摘要： A predictive coding method for coding intra of frames is revealed. Firstly, an encoder divides an image frame into a plurality of macroblocks. Then the encoder sets predictive coding models corresponding to these macroblocks according to a ratio. The encoder performs predictive coding for coding each macroblock according to the corresponding predictive coding model so as to get and output a coded image. By the present invention, various predictive coding models are set and applied to code the different macroblocks so as to increase predictive coding efficiency. The intra prediction efficiency and image compression efficiency are improved simultaneously.

摘要： The present invention provides a device and method for applying 1-D and 2-D DCT and IDCT transforms to sets of input data, typically 8×8 or 16×16 matricies of coefficients. In one embodiment, the present invention provides input lines, logic to pre-add input values and generate operands and one or more adder networks that effectively carry out the multiplication operations required to apply a DCT/IDCT transform. The device may apply a 1-D transform twice to accomplish a 2-D transform. Alternatively, the present invention may either include successive stages of logic for the second 1-D transform or it may send data transformed once back through the same logic to pre-add and adder networks for the second 1-D transform. Calculations may be carried out after Booth encoding of operands. The processing may be split between producing vp, a vector of sums of output values, and producing vn, a vector of differences of output values, which vectors may be recombined to produce an output vector v.
