CODED DATA EDITING DEVICE AND DATA DECODER

摘要

PROBLEM TO BE SOLVED: To efficiently edit coded data by making an amount of data stored in a buffer at a head of a segmented part of a coding data string in matching with an amount of data stored in a buffer just after a segmented part at a head of a coding data string. SOLUTION: A buffer occupancy amount discrimination section 8 at first reads an occupied amount A of a VBV buffer for a picture at a head of a coded data string segmented by a parameter recording section 7. Let the segmented coded data string be a GOP (picture group) in the coded data, the occupied amount A of the VBV buffer at head 18-picture is read. Succeedingly an occupied amount B of the VBV buffer of a picture just after the segmented coding data string is read. Then the discrimination section 8 compares the occupied amounts A, B of the VBV buffer. In the case of A>B, pictures are inserted between the segmented data by the difference between the A and B. In the case of A
