Title: APPARATUS FOR TRANSMITTING BROADCAST SIGNALS, APPARATUS FOR RECEIVING BROADCAST SIGNALS, METHOD FOR TRANSMITTING BROADCAST SIGNALS AND METHOD FOR RECEIVING BROADCAST SIGNALS
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. A broadcast signal transmission apparatus includes a delivery object generator configured to divide a file into at least one delivery object corresponding to a part of the file, a signaling encoder configured to encode signaling information including metadata for the delivery object, the signaling information including real time information indicating whether the at least one delivery object is transmitted in real time via a unidirectional channel using at least one layered coding transport (LCT) packet, and a transmitter configured to transmit the at least one delivery object and the signaling information. It is possible to reduce a total time consumed for obtaining multimedia content and displaying the multimedia content for a user.
