Study on a new time transfer method by digital satellite TV signal broadcasting

This paper is dedicated to studying on the new method of digital satellite TV time transfer service by DVB-S protocol. We present a new way that takes the advantage of pilot carrier information and symbol information to provide time transfer service. Because of the synchronization characteristics of symbol frame, we can insert time code information in the blank position of the pilot carrier information periodically. In the mean time, a kind of simplified data encoding method to show the complete time code message was introduced.
