    Abstract: A sub-sampling base intra predictive encoding system for a video compression and a method for providing higher compression efficiency are provided to increase compression efficiency by encoding the divided sub-screen image. An image dividing/coding order determiner(100) determines a coded order of the divided sub-screen image block. An intra predictor(121) produces a first prediction image block about the first image block. A differential image block coder produces the first subtractive color block corresponding to the pixel difference between the first image block and the generated first prediction image block. The generated first subtractive color block is encoded into the encoder. A differential image block decoder(124) decodes the encoded first subtractive color block.

    Abstract: An apparatus for audio encoding and decoding using warped linear prediction coding, and a method thereof are provided to remove the redundancy of an original signal by using the warped linear prediction coding in an audio encoding process, provide an error signal to an audio encoder as an input signal, and transform a psychological sound model to be suitable for the error signal, thereby increasing the efficiency of audio signal compression and performing audio signal encoding. An error signal calculating unit(110) performs the warped linear prediction coding of an audio signal inputted from the outside in a temporal area to calculate an error signal. A frequency domain converting unit(120) converts the error signal obtained in the error signal calculating unit into a frequency domain signal. A masking threshold value calculating unit(131,132) calculates a masking threshold value used in the encoding of the error signal by using an original signal and encoding information used in the warped linear prediction coding of the original signal. A perceptual encoding unit(140) performs the perceptual encoding of the error signal converted in the frequency domain converting unit by using the calculated masking threshold value.
