    摘要: A deblocking filter used in a video encoder/decoder based on a multilayer is disclosed. The deblocking filtering method includes choosing a present block and its neighboring block on which a deblocking filtering will be performed, judging whether the present block and the neighboring block have been coded by the intra BL mode, choosing a deblocking filter strength according to the result of the judgment, and performing the deblocking filtering with respect to a boundary between the present block and the neighboring block and according to the deblocking filter strength.

    摘要: A method and apparatus of improving the compression efficiency of a motion vector by efficiently predicting a motion vector in an enhancement layer from a motion vector in a base layer in a video coding method using a multi-layer are provided. The method includes obtaining a motion vector in a base layer frame having a first frame rate from an input frame, obtaining a motion vector in a first enhancement layer frame having a second frame rate from the input frame, the second frame rate being greater than the first frame rate, generating a predicted motion vector by referring to a motion vector for at least one frame among base layer frames present immediately before and after the same temporal position as the first enhancement layer frame if there is no base layer frame at the same temporal position as the first enhancement layer frame, and coding a difference between the motion vector in the first enhancement layer frame and the generated predicted motion vector, and the obtained motion vector in the base layer.

    摘要: A bit line sense amplifier is provided. The bit line sense amplifier includes a first sense amplifier block in which a plurality of first sense amplifiers for sensing and amplifying data of a bit line or a complementary bit line are laid out, and first drivers, which are arranged outside the plurality of first sense amplifiers, for pulling down the bit line or the complementary bit line to a first voltage level. The bit line sense amplifier further includes a second sense amplifier block with a plurality of second sense amplifiers and second drivers for pulling up the bit line or the complementary bit line to a second voltage level. By arranging the drivers outside the bit sense amplifiers, effects caused by variation in critical dimensions (CDs) of gates are minimized and the entire area of the bit line sense amplifier is reduced.
