The 525-line progressive scan system (525P) is used as the input signal for EDTV-II in Japan, which is an NTSC-compatible letterbox transmission scheme. This signal is also used for the SDTV (standard-definition television) signal format in the US. Two 525P signal interface formats, 4:2:2P and 4:2:0P, have been standardised by SMPTE in the US, ARIB (Association of Radio Industries and Businesses, previously BTA) in Japan and ITU-R. The reasons for proposing these interfaces, as well as their advantages, are discussed in this paper.
