Title:
CLOCK SYNCHRONIZATION WHEN SWITCHING BETWEEN BROADCAST AND DATA TRANSMISSION MODES
Document Type and Number:
WIPO Patent Application WO/2019/083948
Kind Code:
A3
Abstract:
A communication system allows for clock synchronization between a transmitter and a receiver when switching from transmission of an analog signal to transmission of a digital signal. The system uses clock synchronization during transmission of the digital signal, but the clock synchronization may be lost when switching to transmission of an analog signal. A digital clock synchronization is embedded in the analog signal so that the clock synchronization between the transmitter and the receiver may be reestablished upon switching to a digital signal without any delay in transmission of the digital signal.
