METHOD AND APPARATUS FOR DETECTING AN INSERTED SEGMENT INTO A VIDEO DATA STREAM
First Claim
1. A method for detecting an inserted segment of a video data stream in which a graphical object is not present, the method comprising the steps of:
- detecting presence of at least one active graphical object in a video data stream;
concurrently detecting appearance of a new graphical object in said video data stream;
determining the most reliable graphical object from said at least one active graphical object and said new graphical object;
detecting presence of said most reliable graphical object from a point in said video data stream at which said new graphical object is detected; and
detecting an inserted segment of said video data stream if no graphical object is detected.

Abstract
An inserted segment of a video data stream is detected if no graphical object is detected. The presence of at least one active graphical object in the video data stream is detected concurrently with detecting appearance of a new graphical object in the video data stream. The most reliable graphical object from the at least one active graphical object and the new graphical object is determined and the presence of the most reliable graphical object is detected from a point in the video data stream at the new graphical object was detected to appear. An inserted segment of the video data stream is detected if no graphical object is detected.

11. Apparatus for detecting an inserted segment of a video data stream in which a graphical object is not present, the apparatus comprising:
-
a graphical object presence detector for detecting presence of at least one active graphical object; a graphical object detector in parallel to said graphical object presence detector for detecting appearance of a new graphical object; and a controller for determining the most reliable graphical object from said at least one active graphical and said new graphical object, wherein said graphical object presence detector detects presence of said most reliable graphical object from a point in said video data stream at which said new graphical object is detected and for detecting an inserted segment of said video data stream if no graphical object is detected. - View Dependent Claims (12)
