Abstract

Various embodiments provide an electronic device that includes video storage memory, a video signal receiver, and a video storage controller. The video signal receiver is configured to receive a video stream containing advertising content and program/movie content from a broadcast source. The video storage controller is configured to identify locations of advertising content interspersed among program/movie content in the received video stream, and to record addressable chapter marks for the identified locations of the advertising content and a video stream that is based on the received video stream into the memory. The addressable chapter marks may be displayed on a display and used by a viewer to jump playback of the video stream between the chapter marks.

Claims

1. An electronic device comprising:

video storage memory;

a video signal receiver that is configured to receive from a broadcast source a video stream containing advertising content and program/movie content; and

a video storage controller that is configured to identify locations of advertising content interspersed among program/movie content in the received video stream, and to record addressable chapter marks for the identified locations of the advertising content and a video stream that is based on the received video stream into the memory.

2. The electronic device of claim 1, wherein the video storage controller is further configured to insert the addressable chapter marks within an address look-up table that is recorded within a same memory file that contains the video stream.

3. The electronic device of claim 1, wherein the video storage controller is further configured to remove and replace each instance of the advertising content of the received video stream with a corresponding one of the addressable chapter marks to generate a modified video stream that is recorded into the memory.

4. The electronic device of claim 1, wherein the video storage controller is further configured to extract subtitle text that is embedded in the program/movie content portion of the received video stream and located within a defined play time relative to each of the identified locations of advertising content, and to insert the extracted subtitle text as part of the addressable chapter marks that are recorded with the video stream into the memory.

5. The electronic device of claim 4, wherein the video storage controller is further configured to begin displaying on a display the extracted subtitle text for a next occurring addressable chapter mark during playback of the video stream before the playback reaches that next occurring addressable chapter mark.

6. The electronic device of claim 1, wherein the video storage controller is further configured to capture a snapshot of a video frame of the program/movie content portion of the video stream following each of the identified locations of the advertising content, and to insert the captured snapshots as part of the addressable chapter marks that are recorded with the video stream into the memory.

7. The electronic device of claim 6, wherein the video storage controller is further configured to begin displaying on a display the captured snapshot for a next occurring addressable chapter mark during playback of the video stream before the playback reaches that next occurring addressable chapter mark.

8. The electronic device of claim 1, wherein the video storage controller is further configured to playback the video stream, which was recorded into the memory, onto a video display, to display on the display a playback timeline that indicates a playback length of the video stream and includes an indicia that indicates a present playback location within the playback timeline, and to display on the playback timeline at least a plurality of the addressable chapter marks having spacing therebetween that is proportional to their relative locations within the playback timeline of the video stream.

9. The electronic device of claim 8, wherein the video storage controller is further configured to respond to a viewer chapter selection signal by jumping a playback location within the video stream to locations defined by selected ones of the addressable chapter marks.

10. The electronic device of claim 9, wherein the video storage controller is further configured to respond to each occurrence of the viewer chapter selection signal by jumping the playback location to a different one of sequentially occurring time locations in the video stream defined by sequential ordered ones of the addressable chapter marks.

11. The electronic device of claim 9, wherein the video storage controller is further configured to extract subtitle text that is embedded in the program/movie content portion of the video stream recorded in the memory and located within a defined play time relative to a next playback occurring one of the displayed addressable chapter marks, and to begin displaying the extracted subtitle text before playback reaches that next occurring displayed addressable chapter mark.

12. The electronic device of claim 11, wherein the subtitle text comprises closed captioned text that is embedded in the program/movie content portion of the video stream recorded in the memory, and the video storage controller is further configured to extract and display on the video display a defined number of words of the closed captioned text that occur prior to the next playback occurring one of the displayed addressable chapter marks.

13. The electronic device of claim 9, wherein the video storage controller is further configured to extract subtitle text that is embedded in the program/movie content portion of the video stream recorded in the memory and located within a defined play time relative to a plurality of the displayed addressable chapter marks, and to display on the display the extracted subtitle text for the plurality of the displayed addressable chapter marks.

14. The electronic device of claim 13, wherein the video storage controller is further configured to display the extracted subtitle text associated with a plurality of the displayed addressable chapter marks ordered on the display adjacent to those displayed addressable chapter marks.

15. The electronic device of claim 13, wherein the extracted subtitle text comprises closed captioned text that is embedded in the video stream recorded in the memory, and the video storage controller is further configured to extract and display on the video display a defined number of words of the closed captioned text that occur following a plurality of the displayed addressable chapter marks.

16. The electronic device of claim 9, wherein the video storage controller is further configured to capture a snapshot of a video frame of the program/movie content portion of the video stream following a next playback occurring one of the displayed addressable chapter marks, and to begin displaying the captured snapshot before playback reaches that next occurring displayed addressable chapter mark.

17. The electronic device of claim 9, wherein the video storage controller is further configured to capture a snapshot of a video frame of the program/movie content portion of the video stream following each of the displayed addressable chapter marks, and to display on the video display the captured snapshots for the plurality of the displayed addressable chapter marks.

18. The electronic device of claim 1, wherein the video storage controller is further configured to identify the location of each instance of the advertising content in the received video stream in response a threshold amount of change of scene content occurring between two sequential frames of the video stream during a time window defined around an expected time of occurrence of each instance of the advertising content.

19. The electronic device of claim 18, wherein the video storage controller is further configured to identifying the location of a first instance of the advertising content and to then determine a start location of a subsequent time window, which it will use to search for a second instance of the advertising content, as a defined time interval away from the identified location of the first instance of the advertising content.

20. The electronic device of claim 1, wherein the video storage controller is further configured to generate a message including an identifier for the video stream and the associated addressable chapter marks, and to transmit the message through an external network to another electronic device for use in displaying the video stream with the addressable chapter marks.
