     BACKGROUND OF THE INVENTION 
     1. Field of Invention 
     This invention relates generally to multimedia devices. More specifically, the invention describes a system for providing multimedia data to a mobile personal communication device. Such devices include but are not limited to cell phones, walkie-talkies, etc. 
     2. Description of Related Art 
     Recent developments in consumer electronics have included the introduction of portable personal communication devices such as cell phones, personal walkie-talkies, and the like. A common use for such personal communication devices is the sending and receiving of text messages. However, conventional text messaging systems require the use of what is referred to as a backend server that may be limited in the amount of information that can be handled at a particular time and is therefore capacity limited. Furthermore, the reading of text messages can be troublesome due to in part to the small size of the typical display screen or the inability to control ambient light conditions. This is particularly troublesome to those users having impaired vision where reading a text message, of any reasonable size, for example, is difficult. 
     What is required is a system that provides for vocalization of multimedia data by a personal communication device for transmission over an associated voice channel. 
     SUMMARY OF THE INVENTION 
     The invention described herein pertains to method of transferring multimedia data between personal communication devices by vocalizing the multimedia data by a first personal communication device, passing the vocalized multimedia data to a second personal communication device using only a voice channel, and receiving the vocalized multimedia data by the second personal communication device. 
     In another embodiment, a consumer product suitable transferring multimedia data between personal communication devices without a backend server is described that includes a memory device arranged to store the multimedia data, a display coupled to the memory device suitable for displaying the multimedia data, a wireless interface arranged to establish a voice channel between the consumer product and any of the personal communication devices and an audio output device for outputting an audible signal. A processor fetches the multimedia data from the memory, vocalizes the multimedia data and passes the vocalized multimedia data to the wireless interface that subsequently passes the vocalized multimedia data by way of the voice channel to at least one of the personal communication devices. 
     Computer program product executable by a processor for transferring multimedia data between personal communication devices without a backend server, is also described. The computer program product includes computer code for vocalizing the multimedia data by a first personal communication device, computer code for passing the vocalized multimedia data to a second personal communication device using only a voice channel, computer code for receiving the vocalized multimedia data by the second personal communication device and computer readable medium for storing the computer code. 
     Other aspects and advantages of the invention will become apparent from the following detailed description, taken in conjunction with the accompanying drawings, illustrating by way of example the principles of the invention.

     DETAILED DESCRIPTION OF SELECTED EMBODIMENTS 
     Reference will now be made in detail to a preferred embodiment of the invention. An example of the preferred embodiment is illustrated in the accompanying drawings. While the invention will be described in conjunction with a preferred embodiment, it will be understood that it is not intended to limit the invention to one preferred embodiment. To the contrary, it is intended to cover alternatives, modifications, and equivalents as may be included within the spirit and scope of the invention as defined by the appended claims. 
     With the rapid deployment, proliferation, and technical advancement of mobile personal communication devices, such as cell phones, a user of these devices is presented with any number of ways to communicate with another user. For example, a user can send type a text message using, for example, Short Message Service-Point to Point (SMS-PP) protocol as defined in GSM recommendation 03.40 where messages are sent via a store-and forward mechanism to a Short Message Service Center (SMSC), which will attempt to send the message to the recipient and possibly retry if the user is not reachable at a given moment. Therefore, SMS-PP requires the use of a backend server to provide the necessary support for transmission of data between sender and receiver. 
     The invention, however, provides a mechanism whereby data is passed between a sender and receiver unit by way of voice channel only bypassing use of the data channel used in conventional arrangements. In this way, a sender can select that data which he/she desires to send to a receiver unit using by first converting the data into an appropriate vocal/voice format which is then forwarded to a receiver unit by way of the voice channel. Once received at the receiver unit, the vocalized data can be converted to an audio signal, which is then output by way of an audio output device (such as a speaker, earphone, etc.). This arrangement is particularly well suited for people having visual problems or in those situations where viewing the data on a small display screen (typical of most personal communication devices) is problematic. 
     In one embodiment, the personal communication device is a pocket sized cell phone that in addition to the standard voice function of a telephone can support many additional services such as SMS for text messaging packet switching for access to the Internet and MMS for sending and receiving photos and video. 
