Transmission apparatus for use in digital broadcasting system to provide e.g. high quality broadcasting service, has transmission processing unit to transmit broadcasting stream generated by multiplexing transport streams, via channel

摘要

The apparatus (100) has base layer and additional layer processing units (101, 102) to convert first and second sets of elementary streams e.g. audio/video signals, corresponding to base and additional layers into packets that are multiplexed to generate base layer and additional layer transport streams, respectively. A multiplexing unit (160) multiplexes the transport streams to generate a broadcasting stream e.g. digital multimedia broadcasting (DMB)transport stream. A transmission processing unit (170) transmits the broadcasting stream via a transmission channel. The base layer and additional layer transport streams are MPEG-2transport streams. Independent claims are also included for the following: (1) a method for carrying out transmission in a digital broadcasting system (2) a receiving apparatus for a digital broadcasting system (3) a method for carrying out reception in a digital broadcasting system.
