摘要： Letter-box television signals of 16:9 image format compatible with 4:3 receivers may contain, in the two edge strips above and below the active image, additional information needed by a 16:9 receiver in order to reproduce an image with a resolution close to that of the source signal. This additional information may be modulated on the colour carrier and therefore become unusable when recorded on a video recorder (approx. 600 kHz chrominance bandwidth). If the additional information is recorded in the edge strip lines, e.g. in S-VHS video recorders in combination with corresponding switchovers via the luminance channel, the entire bandwidth (about 5 MHz) of the additional information is retained.

摘要： The bandwidth of the brightness signal in S-VHS video recorders is increased by some 5.15 MHz. However, the bandwidth of the recorded colour signal is still only +/- 0.5 MHz. The aim is to obtain colour recording with an increased bandwidth and hence sharper colour reproduction with a greater signal-to-noise ratio. The modulated colour carrier (F) is recorded with second heads (K2) with wider gaps in a deeper-lying layer of the magnetic tape (T). Especially for S-VHS video recorders.

摘要： 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.
摘要翻译：在诸如D2-MAC的新电视传输方法中，从带宽和串扰的角度来看，信号质量得到改善。当利用现有类型的视频记录器记录这样的信号时，该信号的质量部分地再次丢失。本发明的目的是开发一种允许这些信号的良好记录的视频记录器。而不会由于记录而再次丢失信号质量参数。色差信号（RY，BY）通过载波（Ft）的FM调制通过具有更大间隙宽度的第二系列磁头（K2）以逐行方式逐行记录磁带（T）的深（S2）。特别适用于记录D2-MAC的S-VHS VCR。

摘要： The aim of the invention is to record, using a VHS video recorder, not only the main but also the auxiliary signal for high-definition TV reproduction. The auxiliary signal (Z) is recorded using second magnetic heads (K2) with a greater gap separation than that of first magnetic heads (K1) in a second magnetic layer (S2) lying under the first magnetic layer (S1). The invention is intended for use in S-VHS video recorders with high-definition TV recording facilities.

摘要： A NICAM sound carrier is transmitted which is modulated with digital sound signals. The purpose is so to construct a VHS video recorder that this sound carrier can be recorded in addition to the other signals without adversely affecting the quality. The NICAM sound carrier is therefore recorded in a deeper layer (S2) with second magnetic heads (K2) in frequency multiplex with EM sound carriers (T1, T2) at lower frequency. Usable especially for an S-VHS video recorder with multi-standard sound recording.

摘要： In a VHS or S-VHS video recorder the colour signals are recorded with the 'colour under' colour substrate only over a restricted bandwidth of some 0.5 MHz. It is the purpose of the invention to facilitate high-grade simultaneous recording of the RGB signals. Each video head (K1, K2) is replaced by two heads (K1a, K1b, K2a) of half track width (B/2) and the RGB signals are recorded by these heads in an upper (S1) and a lower layer (S2) of the magnetic tape (T). Especially for an S-VHS video recorder for the high-grade recording of D2-MAC signals.

摘要： In a vehicle such as an automobile, the reproduction loudness of a road traffic broadcast is switched over to a preset value by means of an identification signal from the broadcast transmitter. To facilitate understanding of the road traffic message, the basses and trebles are also switched over automatically to a preset value when the loudness is switched over. Useful in particular as a radio receiver in a motor vehicle.

摘要： The aim of the invention is to provide a circuit for processing a brightness signal, giving a maximum improvement in the signal, in particular with respect to picture definition and decomposition of the colour carrier signal. The so-called FBAS signal is fed to an adaptive comb filter (K). The filter output is connected to the input of a circuit designed to increase picture definition, this circuit having two differentiation stages, each with an amplitude limiter or an aperture corrector. The brightness-signal processing circuit is of use particularly in so-called S-VHS video recorders and TV receivers.
