    摘要: A jitter buffer controller (110) allows the depth of the jitter buffer (113) to be adjusted dynamically according to the varying jitter of the current sequence. The jitter buffer controller (110) maintains a cache (109) of previous jitter values. This cache contains exponentially averaged values that represent the long-term behavior of specific destination's jitter characteristics, i.e., a jitter characteristic memory. These values are used to initialize the jitter buffer's depth. The jitter cache prevents the buffer's depth from being initialized with an arbitrary value that disregards the specific destination's jitter characteristics.
