Latest Patents

One of his latest patents is focused on the detection of repeated and frozen frames in a video signal. This invention involves an apparatus and method that obtains the absolute differences between pixels in corresponding fields of consecutive frames. It generates a logic bit-map based on a threshold related to the maximum absolute difference for the field. The logic "1"s in the logic bit-map are counted to determine a normalized distribution count for the field. The actual counts are then compared with bounds generated from the normalized distribution count to report a repeated frame. In the absence of noise, the actual counts are compared with a minimum value to achieve the same result.

Another notable patent by Kamalesh U Patel is an in-service, realtime picture quality analysis method. This method determines the degradation of a test video signal at a test point with respect to a reference video signal. It generates a set of parameters from the reference video signal that characterize the images represented. These parameters are inserted into a transport stream along with an encoded version of the reference video signal. At the test point, the parameters are extracted, and the test video signal is decoded. A corresponding set of parameters is generated for the test video signal, and both sets are compared to produce a picture quality rating that represents the degradation of the test video signal.
