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.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . 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.   
     
     
         2 . The method of  claim 1  wherein 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. 
 
     
     
         3 . The method of  claim 1  wherein the first channel portion of the digital media data file comprises:
 a left audio channel. 
 
     
     
         4 . The method of  claim 1  wherein the second channel portion of the digital media data file comprises:
 a right audio channel. 
 
     
     
         5 . The method of  claim 1  wherein the second channel portion of the digital media data file comprises:
 a left audio channel. 
 
     
     
         6 . The method of  claim 1  wherein first channel portion of the digital media data file comprises:
 a right audio channel. 
 
     
     
         7 . The method of  claim 1  wherein the digital media data file is selected from the group consisting of:
 an audio file and a digital audio portion of a digital audio-visual file. 
 
     
     
         8 . The method of  claim 1  wherein the digital media data file includes at least a third channel portion. 
     
     
         9 . 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.   
     
     
         10 . The computer program product of  claim 9  wherein 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. 
 
     
     
         11 . The computer program product of  claim 9  wherein the first channel portion of the digital media data file comprises:
 a left audio channel. 
 
     
     
         12 . The computer program product of  claim 9  wherein the second channel portion of the digital media data file comprises:
 a right audio channel. 
 
     
     
         13 . The computer program product of  claim 9  wherein the second channel portion of the digital media data file comprises:
 a left audio channel. 
 
     
     
         14 . The computer program product of  claim 9  wherein the first channel portion of the digital media data file comprises:
 a right audio channel. 
 
     
     
         15 . The computer program product of  claim 9  wherein the digital media data file is selected from the group consisting of:
 an audio file and a digital audio portion of a digital audio-visual file. 
 
     
     
         16 . The computer program product of  claim 9  wherein the digital media data file includes at least a third channel portion. 
     
     
         17 . 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.   
     
     
         18 . The computing device of  claim 17  wherein 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. 
 
     
     
         19 . The computing device of  claim 17  wherein the first channel portion of the digital media data file comprises:
 a left audio channel. 
 
     
     
         20 . The computing device of  claim 17  wherein the second channel portion of the digital media data file comprises:
 a right audio channel. 
 
     
     
         21 . The computing device of  claim 17  wherein the second channel portion of the digital media data file comprises:
 a left audio channel. 
 
     
     
         22 . The computing device of  claim 17  wherein the first channel portion of the digital media data file comprises:
 a right audio channel. 
 
     
     
         23 . The computing device of  claim 17  wherein the digital media data file is selected from the group consisting of:
 an audio file and a digital audio portion of a digital audio-visual file. 
 
     
     
         24 . The computing device of  claim 17  wherein the digital media data file includes at least a third channel portion. 
     
     
         25 . 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.   
     
     
         26 . The method of  claim 25  wherein the digital media data file is selected from the group consisting of:
 an audio file and a digital audio portion of a digital audio-visual file.
