A decoder for decoding compressed data obtained through compression of digital data based on a high efficiency coding technique. The compressed data is processed in units of a predetermined amount of data and the predetermined data unit contains information indicative of a first point of time at which the data unit is to be output from the decoder. The decoder includes a decoding circuit, a time measuring circuit for measuring a second point of time as a timing reference at which the decoding circuit outputs the data, a comparator for comparing a value of the first point of time with a value of the second point of time and/or for comparing a difference value corresponding a subtraction of the value of the second point of time from the value of the first point of time with a predetermined value, and a controller, when the difference value is larger than a predetermined value, for controlling the decoding circuit to cause no output of the data decoded from the data unit including information indicative of the first point of time and to process a next unit.
