A Design of TS Distribution Synchronization Method for DTMB SFN System

Abstract:

A single frequency network (SFN) based on the DTMB (Digital Television Terrestrial Broadcasting System) terrestrial digital television (DTV) system normally causes interference among signals from multiple transmitters in the network. These transmitters should broadcast the same program at the same frequency simultaneously in the service area. To meet the SFN network construction requirements in complex transport situation, TS distribution networks synchronization is one of the most important foundations. A design was proposed to insert into each MPEG-TS (SIP) packet with one absolute timestamp in the SFN adapter, which was proved to be valuable insuring the synchronization of the SFN TS distribution through field-test in Ningxia DTMB network.
