Abrégé
(EN)
The present invention relates to a method of receiving broadcast signals and an apparatus for receiving broadcast signals. The apparatus includes a receiving unit (110) configured to receive a broadcast signal, a demodulator (120) configured to demodulate the broadcast signal, a demultiplexer (130) configured to demultiplex the broadcast signal, a storage device (160) configured to store a replacement segment to replace a specific portion of a broadcast stream, and segment-related information describing a replaceable segment included in a broadcast stream, from the demultiplexed signal, a controller (320) configured to control uploading the stored replacement segment or downloading the replacement segment and to insert the stored replacement segment into the broadcast stream according to the segment- related information; and a decode (200) configured to decode a broadcast stream.
