ABSTRACT: A transmission system for a colour television signal, in particular a system for recording on and re- producing from a record carrier. The chrominance signal is divided into two separate colour signals, which in a line-sequentially alternating fashion are modulated on two separate colour carrier waves. The transmitted or recorded colour television signal can simply be transformed into both a standard PAL and a standard SECAM signal. Owing to the line sequential alternation of the colour signal, colour errors which may arise owing to a mutual difference of the transfer charac- teristics for the two colour signals are automatically, compensated for in the case of reproduction via a PAL receiver.
