Ahronheim s invention transmits the picture with varying *ave-lengths. The person receiving th® picture may employ as limited or ranges of wave-lengths as he de•ires, thus seeing only the main colours or receiving the whole gamut d°wn to delicate shades. Herr Ahronheim also asserts that he has solved the problem of placing the Moving picture before the receiver toll-size.
