    Abstract: There is provided a method of allocating optimal payload space in a watermarking system. The method includes steps of: (a) obtaining identification parameters relating to programme data content (PC), said identification parameters including at least one or more user identifiers (UID) and one or 5 more programme content identifiers (CID); (b) storing said identification parameters (UID, CID) in one or more databases (30); (c) generating one or more transaction numbers (nTR) capable of being uniquely mapped to corresponding identification parameters (UID, CID) stored in the one or more 10 databases (30); and (d) generating watermark information for carrying said one or more transaction numbers (nTR) and embedding said watermark information as an optimized payload (OPL) into said programme data content (PC) to generate corresponding watermarked data content (WPC).

    Abstract: The acoustic signal transmission includes electrically synthesizing an audible sound signal and an insertion signal to generate a synthesized sound electrical signal at the sending side, transmitting the synthesized sound electrical signal, and extracting the insertion signal form the synthesized sound electrical signal at the receiving side. The extracted signal may be used for controlling machines or for transmitting information. The acoustic signal represented by the synthesized sound electrical signal can be heard by human ears in the same way as the audible sound signal, while the synthesized insertion signal cannot be detected by human ears. The synthesized sound electrical signal can be transmitted as a sound wave in air space, as electrical signals through a transmission line or as radio signals such as infrared and electromagnetic waves. The synthesized sounds may also be transported or distributed by recording on recording media such as compact disc and DVD.

    Abstract: A high-quality signal, for example a unity-bit coded (DSD) audio signal having a 2.822 MHz bit rate (fs1) is converted to a lower sample rate (fs3) PCM signal by means of a sample rate converter (102). The watermark is embedded at the lower sample rate by a conventional watermark embedder (101) which is capable of handling signals at this lower rate. The watermark (WM) is not otherwise available. It is subsequently retrieved by subtracting (103) the unwatermarked signal from the watermarked signal, and up-sampled (104) to an intermediate sampling rate (fs2). The DSD signal is converted (110) to a PCM signal at said intermediate sample rate. The retrieved watermark is then added (107) to the PCM signal and the watermarked PCM signal is back-converted (120) to a unity-bit coded DSD signal. In a preferred embodiment, the arrangement includes a compensation circuit (105) which compensates the information signal Xnull for any (e.g. non-linear) operations performed by the embedder (101) so as to minimize the estimated watermark (WMnull). The compensation circuit re-introduces said operations in the DSD domain by controlling parameters such as scaling (106, 109) and time shifting (108).
