Abstract: An apparatus for transmitting data in a digital broadcasting system is disclosed. The apparatus includes: a source encoding unit for encoding data to be transmitted and generating source-coded data; a capacity managing unit for dividing the source-coded data into divided data for a plurality of channels in case that an available data capacity for transmitting the source-coded data does not exist in one channel but sum of available data capacities of the multiple channels can accommodate the source-coded data, and adding header information to the divided data; a channel encoding unit for encoding the divided data according to channel environment and generating channel-coded data; and a transmitting unit for multiplexing, modulating and transmitting the channel-coded data through multiple frequency bands and multiple broadcasting sites.

Abstract: The present invention relates to a Vestigial Side Band (VSB) Digital Television (DTV) in agreement with the DTV standards (A/53) of the Advanced Television System Committee (ATSC), and to a method thereof. More particularly, it provides 4-VSB DTV transceiver that improves reception performance of a receiver by transmitting and receiving dual streams formed of normal data and robust data without increasing average power, regardless of a mixing rate of the normal and robust data. The 4-VSB DTV transceiver of the present research includes an encoding unit for encoding the robust data to b e mapped to one of two groups having 4 levels {-5, -3, 1, 7} and {-7, -1, 3, 5 }.

Abstract: An apparatus and method for transmitting MPEG-4 data synchronized to MPEG-2 data is disclosed. The apparatus for transmitting MPEG-4 data synchronized to MPEG-2 data includes: an object separation unit for extracting MPEG-4 object data from MP4 data, separating meta information from the object data, and generating program information and synchronization information; a conversion unit for converting the MPEG-4 object data to MPEG-4 packets of which data structure is the same as that of MPEG-2 data, based on the program information and synchronization information; and a multiplexing unit for multiplexing the MPEG-4 packets with the MPEG-2 data.
