Abstract

A method and system for identifying video segments for subsequent playback. Audio from an audio-visual presentation playing on a primary screen device is retrieved using a secondary screen device. At least one audio fingerprint is generated from the retrieved audio. The at least one audio fingerprint is sent to an audio fingerprint server. The audio fingerprint server obtains information identifying the audio-visual presentation and a relative time within the audio-visual presentation corresponding to the at least one audio fingerprint. The obtained information is used for subsequently retrieving the audio video presentation from a video content server.

Claims

1. A method for identifying video segments for subsequent playback comprising:

a) retrieving audio from an audio-visual presentation playing on a primary screen device using a secondary screen device;

b) generating at least one audio fingerprint from the retrieved audio;

c) sending the at least one audio fingerprint to an audio fingerprint server;

d) obtaining from the audio fingerprint server information identifying the audio-visual presentation and a relative time within the audio-visual presentation corresponding to the at least one audio fingerprint, said obtained information usable for subsequently retrieving said audio video presentation from a video content server.

2. The method defined by claim 1 further comprising:

a) generating a second relative time within the audio-visual presentation;

b) storing the second relative time for use during playback of the audio-visual presentation on at least one of the secondary screen device, the audio fingerprint server and a user account server.

3. The method defined by claim 1 further comprising storing the obtained audio fingerprint server information on at least one of the secondary screen device, the audio fingerprint server and a user account server.

4. The method defined by claim 1 further comprising sending information to the audio fingerprint server identifying a user of the secondary screen device.

5. The method defined by claim 1 further comprising:

a) obtaining a link to the obtained information;

b) sending the link to an audio-visual content server;

c) receiving from the audio-visual content server a video stream corresponding to the identified audio-visual presentation for playback.

6. The method defined by claim 1 further comprising adjusting the relative time to one of a predetermined earlier time and a predetermined later time.

7. The method defined by claim 6 wherein the predetermined earlier time is a start time of the audio-video presentation.

8. The method defined by claim 1 wherein said retrieving comprises one of recording a single sample of said audio and recording periodic samples of said audio.

9. The method defined by claim 1 wherein said generating comprises one of generating a single audio fingerprint from a single sample of said audio and generating a plurality of audio fingerprints from a plurality of samples of said audio.

10. The method defined by claim 1 further comprising using the obtained audio fingerprint server information to download to a playback device from an audio-visual content server the identified audio video presentation beginning at a predetermined time.

11. The method defined by claim 2 further comprising using the obtained audio fingerprint server information to download to a playback device from an audio-visual content server the identified audio video presentation beginning at a predetermined time and ending at the second relative time.

12. A method for identifying video segments in for subsequent playback comprising:

a) receiving an audio fingerprint from a secondary screen device;

b) comparing the received audio fingerprint with pre-existing audio fingerprints for a match;

c) upon determining said match, determining an identity of an audio-visual presentation corresponding to said match and a relative time within said audio-visual presentation corresponding to said match;

d) sending said identity and relative time to said secondary screen device.

13. The method defined by claim 12 further comprising:

a) receiving a second relative time within said audio-visual presentation from the secondary screen device;

b) storing the second relative time.

14. A system for identifying video segments for subsequent playback comprising:

a) an audio fingerprint server configured to;

1) receive at least one audio fingerprint from a secondary screen device;

2) compare the at least one received audio fingerprint with pre-existing audio fingerprints for a match;

3) upon determining said match, determine an identify of an audio-visual presentation corresponding, to said match and a relative time within said audio-visual presentation corresponding to said match;

4) send said identity and relative time to at least one of said secondary screen device and a predetermined address designated by a user of said secondary device;

b) an account database server accessible by said audio fingerprint server configured to store user information corresponding to the user of said secondary device.

15. The system defined by claim 14 wherein the audio fingerprint server is further configured to store said identity and relative time and user information for subsequent retrieval by said user for use in playing back at least a portion of said audio-visual presentation.

16. A method for identifying video segments for subsequent playback comprising:

a) sending a signal to a set top box which is tuned to a particular audio-visual presentation;

b) obtaining from the set top box information identifying the audio-visual presentation and a relative time within the audio-visual presentation corresponding to the time the signal was sent to the set top box, said obtained information usable for subsequently retrieving said audio video presentation from a video content server.
