Abstract
The apparatus for decoding a digital signal includes a composite picture forming unit for forming a composite picture from a first digital video signal and a second digital video signal. The first digital video signal includes inter-coded picture data. A down-converter receives a third digital video signal, and outputs the third digital video signal to the composite picture forming unit as the first digital signal in a first mode. However, the down-converter down-converts the third digital video signal into a fourth digital video signal in a second mode, and outputs the fourth digital video signal to the composite picture forming unit in the second mode. A memory stores the anchor pictures output from the composite picture forming unit, and a motion compensator generates the second digital signal based on the stored anchor pictures.
