Abstract
A method, computer program product, and computing device for modifying a first channel portion of a digital media data file to include at least a first primary watermark. A second channel portion of the digital media data file is modified to include at least a first secondary watermark, wherein the first secondary watermark is the complement of the first primary watermark.
Claims26
A method comprising:
- modifying a first channel portion of a digital media data file to include at least a primary watermark;
- and
- modifying a second channel portion of the digital media data file to include at least a secondary watermark, wherein the first channel portion and the second channel portion are different portions of the same channel and the secondary watermark is a complement of the primary watermark.
A computer program product residing on a non-transitory computer readable medium having a plurality of instructions stored thereon which, when executed by a processor, cause the processor to perform operations comprising:
- modifying a first channel portion of a digital media data file to include at least a primary watermark;
- and
- modifying a second channel portion of the digital media data file to include at least a secondary watermark, wherein the first channel portion and the second channel portion are different portions of the same channel and the secondary watermark is a complement of the primary watermark.
A computing device configured to perform operations comprising:
- modifying, by a watermark embedder utilizing a processor, implemented at least partially in hardware, a first channel portion of a digital media data file to include at least a primary watermark;
- and
- modifying, by the watermark embedder, a second channel portion of the digital media data file to include at least a secondary watermark, wherein the first channel portion and the second channel portion are different portions of the same channel and the secondary watermark is a complement of the primary watermark.
A method comprising:
- modifying a left audio channel portion of a digital media data file to include at least a primary watermark;
- and
- modifying a right audio channel portion of the digital media data file to include at least a secondary watermark, wherein the secondary watermark is a complement of the primary watermark;
- wherein the left audio channel portion and the right audio channel portion are different portions of the audio channel and the primary watermark comprises one or more of a transaction identifier, an asset identifier, a synchronization word, a speed change word, a space, a content provider identifier, and a distributor identifier.
