Latest Patents

Among his latest patents, Smith has developed a "Method for Generating a Compressed Video Signal." This invention includes an apparatus designed to encode an image signal, featuring an acquisition module that receives the image signal. A first processor is coupled to this module, while at least one encoder processor is linked to the first processor. The encoder processor produces an encoded image signal under the control of the first processor. The method involves converting an input image signal into a predetermined digital format and transferring this digital format to the encoder processor. Additionally, a hierarchical vector quantization compression algorithm is applied to the digitized image signal, resulting in a collected encoded bit stream. This method and apparatus can be utilized with an ordinary modem to transmit or receive audio, video sequences, or still images.

Another significant patent is the "Method for Adjusting the Quality of a Video Coder." Similar to his previous invention, this method and apparatus also focus on encoding an image signal with an acquisition module, a first processor, and at least one encoder processor. The steps involved mirror those of his earlier patent, emphasizing the conversion of an
