  • IMAGE ENCODER AND DECODER USING UNIDIRECTIONAL PREDICTION
    Publication number: 20240107032
    Abstract: The present invention relates to an image encoding and decoding technique, and more particularly, to an image encoder and decoder using unidirectional prediction. The image encoder includes a dividing unit to divide a macro block into a plurality of sub-blocks, a unidirectional application determining unit to determine whether an identical prediction mode is applied to each of the plurality of sub-blocks, and a prediction mode determining unit to determine a prediction mode with respect to each of the plurality of sub-blocks based on a determined result of the unidirectional application determining unit.

  • Semiconductor device
    Patent number: 10090058
    Abstract: A semiconductor device may be provided. The semiconductor device may be configured for detecting a defect of a fuse set. The semiconductor device may include a pseudo initial signal generator configured to generate pseudo initial information on the basis of a test mode signal. The semiconductor device may include a fuse-set defect detector configured to compare fuse-set information of a fuse set or the pseudo initial information with a reference value on the basis of a fuse-set address, and detect a defect of the fuse set.

  • Data storage device, user device and data write method
    Patent number: 9563549
    Abstract: Disclosed is an address mapping method for a data storage device using a hybrid mapping scheme. The address mapping method determines whether write data includes a defined super sequential block (SSB), and selects an address mapping mode for the write data in accordance with whether or not a SSB is present.

  • LCD driving circuit
    Publication number: 20020089498
    Abstract: LCD driving circuit for applying a signal of a first polarity and a signal of a second polarity opposite to the first polarity to an LCD alternately, including first and second data latches for latching source data in succession, a DAC for converting a latch data into an analog signal to provide a signal of the first polarity, a driving signal processing block for receiving a converted signal from the DAC to provide a signal of the second polarity, a multiplexer for selecting either one of signals of first and second polarities in response to a polar signal, and a buffer for buffering a signal from the multiplexer and applying a source driving signal to LCD cells, thereby permitting to use only one type of DAC.
