Abstract

An improved method and apparatus for providing multimedia communication between and client device and a server. The improved method and apparatus allows for communication of information, such as audio or video information from an application program to be communicated through a standard application program interface to a device driver which, in turn communicates the information over a network to a server.

Claims

1. A method of communicating information between a client and a server comprising:

a) an application communicating a data segment representing a real time data stream to a local device application program interface (API);

b) said API communicating said data segment to a device driver;

c) said device driver communicating said data segment over a network

d) said client computing an estimate of an amount of said data segment consumed by said server.

2. The method as recited by claim 1 wherein the application is executing on a client device.

3. The method as recited by claim 1 wherein said real-time data stream represents audio data.

4. The method as recited by claim 1 wherein said real-time data stream represents video data.

5. The method as recited by claim 1 wherein said data segment is communicated over said network through a network API.

6. The method as recited by claim 1 wherein said data segment is communicated to a server over said network.

7. The method as recited by claim 1 wherein said computation is based on time and a data consumption rate.

8. A method of communicating information between a client and a server comprising:

a) an application executing on a client communicating a data segment representing a real time data stream to a local device application program interface (API);

b) said API communicating said data segment to a device driver;

c) said device driver communicating said data segment over a network through a network API to server; and

d) said client computing an estimate of the amount of said data segment consumed by said server.

9. The method as recited by claim 8 wherein said computation is based on time and a data consumption rate.

10. A method of communicating information between a client and a server comprising:

a) the client communicating a first segment of data to the server over a network communication link; and

b) the client computing the amount of the data segment consumed by the server.

11. The method as recited by claim 10 wherein said computation is an estimate based on time and a data consumption rate.

12. The method as recited by claim 10 where said client is executing an application program and said application program communicates said data segment to a real time application program interface.

13. The method as recited by claim 10 further comprising displaying a graphical user interface allowing display of the computed amount of data consumed by the server.

14. A client coupled with a network, the client comprising:

an application program executing on said client and generating real time data;

a local device application program interface (API) executing on said client and communicating real time data with said application program; and

a device driver executing on said client and communciating with said application program interface and said network, wherein said client computes an estimate of an amount of said real time data consumed by a server.

15. The client as recited by claim 14 wherein said real time data is video data.

16. The client as recited by claim 14 wherein said real time data is audio data.
