Study on a method for detecting failure of digital television transmission based on extraction of feature information of embedded invisible marker signals and statistical test

摘要

The authors study about a method for detecting television transmission failure by use of invisible markers signals. The proposed system is based on extraction of feature information of detected invisible markers and statistical test. The proposed method defines the transition of marker detection result between adjacent frames as feature information and conducts statistical hypothesis test to detect local impairment in a frame. Computer simulations show that the proposed method achieved better performance than the conventional method.
