A playback device of the type described above is known from the cited document WO 97/10682 and takes the form of a DVHS video recorder. Known DVHS video recorders are:
This cable is connected to the television set by a cable connection adapted to be connected to the analog connection means of the DVHS video recorder and to the set top box by another cable connection adapted to be connected to the analog connection means. The connection allows analog audio and video information to be transferred as A / V signals.

[0003] A DVHS video recorder is set-top by a cable connection adapted to be connected to the digital connection means of the DVHS video recorder.
A / V data and control data including digital audio, video and control information can be transferred by the digital connection means connected to the box. The DVHS video recorder has a reproducing means for reproducing an analog A / V signal conforming to the VHS standard from a magnetic tape in an analog operation mode and digital A / V data conforming to the DVHS standard from the magnetic tape in a digital operation mode. Adapted to play.

[0004] Conventional DVHS video recorders have OSD generation means adapted to generate and supply text information for on-screen display as A / V information. In addition, the DVHS video recorder has an OSD insertion stage for inserting the on-screen display information generated by the OSD generation means into the video information for composite display using a television set, Using the OSD insertion stage, the A / V signal generated by the OSD generation means is inserted into the A / V signal generated by the DVHS video recorder or supplied to the DVHS video recorder via the analog connection means. .

[0006] According to a first usage of a conventional DVHS video recorder, the reproduced digital A
The / V data is supplied to the set top box via the digital connection means, and is decoded into an analog A / V signal by the decoding means. For insertion of an on-screen display, the DVHS video recorder supplies control data to the set top box via different connection means. This control data identifies the given on-screen display information stored in the OSD generation means of the set top box. Next, the OSD generating means supplies an A / V signal including the on-screen display information to an insertion stage of the set top box, and the insertion stage transmits the on-screen display information to the D-stage.
In order to insert the A / V signal into the video information reproduced by the VHS video recorder and display the information in a composite manner using a television set, the supplied A / V signal is converted into the A / V signal supplied from the decoding means. insert.

[0007] A first use of this conventional DVHS video recorder is in on-screen display items that are stored in the OSD generation means of the set-top box and are not compatible with the special features of the DVHS video recorder. Has the disadvantage that the number of on-screen display items that can be displayed using a television set is greatly limited by the provision of control data by a DVHS video recorder. Thus, for example, programming the timer of a DVHS video recorder or on-screen display of the contents of a video cassette is virtually impossible.

According to a second use of the conventional DVHS video recorder, the reproduced digital A
/ V data is supplied to the set top box via the digital connection means, and is decoded into an analog A / V signal using the decoding means.
The signal is supplied to the analog connection means of the DVHS video recorder as a V signal. In the OSD insertion stage of the DVHS video recorder, A containing the on-screen display information generated by the OSD generator of the DVHS video recorder
