producer of "Your Show of Shows," while the third is to be produced by Leland Hayward. Each series will be presented at the rate of one show a month—the Liebman productions scheduled for 10:30 to midnight on Satur- days and 7:30 to 9 p.m. on Sundays, and the Hayward productions from 8 to 9:30 p.m. on Mondays. The first will go on the air from 7:30 to 9 p.m. on Sunday, Sep- tember 12, featuring film star Betty Hutton in a special musical comedy written for her. This program also will inaugurate color TV broadcasting from the huge new NBC television studio in Brooklyn, N. Y. New Color Equipment The step-up in color broadcasting activity is being accompanied by other RCA advances in color equipment engineering and servicing, and in receiver manufacture. Joseph B. Elliott, Executive Vice-President, Consiuner Products, RCA, disclosed on June 10 that RCA Victor color television receivers to be introduced in the fall will employ the new and very latest RCA shadow mask 19- inch tube, using the full area of the tube face and pro- viding larger and brighter color pictures of approxi- mately 205 square inches. "The new tri-color tube will incorporate a recently developed 3-gun assembly, shorter and with higher effi- ciency, producing outstanding brilliance and picture quality with increased stability,' he said. "The new tube does not require any change whatsoever in the circuitry of the color receiver." In the field of color equipment, a new "3-V" camera developed by the RCA Engineering Products Division for telecasting color motion pictures made its debut on June 25, when NBC broadcast 35-mm film in color publicly for the first time in television history. Previ- ously only l6-mm film had been shown publicly in color television, and the new development was hailed by the press as a major forward stride in color TV and a vast improvement over all earlier color film presentations. The new camera employs three RCA Vidicon pickup tubes and a light-splitting optical system comprising two dichroic mirrors placed at angles in front of the projector. The first of the mirrors reflects the blue portions of the projected image to one of the Vidicons, permitting the red and green portions to pass through to the second mirror. The second mirror reflects the red portions to the second \ idicon and allows the green portions to pass through to the third Vidicon. Each of the Vidicon units generates a signal for bro.adcast representing its own color portion of the original image. The development of new equipment to speed instal- lation and maintenance of color receivers was announced by E. C. Cahill, President of the RCA Service Company. The equipment features a "color stripe generator" de- The versatility of color television was demonstrated by NBC during the spring with a colorcast from the Metropolitan Museum of Art. signed by the Service Company to transmit a video signal that will enable a service technician to determine whether a color TV set installed in a home is actually receiving color signals. Mr. Cahill said that the system, costing about S500, can be installed easily by TV broadcasting stations al- ready equipped to carry network color programs, and in other stations when they modify equipment to handle color. The test signal transmitted by the equipment con- sists of a narrow vertical yellow-green bar visible at the edge of the viewing screen on color sets, but practically invisible on the screen of a black-and-white set. Anas Sung and Acted Opera lovers long accustomed to listening to words they don't understand can now break through the lan- guage barrier by means of RCA Victor's new series of records titled "Arias Sung and Acted." The unusual twin packaging of the spoken word and song, conceived by George R. Marek, Director of Artists and Repertoire, RCA Victor Record Division, has re- sulted in a new album of famous arias acted in English by players of the legitimate stage and then sung in their original language by famous stars of the Metropolitan Opera. The acting and singing versions of the arias are portrayed in the new album by Judith Anderson and Rise Stevens, who are cast as "Carmen," Dennis King and Leonard 'Warren as "Rigoletto" and "Tonio;" Deborah Kerr and Licia Albanese portraying Mimi from "La Boheme" and Violetta from "La Traviata;" Dennis King and Robert Merrill as the Germont pere of "La Traviata," and Gerald ine Brooks and Joseph Cotton with Zinka Milanov and Jussi Bjoerling as "A'ida" and "Ra- dames."
