Abstract

A system and method is disclosed for enhanced data transfer methods within control environment for implementing functions on control devices. Generally, as a user browses content on a Content Server via a Control Point, various content sets will be concatenated by the Content Server based on an initial request from the Control Point, and all content in the content set will be sent as a single item from the Content Server to the Control Point, thus minimizing the number of message round trips and thus the protocol overhead needed to retrieve all content requested by the user. Information about the concatenated content set may be sent separately from the Content Server to the Control Point, or may be embedded in the content set as metadata, such that individual elements of the content set may be selectively displayed, controlled, and/or manipulated by the user via the Control Point.

Claims

1. A server implemented method for transferring a plurality of data elements to a client device, comprising:

receiving a message from the client that specifies a parameter and the plurality of data elements to be transferred;

formatting each of the plurality of data elements in accordance with the parameter;

concatenating the formatted plurality of data elements into a single data element; and

transferring the single data element containing the formatted plurality of data elements to the client.

2. The method as recited in claim 1, wherein the single data element has the same data type as the plurality of data elements.

3. The method as recited in claim 1, wherein formatting each of the plurality of data elements in accordance with the parameter comprises scaling each of the plurality of data elements.

4. The method as recited in claim 1, wherein formatting each of the plurality of data elements in accordance with the parameter comprises compressing each of the plurality of data elements.

5. The method as recited in claim 1, wherein the plurality of data elements comprises data representative of an image.

6. The method as recited in claim 5, wherein formatting each of the plurality of data elements comprises manipulating the image represented by the data of each of the plurality of data elements.

7. A system for transferring data, comprising:

a content server in communication with a client device;

the content server receiving from the client device a message that specifies a parameter and a plurality of data elements to be transferred from the content server to the client device and, in response, functioning to format each of the plurality of data elements in accordance with the parameter, concatenate the formatted plurality of data elements into a single data element, and transfer the single data element containing the formatted plurality of data elements to the client device via a communication link; and

the client device receiving the single data element via the communication link and using the single data element to present a representation of each of the plurality of data elements.

8. The system as recited in claim 7, wherein the client device accepts input which functions to specify at least one of representations of the plurality of data elements to cause the client device to issue a request to retrieve from the content server one or more of the plurality of data elements corresponding to the representations of the plurality of data elements so specified.

9. The system as recited in claim 8, wherein the client device comprises a touch screen device having a plurality of actuation areas used to accept the input which functions to specify at least one of representations of the plurality of data elements.

10. The system as recited in claim 9, wherein the single data file comprises data indicative of an image displayed in the touch screen.

11. The system as recited in claim 10, wherein the client device functions to dice the image and then display one or more of the representations of the plurality of data elements included within the image under a respective on of the plurality of actuation areas.

12. The system as recited in claim 7, wherein the single data element has the same data type as the plurality of data elements.

13. The system as recited in claim 7, wherein each of the plurality of data elements is formatted in accordance with the parameter by scaling each of the plurality of data elements.

14. The system as recited in claim 7, wherein each of the plurality of data elements is formatted in accordance with the parameter by compressing each of the plurality of data elements.

15. The system as recited in claim 7, wherein the plurality of data elements comprises data representative of an image.

16. The system as recited in claim 15, wherein each of the plurality of data elements is formatted by manipulating the image represented by the data of each of the plurality of data elements.

17. The system as recited in claim 7, wherein the request is formatted as a URL sent to the content server by the client device.
