Text IIColour television signals can be transmitted over the same distance as monochrome television signals since the radio-frequency carrier frequencies in colour television transmission are the same as in black-and-white transmission. Colour video information in the signal being transmitted does not change the operational characteristics of the television receiver. The structure of a colour television receiver is far more complex than that of a monochrome one. Naturally, it requires more servicing than a monochrome receiver. As to the power consumption, the colour television receiver consumes more power than the black-and-white receiver. To be exact, it consumes about one and one-half times as much power. It is natural that it should consume more power because it contains more receiving tubes and circuits.' The total power consumption of a colour television receiver is between 300 and 400 watts while that of a black-and-white — from 150 to 250 watts. It is practically impossible to convert a black-and-white receiver to receive colour broadcasts. To do it would require a great deal of special components since the colour tube and its auxiliary parts are very special. At the same time a colour television receiver does not require any special antenna or other components as a part of installation. The antennas now in common use with a monochrome television receiver will be usable with the colour receiver provided that the station or stations transmitting colour programs are the same as those transmitting monochrome pictures. Thus, there is no need to produce special antennas for colour television reception. Provided that the colour television receiver is tuned to the frequency of the monochrome transmitter, it reproduces monochrome transmissions.
