Abstract
An encoder includes circuitry and memory coupled to the circuitry. In operation, in the case where a video parameter set is used for encoding a video, the circuitry writes a first parameter into the video parameter set. The first parameter indicates the maximum number of one or more temporal sublayers in a layer set unit. The circuitry writes a second parameter into a sequence parameter set. The second parameter indicates the maximum number of one or more temporal sublayers in a sequence unit. In the case where the video parameter set is used for encoding the video, the second parameter is limited to less than or equal to the first parameter. In the case where the video parameter set is not used for encoding the video, the second parameter is limited to less than or equal to a fixed value.
