Abstract

A media spooler system is described that provides a methodology for efficient transmission of media content from client devices, such transmission of digital images from wireless digital cameras. The media spooler or gateway addresses wireless transmission problems by acting as a protocol gateway between a thin-client device and a target host or server (supported by a server infrastructure). More particularly, the media spooler of the present invention acts as a protocol gateway between thin-client devices (e.g., “mobile visual communicator” in the form of a wireless digital camera) and server infrastructure (e.g., server-based computer systems or “Web servers” of a photographic service provider). This task entails accepting multiple, simultaneous connections from various client devices (e.g., wireless digital cameras), extracting information from those devices (e.g., digital photographs or other media content), and then uploading that information to the target server infrastructure. In basic operation, the media spooler queries each client device for the information (e.g., media, such as pictures) the client device thinks should uploaded, and then the media spooler queries the server infrastructure for the subset of pictures that have not been already uploaded. This improved coordination or synchronization of information between a device and target host allows for efficient recovery of dropped cellular data calls by essentially allowing the media spooler to “pick up where it left off.”

Claims

1. In a wireless environment, a method for efficiently transmitting digital images from a wireless device, the method comprising:

transmitting information pertaining to a digital image to be uploaded from the wireless device to the wireless carrier;

collecting, at a spooler, the information being transmitted for said digital image;

initiating transmission of the digital image; and

detecting an interruption of the transmission, and upon re-establishing another connection, resuming transmission of the digital image without retransmitting the entire digital image.

2. The method of claim 1, further comprising establishing a data call from the wireless device to a wireless carrier for uploading digital images, wherein establishing the data call includes:

connecting a digital camera with wireless connectivity to a cellular phone device; and

placing a data call through the cellular phone device.

3. The method of claim 1, wherein the wireless device resumes transmission of said digital image at a point of the last successfully-received byte of data.

4. The method of claim 1, further comprising:

determining which digital images are required to be uploaded, based, at least in part, on digital images already successfully uploaded.

5. The method of claim 1, further comprising:

receiving concurrent data calls from a plurality of client devices, such that a multitude of connections exist with a multitude of digital images being simultaneously transmitted.

6. The method of claim 1, further comprising:

logging information characterizing each transmission, thereby providing information supporting per-image or time-based billing.

7. The method of claim 6, wherein logging information includes:

logging information describing how many images have been transmitted from the wireless device.

8. The method of claim 1, wherein each digital image is identified by a globally-unique identifier.

9. The method of claim 8, wherein the globally-unique identifier of each digital image is based, at least in part, on a device ID of the wireless device where the image originated.

10. A system for efficiently transmitting digital images from a wireless device comprising:

a wireless device capable of establishing a connection to a server for uploading digital images;

a module directing transmission of information pertaining to a digital image to be uploaded from the wireless device to the server; and

a system to initiate transmission of the digital image; and

the system further to detect an interruption of the transmission, and upon re-establishing another connection, resume transmission of the digital image without retransmitting the entire digital image.

11. The system of claim 10, wherein transmission of said digital image resumes at a point of the last successfully-received byte of data.

12. The system of claim 10, further comprising:

a logger module for logging information characterizing each connection, thereby providing information supporting per-image or time-based billing.

13. The system of claim 12, wherein said logger module logs information describing how many images have been transmitted from the wireless device.

14. The system of claim 12, wherein said logger module logs information describing the duration of the data call.

15. The system of claim 10, wherein each digital image is identified by a globally-unique identifier.

16. The system of claim 15, wherein the globally-unique identifier of each digital image is based, at least in part, on a device ID of the wireless device where the image originated.

17. In a wireless environment, a method for efficiently transmitting media content from a wireless device, the method comprising:

establishing a connection from the wireless device to a wireless carrier for uploading selected media content;

transmitting information pertaining to the selected media content to be uploaded from the wireless device to the wireless carrier;

collecting, at a spooler, the information being transmitted for said selected media content;

once the spooler has collected sufficient information, transmitting data the spooler to a target computer;

detecting the drop of the connection; and

upon establishing another connection, resuming transmission of said selected media content without retransmitting portions of said selected media content that have already been transmitted.

18. The method of claim 17, further comprising:

receiving concurrent data calls from a plurality of client devices, such that a multitude of connections exist with a multitude of different media content being simultaneously transmitted.

19. The method of claim 17, further comprising:

determining at the spooler which portions of said selected media content are required to be uploaded, based, at least in part, by querying the target computer for a list of all portions, if any, already successfully uploaded.

20. The method of claim 17, further comprising:

logging information characterizing each connection, thereby providing information supporting per-image or time-based billing.

21. The method of claim 20, wherein the logging information describes how many images have been transmitted from the wireless device.

22. The method of claim 17, wherein each digital image is identified by a globally-unique identifier.

23. The method of claim 22, wherein the globally-unique identifier of each digital image is based, at least in part, on a device ID of the wireless device where the image originated.
