Method and an apparatus for processing a signal

An apparatus for processing a signal, comprising:

• a receiving unit receiving a maximum number of band and at least one code value of section length;
• a bit number calculating unit calculating a bit number corresponding to the at least one of section length using the maximum number of the band;
• and
• a section length decoding unit obtaining the section length information by decoding the code value of the section length based on the bit number,
• wherein the band corresponds to a scale factor band, wherein a section comprises consecutive bands using a same codebook, and wherein the section length corresponds to a number of the consecutive bands.

A method of processing a signal, comprising:

• receiving a maximum number of band and a code value of at least one section length;
• calculating a bit number corresponding to the code value of the at least one section length using the maximum number of the band;
• and
• generating the code value of the section length by encoding the section length based on the bit number,
• wherein the band corresponds to a scale factor band, wherein a section comprises consecutive bands using a same codebook, and wherein the section length corresponds to a number of the consecutive bands.

A method of processing a signal, comprising:

• receiving a maximum number of band and a code value of at least one section length;
• calculating a bit number corresponding to the code value of the at least one section length using a current remaining number;
• and
• obtaining the section length information by decoding the code value of the section length based on the bit number,
• wherein the current remaining number corresponds to a number of parsing incomplete bands and wherein the current remaining number is determined based on the maximum number and a current accumulative number.
