1. A decoding method comprising:
while inter-layer prediction is enabled, reconstructing a second layer reference picture from a first layer reference picture of a decoder picture buffer of a scalable multi-layered stream and from data decoded from a second layer of the scalable multi-layered stream and storing the reconstructed second layer reference picture in the decoder picture buffer;
decoding a flag indicating whether to display the reconstructed second layer reference picture; and
reconstructing a picture block of a subsequently decoded picture at least from the reconstructed second layer reference picture.
