APPARATUS FOR REPRODUCING VIDEO SIGNALS WITH A SPEED WHICH DEVIATES FROM A NOMINAL SPEED |
摘要 |
A video recorder wich is adapted to reproduce video signals recorded on a record carrier in the form of a tape in tracks which are parallel to each other and which are inclined relative to the longitudinal axis of the record carrier with a speed which deviates from the nominal speed. The video recorder comprises tracking-error detection means for detecting the deviation of the read head from the centre of the track to be followed. The generated tracking-error signal is applied to the tape-transport control loop. For the purpose of tracking-error detection a reference-signal generator generates reference signals which form an identification for the track to be followed. For reproduction with a deviating speed these reference signals are generated in such a pattern that this pattern corresponds to the sequence of tracks which the head would scan in the case of a free uniform motion with a constant-tape transport speed which deviates from the nominal speed, so that when such a pattern is generated the tape-speed control will establish a tape-transport speed corresponding to this pattern. |
