Latest Patents
One of his latest patents is the "Tab coefficient updating device of finite impulse-responding adaptive." This device is designed to greatly reduce the amount of hardware required while integrating its tab coefficient updating value operating circuit using a simple circuit design. The device includes a finite impulse-responding adaptive digital filter unit that filters an input signal using a tab coefficient updated for a predetermined tab. It also features a tab address generating unit that produces a tab address signal associated with the predetermined tab, which is applied to both the updating value operating unit and the digital filter unit.
Another notable patent is the "Variable length decoding of motion vectors." This invention involves a motion vector decoding apparatus and method that converts a variable length motion vector into its original form using a difference component of the motion vector. The apparatus comprises an X-axis motion vector component decoder and a Y-axis motion vector component decoder, both of which decode their respective components in response to motion vector difference components. This innovation allows for the rapid and accurate restoration of compressed video signals in a variable length decoder.
