Method of allocating payload bits of a watermark

摘要

A method of dynamically allocating payload bits in a watermarking system ( 10 ) is provided. The method including steps of: (a) determining one or more parameters to be conveyed in bits of a payload to be included in watermark information for embedding in programme content; (b) dynamically allocating the bits to corresponding of the one or more parameters so as to represent the one or more parameters in the payload; (c) including the payload in the watermark information; and (d) embedding the watermark information including the payload into the programme content. Such dynamic allocation of payload bits is capable of providing more effective use of payload capacity.
