Proposed American Standard 16mm Motion Picture Projector for Television
J. HE INITIAL WORK on this proposal was done by an RMA Subcommittee, TR4.4.2, and a first draft was circulated in May 1950. Need for extensive revision was indicated at the final meeting of TR4.4.2 held in June 1 950. At about this time, the present Joint RTMA/ SMPTE Committee on Television Film Equipment was organized to replace the RMA Subcommittee.
At the first meeting of the Television Film Equipment Committee, the proposal was again reviewed and revised and a second draft incorporating the desired changes was circulated in September 1950. The extensive nature of the proposal precluded ready agreement, and a third draft, February 1951, and a fourth draft, May 1951, were required before the committee could reach final agreement. The latter was then submitted independently to the RTMA and the SMPTE Standards Committee for further action.
In the RTMA, the proposal TR4-4116 was accepted by TR4, approved for circulation to industry by TREX and
released as Standard Proposal #365 in June 1952.
In the SMPTE, the Standards Committee balloted on the question of approving Journal publication of the proposal for a 90-day period of trial and comment and, with but a few exceptions, voted affirmatively. The negative votes were based on the objection that the proposal was more of a procurement or performance specffication than a standard defining required dimensional limits for the purpose of aiding interchangeability. With the belief that publication would stimulate worth-while discussion, the Standards Committee gave the necessary approval in June 1952.
Please send comments, in duplicate, to Henry Kogel, Staff Engineer, before December 15, 1952. If no adverse comments are received during the threemonth trial period, the proposal will be submitted directly to ASA Sectional Committee PH22 with the recommendation that it be processed as an American Standard.
