Claims

1. A method comprising:

scheduling a recording of a particular media content in a content stream at a scheduled start time;

receiving content in the content stream prior to the scheduled start time;

deriving a first fingerprint from the content and querying a fingerprint database to identify the content in the content stream as the particular media content;

starting the recording of the particular media content in the content stream prior to the scheduled start time;

monitoring the content stream for identifying a second media content in the content stream that is different than the particular media content by;

deriving a second fingerprint from the second media content;

querying the fingerprint database with the second fingerprint to determine that the second media content in the content stream is different than the particular media content;

stopping the recording of the content stream in response to identifying that the second media content in the content stream is different than the particular media content;

wherein the method is performed by one or more computing devices.

2. The method as recited in claim 1, wherein the scheduled start time is based on information associated with an electronic programming guide (EPG).

3. A method comprising:

recording a content stream comprising a first media content;

monitoring the content stream for identifying a second media content that is different than the first media content the first media content and the second media content being program content;

identifying the second media content in the content stream that is different than the first media content by;

deriving a fingerprint from the second media content;

querying a fingerprint database with the fingerprint to determine that the second media content in the content stream is different than the first media content;

stopping the recording of the content stream in response to identifying that the second media content in the content stream is different than the first media content;

wherein the method is performed by one or more computing devices.

4. The method as recited in claim 3, wherein the recording is stopped at an actual end time of the first media content that is different than a scheduled end time of the first media content indicated in an electronic programming guide (EPG).

5. The method as recited in claim 3, wherein an electronic programming guide indicates that the second media content is available on the content stream subsequent to the first media content.

6. The method as recited in claim 3, further comprising:

detecting that the second media content is available on the content stream later than a scheduled start time for the second media content;

modifying a scheduled recording time interval for the second media content in response to the detecting step.

7. A non-transitory computer readable medium storing a set of instructions, which when executed by a processor, perform steps comprising:
