    摘要: 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.

    摘要: The systems, methods, and devices of the various embodiments provide call control information from a mobile phone to another device by moving the functionality enabling the separation of call control commands from audio data off the mobile phone. The various embodiments handle the separation of call control commands from audio data at an ear piece or other peripheral device, such as a personal hub, which is part of a multiple subscriber device system. The various embodiments enable the standard Bluetooth® Hands-Free Profile to be used by a multiple subscriber device system to interact with a mobile phone.
