Abstract: One embodiment is an apparatus having a memory, a controller, and a de-interleaving module. The memory is configured to store portions of a set of interleaved values, where the set of interleaved values correspond to a single application of an interleaving mapping to a set of un-interleaved values. The controller is configured to retrieve each portion from an other memory that stores the set of interleaved values by moving the portion from the other memory to the memory. The de-interleaving module is configured to de-interleave the interleaved values in at least one of the portions to generate a de-interleaved portion such that processing downstream of the de-interleaving module can begin processing the de-interleaved portion before all of the interleaved values in the set of interleaved values are de-interleaved by the de-interleaving module.

Abstract: Adaptive jitter buffer management, e.g., for playout of packetized data transmitted over a network. Playout delay is iteratively adjusted based on changing network traffic characteristics by varying the release threshold in a jitter buffer. The adjustment is carried out by evaluating three quantities: (1) average packet transit time over the network; (2) jitter of the packet transit time; and (3) additional waiting time due to the presence of out-of-sequence packets. This invention reduces negative effects of jitter and/or transmission irregularities, such as late arrival of packets and out-of-sequence packets, while maintaining relatively low playout delay and relatively high quality of service.
