摘要 |
<P>PROBLEM TO BE SOLVED: To provide a device for encoding capable of handling interlaced image data in two layers respectively when hierarchical encoding is performed. <P>SOLUTION: A hierarchy structuring circuit 10 separates progressive image data S9 to be encoded into interlaced image data S10_1 and S10_2. A lower-layer encoding circuit 12 encodes the interlaced image data S10_2 to generate low-layer encoded data S12. A high-layer encoding circuit 14 encodes the interlaced image data S10_1 based upon low-layer predicted image data L_PREb to generate high-layer encoded data S14. <P>COPYRIGHT: (C)2007,JPO&INPIT |
