In some embodiments, metadata refers to data associated with a file that describes attributes and other information about the file. The metadata may refer to special tagged fields in a document that provide information about the document to search engines and other computer applications, such as layout information and placeholders for objects (e.g., text, graphics, formatting structures, etc.). Metadata may include information regarding the source, author, time of creation, time last saved, and other information related to and/or descriptive of the file and the data content thereof. In some embodiments, metadata may include a subset of the actual data content of an associated file. The subset of data may be a relatively small portion of the data content of the file, for example, a first few words of paragraph, a first and/or last line of a paragraph and/or page, or other limited data of the file.
In some embodiments, the metadata associated with a file requires fewer resources to store and transmit than the full content of data of the file. That is, for example, metadata associated with and descriptive of a document file including text and graphics may be, in general, smaller than the document file. Accordingly, fewer resources may be used to store, transmit, and otherwise process metadata associated with a file relative to the storing, transmitting, and other processing of the file itself. The metadata associated with a file may be smaller than the associated file since, for example, the metadata is a description of the file, not the entirety of the data content of the file.

For example, and not as a limitation, external device 210 may include a mobile telephone, a desktop computer, a laptop computer, a handheld computer, a PDA, a digital media player, a digital camera, a wireless email device, and any other device, devices, or system from which a file, stored or at least accessible, may be transmitted.
It should be understood that the block diagram representations of wireless communication device 205 and external device 210 shown in
The methods of operation disclosed herein are, in general, not limited by any title or descriptor associated therewith, but in general are associated with the operations, steps, process, functions, etc. used, disclosed, and suggested in the description of the methods. It should be appreciated that the order of the depicted operations of the flow diagrams are not intended to limit the methods herein to a particular order or sequence of operations.
Transmission(s) of files and information associated with a file, such as metadata and/or at least a portion of the file may be performed using any wired or wireless transmission system that is or becomes known, including various combinations of wired and wireless communication links having a variety of protocols, frequencies, power, etc.
At an initial operation 405, an external device is queried for a file. The query may be presented in any format suitable to the external device. The query may be transmitted via any transmission media and protocols compatible with the external device. In some embodiments, the query to the external device (e.g., 210) may be transmitted in response to a user input received by the wireless communication device (e.g., 205). The user input may include, for example, a request for the file. In some embodiments the query may be transmitted in response to a process to transfer a file to wireless communication device 205 by another device, system, or service. That is, in some embodiments instead of directly receiving a transmission or transfer of a file, wireless communication device may invoke a process such as process 400 to control a receipt of the file by wireless communication device 205.
The query of the external device for the requested file may be communicated to the external device via a wireless communication link between the wireless communication device 205 and the external device 210. The communication link may include any of a number of known and future developed communication systems and protocols.
At operation 410, wireless communication device 205 receives metadata associated with the file from external device 210. In some embodiments, the file queried for is stored in memory associated with the external device. For example, the file may be stored in a memory device connected (fixed, internal, or removable) to external device 210. As mentioned above, the metadata is descriptive of various aspects of the file, and does not contain the entirety of the content of the file. Accordingly, the metadata associated with the file, in general, is smaller than the entire content of the file. Thus, the resources (e.g., memory, transmission bandwidth, and processing power) needed to store, transmit, and process the metadata may be reduced relative to the memory, transmission bandwidth, and processing power needed to store, transmit, and process the file data itself.
At operation 415, wireless communication device 205 generates a preview image of the file based on the metadata and a capability of the wireless communication device. In some embodiments, a preview image includes a lower resolution rendering of the file, a graphic representation of data associated with the file, a limited portion of data associated with the file, and combinations thereof. The graphic representations may include place-holders, icons, shaded areas, hyperlinks, or other objects representative of the content (e.g., text and graphics) of the file.
Wireless communication device 205 may receive the metadata from a external device 210 according to any protocol and via any medium (wireless and wire) compatible with wireless communication device.
Document server 210 includes a number of drivers, supporting the types of documents processed thereby, to parse different types of corresponding documents. For example, document server 210 includes a text editor driver 520 to parse text files, a spreadsheet application driver 525 to parse a file containing spreadsheets, and a presentation application driver 530 to parse files containing presentations. The appropriate driver(s) parse a file and forwards the data to a DPM generator 515. DPM generator 515 generates metadata associated with a file that is transmitted to mobile phone 205 in response to a query for the file. It should be appreciated that any number of application drivers and the like may be included in document server 210 to accommodate a variety of different file types.
In some embodiments herein, wireless communication device 205 is capable of handling (i.e., receiving and processing) metadata associated with a variety of different file types in an instance the metadata associated with the files is formatted to be compatible with wireless communication device 205. The wireless communication device may thus operate independent of a particular format of a file. Any file dependent processing may be handled by the external device 210 (e.g., document server), including the application drivers therein.
It should be appreciated that external device 210 may handle certain functions and/or processing of a file. Such functions include printing a documents and transmitting a message (e.g., SMS, MMS, etc.) including or reporting a status of the file. Further, processing by the external device may not involve over-the-air transmission or using transmission bandwidth to provide the processing functionality.
In some embodiments, the display of the preview image will generally contain less information associated with the file than a display of the information associated with the file. For example,
Returning to
In some embodiments, the displaying of a preview image prior to the retrieval of the entirety of the content of data, or at least that portion of data content used to provide a full resolution rendering of the file, may facilitate efficient viewing of a file that is transmitted from an external device and displayed by a wireless communication device.
At operation 710, a portion of the preview image is selected or otherwise indicated for viewing and/or editing. In response to a user input or actions of selecting at least a portion of the preview image, at least a portion of additional data content associated with the file is retrieved. In some embodiments, the data content associated with the selected or otherwise indicated portion of the preview image is retrieved.
At operation 715, additional data associated with the queried for file is received from the external device. The additional information associated with the file may include at least a portion of the content of the file. In some embodiments, retrieval of the additional data may occur during a display of a preview image that is based on the metadata and a capability of the wireless communication device.
While various embodiments of the present disclosure have been discussed in the context of a wireless communication system, the wireless communication devices and external devices discussed herein may communicate via a wired or wireless communication link. Benefits, such as the off-loading of various processing functions to the external device, may be realized in a system wherein the communication link is wired, at least partially.
Embodiments described above are not intended to be limited to the specific form set forth herein, but are intended to cover such alternatives, modifications and equivalents as can reasonably be included within the spirit and scope of the appended claims.
