When planning an instructional television (ITV) system, it is suggested that educational objectives should outweigh technological considerations and that expert advice be secured before the planning process is far advanced. In line with the latter suggestion, the book offers a background of technical knowledge aimed at educational administrators who are involved in planning an ITV system. The possible uses for an ITV system and some overall planning considerations are surveyed. The test pattern concept for assessing the quality of a television picture is explained, and descriptive definitions offered of some basic ITV terms, such as broadcast quality, cable television, microwave, etc. Planning considerations for studios and studio equipment are outlined. Transmission options--open-circuit, cable, instructional television fixed service--are described, as are the links in the television reception chain--preamplifiers, modulated radio frequency systems, etc. Quadraplex videotape recorders are compared with slant-track recorders. Advice on preparing for color capability and on assembling an ITV staff is given. A basic planning pattern details the personnel who should be involved in the design stage and estimates the initial costs of an ITV system. (JY)
