Coding apparatus and decoding apparatus |
摘要 |
The coding apparatus according to the present invention is a coding apparatus which codes data regarding a moving picture, and includes: a DCT coefficient advanced-coding unit which performs advanced-coding on multivalued data representing a quantized DCT coefficient or a motion vector, so as to reduce the bit length of binary data obtained by binarizing the multivalued data; an advanced-coded coefficient/binary coefficient conversion unit which converts the advanced-coded data obtained by the DCT coefficient advanced-coding unit into the binary data; and an arithmetic coding unit which performs arithmetic coding on the binary data obtained by the advanced-coded coefficient/binary coefficient conversion unit.
