Abstract :
In electronic video recording (EVR),¿ the color television signals are recorded on a special 8.75-mm-wide, high-resolution photographic film, with two frames side by side. One frame contains luminance information; the other, coded chrominance information. Sound is recorded on two magnetic edge stripes. An 18-cm-diameter cartridge can play 25 minutes of color programming or twice that duration of black-and-white programming. Described in this article are the processes that, starting from an original program on video tape, produce a reproduction with excellent fidelity upon playback. A detailed explanation is provided of the mechanical, optical, and electronic arrangements¿including the transcoding of the chrominance signal into a conventional color television signal.
