Abstract
A multimedia bitrate adaption method for individual users wherein only a set of predetermined bitrates may be selected as the multimedia bitrate of the user. The predetermined bitrates are quantized into exponentially distributed levels, and the users' experiences corresponding to the predetermined bitrates are with the same intervals, thereby increasing the service capacity and improving user satisfaction.
Claims13
A method for adapting a multimedia data bitrate applied in a multimedia data transmission system, comprising:
- estimating an available bandwidth of a user;
- determining a range of available bandwidth between two adjacent predetermined bitrates from several predetermined bitrates;
- and
- setting the multimedia data bitrate for the user to be the smaller predetermined bitrate of the two adjacent predetermined bitrates;
- wherein the predetermined bitrates are exponentially distributed.
A voice over internet protocol (VoIP) data bitrate adaption method applied in a multimedia data transmission system, comprising:
- estimating an available bandwidth of a user;
- determining a range of available bandwidth between two adjacent predetermined bitrates from several predetermined bitrates;
- and
- setting a VoIP data bitrate of the user to be the smaller predetermined bitrate of the two adjacent predetermined bitrates;
- wherein the predetermined bitrates are exponentially distributed.
