Abstract: The present invention provides an apparatus for transmitting broadcast signals, an apparatus for receiving broadcast signals and methods for transmitting and receiving broadcast signals. An apparatus for transmitting a broadcast signal including multimedia content using a broadcast network includes: an encoder configured to generate signaling information, wherein the signaling information indicates whether the multimedia content is to be transmitted in real time; a transmission block generator, if the signaling information indicates real-time transmission of the multimedia content, configured to divide a file contained in the multimedia content into at least one transmission block (TB) indicating a data unit that is independently encoded and transmitted; and a transmitter configured to transmit the transmission block (TB). Accordingly, the apparatus can reduce a total time needed when multimedia content is acquired and then displayed for a user.
