Adaptive streaming buffering

1. A method, comprising:

receiving streaming media data;

storing the received data in a buffer to fill the buffer;

selectively extracting portions of the received data from the buffer to begin playback of the streaming media data;

analyzing remaining media data in the buffer, to identify a location in the buffer that stores an inactive period in the media data, when the buffer is emptied to a certain percentage of its capacity, where the inactive period comprises a still period in a video portion of the streaming media data and where the still period in the video portion of the streaming media data comprises a period having relatively little change frame by frame in the video portion;

halting playback and partially or fully re-filling the buffer with received streaming media data when the buffer reaches the location in the buffer; and

selectively extracting the received data from the buffer to resume playback of the streaming media data.

2. The method of claim 1 , wherein the inactive period further comprises a silent period in an audio portion of the streaming media data.

3. The method of claim 2 , wherein the silent period comprises a pause in speech contained in the audio portion.

4. The method of claim 1 , wherein the certain percentage of the buffer's capacity comprises 20%.

5. A method, comprising:

filling a buffer with streaming media data;

locating an inactive period in the streaming media data stored in the buffer, where the inactive period comprises a still period in video contained in the streaming media data and where the still period in the video comprises a period having relatively little change frame by frame in the video;

sequentially removing the data from the buffer; and

partially or fully re-filling the buffer with streaming media data when the buffer has been emptied to the located inactive period.

6. The method of claim 5 , wherein the inactive period further comprises a silent period in audio contained in the streaming media data.

7. The method of claim 6 , wherein the silent period comprises a pause in speech in the audio.

8. The method of claim 5 , wherein locating an inactive period in the streaming media data comprises:

locating the inactive period when the buffer has been emptied of media data to a specified percentage of its capacity.

9. The method of claim 8 , further comprising:

playing back the media after the buffer is filled; and

halting playback of the media when the buffer has been emptied of media data to the specified percentage of its capacity.

10. The method of claim 9 , further comprising:

resuming playback of the media data after the buffer is re-filled.

11. A system, comprising:

a buffer;

a communication interface configured to receive streaming media data;

a buffer controller configured to:

store the received data in the buffer to fill the buffer, and

selectively extract the received data from the buffer to begin playback of the streaming media data; and

a buffer analyzer configured to analyze remaining media data in the buffer, to identify a location in the buffer that stores an inactive period in the media data, when the buffer is emptied to a certain percentage of its capacity, where the inactive period comprises a still period in a video portion of the streaming media data and where the still period in the video portion of the streaming media data comprises a period having relatively little change frame by frame in the video portion;

the buffer controller further configured to:

halt playback and partially or fully re-fill the buffer with received streaming media data when the buffer reaches the location in the buffer, and

selectively extract the received data from the buffer to resume playback of the streaming media data.
