Abstract

A system and method for remotely displaying a plurality of data items is disclosed. The system determines a total quantity of displayable data items and optionally receives an indication of a display control size from a remote client. The server stores a threshold value indicating a relationship between a quantity of data items and a size of a display control. The server compares the quantity of data items and the received indication of the display control size. If the comparison exceeds the threshold value, the server sends a subset of the items to the remote client for display, and sends additional items as requested by the remote client. If the comparison is less than the threshold value, the server sends each of the items to the remote client for display. The server repeats this comparison for changes in the quantity of data items or the size of the display control.

storing a threshold value;

if the relationship value exceeds the threshold value, sending the data representing the plurality of items to the remote location for display; and

if the relationship value does not exceed the threshold value, sending a subset of the data representing the plurality of items to the remote location for display.

2. The method of claim 1, wherein the relationship value is a first relationship value, and which includes receiving data indicating a desired change in the quantity associated with the plurality of items and determining a second relationship value indicative of the relationship between the display control dimension and the changed quantity.

3. The method of claim 2, wherein the data indicating a desired change in the quantity associated with the plurality of items includes data indicating an addition or a deletion of at least one item.

4. The method of claim 1, wherein the threshold value is based, at least in part, on a set of hardware specifications of a machine at the remote location.

5. The method of claim 4, wherein the set of hardware specifications includes at least one selected from the group consisting of:

a processor speed of the machine, a monitor size of the machine, and an amount of memory of the machine.

6. The method of claim 1, wherein the threshold value is based, at least in part, on a network connection speed of a network.

7. The method of claim 1, wherein determining the relationship value includes calculating a ratio between the display control dimension and the quantity associated with the plurality of items.

8. The method of claim 1, wherein the display control dimension reflects a quantity of items simultaneously displayable by the display control.

9. The method of claim 1, wherein the display control dimension reflects a quantity of pixels of a height of the display control.

10. The method of claim 1, wherein the quantity associated with the plurality of items indicates a number of the plurality of items.

11. The method of claim 1, wherein the quantity associated with the plurality of items indicates a storage size of the plurality of items in bytes.

12. The method of claim 1, wherein the subset of the data is a first subset, and which includes, if the relationship value does not exceed the threshold, sending a second, different subset of the data upon receiving data indicating a scroll input.

13. The method of claim 1, wherein at least one of the items is associated with content data, and which includes, if the relationship value exceeds the threshold value, sending the data representative of the plurality of items and the associated content data to the remote location.

14. The method of claim 1, wherein at least one of the items is associated with content data, and which includes, if the relationship value does not exceed the threshold value, sending the subset of the data representing the plurality of items and the content data associated with the items represented by the subset of the data to the remote location.

15. The method of claim 1, which includes receiving the display control dimension from the remote location.

16. The method of claim 1, wherein the request for data representing the plurality of items includes information about a display control, the information about the display control including information representative of the display control dimension.

17. The method of sending data for display at a destination, the method comprising:

receiving from the destination a request for the data;

determining a quantity indicative of the size of the data;

determining a comparison ratio between the quantity indicative of the size of the data and a display control size;

if the comparison ratio is in a first quantifiable relationship with a threshold ratio, sending a subset of the data to the destination for display; and

if the comparison ratio is in a second quantifiable relationship with the threshold ratio, sending the data to the destination for display.

18. The method of claim 17, wherein the destination is a remote client device configured to display at least a subset of the data.

19. The method of claim 17, wherein the destination is a process executed by a local processor.

20. The method of claim 17, wherein the destination is local Random Access Memory (RAM).

21. The method of claim 17, wherein the first quantifiable relationship includes the comparison ratio exceeding the threshold ratio, and wherein the second quantifiable relationship includes the comparison ratio not exceeding the threshold ratio.

22. The method of claim 17, wherein the first quantifiable relationship includes the comparison ratio not exceeding the threshold ratio, and wherein the second quantifiable relationship includes the comparison ratio exceeding the threshold ratio.

23. The method of claim 17, wherein the display control size reflects a quantity of items simultaneously displayable by the display control.

24. The method of claim 17, wherein the display control size reflects a quantity of pixels of a height of the display control.

25. The method of claim 17, wherein the quantity indicative of the size of the data represents a number of data items of the data.

26. The method of claim 17, wherein the quantity indicative of the size of the data represents a storage size of the data in bytes.
