Abstract

Techniques for annotating or bookmarking digital information. The digital information is annotated based upon events determined from the digital information. The digital information that is annotated may comprise one or more types of information including but not restricted to video information, audio information, images, documents, slides information, whiteboard information, notes information, and the like.

Claims

1. A method performed by a computer system of annotating digital information, the method comprising:

identifying a set of one or more events from the digital information;

outputting, via an output device, information identifying the set of events;

receiving user input indicating selection of at least one event from the set of events; and

annotating the digital information based upon the at least one event.

2. The method of claim 1 wherein annotating the digital information comprises:

determining a time associated with the at least one event; and

annotating the digital information based upon the time associated with the at least one event.

3. The method of claim 1 wherein annotating the digital information comprises:

annotating the digital information for a duration of the at least one event.

4. The method of claim 1 further comprising determining a visual representation for each event in the set of events, and wherein outputting the information identifying the set of events comprises outputting the visual representation for each event in the set of events.

5. The method of claim 1 wherein:

the digital information is captured during a recording session; and

the identifying the set of events, outputting information identifying the set of events, receiving the user input, and annotating the digital information are performed during the recording session.

6. The method of claim 1 wherein:

the digital information comprises audio information and video information; and

identifying the set of one or more events comprises analyzing the audio information and the video information to identify the set of events.

7. A method performed by a computer system of annotating digital information, the method comprising:

identifying a set of one or more events from the digital information;

receiving a signal;

determining a first event for the signal from the set of events; and

annotating the digital information based upon the first event.

8. The method of claim 7 wherein the signal is caused due to an action performed by a user.

9. The method of claim 7 wherein the digital information is captured during a recording session and wherein the signal is caused by an action performed by a user during the recording session.

10. The method of claim 7 wherein determining the first event from the set of events for the signal comprises:

determining a time associated with the signal; and

determining an event from the set of events whose start time is prior to and closest to the time associated with the signal.

11. The method of claim 7 wherein annotating the digital information comprises:

determining a time associated with the first event; and

annotating the digital information based upon the time associated with the first event.

12. The method of claim 7 wherein annotating the digital information comprises:

annotating the digital information for a duration of the first event.

13. The method of claim 7 wherein:

the digital information is captured during a recording session; and

the identifying the set of events, receiving the signal, determining the first event, and annotating the digital information are performed during the recording session.

14. A system for annotating digital information, the system comprising:

a memory storing the digital information;

an output device; and

a processor couple to the memory, the processor configured to;

identify a set of one or more events from the digital information;

cause the output device to output information identifying the set of events;

receive user input indicating selection of at least one event from the set of events; and

annotating the digital information based upon the at least one event.

15. The system of claim 14 wherein the processor is configured to:

determine a time associated with the at least one event; and

annotate the digital information based upon the time associated with the at least one event.

16. The system of claim 14 wherein the processor is configured to annotate the digital information for a duration of the at least one event.

17. The system of claim 14 comprising:

a set of one or more capture devices configured to capture the digital information during a recording session; and

wherein the processor is to configured to identify the set of one or more events, cause the output device to output the information identifying the set of events, receive user input, and annotate the digital information during the recording session.

18. A system for annotating digital information, the system comprising:

a memory storing the digital information; and

a processor couple to the memory, the processor configured to;

identify a set of one or more events from the digital information;

receive a signal;

determine a first event for the signal from the set of events; and

annotate the digital information based upon the first event.

19. The system of claim 18 wherein the signal is caused due to an action performed by a user.

20. The system of claim 18 wherein the digital information is captured during a recording session and wherein the signal is caused by an action performed by a user during the recording session.

21. The system of claim 18 wherein the processor is configured to:

determine a time associated with the signal; and

determine an event from the set of events whose start time is prior to and closest to the time associated with the signal.

22. The system of claim 18 wherein the processor is configure to:

determine a time associated with the first event; and

annotate the digital information based upon the time associated with the first event.

23. The system of claim 18 wherein the processor is configured to annotate the digital information for a duration of the first event.

24. The system of claim 18 comprising:

a set of one or more capture devices configured to capture the digital information during a recording session; and

wherein the processor is configured to identify the set of events, receive the signal, determine the first event, and annotate the digital information during the recording session.

25. A computer-readable medium storing a plurality of instructions for controlling a data processor to annotate digital information, the plurality of instructions comprising:

instructions that cause the data processor to identify a set of one or more events from the digital information;

instructions that cause the data processor to output, via an output device, information identifying the set of events;
