Latest Patents
One of his latest patents is a method and apparatus for determining a quantizing factor. This invention provides techniques for changing the quantization used in multiple generations of selected complexity of data quantization. The goal is to ensure that the errors incurred in subsequent generations are substantially the same as those in a generation with the same complexity of data. In a preferred embodiment, quantizing factors are selected from a preselected finite non-degenerative set of quantizing factors. These factors are provided in the form of arrays of a periodic series of individual quantizer values, maintaining a special numerical relationship between corresponding quantizer values in successive arrays. Another embodiment involves choosing an over-quantizing factor large enough to compress the data more than required in the first generation, ensuring sufficient compression in subsequent generations.
Another significant patent by Watney is a system and method to improve picture quality during the shuttling of video. This system enhances image quality during the shuttling of a video tape in a record and playback machine. It includes an offset signal source coupled to a displaceable mechanism during shuttling. This mechanism provides relative displacement between a reproduce transducer and a video tape, causing the transducer to cross tracks of recorded information irregularly. This approach allows for frequent updating of substantially all regions of an image field by information stored on the tape.
