Latest Patents
One of his latest patents is titled "Compressed Audio Silencing." This invention presents a method and apparatus for suppressing spurious audio frequency sounds in systems where audio frequency sounds are significantly raised in frequency and formatted to a video line signal. The invention incorporates a sufficient number of guard samples at the beginning of each line of audio to ensure the amplitude response reaches the specified value before the relevant samples occur. This method allows for satisfactory functioning with equipment that has a limited frequency response range, making it more cost-effective to manufacture and use.
Another significant patent by John A Roe is "Adaptive Automatic Gain Control." This invention optimally processes television compressed audio signals by adaptively controlling the gain of the apparatus. It compares the average value of the digitized signal to a reference value to produce a gain control signal, accommodating variable input video signal amplitudes to a fixed analog to digital converter range.
