The Problem:

If people want to record a film by means of the video recorder while not being at home, very few only make use of the very longwinded programming of start, end, date etc. because it is really too complicated and because errors are likely to be made. It is much more simple to put in an empty cassette and e.g. to press the record button already two hours earlier (just before leaving home). With new hard-disk video recorders which become increasingly available, this behavior will even increase, because it is possible to start recording already five hours earlier and later to delete again by keystroke.

The only problem is that of finding the beginning of the corresponding film when replaying a longer recording. It is right that the latest digital means of storage, DVD and hard disk, have the one big advantage of enabling, at least theoretically, to access any position very fastly without annoying spooling, like it was usual regarding VHS video recorders. Practically, however, this advantage can still not be made use of by means of available devices because the operation is much too long winded. Most of the hard-disk video recorders allow jumping to any position of a recording by entering the corresponding time, but this requires a succession of up to seven keys which must be pressed (firstly GOTO key, then the individual figures for exact time and date, finally the enter key). Furthermore, it is necessary to know the exact time for the searched position which is usually unknown. The only possibility left is to enter a time on the chance and due to the position, which is played then to estimate how much to jump forward or reverse. It is possible to enter another time on chance and to further search for the exact position (e.g. the beginning of the requested film) by using the fast picture search.

However, this all is very complicated and long winded. Finding exactly the position to the second where the searched film starts within a recording of several-hours duration, usually takes some minutes.
