Video processing device for embedding time-coded metadata and methods for use therewith
A video processing device includes a content analyzer that receives a video signal and generates content recognition data based on the video signal, wherein the content recognition data is associated with at least one timestamp included in the video signal. A metadata search device generates time-coded metadata in response to content recognition data and in accordance with the at least one time stamp. A metadata association device generates a processed video signal from the video signal, wherein the processed video signal includes the time-coded metadata.
1. A video processing device comprising:
a content analyzer that receives a video signal and generates content recognition data based on the video signal, wherein the content recognition data is associated with at least one timestamp included in the video signal and wherein the content recognition data includes at least one keyword generated by recognizing video content in the video signal as corresponding to the at least one keyword;
a metadata search device, coupled to the content analyzer and at least one external source, that searches for information in response to the content recognition data and generates time-coded metadata in accordance with the at least one time stamp, the content recognition data and that includes the information, wherein the metadata search device searches the at least one external source, based on the at least one keyword, to identify the information; and
a metadata association device, coupled to the metadata search device, that generates a processed video signal from the video signal, wherein the processed video signal includes the time-coded metadata.
2. The video processing device of claim 1 wherein the content analyzer uses speech recognition to generate the content recognition data based on a recognition of speech in audio information included in the video signal.
3. The video processing device of claim 1 wherein the content analyzer uses image recognition to generate the content recognition data based on a recognition of image data included in the video signal.
4. The video processing device of claim 1 wherein the time-coded metadata includes a universal resource locator link to media that includes at least one of: text data, audio data, video data, and image data.
5. The video processing device of claim 1 wherein the time-coded metadata includes at least one of: text data, audio data, video data, and image data.
6. The video processing device of claim 1 wherein the metadata search device generates the information as a plurality of search results and associated relevance data and selects the time-coded metadata by comparing the associated relevance data based on a relevance threshold.
7. The video processing device of claim 1 wherein the metadata association device generates the processed video signal by combining the time-coded metadata with the video signal at time-coded locations in accordance with the at least one time stamp.
8. The video processing device of claim 1 wherein the metadata association device generates the processed video signal by embedding the time-coded metadata as a watermark on the video signal.
9. A method comprising:
generating content recognition data based on a video signal, wherein the content recognition data is associated with at least one timestamp included in the video signal and wherein the content recognition data includes at least one keyword generated by recognizing video content in the video signal as corresponding to the at least one keyword;
searching for information from at least one information source in response to the content recognition data based on the at least one keyword, and generating time-coded metadata in accordance with the at least one time stamp, the content recognition data and that includes the information; and
generating a processed video signal from the video signal, wherein the processed video signal includes the time-coded metadata.
10. The method of claim 9 wherein speech recognition is used to generate the content recognition data based on a recognition of speech in audio information included in the video signal.
11. The method of claim 9 wherein image recognition is used to generate the content recognition data based on a recognition of image data included in the video signal.
12. The method of claim 9 wherein the time-coded metadata includes a universal resource locator link to media that includes at least one of: text data, audio data, video data, and image data.
13. The method of claim 9 wherein the time-coded metadata includes at least one of: text data, audio data, video data, and image data.
14. The method of claim 9 wherein the information includes a plurality of search results and associated relevance data and generating the time-coded metadata includes selecting the time-coded metadata by comparing the associated relevance data based on a relevance threshold.
15. The method of claim 9 wherein the processed video signal is generated by combining the time-coded metadata with the video signal at time-coded locations in accordance with the at least one time stamp.
16. The method of claim 9 wherein the processed video signal is generated by embedding the time-coded metadata as a watermark on the video signal.
