ABSTRACT:
Selective encryption for object data such that objects having copyrights to-be-protected are encrypted. There are provided a plurality of data compression devices for compressing respective object data respectively corresponding to a plurality of objects which compose a scene, a multiplexor for multiplexing scene description data and compressed object data to produce a multiplexed bit stream MB, a scrambler for encrypting (scrambling) individual streams corresponding to the objects having copyrights to-be-protected in the multiplexed bit stream MB, to produce an encrypted bit stream SB, for outputting the encrypted bit stream SB to a data storage medium or a data transmission medium.
