摘要： A video decoder for high definition television includes a variable length decoder decoding codes corresponding to discrete cosine transform (DCT) coefficients of an applied video bit stream, and produces a run-level pair for each code. An index decoder stores run-level pairs produced from the variable length decoder, and produces the position information indicating the number of a level value of a corresponding run-level pair among 64 DCT coefficients. An inverse quantizer obtains an added value corresponding to the position information of the index decoder from a quantization matrix, and performs an inverse quantization by multiplying a quantizer level for determining a quantization step and DCT coefficient to the added value. An inverse scanner includes a plurality of memories, and inversely scanning the DCT coefficient inversely quantized and applied serially from the inverse quantizer and produces the DCT coefficient in parallel at the same time. An inverse discrete cosine transformer performs an inverse DCT (IDCT) of the DCT coefficient produced in parallel from the inverse scanner.

摘要： The motion vector decoder includes a parameter delay block which delays transmissions of various input signals necessary for motion vector decoding; a motion vector residual block which extracts a motion residual value and outputs a positive number of the motion residual value; a motion vector code table block which searches for a motion code, a condition of a sign of the motion code, and a zero condition of the motion code using a variable length decoding table and outputting the searched values; a motion vector delta block which calculates a difference of motion vectors from the motion vector residual block and the motion vector code table block; a MV adder which adds the difference value received from the motion vector delta block and a motion vector of a preceding macroblock to output a new motion vector; and a register which updates a flip-flop corresponding to a current (r, s, t) of a new motion vector. The circuit blocks each have at least one flip-flop to allow processing of each block within a single clock.
