  • DPCM-based encoder, decoder, encoding method and decoding method
    Patent number: 8509553
    Abstract: An encoder, a decoder, an encoding method and a decoding method are provided. The encoder includes a reversible color transform module, a difference pulse code modulation (DPCM) intra prediction module, a quantization module, a reversible frequency transform module and an entropy coding module. The reversible color transform module performs a reversible color transform to output a transformed video signal according to an input video signal. The DPCM intra prediction module performs a DPCM intra prediction to output a least residual according to the transformed video signal. The quantization module performs a quantization operation to output a quantization coefficient according to the least residual. The reversible frequency transform module performs a reversible frequency transform to output a frequency coefficient according to the quantization coefficient. The entropy coding module performs entropy coding to output a compression bit stream according to the frequency coefficient.
