Abstract
Systems, methods, and devices synchronize data streams by hashing received data frames to generate a sequence of hash values, comparing the generated hash value sequence to a hash value sequence received in a control stream, and processing data frames when the hash value sequences match. A source device and multiple receiver devices may synchronize audio data encoded in data frames, applying a hash function to each data frame to generate a first sequence of hash values, transmitting the data frames on a first channel and the first sequence of hash values on a control channel, receiving the data frames and the first sequence of hash values in the receiver devices, applying the hash algorithm to received data frames to generate a second sequence of hash values, comparing the first and second sequences of hash values, and processing data frames when the first and second sequences of hash values match.
