We carried out a picture quality subjective assessment test regarding coding efficiency and service bit rate of 525P images.. As a result, we found that a high quality 525P service is feasible at a video bit rate of around 9Mbps with MPEG-2 video coding. We also concluded that, at such bit rate, the 525P format is more advantageous than 1125-interlaced in terms of picture quality.
