Abstract

Part I of this paper included the fundamentals of the Columbia Broadcasting System color-television system and the general application of colorimetry to color television. The equipment used in this color method was described. Part II deals with improved receiver-tube phosphors and the attendant changes in transmitter color characteristics. The color-reproduction theory is extended to include changes in gamma and the action of the color mixer. An automatic color-phasing system is described. Sixty-cycle interference in viewing tubes and its prevention are reported as investigated. Work on the problem of increasing definition of color television by use of a wider frequency band is described, and some considerations of certain possibilities of large-screen color-television pictures are given.
