Maintaining clock synchronization in a digital network without continuous transmission
TLDR
In this article, a mobile device consisting of a slave clock, a master clock, and a clock error correction unit (400) is configured to maintain clock synchronization between the slave clock and the master system clock.Abstract:
Embodiments of the present invention provide a mobile device (12) comprising a slave clock (13), a receiver unit (19) for receiving one or more frames from a remote device (11) including a master system clock (14), a transmitter unit (18) for transmitting one or more frames to the remote device (11), and a clock error correction unit (400). The clock error correction unit (400) is configured to maintain clock synchronization between the slave clock (13) and the master system clock (14), and maintain frame alignment for frames transmitted from the transmitter unit (18).read more

Method for achieving synchronous playing of Bluetooth earpieces
TL;DR: In this article, the authors proposed a method for achieving synchronous playing of Bluetooth earpieces, which comprises the steps as follows: intelligent equipment divides an audio into a left channel audio signal and a right-channel audio signal, and separately sends the same to a left Bluetooth earpiece and the right-branch earpiece via an A2DP protocol, wherein the intelligent equipment sends the leftchannel signal and theright channel signal at the start time of a slot, and the duration time of each slot is fixed.

Method and apparatus for TDMA slot synchronization and calibration of master and slave
TL;DR: In this article, a method and an apparatus for TDMA slot synchronization and calibration of a master and a slave is presented, in which the synchronization is realized by directly using the respective clock sources of the master and the slave, without addition of the clock source of the RTC or GPS module, thus reducing the cost and improving the accuracy.
