1. An image decoding device which decodes an encoded bit stream formed by encoding images for each object, comprising:
display speed information decoding means for decoding a header information area of the encoded bit stream to restore display
speed information to indicate a number of VOPs displayed per unit time, the display speed information being included as a
codeword in the header information area for a layer that is above a VOP layer and comprises a plurality of VOPs, wherein for
the layer above the VOP layer, the header information area is separate from the data area; and
control means for controlling the reconstruction of said encoded images encoded for each object, based on said object display
speed information restored by decoding.
