Broadcasting Telecasting (Jan-Mar 1960)

TECHNICAL PAPERS Progress in television tape techniques resulting from almost universal use by tv networks and stations will be woven with stereo, camera progress and automation in papers to be read at the 14th annual NAB Broadcast Engineering Conference to be held April 3-6 at the Conrad Hilton Hotel, Chicago. Warren L. Braun, WSVA-AM-FMTV Harrisonburg, Va., is chairman of the Broadcast Engineering Conference Committee that drew up the program. A. Prose Walker, NAB engineering manager, is conference arrangements director, aided by George W. Bartlett, assistant director. The three-day technical agenda opens the morning of April 4 with Raymond F. Guy, NBC senior staff engineer, presiding. After a single paper by Mr. Braun, in which convention exhibits will be reviewed, the delegates will join the NAB convention management group in a general session. They will join the management group at lunch also. Afternoon of April 4 will be devoted to a series of technical papers. Eight papers will be read the morning of April 5, to be followed by a joint engineeringmanagement luncheon. Exhibit Time • Afternoon of April 5 is left open for inspection of exhibits. This is a non-agenda afternoon for management delegates as well. The annual FCC roundtable, at which delegates join members of the FCC in informal discussion of industry problems, will be held 10:30 a.m. -12 noon April 6. At the joint engineering-management luncheon April 6, Mr. Walker will present the NAB Engineering Award to FCC Comr. T.A.M. Craven, a former consulting engineer. Eight more technical papers will be read that afternoon, followed by the annual banquet which is the last program event. A preview of the fifth edition of the NAB Engineering Handbook, to be published by McGraw-Hill Book Co., will be given by Mr. Walker on the opening afternoon. The 1,800-page volume, with 1 ,272 illustrations, has been in preparation three years. It embraces new technical developments and will be the standard technical reference work for broadcasters.

For the past three years, the NAB engineering department has been engaged in the preparation of the fifth edition of the NAB Engineering Handbook. This undertaking has resulted in Mr. Walker a handbook which consists of approximately 1,800 pages and 1,272 illustrations. The book is being published by the McGraw-Hill Book Co. and is the the only technical handbook of its kind that treats the entire broadcast system in a logical order, from antenna to studio. This paper will provide you with a "sneak preview" of the new handbook and explain how to use the material to maximum advantage. 3-3:25 p.m. "The Present Status of Stereophonic Broadcasting." by C.G. Lloyd, former chairman. National Stereophonic Radio Committee S t ereophonic broadcasting has received increased attention by broadcasters recently, and the FCC has proposed rule making looking toward the establishment of appropriate Mr. Lloyd transmission standards for stereo broadcasting on fm stations. The National Stereophonic Radio Committee has been engaged in a study of available systems and has submitted information to the FCC to aid in their consideration of the standards. This paper reviews the various systems which could be utilized and points out the considerations involved in determining transmission standards to be utilized by the industry. 3:30-3:55 p.m. "Sine Squared Pulses in Tv System Analysis," by Ralph Kennedy, development engineer, NBC. The history of the development of sine squared pulse testing as it has occured in Europe is traced followed by a comparison of heaviside step vs. sine squared pulse spectra and their effect on a system. Mr. Kennedy The methods of pulse generation are BROADCASTING, March 28, 1960
