Abstract
A jitter buffer controller allows the depth of the jitter buffer to be adjusted dynamically according to the varying jitter of the current sequence. The contents of the jitter buffer are examined during a transmission. If the delay or average delay within the buffer drops to a predetermined threshold, then the size or depth of the jitter buffer is increased.
Claims10
A telecommunications method, comprising:
- setting a jitter buffer occupancy threshold;
- receiving data into a jitter buffer;
- and
- adjusting a depth of said jitter buffer if said jitter buffer occupancy threshold is crossed, said adjusting comprising increasing or decreasing periods of silence.

A telecommunications system, comprising:
- a packet network;
- and
- a jitter buffer system, said jitter buffer system including a jitter buffer, a jitter buffer cache, and a jitter buffer controller, said jitter buffer controller configured to monitor packets arrivals and adjust a depth of said jitter buffer if a jitter buffer occupancy crosses a jitter buffer occupancy threshold, said jitter buffer controller adjusting said depth by increasing or decreasing periods of silence.
A telecommunications device, comprising:
- a jitter buffer;
- a jitter buffer cache configured to store one or more values related to time intervals between packets;
- and
- a jitter buffer controller configured to adjust a depth of said jitter buffer by increasing or decreasing periods of silence based on said one or more values stored in said jitter buffer cache.
