Abstract:
An encoding device (100) that comprises a circuit (160) and memory (162). The circuit (160) performs: a step in which the memory (162) is used to reference second filter information that has been associated with a second picture and thereby determine first filter information that is for applying an adaptive loop filter to a first picture; and a step in which the determined first filter information is used to apply the adaptive loop filter to the first picture. When the NAL unit type of the first picture is a prescribed NAL unit type, the circuit (160) prohibits referencing, as the second filter information, third filter information that has been associated with a third picture that has the same temporal ID as the first picture.
