I'm not sure about building the NTSC <-> PAL converter, but I would not think it woule be trivial. If someone knows of such a device, I would also be interested, especially if it operates on 50/60 Hz. When I was in Japan earlier in the year, I noticed many of the newer VCR's that supported NTSC, PAL and SECAM. While in Germany a few months back, I saw many televisions that supported all three formats, but not many VCR's. I have not seen much of either in the United States. In case you are interested, I had compiled a listing (from the '89 WRTH) of many of the different broadcast formats: Country Name Country Code Power Primary Language TV System ============ ============ ====== ================ ========= China (PRC) 86 220/50 Putonghua,Amoy D/PAL China (Taiwan) 886 110/60 Chinese (Mandarin) M/NTSC Hong Kong 852 200/50 Chinese,English I/PAL Indonesia 62 127/50 Indonesian B/PAL Japan 81 VAR/VAR Japanese M/NTSC Korea (South) 82 100/60 Korean M/NTSC Malaysia 60 240/50 Bahasa Malaysia B/PAL Philippines 63 220/60 Philippine dialects M/NTSC Singapore 65 230/50 Malay,Chinese,Tamil B/PAL Sri Lanka 94 230/50 Sinhala,Tamil B/PAL Thailand 66 220/50 Thai BM/PAL Austria 43 220/50 German BG/PAL Belgium 32 220/50 Dutch,French,German BH/PAL Czechoslovakia 42 ???/50 Czech, Slovak DK/SECAM Denmark 45 220/50 Danish B/PAL France 33 220/50 French L/SECAM Germany (West) 49 220/50 German BG/PAL Germany (East) 37 ???/??
