Abstract

Many multimedia data hiding systems demand either multiple bits or multiple sets of data to be embedded. Thispaper examines the modulation and multiplexing techniques for accomplishing the task of extending the basic single-
bit embedding to multiple-bit embedding. Amplitude modulo modulation, orthogonal/bi-orthogonal modulation,
and TDMA or CDMA type modulation/multiplexing are discussed and compared. Several examples are included to
demonstrate the use of such techniques in practical designs.
