Color TV broadcast studio, above, was feature of RCA exhibit at the NARTB convention. At right, a model of the exhibit is studied by T. A. Smith, center, Vice-President and General Manager, RCA Engineering Products Divi- sion, with A. R. Hopkins, left, Manager, Broadcast Equipment Marketing, and John P. Taylor, Manager, Advertising and Sales Promotion. New Aids to Color TV Broadcasting T J-HREE new developments that promise greater flexibility, economy and efficiency in color television broadcasting were introduced by RCA during May at the annual convention of the National Association of Radio and Television Broadcasters in Washington. The developments include: 1. A new-type studio color TV camera that costs 25 per cent less than previous RCA color camera equip- ment, while offering savings in operating costs, studio space, and maintenance; 2. A new universal multiplexer which integrates monochrome and color projection facilities, permitting broadcasters to use a single multiplexer and the same projectors for televising both color and monochrome slides and films; 3. Special color-effects equipment that will enable broadcasters to originate television commercials, pro- gram titles, and station identification in color from black-and-white slides and art work. Developed by the RCA Engineering Products Divi- sion, the new equipment was shown in a completely equipped color TV broadcast studio installed for the NARTB meeting. The studio formed the major feature of an overall exhibit which also included RCA's new "Ampliphase" AM radio broadcast transmitter and a versatile, high-power broadcast microwave system cap- able of delivering stronger and more stable TV signals over greater distances than comparable equipment. The new RCA color TV studio camera incorporates a revolutionary "all-in-one" signal processing amplifier which combines and performs all signal processing func- tions and eliminates various components, according to A. R. Hopkins, Manager, Broadcast Equipment Market- ing, of the RCA Engineering Products Division. Com- pared with previous color camera equipment, the new model offers a number of important advantages, Mr. Hopkins said. Among these he emphasized that the new camera equipment requires little more studio space than do black-and-white camera chains, employs 134 fewer electron tubes, and eliminates 50 per cent of the DC power supplies required previously. Discussing the new color-effects equipment, Mr. Hopkins emphasized its value to television stations now equipped to transmit network color programs. At the present time, such stations return to black-and-white during station breaks in network programs, unless they happen to be equipped with live or film color cameras. With the new equipment, however, they will be able to add electronically up to 24 different pre-selected colors to the black and to the white portions of a picture. 78 RADIO AGE
