The multimedia bitstream is comprised of variable length codes (VLC) to a large extent. If data hiding is carried out in multimedia compressed domain, VLC are usually chosen as the hidden object. The VLC-coded efficiency is a key factor which can directly affect the method of data hiding. MPEG-I Layer III (MP3) audio is chosen as analytical object in this paper. The VLC-coded rule is obtained by analyzing the VLC-coded efficiency of the MP3 audios. The process of variable length coding in MP3 audio can be understood further passing through the VLC-coded rule. At the same time, it also provides a favorable theoretical base for seeking for effective data hiding methods in MP3 audio compressed domain. |
