We propose an MPEG-2 to H.264 intra transcoding for interlace stream of frame and field macroblock intermingled to improve our previous work. This method uses an adaptive MB pair type selection method that keeps as many discrete cosine transform (DCT) coefficients of the original MPEG-2 bitstream as possible to avoid mixture of re-quantization noise. Experimental results show that the proposed method improves the peak signal-to-noise ratio (PSNR) values by about 0.33-1.55dB over those of the conventional methods.
