention, each received element received by device  318  may be positioned on one or more display devices  122  or  202  based on the physical position and viewing angle of one or more users detected by one or more sensors  126 . 
         [0039]    Still referring to  FIG. 3 , in one embodiment of the present invention elements  306   1  to  306   4  may delivered over network  314  using an Internet Protocol (IP) Multimedia Subsystem (IMS). Using IMS, the elements  306   1  to  306   4  may be packetized into IP packets by converter engine  304  so that they bypass routing through an MMSC and delivered directly to MMS user agent  316 . For the case where MMS user agent  316  is in a mobile phone configured for end-to-end IP communication, elements  306   1  to  306   4  may be routed using an IP address included in each MMS message rather an International Mobile Subscriber Identity (IMSI). 
         [0040]      FIG. 4  is a diagram of method  400  for providing converted mass media documents, multimedia documents, or any multimedia content using Multimedia Messaging Service (MMS). A trigger event ( 402 ) causes the retrieval ( 404 ) of documents or content to memory  302 . Trigger event ( 402 ) may be a scheduled PUSH of information at a predetermined time, when a news story is generated, a user request for a multimedia document, a request from device  100  for a multimedia document including as a result of feedback received by one or more sensors  126 , a request from device  200  for a multimedia document including as a result of feedback received by any one of sensors  126 , or an initiation by server or computer  300 . 
         [0041]    Trigger event ( 402 ) may also be a change in the shape or bending of one or more electronic flexible screen or display devices  202  detected by the plurality of sensors  126  that generates a request for documents from server or computer  300 . For this case, documents or content such as html or web content in addition to MMS messages can be delivered to device  318  responsive to the detected change of shape of one or more flexible screen or display devices  202 . This may be done by embedding one or more sensors  126  in one or more flexible screen or display devices  202  or housing members  204  or  206  that detect a change in gradients of the flexible display. 
         [0042]    In one embodiment of the present invention, the retrieval of documents or content ( 404 ) is triggered by initiating a “PRINT to MMS” function, a mouse click function requesting “SEND by MMS”, or a “SEND MULTIMEDIA ONLY by MMS” function on server or computer  300  when configured as a personal computer that can be integrated into a single personal computer application, preferably without the need of any other third party software, and information transported by configuring one or more network adapters  312  as a cellular transceiver or any other wireless or wired communication technology to MMS user agent  316 . A personal computer application may be a web browser where clicking on a link to download a document or a subset of a document also provides the option to download and send the content via a plurality of segments or elements in a plurality of MMS messages. In one embodiment, each multimedia element in the document that is compatible for transport via MMS may have an indicator, such as an icon, so that only compatible multimedia elements are selected for transport. 
         [0043]    Having MMS capabilities on a personal computer enables easy transport and communication of information between a single personal computer application on computer  300  and device  318 . Communication of personal computer content using MMS is advantageous since the number of devices supporting MMS is expected to outgrow the number of devices supporting mobile electronic mail. 
         [0044]    For the “SEND MULTIMEDIA ONLY by MMS” function, photos, audio, and video are sent from the original document or content without the text in the document or content to the intended recipient. This is advantageous if a recipient only desires to see the multimedia content in the original document or content. When the MMS messages having elements  306   1  to  306   3  with only the multimedia content of the original document is received, device  100  or  200  may display the multimedia elements in a list or a cascade based on importance, size, date, quality, type, or any other criteria. If any of the MMS messages represent an advertisement in the original document, the placement of the advertisement on the displays of device  100  or  200  may be based on creating the greatest number of impressions to the user such as on the top, left hand side, or right hand side. Alternatively, received elements  306   1  to  306   3  may be placed in the same position on the displays of device  100  or  200  as they existed in the original document when received. 
