Patent ID: 8564669

Claim:
A method of analyzing a video stream using a video analyzer, the video stream comprising image frame data corresponding to an integer N number of image frames, respectively, the video analyzer comprising a controller and a frame processor, said method comprising: setting, by way of the controller, a problem threshold value corresponding to a parameter of the image frame data, wherein said setting a problem threshold value corresponding to a parameter of the image frame data comprises setting an interrupted threshold value; receiving, by way of the frame processor, first image frame data corresponding to a first image frame; analyzing, by way of the frame processor, the parameter of a portion of the received first image frame data and generating an analyzed value; determining that there is a problem when the analyzed value is less than the interrupted threshold value; and generating, via the controller, an indication of a black or snowy image when the problem is determined, wherein the portion of the analyzed portion of the received first image frame data is less than the total received first image frame data.
