Abstract

A method for providing a low fidelity alternative until a high fidelity experience becomes available is provided. Upon detecting a need to download data, a download manager determines a download priority for downloading the data. The download priority specifies an amount of a low fidelity representation of data to download prior to downloading a high fidelity representation of the same data and any remaining low fidelity representation of the data simultaneously. The download manager then downloads, for example, from a content server, the low fidelity representation of the data and the high fidelity representation of the data according to the determined download priority, thus allowing the low fidelity representation of the data to be used until the high fidelity representation of the data is downloaded and becomes available.

Claims

1. A method in a client application of a client computing device for providing a low fidelity representation of data until a high fidelity representation of the same data becomes available, the method comprising:

establishing a communication channel between the client computing device and a content server providing datasets for download by the client computing device, wherein a dataset represents data and comprises at least a low fidelity representation of the data and a high fidelity representation of the data, the low fidelity representation of the data being divided into portions such that when a portion is received the portion can be used without having to wait until the other portions of the low fidelity representation of the data is received, the high fidelity representation of the data not being divided into portions such that the high fidelity representation of the data cannot be used until all the high fidelity representation of the data is received; and

upon detecting a need to download data from the content server,

determining by the client computing device a download priority for downloading the low fidelity representation of the data and the high fidelity representation of the same data wherein the low fidelity representation of a portion of the data is given a higher priority than the high fidelity representation of the entire data and the low fidelity representation of another portion of the data is given a lower priority than that high fidelity representation of that data;

requesting the content server to download to the client computing device the low fidelity representation of the data and the high fidelity representation of the data in the determined download priority; and

receiving at the client computing device the low fidelity representation of the data and the high fidelity representation of the data, wherein the client application uses the low fidelity representation of the data until the high fidelity representation of the data is downloaded and wherein the portion of the low fidelity representation of the data with the lower priority and the high fidelity representation of the data are downloaded simultaneously such that when the low fidelity representation of the data with the lower priority is downloaded before the high fidelity representation of the data with the higher priority, the low fidelity representation of the data with the lower priority is used before the high fidelity representation of the data with the higher priority.

2. The method of claim 1, wherein the high fidelity representation of the data is downloaded only if the communication channel exceeds a predetermined bandwidth.

3. The method of claim 1, wherein the low fidelity representation of the data is downloaded only if the difference in size between an item of low fidelity content representing the data and the high fidelity representation of the data exceeds a predetermined value.

4. The method of claim 1 further comprising, prior to downloading the low fidelity representation of the data, determining if there is local copy of the low fidelity representation of the data and downloading the low fidelity representation of the data if a local copy of the low fidelity representation of the data does not exist.

5. The method of claim 1, wherein the download priority is determined at least in part from a use factor.

6. The method of claim 1, wherein the download priority specifies an amount of the low fidelity representation of the data to download prior to starting the download of the high fidelity representation of the data.

7. The method of claim 1, wherein the high fidelity representation of the data is non-streamable.

8. The method of claim 1 further comprising, upon downloading of the high fidelity representation of the data, canceling the downloading of the low fidelity representation of the data.

9. The method of claim 1, wherein the dataset further comprises a third fidelity representation of the data.

10. A client computing system for providing a low fidelity representation of data until a high fidelity representation of the same data becomes available, the system comprising:

a memory storing

a communications component with computer-executable instructions that establishes a communication channel to a content server that provides datasets for download by the computing system, wherein a dataset represents data and comprises at least a low fidelity representation of the data and a high fidelity representation of the data, the low fidelity representation of the data being divided into portions such that when a portion is received the portion can be used without having to wait until the other portions of the low fidelity representation of the data is received, the high fidelity representation of the data not being divided into portions such that the high fidelity representation of the data cannot be used until all the high fidelity representation of the data is received; and

a download manager component with computer-executable instructions that detects a need to download data from the content server, and upon detecting the need to download data,

determines a download priority that specifies an amount of the low fidelity representation of the data to download prior to downloading the high fidelity representation of the same data and any remaining low fidelity representation of the data, wherein the specified amount of low fidelity representation of the data is given a higher priority than the high fidelity representation of the data and the remaining low fidelity representation of the data is given a lower priority than that high fidelity representation of that data; and

downloads the low fidelity representation of the data and the high fidelity representation of the data according to the download priority wherein the client computing system uses the low fidelity representation of the data until the high fidelity representation of the data is downloaded and wherein the remaining low fidelity representation of the data with the lower priority and the high fidelity representation of the data are downloaded simultaneously such that when the remaining low fidelity representation of the data with the lower priority is downloaded before the high fidelity representation of the data with the higher priority, the remaining low fidelity representation of the data with the lower priority is used before the high fidelity representation of the data with the higher priority; and

a processor that executes the computer-executable instructions of the components.

11. The client computing system of claim 10, wherein the download manager component further terminates the downloading of the remaining low fidelity representation of the data upon completing the download of the high fidelity representation of the data.

12. The client computing system of claim 10, wherein the download manager uses a download priority queue to establish the download priority.

13. The client computing system of claim 10, wherein the download manager maintains a local copy of the low fidelity representation of the data.

14. The client computing system of claim 10, wherein the download priority is determined in part by applying a weight to the low fidelity representation of the data and the high fidelity representation of the data based on the use of the data.

15. The client computing system of claim 10, wherein the high fidelity data is non-streamable.
