ABSTRACT:
This invention aims to form hierarchies of coded moving picture data in a simple method or apparatus. An I, P and B separator separates I, P and B picture data from coded moving picture data. A first to a third header/low/high separator separate headers and low and high DCT data components of the separated I, P and B picture data, and hierarchy forming means assigns the outputs of the separators for a 1-st to a 6-th hierarchy by supplying the outputs to packetizers therefor. The packetizers packetize the assigned data, and send out the packetized data on communication lines for the 1-st to 6-th hierarchies. For example, low frequency components of I picture data are provided as the 1-st hierarchy, high frequency components of I picture data are provided to the 2-nd hierarchy, low frequency components of P picture data are provided as the 3-rd hierarchy, high frequency components of P picture data are provided as the 4-th hierarchy, low frequency components of B picture data are provided as the 5-th hierarchy, and high frequency components of P picture data are provided as the 6-th hierarchy.
