Abstract

A system for creating and viewing customized multimedia segments allows a user to create event identification data from in-band data in a program stream. The in-band data is processed and compiled into event identification data associated with the content stream. The event identification data identifies patterns or sequences of in-band data associated with events in the content stream. Metadata are also included in the event identification data. The event identification data is provided to multimedia devices which receive multimedia content streams containing content streams with in-band data. The in-band data are parsed and compared to the event identification data. If a match occurs, the multimedia device uses the metadata to identify events or perform specified actions.

Claims

1. A method comprising:

receiving, by a first media device, hash value sequence data from a second media device, the hash value sequence data corresponding to one or more locations within a multimedia content item;

generating, by the first media device, hash values based on the multimedia content item;

comparing the generated hash values to the hash value sequence data to locate the one or more locations within the multimedia content item;

displaying a graphical representation of the one or more locations on a graphical user interface.

2. The method of claim 1, wherein generating the hash values based on the multimedia content item includes generating the hash values from a portion of in-band data associated with the multimedia content item.

3. The method of claim 1, wherein the one or more locations within the multimedia content item correspond to locations selected by a user of the second media device.

4. The method of claim 1, wherein at least one location of the one or more locations is associated with metadata including content generated by a user of the second media device.

5. The method of claim 1, wherein at least one location of the one or more locations is associated with metadata including control and command information.

6. The method of claim 1, further comprising inserting one or more in-band tags into the multimedia content item, the one or more in-band tags corresponding to the one or more locations within the multimedia content item.

7. The method of claim 1, wherein displaying the graphical representation of the one or more locations on a graphical user interface includes displaying the graphical representations on a program cache bar.

8. The method of claim 1, wherein the hash value sequence data includes at least a particular hash value sequence, the particular hash value sequence associated with a time offset value representing a difference between a first time value associated with one hash value of the particular hash value sequence and a second time value associated with another hash value of the particular hash value sequence.

9. The method of claim 1, further comprising:

receiving a selection of a particular graphical representation of the one or more locations;

in response to receiving the selection of the particular graphical representation, skipping to the location within the multimedia content item associated with the particular graphical representation.

10. The method of claim 1, further comprising causing playback of segments of the multimedia content item, the segments defined by the one or more locations within the multimedia content item identified by the hash value sequence data.
