Abstract:
Methods and apparatus for performing variable block length watermarking of media are disclosed. Disclosed example apparatus include means for selecting a first frequency from a set of frequencies based on a first symbol in a code, and for selecting a first block size based on the first symbol and the code, a combination of the first block size and the first frequency to represent the first symbol. Disclosed example apparatus also include means for synthesizing a code frequency according to the first block size and the first frequency. Disclosed example apparatus further include means for combining the code frequency with a first block of input audio samples of the audio having the first block size to form a block of encoded audio samples encoded with the first symbol, the code frequency and the first block of input audio samples to overlap in time.

Claim (Index 4):
The apparatus of  claim 1 , wherein the first symbol encoded in the block of encoded audio samples is detectable at the first frequency when the block of encoded audio samples is decoded using the first block size and the first symbol is not detectable at the first frequency when the block of encoded audio samples is decoded using a second block size different than the first block size.
