manner. Only the strongest companies could be expected to survive in an atmosphere where stan-
dards are lacking. A successful standard promises a stable period of income to manufacturers
while giving users assurance of multiple sources during the active life of the product.

Standardization usually starts within a company as a way to reduce costs associated with parts

stocking, design drawings, training, and retraining of personnel. The next level might be a coop-
erative agreement between firms making similar equipment to use standardized dimensions,
parts, and components. Competition, trade secrets, and the NIH factor (not invented here) often
generate an atmosphere that prevents such an understanding. Enter the professional engineering
society, which promises a forum for discussion between users and engineers while down playing
the commercial and business aspects.

Of the many standards-setting organizations in the professional video field, the most promi-

nent are:

Society of Motion Picture and Television Engineers

Audio Engineering Society

National Association of Broadcasters

Electronic Industries Association

Advanced Television Systems Committee

Society of Cable and Telecommunications Engineers

Standards, whether for a new radio broadcast system or recorder connection pin assignments,

are vital for the continued growth of the audio industry.
