Abstract

An apparatus and method for providing adapted web page content to a client are described. Here, a variety of pre-generated versions of the same web content are stored in a server in advance of the receipt of client requests therefore. Each version is adapted to be displayed on a device with particular display characteristics. Then, when a client request for the content is received, the client display characteristics are determined, and the appropriate version for the client display characteristics selected from the stored versions. The selected version is then sent to the client. In a preferred embodiment, if there is no matching version to the client display characteristics, then a matching version is dynamically generated on the fly.

Claims

1. An apparatus for providing web page content to a display device, the apparatus comprising:

a content store arranged to store a plurality of different versions of the same web page content, each version being adapted for display on an intended display device having a set of one or more defined display characteristics;

means for receiving requests for web page content from display devices;

display device characteristic determining means arranged to determine the one or more display characteristics of a display device from which a request for web content is received;

content version selection means arranged to select a version of the web content stored in the content store in dependence on the determined display characteristics of the display device from which a request for web content was received, the selected version being that which is adapted for display on display devices having the determined display characteristics; and

means for transmitting the selected version to the display device.

2. An apparatus according to claim 1, and further comprising adaptation means arranged to adapt said web page content in dependence on the determined display characteristics of the display device from which a request for web content is received so as to provide a version of the web page content adapted for display on the such device, said adaptation means being operable in the event that the content version selection means determines there is no version in the content store which is adapted for display on the device having the determined display characteristics.

3. An apparatus according to claim 2 wherein said adaptation means further comprises:

i) web page content analysis means for analysing the web page content to determine one or more characteristics thereof;

said adaptation means being further arranged to adapt the web page content to provide the adapted version in dependence on the output of the web page content analysis means.

4. An apparatus according to claim 3, wherein said web page content analysis means further comprises object detection means for detecting display objects in said web page content;

and object size calculation means for calculating the size of said display objects.

5. An apparatus according to claim 3, wherein said web page content analysis means further comprises object detection means for detecting display objects in said web page content;

and object function detecting means for determining the function of said detected objects.

6. An apparatus according to claim 3 wherein said web page content analysis means further comprises object detection means for detecting display objects in said web page content;

object structure detecting means for determining the structure of said display objects; and

object structure grouping means for grouping those objects which are determined to have the same or substantially the same structure.

7. An apparatus according to claim 3, wherein said web page content analysis means further comprises object detection means for detecting display objects in said web page content;

object pattern detecting means for matching the detected display objects on the basis of their display patterns; and

object pattern grouping means for clustering those display objects which match into groups.

8. An apparatus according to claim 2, wherein said adaptation means further comprises content transforming means arranged in use to apply one or more content transformations to said web page content.

9. An apparatus according to claim 8, and further comprising transformation evaluation means arranged to operate where more than one transformation is applied, and to evaluate each transformation after it is performed to determine whether the transformed content is capable of being displayed on the intended display device;

wherein the transformation evaluating means is further arranged to control the content transforming means to apply the transformations in turn until such evaluation indicates that the transformed content is suitable for such display.

10. A method of providing web page content to a display device, the method comprising:

storing a plurality of different versions of the same web page content, each version being adapted for display on an intended display device having a set of one or more defined display characteristics;

receiving requests for web page content from display devices;

determining the one or more display characteristics of a display device from which a request for web content is received;

selecting a version of the web content stored in the content store in dependence on the determined display characteristics of the display device from which a request for web content was received, the selected version being that which is adapted for display on display devices having the determined display characteristics; and

transmitting the selected version to the display device.

11. A method according to claim 10, and further comprising the step of adapting said web page content in dependence on the determined display characteristics of the display device from which a request for web content is received so as to provide a version of the web page content adapted for display on the such device, said adapting step being operable in the event that the selecting step determines that there is no version in the content store which is adapted for display on the device having the determined display characteristics.

12. A method according to claim 11, wherein said adapting step (c) further comprises the steps of:

i) analysing the web page content to determine one or more characteristics thereof; and

ii) adapting the web page content to provide the adapted version in dependence on the results of the analysis step.

13. A method according to claim 12, wherein said analysing step (i) further comprises detecting display objects in said web page content, and calculating the size of said display objects.

14. A process according to claim 12, wherein said analysing step (i) further comprises detecting display objects in said web page content, and determining the function of said detected objects.

15. A process according to claim 12 wherein said analysing step (i) further comprises detecting display objects in said web page content;

determining the structure of said display objects; and

grouping those objects which are determined to have the same or substantially the same structure.

16. A process according to claim 12, wherein said analysing step (i) further comprises detecting display objects in said web page content;

matching the detected display objects on the basis of their display patterns; and

clustering those display objects which match into groups.

17. A process according to claim 12, wherein said adapting step further comprises applying one or more content transformations to said web page content.

18. A process according to claim 17, wherein where more than one transformation is applied, an evaluation is performed after each transformation to determine whether the transformed content is capable of being displayed on the intended display device, and the transformations are applied in turn until such evaluation indicates that the transformed content is suitable for such display.

19. A computer program or suite of programs so arranged such that when executed by a computer system it/they cause/s the system to perform the process of claim 10.

20. A modulated carrier signal incorporating data corresponding to the computer program or at least one of the suite of programs of claim 19.

21. A computer readable storage medium storing a computer program or at least one of suite of computer programs according to claim 19.
