Abstract

Color decoding device for signals emitted by an NTSC source for the purpose of coding in any system, characterized by the use of a shifter operating at a reference frequency receiving signals in series and transmitting 4 parallel bits to a carrier which samples them at a frequency equal to one fourth of the reference frequency. The signals and their complements produced by the sampler are transmitted to a display device through a matrix of interchangeable resistors. The invention applies to all coding systems, especially SECAM, and in particular to the SECAM display of signals emitted by NTSC computers.