         [0045]    Referring again to device  100 , trigger event ( 402 ) may also be GPS device  114  detecting a change in position in the case where device  100  is mobile. Using GPS, elements  306   1  to  306   4  may be transcoded into different audio, image, and video qualities if server or computer  300  determines that device  318  configured as device  100  is in a building, behind heavy foliage, in a tunnel, approaching an unfavorable position in the network, or the like. GPS device  114  can also be used by server or computer  300  to determine when to push a particular advertisement depending on the location of device  318 . This is advantageous for providing localized advertising information. 
         [0046]    For the case that power source  112  receives wireless power from wireless power transmitter  320 , trigger event ( 402 ) may be a change in the proximity to a wireless power coverage area requiring transcoding of subsequent elements  306   1  to  306   4 . If the wireless power coverage area is strong, elements  306   1  to  306   4  may be transcoded into higher quality audio, image, and video since the required increased processing power can be compensated for by the wireless power transmitter  320 . If the wireless power coverage area is weak elements  306   1  to  306   4  may be transcoded into lower quality audio, image, and video in order to conserve power. 
         [0047]    Referring again to device  200 , trigger event ( 402 ) may also be caused on device  200  by one or more sensors  126  detecting motion such as rotation. When device  200  is rotated  214 , content is loaded on the second electronic flexible screen or display device  203  and the one or more electronic flexible screen or display devices  202  is turned off. Another trigger event ( 402 ) in accordance with the present invention is when one or more sensors  126  detect a bending of one or more electronic flexible screen or display devices  202  indicating that the device has been folded or its shape altered, such as made circular, cubicle, or the like. If flexible screen or display devices  202  is folded or bent, the delivered MMS messages received by device  200  will be altered or resized to fit the new shape. For each trigger event ( 402 ), a request is sent to computer  200  for a multimedia document or content subsequent to the trigger event on device  200 . 
         [0048]    Subsequent to retrieval ( 404 ), the document or content is extracted, parsed, and/or segmented into a plurality of elements  306   1  to  306   4  and each converted into individual MMS messages ( 406 ) by converter engine  304 . Each element  306   1  to  306   4  comprises an individual video, image, audio, or text information of the document or content. Optionally, an MMS assembler message may then be generated ( 408 ) in order for the recipient MMS user agent  316  to know how to properly reassemble the received elements. Rather than an independent MMS assembler message, the position and placement information within the original document or content of the information delivered in each MMS message may be embedded in the header or body of the MMS message for proper reassembly. Alternatively, a template of a page or publication may be stored on device  100  and used to properly reassemble all the transmitted and received MMS elements into the original document. 
         [0049]    Elements  306   1  to  306   4  representing the original document or content are then transmitted over network  314  using a plurality of MMS messages with optionally the MMS assembler message ( 410 ) to MMS user agent  316 . The MMS messages are then received optionally with the MMS assembler message ( 412 ). The original document or content is then reassembled optionally using the MMS assembler message or embedded information ( 414 ). 
         [0050]      FIG. 5  is a diagram of communicating converted mass media, multimedia documents, or any multimedia content using a plurality of MMS messages. A multimedia document or content  502  is either extracted, parsed, and/or segmented into image element  502   1 , audio element  502   2 , text element  502   3 , and video element  502   4  and an MMS message is generated for each element. An MMS assembler message  504  may optionally be generated having information to properly reassemble converted document or content  502 . Alternatively, each MMS message having any one of elements  502   1  to  502   4  may have embedded information for reassembling the converted document or content  502 . The embedded information includes placement or positioning information of the image, audio, text, or video element within the original document or content. MMS messages  506   1 - 506   4  and optionally MMS assembler message  504  is communicated over network  507  in any order. MMS messages  502   1 - 502   4  are received as elements  510   1 - 510   4  along with MMS assembler message  508 . The original multimedia document or content  502  is reassembled as each element is received and displayed in segments. 
         [0051]    Although the features and elements of the present invention are described in the preferred embodiments in particular combinations, each feature or element can be used alone without the other features and elements of the preferred embodiments or in various combinations with or without other features and elements of the present invention.
