Abstract

A method and apparatus for recognizing and synchronizing to in-band data at a multimedia device is provided. A content stream includes in-band data. The in-band data is processed and in-band data pattern data associated with the content stream are created. Metadata are attached to the event identification data. The event identification data are provided to multimedia devices which receive broadcasted multimedia content streams containing video programs with in-band data. The in-band data are processed and compared to the event identification data. If a match occurs, the multimedia device uses the metadata to perform specified actions.

Claims

1. A method for processing in-band data, comprising:

receiving a multimedia content stream at a first multimedia device, wherein the multimedia content stream contains in-band data;

processing the in-band data by the multimedia device, wherein processing the in-band data comprises computing a hash value sequence associated with a location in the multimedia content stream;

determining that the hash value sequence matches a particular pattern associated with one or more events;

inserting one or more in-band tags at the location in the multimedia content stream.

2. The method as recited in claim 1, further comprising:

subsequent to inserting the one or more in-band tags at the location in the multimedia content stream, storing the multimedia content stream for later playback by the multimedia device.

3. The method as recited in claim 1, wherein inserting the one or more in-band tags at the location comprises interleaving data objects into the multimedia content stream.

4. The method as recited in claim 1, further comprising:

playing the multimedia content stream subsequent to inserting the one or more in-band tags at the location in the multimedia content stream;
