Protecting commercials within encoded video content
View Patent ↗In one embodiment, a method comprises identifying an identifiable video object from a video picture of a digital video having video content and commercial content, the video picture contained within the video content; encoding the identifiable video object as a video overlay object; encoding the commercial content based on generating a first key frame, and storing the video overlay object within the first key frame as an object that is not displayed as part of the commercial content; and encoding the video picture based on generating a second key frame that includes a default video object in place of the identifiable video object, the default video object including an overlay reference to the video overlay object within the first key frame, wherein unavailability of the video overlay object during rendering of the second key frame causes display of the default video object to visually corrupt the video picture.
1. A method comprising:
identifying, by an apparatus, an identifiable video object from a video picture of a digital video having video content and commercial content, the video picture contained within the video content;
encoding by the apparatus the identifiable video object as a video overlay object;
encoding by the apparatus the commercial content based on generating a first key frame containing the commercial content, and storing the video overlay object within the first key frame as an object that is not displayed as part of the commercial content; and
encoding by the apparatus the video picture based on generating a second key frame that includes a default video object in place of the identifiable video object, the default video object including an overlay reference to the video overlay object within the first key frame, wherein the commercial content is protected based on an unavailability of the first key frame containing the video overlay object, during rendering of the second key frame, causing display of the default video object to visually corrupt the video picture.
2. The method of claim 1 , wherein availability of the video overlay object, during rendering of the second key frame, causes the video picture to be displayed with the identifiable video object based on the overlay reference causing display of the video overlay object overlying the default video object.
3. The method of claim 2 , wherein the encoding of the video picture includes inserting, as the default video object, an advertisement message associated with the commercial content, the advertisement message displayed based on the unavailability of the video overlay object during rendering of the second key frame.
4. The method of claim 2 , wherein the default video object contains uncoded data and no image data.
5. The method of claim 2 , wherein the video overlay object includes first color information for rendering the identifiable video object according to respective colors within the identifiable video object, and the default video object includes second color information for rendering the identifiable video object according second colors substantially distinct from the colors within the identifiable video object.
6. The method of claim 2 , wherein the first key frame is a first predictive-coded frame (P-frame), and the second key frame is a second P-frame.
7. The method of claim 6 , wherein the first P-frame and the second P-frame each are encoded according to MPEG-4 encoding.
8. The method of claim 1 , further comprising storing an encoded video stream, containing the first key frame and the second key frame, on a tangible storage medium for distribution via a wide area network.
9. An apparatus comprising:
an encoder circuit configured for identifying an identifiable video object from a video picture of a digital video having video content and commercial content, the video picture contained within the video content;
the encoder circuit further configured for encoding the identifiable video object as a video overlay object;
the encoder circuit further configured for encoding the commercial content based on generating a first key frame containing the commercial content, and storing the video overlay object within the first key frame as an object that is not displayed as part of the commercial content; and
the encoder circuit further configured for encoding the video picture based on generating a second key frame that includes a default video object in place of the identifiable video object, the default video object including an overlay reference to the video overlay object within the first key frame, wherein the commercial content is protected based on an unavailability of the first key frame containing the video overlay object, during rendering of the second key frame, causing display of the default video object to visually corrupt the video picture;
the encoder circuit including a memory circuit configured for storing data associated with encoding any one of the identifiable video object, the commercial content, or the video picture.
10. The apparatus of claim 9 , wherein availability of the video overlay object, during rendering of the second key frame, causes the video picture to be displayed with the identifiable video object based on the overlay reference causing display of the video overlay object overlying the default video object.
11. The apparatus of claim 10 , wherein the encoder circuit is configured for inserting, during encoding of the video picture, an advertisement message associated with the commercial content as the default video object, the advertisement message displayed based on the unavailability of the video overlay object during rendering of the second key frame.
12. The apparatus of claim 10 , wherein the default video object contains uncoded data and no image data.
13. The apparatus of claim 10 , wherein the video overlay object includes first color information for rendering the identifiable video object according to respective colors within the identifiable video object, and the default video object includes second color information for rendering the identifiable video object according second colors substantially distinct from the colors within the identifiable video object.
14. The apparatus of claim 10 , wherein the first key frame is a first predictive-coded frame (P-frame), and the second key frame is a second P-frame.
15. The apparatus of claim 14 , wherein the first P-frame and the second P-frame each are encoded by the encoder circuit according to MPEG-4 encoding.
16. The apparatus of claim 9 , wherein the encoder circuit is configured for storing an encoded video stream, containing the first key frame and the second key frame, on a tangible storage medium for distribution via a wide area network.
17. An apparatus comprising:
means for reading a digital video having video content containing a video picture and commercial content; and
means for identifying an identifiable video object from the video picture, the means for identifying further configured for encoding the identifiable video object as a video overlay object;
the means for identifying further configured for encoding the commercial content based on generating a first key frame, and storing the video overlay object within the first key frame as an object that is not displayed as part of the commercial content;
the means for identifying further configured for encoding the video picture based on generating a second key frame that includes a default video object in place of the identifiable video object, the default video object including an overlay reference to the video overlay object within the first key frame, wherein unavailability of the video overlay object during rendering of the second key frame by a media player causes display of the default video object to visually corrupt the video picture.
