SYSTEM AND METHODS FOR DETERMINING THE DESIRABILITY OF VIDEO PROGRAMMING EVENTS

摘要

The desirability of programming events may be determined by analysing metadata (20) for individual programming events using viewer preferences represented in viewer profiles. Metadata (20) may include scores associated with categories of hierarchy, and viewer profiles may include preference scores associated with categories of classification hierarchy. Metadata (20) may further include keywords or descriptive data, and viewer profiles may also include keywords. Keywords in viewer profiles may be associated with individual classification hierarchy. Analysis of the programming events may be performed to determine a recording schedule or an alert schedule. The programming events (28) for which metadata (20) is provided may be an individual segments of a video program. In addition, timing data may be provided in a closed caption data stream to identify beginnings of programming events, and may be used by recording devices to control recording or playback.
