APPARATUS AND METHOD OF SYNCHRONIZATION AMONG PLURALITY OF ASSOCIATED TRNASFER STREAMS IN DIGITAL BROADCASTING SYSTEM

摘要

PURPOSE: An apparatus and a method for synchronizing a plurality of transport streams are provided to prevent overflow and underflow of transport streams in a digital broadcasting system. CONSTITUTION: A basic layer processing unit(101) generates a basic layer transport stream. An additional layer processing unit(102) generates a dummy packet which does not have effective data. A system synchronizing unit(103) generates first program clock reference information and second PCR information for the dummy packet based on one system time clock.
