Abstract: MPEG-2 ML@4:2:2P Compression with I-frames only and a datarate of 50 Mbit/s has been recently proposed by EBU and SMPTE as one of two compression schemes that would be utilized in the production process. The coding format used for digital emission is based on MPEG-2 MP@ML with a long group of pictures and a typical datarate of 4–6 Mbit/s. Therefore a transcoding with high quality is needed. The non-real-time method explained in this paper delivers a much better subjective picture quality in comparison with the first generation realtime encoding even with transparent ITU-R 601 inputs. Therefore by a given picture quality for emission the bit-rate needed for the datastream can be drastically reduced.
