摘要： 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.

摘要： The present invention relates to a method and an apparatus for transmitting and receiving an ultra-high definition broadcasting signal for high dynamic range representation in a digital broadcasting system. An apparatus for receiving an ultra-high definition broadcasting signal according to an embodiment of the present invention comprises: a receiving unit for receiving the ultra-high definition broadcasting signal including ultra-high definition broadcasting contents and high dynamic range metadata, the high dynamic range metadata indicating brightness information represented in the ultra-high definition broadcasting contents and information on a method for converting the ultra-high definition broadcast contents to be adapted to a display environment of the receiving apparatus; a decoder for decoding the received ultra-high definition broadcasting contents; and a reproduction unit for reproducing the decoded ultra-high definition broadcasting contents.
