Abstract :
We have developed a real-time encoder chipset which completely complies to the standard ISO/IEC13818-2|ITU-TH.262 (also known as “MPEG2 Video”), for the Main Profile at Main/High Level. This set consists of the following five chips: the “PRE” (Pre-processing) chip, the “CME” (Coarse Motion Estimation) chip, the “COD” (Predictive Coding) chip, the “QVL” (Orthogonal Transformation, Quantization, and Variable Length Coding) chip, and the “FME” (Fine Motion Estimation) chip. One set of these five chips is sufficient for real-time encoding of source images equivalent to the ITU-RBT.601 standard, and by connecting eight sets together, HDTV level real-time encoding is possible
