Title: Rashid Ansari: Innovator in Video Processing Technologies
Introduction
Rashid Ansari is a notable inventor based in Hillsborough, NJ (US), recognized for his contributions to video processing technologies. With a total of two patents to his name, he has made significant advancements in the field of video coding and signal processing.
Latest Patents
Rashid Ansari's latest patents include a method and circuit for adjusting the size of a video frame. This invention controls the number of bits used to code a frame of video by managing the frame size. In the preprocessing stage of a video coding circuit, each frame is processed by a low pass anti-aliasing filter in both horizontal and vertical directions. The cutoff frequencies are determined by a desired frame reduction factor, allowing for a reduction in the sampling rate. This innovative approach results in a linear decrease in the number of code bits as the sampling rate is reduced.
Another significant patent is related to HDTV sub-band coding using an IIR filter bank. This technique involves the sub-band decomposition and reconstruction of video signals. Each field of a video signal is decomposed into sub-bands utilizing a polyphase filter bank unit, which includes an infinite impulse response allpass filter. This method eliminates the need for a full field memory in the reconstruction process, showcasing Ansari's innovative approach to video signal processing.
