Abstract
Provided are a method and apparatus for transmitting and receiving broadcast and communication combined service information. The method of receiving broadcast and communication combined service information includes receiving a broadcast signal comprising receiving control information for communication service information to be serviced in association with broadcast service information to be broadcast at a specific instant of time, and broadcast service information to be broadcast before the specific instant of time; analyzing the receiving control information and requesting and receiving communication service information corresponding to the analysis result; and receiving a broadcast signal including the broadcast service information to be broadcast at the specific instant of time, synchronizing the received broadcast service information with the received communication service information, and displaying the synchronized result. Accordingly, it is possible to provide a broadcast and communication combined service by displaying previously received communication service information in synchronization with broadcast service information.
