1. A machine-implemented method, comprising:
- generating information about changes that are detected in video data that includes a series of frames;
aggregating the information to generate a plurality of video data change records, wherein each video data change record corresponds to a plurality of frames and includes change information that indicates changes that were detected in video data relative to the corresponding plurality of frames; and
storing said aggregated video data change records for subsequent forensic analysis.

Abstract
A method and apparatus for storing video data is provided. Video data, that comprises a series of frames, is received. Information about changes that are detected in the series of frames is generated. The information is aggregated to generate a plurality of video data change records. Each video data change record corresponds to a plurality of frames and includes change information that indicates changes that were detected relative to the corresponding plurality of frames. Events of interest that satisfy specified search criteria are searched for by comparing the specified search criteria against change information in one or more of the plurality of video data change records.

14. A machine-implemented method, comprising:
-
generating information about changes that are detected in video data that includes a series of frames; and
aggregating the information to generate a first plurality of video data change records, wherein each video data change record in the first plurality of change records corresponds to a plurality of frames and includes change information, aggregated at a relatively fine level of granularity, that indicates changes that were detected relative to the corresponding plurality of frames; and
aggregating the information to generate a second plurality of video data change records, wherein each video data change record in the second plurality of change records corresponds to a plurality of frames and includes change information, aggregated at a relatively coarse level of granularity, that indicates changes that were detected relative to the corresponding plurality of frames. - View Dependent Claims (15, 16, 30, 31, 32)
