Abstract

This invention relates to efficiently transmitting images or other multimedia data with the appropriate properties over a network. The original source image data or other multimedia data that resides on a networked server may not have the appropriate characteristics for optimal transmission. The present invention describes a method for converting original source image data or other multimedia data into appropriately characterized data “on the fly”. The administrator of the networked system containing the images or other multimedia data desired for transmission can apply rules as to what properties the image or other multimedia data must possess for efficient transmission. The present invention analyzes the conditions accompanying the image or other multimedia data request, determines the properties the image data or other multimedia data should contain, checks to see if an image or other multimedia data possessing those properties has already been rendered and stored in the memory cache and, if not, then sends the original source image or the original source multimedia data to a conversion engine wherein the source image or other multimedia data is converted to an image or other multimedia data that possess the correct properties to be effectively transmitted. The invention makes available to the network administrator a predetermined set of default rules that can handle many of the conditions typically encountered in an image or other type of multimedia data request, however the network administrator can later modify these rules.

Claims

1. A method for transmitting multimedia content in a networked environment comprising the steps of:

a) receiving a request for multimedia content; and

b) determining an appropriate set of multimedia properties for transmission of said requested multimedia content; and

c) transmitting said requested multimedia content with said multimedia content incorporating said appropriate set of multimedia properties.

2. The method of claim 1 wherein the appropriate set of properties is determined by one or more conditions associated with the request for the multimedia content.

3. The method of claim 2 wherein the one or more conditions associated with the request for the multimedia content includes the type of user device requesting the multimedia content.

4. The method of claim 2 wherein the one or more conditions associated with the request for the multimedia content is a substantive determination of the device'"'"'s and the device'"'"'s associated network'"'"'s data transmission speed

5. The method of claim 2 wherein the one or more conditions associated with the request for the multimedia content includes the network load at the time the multimedia content is requested.

6. The method of claim 2 further comprising the steps of predetermining a rule set against which is compared the one or more conditions associated with the request for the multimedia content.

7. The method of claim 2 further comprising the steps of predetermining a cache of multimedia content with the appropriate sets of properties already applied and making that cache of multimedia content available for transmission.

8. The method of claim 7 wherein, if no multimedia content with the appropriate set of properties is available in the cache, then retrieving non-conditioned multimedia content, applying the appropriate set of properties to that non-conditioned multimedia content, and subsequently transmitting that multimedia content now incorporating the appropriate set of properties.

9. In a networked environment a system for transmitting multimedia content with the appropriate properties, with said properties determined by the conditions prevailing at the time the multimedia content is requested, comprising:

a) a server receiving the request; and

b) said server using a predetermined rule set for determining what multimedia content properties are appropriate for transmission; and

c) an multimedia content rendering engine capable of taking non-conditioned multimedia content and rendering the non-conditioned multimedia content into conditioned multimedia content with the appropriate properties; and

d) said server then delivering said conditioned multimedia content.

10. The system of claim 9 further including a cache of predetermined multimedia content already incorporating the appropriate properties for transmission, whereby the server, upon determining that appropriate multimedia content is already available in said cache, retrieves said appropriate multimedia content for transmission.

11. The system of claim 9 wherein the rule set for determining what multimedia content properties are appropriate for transmission uses as one of the factors the type of client device requesting the multimedia content.

12. The system of claim 9 wherein the rule set for determining what multimedia content properties are appropriate for transmission uses as one of the factors for that determination the requesting device'"'"'s and the requesting device'"'"'s associated network'"'"'s data transmission speed.

13. The system of claim 9 wherein the rule set for determining what multimedia content properties are appropriate for transmission uses as one of the factors for that determination the current network load at the time the multimedia content is requested.

14. In a networked environment a system for transmitting multimedia content with the appropriate properties, with said properties determined by the conditions prevailing at the time the multimedia content is requested, comprising:

a) means for receiving the request; and

b) means for using a predetermined rule set for determining what multimedia content properties are appropriate for transmission; and

c) means for taking a non-conditioned multimedia content and rendering the non-conditioned multimedia content into a conditioned multimedia content with the appropriate properties; and

d) means for transmitting said conditioned multimedia content to the requesting device.

15. The system of claim 14 further including means for caching predetermined multimedia content already incorporating the appropriate properties for transmission, whereby the server, upon determining that the appropriate multimedia content is already available in said cache, retrieves said appropriate multimedia content for transmission.

16. The system of claim 14 wherein the means for generating the rule set for determining what multimedia content properties are appropriate for transmission uses as one of the factors the type of client device requesting the multimedia content.

17. The system of claim 14 wherein the means for generating a rule set for determining what multimedia content properties are appropriate for transmission uses as one of the substantive factors for that determination the client device'"'"'s and the client device'"'"'s associated network'"'"'s data transmission speed.

18. The system of claim 14 wherein the means for generating a rule set for determining what multimedia content properties are appropriate for transmission uses as one of the factors for that determination the current network load at the time the multimedia content is requested.

19. A method for transmitting images in a networked environment comprising the steps of:

a. receiving a request for the image; and

b. determining an appropriate set of image properties for transmission of said requested image wherein said appropriate set of image properties comprise a selection from;

the type of device requesting the image, the network load at the time the image is requested, the content of a cookie read from the requesting device and the bandwidth available to deliver the image to the requesting device; and

c. determining if an image with the appropriate set of properties is available in a cache of images; and

d. if no such image with the appropriate set of properties is available, then sending an original image to an image rendering engine to produce an image with said appropriate set of properties; and

e. delivering said image with the appropriate set of properties to the requesting device.

20. A method for transmitting images in a networked environment comprising the steps of:

a. receiving a request for the image; and

b. determining an appropriate set of image properties for transmission of said requested image with said determination overridden by the image property parameters embedded in the requested image URL'"'"'s query string; and

c. determining if an image with the appropriate set of properties is available in a cache of images; and

d. if no such image with the appropriate set of properties is available, then sending an original image to an image rendering engine to produce an image with said appropriate set of properties; and

 

delivering said image with the appropriate set of properties to the requesting device.
