Devices, softwares and methods for selectively discarding indicated ones of voice data packets received in a jitter buffer

摘要

Devices, softwares and methods for selectively discarding indicated ones of voice data packets received in a jitter buffer. A comparative discardability code is extracted from one of the stored packets. The code reflects the desirability for discarding the packet relative to the others. A discard decision for the specific packet is made in accordance with the extracted comparative discardability code. Extracting is preferably performed when it is determined to diminish a size of the buffer.