     Accordingly,  FIG. 1  shows an exemplary personal communication device  100  (such as a cell phone) in accordance with an embodiment of the invention. The cell phone  100  includes a processor  102  that pertains to a microprocessor or controller for controlling the overall operation of the cell phone  100  that stores data in a RAM  104  and a Read-Only Memory (ROM)  106 . The ROM  106  can store programs, utilities or processes to be executed in a non-volatile manner whereas the RAM  104  provides volatile data storage such as currently called phone numbers, ring tones, etc. The cell phone  100  also includes a user input device  108  that allows a user to interact with the cell phone  100 . For example, the user input device  108  can take a variety of forms, such as a button, keypad, dial, etc. Still further, the cell phone  100  includes a display  110  (screen display) that can be controlled by the processor  102  to display information to the user. A data bus can facilitate data transfer between at least the ROM  106 , RAM  104 , the processor  102 , and a CODEC  112  that produces analog output signals for an audio output device  114  (such as a speaker). The speaker  114  can be a speaker internal to the cell phone  100  or external to the cell phone  100 . For example, headphones or earphones that connect to the cell phone  100  would be considered an external speaker. A wireless interface  116  operates to receive information from the processor  102  that opens a channel (either voice or data) for transmission and reception typically using RF carrier waves. 
       FIG. 2  shows a system  200  having a cell phone  202  arranged to pass vocalized multimedia data to a receiver unit  204  in accordance with an embodiment of the invention. It should be noted that the system  200  can be used by any number of cell phones or other compatible personal communication devices and is not therefore limited to only the particular embodiment shown in  FIG. 2 . Accordingly, when the cell phone  202  is actively displaying multimedia data  206  on a display screen  208 , a user has the option of having the cell phone  202  vocalize the displayed data (which in this example is a phone number “650 555-1234”) in order to be passed by way of a voice channel  210  to the receiver unit  204  (in this case another cell phone) or any number of other cell phones or compatible personal communication devices. 
     Once received at the cell phone  204 , processing of the vocalized data can be performed based upon a prompted user request or based upon a pre-selected protocol. For example, once received at the cell phone  204 , the vocalized phone number can be passed to an audio output device  212  that (in the case of a speaker) generates an audible rendition of the vocalized phone number. In another case (shown in  FIG. 3 ), the vocalized phone number is forwarded to a voice mail server  300  where the receiver records the vocalized phone number as a voice mail message for subsequent playback. It should be noted that in this case, the sender can pre-select this option for those cases where the sender wishes to generate a simple text message and instead of having the text message displayed on the receiver&#39;s display screen, the vocalized text message is stored in the receiver&#39;s voice mail server. 
       FIG. 4  shows a flowchart illustrating a particular process  400  for transferring multimedia data over a voice channel in accordance with an embodiment of the invention. Accordingly, at  402 , voice channel is opened or otherwise made available for transmission of the multimedia data. At  404 , multimedia data is displayed on a display screen. In the described embodiment, various user selectable icons are available for selecting some or all of the displayed multimedia data. For example, if the displayed multimedia data is textual in nature (such as a phone number or short test message), a pointer can be used to point to and select the portion of the text to send. Therefore, at  406  a user selection of the displayed multimedia data (or portion thereof) is received along with a user prompt at  408  that causes the cell phone to vocalize the selected multimedia data in preparation for transmission over the available voice channel. At  410 , the selected multimedia data is vocalized and transmitted over the voice channel at  412  to a receiver unit. 
       FIG. 5  shows a flowchart detailing a process  500  for receiving vocalized multimedia data in accordance with an embodiment of the invention. The process  500  begins at  502  by receiving the vocalized multimedia data over the voice channel. If, at  504 , it is determined that there is no further processing, then the process  500  stops, otherwise, the vocalized multimedia data is further processed at  506 . By further processing, it is meant that once the vocalized multimedia data is received, there are any number of additional processing that can be performed, such as passing the vocalized multimedia data to an output audio device (such as a speaker, headphone jack, etc.) for conversion to an audible version of the vocalized multimedia data. In some cases, default additional processing can be performed whereby any vocalized multimedia data received is automatically converted back to text and displayed and/or converted to an audible message. 
     For example,  FIG. 6  shows a flowchart detailing a process  600  for forwarding the vocalized multimedia data to a voicemail server in accordance with an embodiment of the invention. The process  600  begins at  602  by (optionally) displaying the vocalized multimedia data and forwarding the vocalized multimedia data to a voice mail server at  604  and updating a voice mail indicator at  606  indicating that a new voice mail message has been recorded. 
     While this invention has been described in terms of a preferred embodiment, there are alterations, permutations, and equivalents that fall within the scope of this invention. It should also be noted that there are many alternative ways of implementing both the process and apparatus of the present invention. It is therefore intended that the invention be interpreted as including all such alterations, permutations, and equivalents as fall within the true spirit and scope of the present invention.
