Abstract
The present invention relates to a broadcast signal transmission/reception method and an apparatus therefor for providing a HDR broadcast service. The broadcast signal transmission method according to one embodiment of the present invention comprises the steps of: generating LDR video data by converting the dynamic range of HDR video data; generating residual information; generating a base layer stream by encoding the generated LDR video data; generating an enhancement layer stream by encoding the generated residual information; generating signaling information including information for decoding the enhancement layer stream; multiplexing the generated base layer stream, the enhancement layer stream and the signaling information into one broadcast stream; generating a broadcast signal including the multiplexed broadcast stream; and transmitting the generated broadcast signal.
