Watermarking of digital video
View Patent ↗Techniques and mechanisms for watermarking of digital video are described herein. According to various embodiments, a request to transmit to a client machine video content based on a video content distribution item may be received. The video content distribution item may be divided into a plurality of video content segments. Designated ones of the video content segments may have a respective plurality of alternate video content segment encodings. Each of the alternate video content segment encodings may include a respective digital watermark. Different digital watermarks may encode different information within the alternate video content segment encodings. One of the respective alternate video content segment encodings may be selected for each of the designated video content segments to create a digital watermarking message to include in the video content. The video content including the selected video content segment encodings may be transmitted to the client machine.
1. A method comprising:
receiving a request to transmit, to a client machine, video content including a digital watermarking message, the video content being based on a video content distribution item, the video content distribution item being divided into a plurality of video content segments, designated ones of the video content segments having a respective plurality of alternate video content segment encodings, each of the alternate video content segment encodings including a respective digital watermark, each of the digital watermarks encoding a respective first binary number, wherein different digital watermarks encode different information within the alternate video content segment encodings;
for each of the designated video content segments, selecting one of the respective alternate video content segment encodings to create the digital watermarking message to include in the video content, wherein the digital watermarking message comprises a second binary number, and wherein the alternate video content segment encodings are selected so that the information encoded in the selected alternate video content segment encodings matches the second binary number; and
transmitting the video content to the client machine, the video content including the selected video content segment encodings.
2. The method recited in claim 1 , wherein the digital watermarks are not perceptible to the human eye.
3. The method recited in claim 1 , wherein the digital watermarking message includes an account identifier identifying a content management account, the client machine being associated with the content management account.
4. The method recited in claim 1 , wherein selected ones of the digital watermarks comprise a respective low frequency image capable of being superimposed on a video frame.
5. The method recited in claim 1 , wherein selected ones of the digital watermarks comprise a low frequency pattern capable of being superimposed on a video frame that has been transformed to a frequency domain.
6. The method recited in claim 1 , wherein the number of alternate video content segment encodings for each video content segment is two raised to the power n for some integer n, and wherein n bits of information may be encoded for each of the video content segments by selecting one of the respective alternate video content segment encodings.
7. A system comprising:
a storage medium operable to store a video content distribution item, the video content distribution item being divided into a plurality of video content segments, designated ones of the video content segments having a respective plurality of alternate video content segment encodings, each of the alternate video content segment encodings including a respective digital watermark, each of the digital watermarks encoding a respective first binary number, wherein different digital watermarks encode different information within the alternate video content segment encodings;
a processor operable to select, for each of the designated video content segments, one of the respective alternate video content segment encodings to create a digital watermarking message to include in video content for transmission to a client machine wherein the digital watermarking message comprises a second binary number, and wherein the alternate video content segment encodings are selected so that the information encoded in the selected alternate video content segment encodings matches the second binary number; and
a communications interface operable to transmit the video content to the client machine, the video content including the selected video content segment encodings.
8. The system recited in claim 7 , wherein the digital watermarks are not perceptible to the human eye.
9. The system recited in claim 7 , wherein the digital watermarking message includes an account identifier identifying a content management account, the client machine being associated with the content management account.
10. The system recited in claim 7 , wherein selected ones of the digital watermarks comprise a respective low frequency image capable of being superimposed on a video frame.
11. The system recited in claim 7 , wherein selected ones of the digital watermarks comprise a low frequency pattern capable of being superimposed on a video frame that has been transformed to a frequency domain.
12. The system recited in claim 7 , wherein the number of alternate video content segment encodings for each video content segment is two raised to the power n for some integer n, and wherein n bits of information may be encoded for each of the video content segments by selecting one of the respective alternate video content segment encodings.
13. One or more non-transitory computer readable media having instructions stored thereon for performing a method, the method comprising:
receiving a request to transmit, to a client machine, video content including a digital watermarking message, the video content being based on a video content distribution item, the video content distribution item being divided into a plurality of video content segments, designated ones of the video content segments having a respective plurality of alternate video content segment encodings, each of the alternate video content segment encodings including a respective digital watermark, each of the digital watermarks encoding a respective first binary number, wherein different digital watermarks encode different information within the alternate video content segment encodings;
for each of the designated video content segments, selecting one of the respective alternate video content segment encodings to create the digital watermarking message to include in the video content wherein the digital watermarking message comprises a second binary number, and wherein the alternate video content segment encodings are selected so that the information encoded in the selected alternate video content segment encodings matches the second binary number; and
transmitting the video content to the client machine, the video content including the selected video content segment encodings.
14. The one or more computer readable media recited in claim 13 , wherein the digital watermarks are not perceptible to the human eye.
15. The one or more computer readable media recited in claim 13 , wherein the digital watermarking message includes an account identifier identifying a content management account, the client machine being associated with the content management account.
16. The one or more computer readable media recited in claim 13 , wherein selected ones of the digital watermarks comprise a respective low frequency image capable of being superimposed on a video frame.
