Dynamic buffer settings for media playback
First Claim
1. A method for dynamically improving responsiveness and robustness of media playback on a media player, the method comprising:
- receiving a media stream;
configuring one or more storage parameters of a jitter buffer, the one or more storage parameters including at least one of a preroll duration value and a starvation threshold, the preroll duration value representing a minimum amount of first data from the media stream that is stored in the jitter buffer in order to play the media stream, the starvation threshold representing a minimum amount of second data from the media stream stored in the jitter buffer in order to prevent play-out of the second data in the jitter buffer;
playing the media stream;
monitoring a data storage state of the jitter buffer; and
adjusting the one or more storage parameters of the jitter buffer based upon the data storage state.

Abstract
Improved responsiveness and reduced latency of media playback on a media player is achieved by dynamic adjustment of storage parameters for the jitter buffer in the media player. Decreasing the size of the jitter buffer to a smaller constant value may provide acceptable, starvation-free playback in many cases. Playback of more demanding files requiring more buffered data for decode are addressed by dynamic adjustment of the jitter buffer parameters. An algorithmic or heuristic process is used to dynamically set the size of the jitter buffer before and during media playback. The jitter buffer size and/or preroll duration may be adjusted based upon the quality of playback experience. If playback starves, the jitter buffer size, starvation threshold, and/or preroll duration is increased before rebuffering and resuming playback. If the jitter buffer remains above a defined threshold for a given period of time, the jitter buffer size and/or preroll duration may be decreased, improving the responsiveness of startup and seek and trick mode operations.
