GERMAN

It is desirable to provide radio or television sets with a device that allows from any point and regardless of the respective location of the device to be able to make any necessary adjustments or corrections.

The known suggestions for solving this problem can be divided into about three groups: First, the group in which the controllers to be operated themselves via a cable from the device be sold out ·; second, the group in which the controller is motorized via a control unit to be served; thirdly, the group that divides the device into two parts, of which the one with the control elements provided device part is used for remote control.

These devices are used individually for both televisions and radios.

The combined ones now form a new category Radio television sets, for which remote controls so far only either to operate the television part alone or in conjunction with the trip contact a motor-controlled, automatic transmitter selection device with one in the television housing housed independent radio device have become known. However, the latter combination has the disadvantage that it does not allow controlled arbitrary tuning.

The subject of the invention is a particularly useful summary of some known arrangements to a new type of additional device for television receivers, which on the one hand allows remote control of the usual function of a television, ^{but on the other hand extends this 1} to a combined television and radio device, whose tuning and control functions also are included in the remote control.

According to the invention, the task set is dadKirch solved that the television set has a connection option for watilweise subsequent Connection of either a remote control device, which the Bedleniungselemente for the functions a television set (brightness, contrast, volume and an off switch, possibly also channel selection and fine tuning), or a supplementary device that, in addition to the aforementioned controllers additionally a radio receiver / 1 with switching device for the operating modes »television«, »radio reception« or »off«.

The operating voltages required for the radio receiver are taken from the power supply unit of the television set and depending on the operating mode also switched.

At least the audio output stage and the loudspeaker are put together, but possibly also the audio IF stages of the FS device for television and radio reception use together.

This achieves a device that is very small and handy in terms of dimensions, which, like the previous ones, for Televisions used remote controls after the first group to an appropriately prepared one TV can be connected, making this a full-fledged remote-controlled combination device willi. Another advantage is that the television receiver has no additional expense can be set up so that it can either be used as a pure television set with the option a normal remote control or works with the new additional device as a combination device, the additional device can therefore be bought later.

On the basis of picture 1, the schematic of a television receiver with the various connection options, the mode of operation is more precise described, namely 1 means the entire television set with the units 5 (TV part), 6 (sound part), 7 (power pack) and the symbolically simplified cable connections 8 to 21 for the remote control. In detail, the numbers mean the following connections:

8 = channel switch

9 = fine tuning

10 = brightness control

11 = contrast control

12 = audio NF or IF output of the television part

13 = audio NF or IF input of the audio section

14 = volume control "

15 = ground line

709 508/148

16 = anode voltage supply for the television part

17 = Anode voltage inadequate in the power supply

18 = heating voltage supply of the television part

19 = auxiliary signal output of the power supply

20 = power line to the power supply unit

21 = power line from the network.

When using the device as a pure television receiver without remote control, the connections are established by plugging in the short-circuit plug 2 12/13, 16/17, 18/19, 20/21 short-circuited,

If a device is to be used that allows remote control of the television set, then the short-circuit plug is removed and. the remote control accessory 3 connected, depending on the type of functions to be remotely controlled may contain:

22 = a device for motor or

via a step switch z, u actuating channel switching as well as one controller each

23 = for fine tuning of the channel switch

24 = for the brightness

25 = for the contrast variation

26 = for volume changes.

The connections 16/17 and 18/19 remain via the short-circuit clip contained in the plug short-circuited, while the connections 20/21 lead via a holder on the remote control and, if necessary be coupled with a signal lamp, which indicates the switch-on status.

By connecting the remote control 4 and the radio receiving part 38 contained therein, the TV set expanded to a combined device. The operating members 28 to 31 are with those of remote exciter 2 (22 to 25) are identical. In contrast, ports 12/13, 16/17, 18/19, 20/21 in the device and controlled by the switch 33 according to the respective operating mode "radio", "television" or »Off« switched over in such a way that in the »Broadcasting« mode line 13 is connected to the Volume and sound characteristics changing network with the controls 34 and 35 on the radio section switched on and the anode voltage 17 and the heating cable 19 switched to broadcasting will. At the same time, a heating voltage is generated via a heating transformer 37 that is also switched on generated, with which the tubes of the television sound part are heated.

In the »television« operating mode, on the other hand, line 12 of the television set with the ■ - thus also effective for television reception - control network 32 connected while the anode voltage 17 and the heating cable 19 to the corresponding connections 16 and 18 of the television set be switched. The heating transformer is in this position switched off. It is quite possible to save a few lines - if you are in the »Broadcast« mode the heating and anode voltage supply of the television part leaves switched on. Through the in Fig. 1 However, it is possible to use only those tubes in both operating modes to keep in operation, which are actually needed in order to on the one hand the tubes of the other part of the device to protect as well as to avoid mutual interference, on the other hand in the operating mode »broadcast« to reduce the power consumption considerably.

The mains switch 39 can be combined with the switch 33 so that it is automatically activated in the operating mode "Radio" and "television" switched on, but otherwise switched off is. The remote control add-on itself, for which illustration 4 in Figure 1 is only an example, can be expanded or simplified. B. the restriction of the radio part only represents the reception of the FM-modulated VHF radio. On the other hand but the device can also be provided with a timer or a connection for it or with combine with a record player or tape recorder. Furthermore, the remote control attachment can be in another Execution to be formed as a part of the television set that is normally organic, in the receiver inserted, but can be removed as a remote control if desired. picture 2 shows the corresponding variant of a television set with an opening for the remote control part, which is covered when the accessory is removed. The cable 40 is, in this embodiment expediently made detachable from the remote control part 4 and by a set of connector pins replaced in the TV.

Finally, Figure 3 shows another version of the remote control with a radio VHF part. the Numbers have the following meaning:

41 = housing

42 = floodlight scale

43 = Magic eye for voting display

33 = Toggle button set for the operating modes

»Radio«, »Television« and - »Off«

44 = Control button for station tuning

of VHF broadcasting

34 = volume control for VHF and television

together

35 = regulator for the sound variations (for radio and television, together) 11 = contrast regulator for television 10 = reverberation regulator for television 40 = connection cable
37 = heating transformer

45 = connector to the television set
