METHOD FOR TRANSMITTING/RECEIVING IN DIGITAL MULTIMEDIA BROADCASTING SYSTEM AND APPARATUS THEREOF

摘要

PURPOSE: A transmission and reception method in a digital multimedia broadcasting system and an apparatus thereof are provided to divide one transmission stream into a plurality of streams in consideration of effective data rate in enhancement layer and effective data transmission rate in essential layer and transmit the transmission stream, thereby performing divided transmission of the transmission stream adaptively according to transmission environment. CONSTITUTION: An enhanced layer processor(12) comprises an enhanced layer multiplexer(121), a stream dividing unit(122) and an enhanced layer channel encoder(123). The enhanced layer multiplexer outputs an enhanced layer TS(Transport Stream) by multiplexing of base streams of the enhancement layer. The stream dividing unit divides the enhancement layer transport stream into a plurality of streams. The enhanced layer channel encoder performs channel encoding of divided enhanced layer TS.
