Abstract: In various embodiments, a corpus of codecs may be correlated with different, partially overlapping ranges of transmission characteristics. As channel conditions degrade or improve, the system may select a new codec with which to continue the connection based upon the corresponding overlapping range. Codecs may not be switched immediately when the transmission characteristics enter overlapping ranges, to avoid degrading the user's experience. If the characteristics remain in the overlap, or manifest a likely progression toward another region, then the transition may be effected.

Abstract: Various of the disclosed embodiments improve encoding during a network call, such as a Voice Over Internet Protocol (VOIP) connection, by adjusting the size of a data communications packet (“packet”). Particularly, given a corpus of codecs with which to encode data, the embodiments may identify a packet size based upon a common multiple of each codec's minimum raw data size. The packet size may be selected to accommodate the inclusion of data encoded in each codec format, as well as error correction code data, and codec transition commands. The packet size may be tailored to trade off measured latency and data efficiency.
