A method comprising: receiving a plurality of Transport Streams (TSs) from an Ultra High Definition (UHD) transmission or high-capacity broadcasting transmission, including a first TS through a transport channel; determining whether the first TS includes information about an association relation with other TSs of the plurality of TSs by extracting a Program Associate Table (PAT) from the first TS to determine whether a Packet IDentifier (PID) value of a Network Information Table (NIT) packet includes the information about the association relation with the other TSs on the basis of the PAT; in response to determination that the information about the association relation with the other TSs is included, analyzing the information about the association relation with the other TSs from the NIT of the first TS; determining whether the first TS includes information about a program provided in the association relation with the other TSs based on the information about the association relation with the other TSs, wherein determining whether the first TS includes the information about the program includes determining whether an IDentifier (ID) of the first TS is identical with an Identifier (ID) of a second TS including the information about the program; extracting the information about the program from the first TS and the second TS of the other TSs when the NIT of the first TS indicates an association relation with the second TS; and obtaining the program based on the extracted information about the program.
