Abstract
456,584. Television. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Electra House, Victoria Embankment, London, and RUST, N. M., 109, London Road, Chelmsford. May 11, 1935, No. 13913. Drawings to Specification. [Class 40 (iii)] A transmission system for television signals comprises a cable transmission system adapted to give substantially constant time delay for all the signal frequencies above approximately the scanning line frequency, means at the output end of separating out desired low frequencies below that for which the cable system gives substantially constant delay and imposing on the low frequency signals an additional delay so that relative to the picture, i.e. highfrequency signals, they are delayed by one or more picture frame periods. The delayed low frequencies, which include the framing frequency and harmonics thereof, and the high frequencies are combined and fed to a television receiver or to a rediffuser. The cable is preferably of the air-spaced coaxial conductor type.
