1. A decoder, comprising:
a central processing unit (CPU) configured to:
decode a first band signal of encoded data of a tactile signal, wherein
the first band signal corresponds to a first frequency band in the tactile signal,
the encoded data is based on an encoding result of the first band signal and tactile intensity information, and
the tactile intensity information includes a flag;
determine that the flag indicates one of a first value or a second value;
acquire, based on the determination that the flag indicates the first value, a total value of tactile intensities of a plurality of frequencies of a second frequency band in the tactile signal,
wherein the second frequency band is different from the first frequency band;
acquire, based on the determination that the flag indicates the second value, a tactile intensity of a major frequency of the plurality of frequencies,
wherein an amplitude of the major frequency is equal to or greater than a specific threshold;
generate a second band signal based on one of the total value of the tactile intensities of the plurality of frequencies or the tactile intensity of the major frequency,
wherein the second band signal corresponds to the second frequency band in the tactile signal; and
synthesize the first band signal and the second band signal.
