Digital tape recording in ATV video formats using the commercially available 1125 line recorders

摘要

Six advanced television (ATV) transmission systems are being tested. These systems provide video signal inputs in the form of red (R), green (G), and blue (B) in analog form. One system requires 1125-line, 60-field/s interlaced video, two require 1050-line, 59.94-field/s interlaced video, two require 787.5-line 59.94-field/s noninterlaced video, and one requires 525-line, 59.94-field/s noninterlaced video. Digital video tape recording of RGB video in all proposed ARV formats has been implemented on the digital video tape recorder (DVTR), which was designed for the SMPTE-240-M video format. This required the development of a format converter, which is described.
