Abstract

A method of controlling an adaptable jitter buffer in accordance with the present invention detects a context description of data handled by the adaptable jitter buffer. Thereafter it is determined whether the detected context description is equal to a predetermined context description. If not, jitter buffer adaptation proceeds as normal. Otherwise it is determined whether the current target buffer depth is too low for the detected context description. If not, the target buffer depth is frozen to the current value. Otherwise it is increased and frozen at a higher value that is compatible with the detected context description.
