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 captured during a recording session, the method comprising:

identifying, by the computer system, a set of one or more events from the digital information, the identifying based upon analysis of the digital information performed by the computer system;

determining, by the computer system, a representation for each event in the set of one or more events;

outputting, by the computer system, via an output device, the representation for each event in the set of one or more events;

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

in response to the user input indicating selection, annotating, by the computer system, the digital information based upon the at least one event,

wherein the identifying, determining, outputting, receiving, and annotating are performed during the recording session.

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

determining, by the computer system, 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 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.

5. The method of claim 1 wherein:

the digital information comprises audio information; and

the set of events comprises at least one from an event indicating a new audio, an event indicating a particular audio source, an event indicating a period of silence of at least a preconfigured length, or an event indicating a change in direction of an audio source.

6. The method of claim 1 wherein the set of events comprises at least one event from an event indicating a change from one slide to another slide, an event indicating elapsing of a preconfigured time period without a change in slide, or an event indicating an absence of a slide-related event for a period of time.

7. The method of claim 1 wherein the set of events includes at least one event based upon audio information, video information, or slide related information included in the digital information.

8. The method of claim 1 wherein the representation is a visual representation.

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

capturing during a recording session, by the computer system, the digital information;

identifying, by the computer system, a set of events from the digital information, the identifying based upon analysis of the digital information performed by the computer system;

receiving, by the computer system, a signal;

determining, by the computer system, a first event from the set of events from the digital information, based on the signal; and

in response to determining the first event based on the signal, annotating, by the computer system, the digital information based upon the first event,

wherein the identifying, receiving, determining, and annotating are performed during the recording session.

10. The method of claim 9 wherein the signal is caused due to an action performed by a user.

11. The method of claim 9 wherein determining the first event 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.

12. The method of claim 9 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.

13. The method of claim 9 wherein annotating the digital information comprises:

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

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

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

a memory storing the digital information;

an output device; and

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

identify a set of events from the digital information, the identifying based upon analysis of the digital information performed by the system;

determine a representation for each event from the set of events;

cause the output device to output the representation for each event from the set of events;

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

in response to the user input indicating selection, annotate the digital information based upon the at least one event,

wherein the processor is configured to identify, determine, cause the output device to output, receive, and annotate during the recording session.

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

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

a memory storing the digital information; and

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

identify a set of events from the digital information, the identifying based upon analysis of the digital information performed by the system;

after identifying the set of events, receive a signal;

determine a first event from the set of events, based on the signal; and

in response to determining the first event based on the signal, annotate the digital information based upon the first event,

wherein the processor is configured to identify, receive, determine, and annotate during the recording session.

18. The system of claim 17 wherein the signal is caused due to an action performed by a user.

19. The system of claim 17 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.

20. The system of claim 17 wherein the processor is configured to:
