Abstract

A method for a client to receive streaming media over a network includes receiving data having the streaming media encoded therein and storing the received data in a de-jitter buffer thereby increasing a fullness of the de-jitter buffer. The method further includes, when the fullness reaches a fill level, initiating play out of the stored data from the de-jitter buffer, and changing the fill level while playing out the stored data.

Claims

1. A client for receiving streaming media over a network, the client comprising:

a receiving de-jitter buffer for receiving and playing out the streaming media,

wherein the receiving de-jitter buffer has a changing fill level that changes while playing out the streaming media.

2. The client of claim 1, wherein the fill level is increased gradually.

3. A client for receiving streaming media over a network, the client comprising:

means for receiving data having the streaming media encoded therein;

means for storing the received data in a de-jitter buffer thereby increasing a fullness of the buffer;

means for initiating play out of the stored data from the de-jitter buffer when the fullness reaches a fill level; and

means for changing the fill level while playing out the stored data.

4. A method for a client to receive streaming media over a network, comprising:

receiving data having the streaming media encoded therein;

storing the received data in a de-jitter buffer thereby increasing a fullness of the buffer;

when the fullness reaches a fill level, initiating play out of the stored data from the de-jitter buffer; and

changing the fill level while playing out the stored data.

5. The method of claim 4, wherein the fill level is increased gradually.

6. The method of claim 4, wherein play out is initiated before the fullness has reached a final level.
