1. A transmission method, performed by a transmitter, for transmitting contents to a receiver, the transmission method comprising:
determining, based on control information, whether a first encoding scheme to generate a first codeword or a second encoding scheme to generate a second codeword is used for encoding, a first parity check matrix of the first encoding scheme being different from a second parity check matrix of the second encoding scheme, a first length of the first codeword being smaller than a second length of the second codeword;
encoding an information data sequence according to the determined encoding scheme to generate an encoded data sequence; and,
transmitting the encoded data sequence to the receiver, that decodes the encoded data sequence, wherein
the information data sequence includes multiplexed data in which at least two contents are multiplexed, the at least two contents including a compressed video content, and
the information data sequence includes a High Dynamic Range (HDR) indicator indicating that the compressed video content is to be decompressed in the receiver according to HDR video compression.
