Abstract: The advent of high-performance electromechanical servo systems and of an electronically variable delay-line (EVDL)-type time-base corrector for videotape recorders (VTRs) made recovery of a properly phased color video possible in the early 1960s. The development of the video digitization and memory technique in the late 1960s produced a digital time-base corrector (DTBC) of expanded capture range at a commercially acceptable cost. Use of VTR systems with the color-under technique, with its acceptable color video performance, operational economy and simplicity, has become widespread in many non-broadcast fields as well as in the electronic newsgathering field. An important application of DTBC is for color-under VTRs, and many variations of DTBCs are being developed to further improve the performance when used with VTRs. A DTBC is also a useful ancillary element of high-performance VTRs, including quadruplex types.
