One claim recites a method including: receiving data representing video, the data comprising at least first digital watermarking embedded therein; decoding the first digital watermarking embedded in the data to obtain a first identifier; and then converting the data into low bandwidth Internet video; and embedding at least the first identifier with digital watermarking into converted low bandwidth Internet video, the identifier identifying at least the video. Of course, other combinations are described, enabled and claimed as well.

Claims

1. A method comprising:

receiving data representing video, the data comprising at least first digital watermarking embedded therein;

then converting the data into low bandwidth Internet video;

utilizing a watermarking embedding key and robustness parameters, embedding at least the first identifier, obtained from said decoding the first digital watermarking embedded in the data, with second digital watermarking into converted low bandwidth Internet video, the identifier identifying at least the video.

6. The apparatus of claim 5 in which the processor is further programmed for embedding a second identifier in the converted low band width Internet video data with third digital watermarking.

7. The apparatus claim 6 wherein the second identifier is associated with a transaction.

8. The apparatus of claim 6 wherein the second identifier is associated with a data conversion.

9. A non-transitory computer readable medium comprising instructions stored thereon that when executed cause a processor to perform the following:

controlling data representing video, the data comprising at least first digital watermarking embedded therein;

then

converting the data into low bandwidth Internet video;

utilizing a watermarking embedding key and robustness parameters, embedding at least the first identifier, obtained from said act of decoding the first digital watermarking embedded in the data, with second digital watermarking into converted low bandwidth Internet video, the first identifier identifying at least the video.

10. The non-transitory computer readable medium of claim 9 in which the instructions that when executed further cause the processor to preform:

embedding a second identifier in the converted low bandwidth Internet video data with third digital watermarking.

11. The non-transitory computer readable medium of claim 10 in which the second identifier is associated with a transaction.

12. The non-transitory computer readable medium of claim 10 in which the second identifier is associated with a data conversion.
