Patent DE-4013078-A1 (DE)
Inventor: KLUTH HANS-JUERGEN DIPL ING
IPC: H04N5/782
Filed: 1990-04-25
Abstract: In novel television transmission systems like D2-MAC, for example, the signal quality is improved with regard to bandwidth and cross-talk. Some of this signal quality is lost when such a signal is recorded on an ordinary video recorder. The purpose is to construct a video recorder in such a way that high-quality recordings of such signals can be obtained without losing the quality parameters of the signal again thereby. The colour difference signals (R-Y, B-Y) are recorded line-sequentially by the frequency modulation of a carrier (Ft) with second magnetic heads (K2) with a wider gap in a deeper-lying layer (S2) of the magnetic tape (T). Especially for an S-VHS video recorder for recording D2/MAC signals.
