- the DVHS video recorder is connected to the set top box by a cable connection adapted to be connected to digital connection means of the DVHS video recorder, the digital connection means enabling A/V data and control data containing digital audio, video and control information to be transferred.
- the DVHS video recorder has reproducing means and is adapted to reproduce analog A V signals in accordance with the VHS standard from a magnetic tape in an analog mode of operation and to reproduce digital A V data in accordance with the DVHS standard from said magnetic tape in a digital mode of operation.
- the known DVHS video recorder further has OSD generator means adapted to generate and supply text information for on-screen display as A/V information.
- the DVHS video recorder has an OSD insertion stage by means of which an A/V signal generated by the OSD generator means can be inserted into an A/V signal reproduced by the DVHS video recorder or applied to the DVHS video recorder via its analog connection means, in order to insert the on-screen display information generated by the OSD generator means into video information for the joint display of said information by means of the television set.
- the known DVHS video recorder can be employed in accordance with two possibilities of use in order to insert on-screen display information into video information reproduced as A/V data in the digital reproducing mode of the DVHS video recorder and jointly display said information by means of the television set.
