Document Type and Number:
Japanese Patent JP3380981
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To perform normal decoding even from halfway of a coded bit stream by encoding an image, including header of an upper layer in a header of a lower layer and outputting the coded bit stream. SOLUTION: A VLC(variable length coding) device 6 forms a coded bit stream by arranging information that should originally be arranged at respective headers of VS, VISO, VO, VOL, GOV and VOP and further arranging a variable length coded result of image data which is supplied from a quantizer 5 and outputs it to a transmission buffer 7. Also, the device 6 outputs the information arranged at each header of the VS, VISO, VO and VOL which are upper layers than the GOV to a buffer 16 and stores it in it. After that, the device 6 reads information of each header of the VS, VISO, VO and VOL which are upper layers than the GOV stored in the buffer 16 at the time of outputting a GOV header, inserts it into a prescribed position of the GOV header and outputs it.
