  • Computationally fast and efficient DV to DVD transcoding
    Publication number: 20030194008
    Abstract: A method is described for quickly and efficiently transcoding digital video (DV) data to digital versatile disk (DVD) data. The method uses the baseline method for DV to DVD transcoding (i.e., full DV decoding, and DVD encoding), but eliminates the DCT and IDCT functions from the baseline method for I (Intraframe) coded frames; and further combines the inverse quantization (IQ) and inverse discrete cosine transformation (IDCT) functions of DV decoding, and the quantization (Q) and discrete cosine transformation (DCT) functions of DVD encoding into a single quantization function for I/P (Intraframe/Predictive) coded frames and P/P (Predictive/Predictive) coded frames.
