PURPOSE: A transmission system for providing a hybrid service, a receiving device thereof and a service providing method thereof are provided to selectively provide the hybrid service using an information describer. CONSTITUTION: A first signal processing unit (230) processes reference data detected from a demultiplexer unit. If a service is determined as a hybrid service by an information describer, a control unit (240) controls a second receiving unit to access a source device corresponding to supplementary data reference information. A second signal processing unit (260) receives a second signal including additional data from the source device through an IP communications network. The second signal processing unit processes the additional data. An output unit (270) synchronizes the reference data processed in the first signal processing unit and the additional data processed in the second signal processing unit and outputs synchronized data of the reference data and the additional data.

PURPOSE: A method for transmitting and receiving an ultra high definition broadcast in a digital broadcasting system and an apparatus thereof are provided to transmit and receive 'a broadcasting service of an ultra high definition or a high capacity which has a large transmission band width' in the digital broadcasting system by using multiple associated transmission streams. CONSTITUTION: A receiver determines 'whether a received transport stream (TS) includes information about an associated relationship with a different transmission stream or not' (S610). The receiver analyzes information about the associated relationship from the transmission stream and determines 'whether the transmission stream includes information about a program which is provided by associating with the different transmission stream or not' (S620,S630). The receiver extracts information about the program from the transmission stream and obtains the program based on the program information (S640,S650).
