SYSTEM AND METHOD FOR ANALYZING VIDEO STREAM
First Claim
1. 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;
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 whether there is a problem based on the analyzed value and the problem threshold value; and
generating, via the controller, a problem indication when a 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.

Abstract
A method is disclosed of analyzing a video stream using a video analyzer. The video stream includes image frame data corresponding to an integer N number of image frames, respectively. The video analyzer includes a controller and a frame processor. The method includes setting a problem threshold value corresponding to a parameter of the image frame data, receiving first image frame data corresponding to a first image frame, analyzing the parameter of a portion of the received first image frame data and generating an analyzed value and determining whether there is a problem based on the analyzed value and the problem threshold value. The portion of the analyzed portion of the received first image frame data is less than the total received first image frame data.

15. A video analyzer for use with image frame data, which corresponds to an integer N number of image frames, respectively, said video analyzer comprising:
-
a frame processor operable to process a portion of image frame data corresponding to a portion of one of the integer N number of image frames and to output an image frame data output signal; a comparator operable to compare the image frame data output signal with a predetermined threshold and to output a compared signal; and a controller operable to output a first indicator signal based on the compared signal, wherein the portion of the one of the integer N number of image frames is less than the entire one of the integer N number of image frames, wherein the first indicator signal corresponds to a problem in the image frame data when the compared signal corresponds to the image frame data output signal being less than the predetermined threshold, and wherein the first indicator signal corresponds to no problem in the image frame data when the compared signal corresponds to the image frame data output signal being more than the predetermined threshold. - View Dependent Claims (16, 17, 18, 19)

20. A video analyzer for use with image frame data, which corresponds to an integer N number of image frames, respectively, said video analyzer comprising:
-
a frame processor operable to process a portion of image frame data corresponding to a portion of one of the integer N number of image frames and to output an image frame data output signal; a moving-average processor operable to process a moving-average of image frame data of up to an integer M number corresponding to up to integer M number of image frames, respectively, and to output a moving-average output signal; a comparator operable to compare the moving-average output signal with a predetermined threshold and to output a compared signal; and a controller operable to output an indicator signal based on the compared signal, wherein the portion of the one of the integer N number of image frames is less than the entire one of the integer N number of image frames, wherein the indicator signal corresponds to a problem in the image frame data when the compared signal corresponds to the moving-average data output signal being less than the predetermined threshold, and wherein the indicator signal corresponds to no problem in the image frame data when the compared signal corresponds to the moving-average data output signal being more than the predetermined threshold.
