Technical Specifications for Television Films in the Federal Republic of Germany

The technical quality of film programs can reach an optimum only if the film and the television systems are properly adapted to each other. From the given requirements of a television system, desirable properties of film, with regard to contrast, transmission characteristics, resolution and graininess, can also be derived. Stable and nearly optimum performance in television can be obtained if contrast is kept smaller than with optical projection, and if closer tolerances are set to the transfer characteristics of the film. Technical specifications and measuring methods have been developed to meet these ends. Equipment has been designed to measure the density range (transfer characteristic), resolution (depth of modulation), and graininess (SNR) of films by methods comparable to television scanning. The introduction of technical specifications for television films and of uniform adjusting methods for the telecine chain led to stable conditions at the film transmitting. The standards for synchronous sound recording at shooting, editing, and at transmission are briefly discussed, and a new single film standard, 35 Commag, is recommended for prints to be transmitted.
