<p>A weighting-factor mode determining part determines, based on the value of a graph ";AFF" indicating whether to switch the field and frame on a block-by-block basis, whether the mode is a field mode or a frame mode, and notifies switches and a multiplexing part of the mode. The switches perform selection of field/frame in accordance with the notified mode. A field weighting-factor encoding part or a frame weighting- factor encoding part, when selected, performs a weighting-factor encoding.</p> |
