METHOD FOR VIDEO DATA RANKING
First Claim
1. This video data ranking method involves the receipt of video data from at least from one video camera or sensor and transmission of ranked video data via communication links to at least one user and/or storage. It is characterized as follows:
- received live video data is first segmented based on at least one object and/or event;
then, each segment is analyzed for characteristics that are critical for the segment'"'"'s priority and/or used for searching segments in the storage;
then, each segment is prioritized based on its characteristics;
then, segments are ranked according to their estimated priorities; and
the resulting priority queue of segments or one highest-priority segment is transmitted via communication links to at least one user and/or storage.

Abstract
This Invention deals with data processing methods. This method involves the receipt of video data from a video camera and transmission of ranked video data to a user and/or to storage via communication links. Received live video data is first segmented based on at least one object and/or event; then, each segment is analyzed for characteristics that are critical for the priority estimate of a segment and/or used to search for segments in the storage. Each segment is prioritized based on its characteristics. Segments are ranked based on their priority estimates; the resulting priority queue of segments or one segment of the highest priority is transmitted to a user and/or recorded into storage. This Invention reduces load imposed on limited bandwidth communication links and improves video data processing without sacrificing video quality.
