 Valensi was an official of CCIF serving first as Secretary-General (1923–1948) and then as Director (1949–1956).All current widely deployed color television standards – NTSC, SECAM, PAL and today's digital standards – implement his idea of transmitting a signal composed of separate luminance and chrominance.Because his invention pre-dated the actual introduction of color television by so long, his patent was exceptionally extended to 1971.
