Abstract

In known remote-controlled electronic appliances for entertainment, the execution of a command is displayed on the appliance. The displays are sometimes difficult to read at distance. The aim of the invention is to provide the user with a visible display of essential information on the remote control unit itself. A sender arranged in the remotely controlled appliance comprises a control logic which transmits, cyclically and with intervening pauses, current operating and setting data of the appliance to the remote control unit, which is equipped with a receiver. These data can be read in a display field in the remote control unit. Application to remote-controlled electronic appliances for entertainment.

Description

For this 1 page drawing

It is known electrical equipment such. B. Hörrundfunkempfänger, television and video recorder with a wireless

controlling sending remote control unit. The remote control unit contains e.g. a radiant ray infrared or ·

Ultrasonic transmitter, the signals coded according to the individual functions to an infrared or infrared sensor located in the Gorfit Uchrallempfänger sondet. In this way, various functions of the device, such as switching on and off, The channel selection, volume, brightness and tape functions of a diode recorder are remotely controlled. Such remote control units require from the operator a certain skill and familiarization. The The operator can not easily tell if the command entered in the remote control unit is the device at all

erroicht, in particular, when a command receipt acknowledging display on the device from the distance from the user bad is recognizable. The user is therefore virtually forced, after each actuation of a remote control element to check whether the desired response to the device to be controlled really takes place.

From EP-patent 129 794 is a bidirectional system with a remote control unit and several, through them to

controlling devices known in which a transmitter is provided in the devices and a receiver is provided in the remote control unit.

In this system, to ensure remote control operation on the remote control unit, hereinafter called FB unit,

displayed, which of the devices is ready to receive. Further data will not be transmitted. '

It is an object of the invention, dom operators a clear display of required information to the To enable remote control self-sufficiency. This object is achieved according to the invention by the features listed in claim 1. Advantageous developments

The invention are characterized in the subclaims.

In principle, ads that z. B. in commercial VCRs on the front of the device over various Provide information on operating and setting states, transfer them from the device to the FB unit, and then display them on a display field

made. Thus, in extreme cases, a display on the device itself omitted, especially since the device is placed in many cases by the operator several meters away, so that the displays on the device are not or only poorly visible. The transfer of

Data from the device to the FB unit is made by a special item located in the unit, which is inserted in the FB unit Receiving part is assigned. The current operating and setting data are polled cyclically in the device by a control logic

and also transmitted cyclically with intervening pauses. In order to avoid spurious controls and false indications, the own receiver is locked both in the device and in the FB-unit during a data transmission of the own transmitter. The transmitter in the FB unit Pine precedence is given, which is given by the fact that the device transmits the data with intermediate pauses, so that in each case during a break, the receiving part is activated in the device.

Since the receiver is locked in the FB unit during command transmissions from the FB unit to the unit, the FB unit is in the FB unit

a memory for already received data available, so that even in this phase can follow ads in the display panel of the FB unit. In addition to these ads can z. B. also indicated the respective command output. For his

To ensure compliance with a clock located in the device and the time display on the remote control, the The clock is displayed directly, or a clock in the FB unit can be synchronized by the clock.

The example of a video recorder is intended to address conceivable annunciator clauses of the FB-Elnhelt:

A residence:

On, Off, Rec, Play, Stop, Channel, etc

 B drive data:

Tape counter reading, rust running time '. of the band etc

 C status data:

Time, date, timer and memory contents, etc

 ü 8 special employment data:

VPS, REC, Quickstart, Zlollauf etc.

In the following the invention will be explained in more detail by way of example with reference to a figure:

The figure shows a fernnbedienbares device 1 and oine associated FB unit 2. The device 11st equipped with a transmitting part 6 and a receiving part 5. Likewise, you FB unit 2 has a transmitting section 4 and a receiving section 7. In the FB unit 2 there is a keyboard 12, which is connected via line L 3 with a control logic 11, which may be designed as μΡ or pC. If 12 commands are entered by means of keyboard, which control the operation of the device 1, these ice data on line L 2 the Sendetet! 4 supplied. At the same time, a command is issued via the line L7 from the control logic 11, which blocks the ds receiving 7 in the FB-Einhoit 2 to avoid Fehlolngaben by the radiated from the transmitted 4 Datonbefehle. Via line L1, the radiated commands can be supplied to the annoying field 3 for the purpose of display.

The command issued via a data-modulated IR beam is picked up by the receiving section 5 located in the device 1, demodulated and fed as data stream via line L9 to the control logic unit 13 (μΡ or μθ) In addition, it is possible to visualize indications which are required via line L11 in the display panel 14. The control logic 13 is designed such that the output of data cyclically on line 10 to the transmitting part 6, are provided with intermediate pauses

 These breaks have Olgende function:

When transmitting data modulated on a carrier via the device end part β, the own receiving part 5 is blocked by the control logic 13 via line L12 to avoid Fehlestullungon by this data. However, since a command issued by the FB unit 2 is to be executed immediately, the receiving section 5 may not be locked when a command arrives. But now the transmission of data is clocked, d. H. provided with pauses, each receiving section 5 is activated during a break. If an instruction arrives during the activation phase, it is processed in the control logic 13. At the same time for the time of incoming signals, the output device-related data via line L10 to the transmitting part β by the control logic 13 is blocked. By choosing the pause clock must be ensured that oin entered by the operator in the keyboard 12 command falls with certainty in a "pause" of the device.

The data sent by Gorät 1 are supplied from the receiving part 7 in the FB unit 2 via line L8 a decoder circuit 8, demodulated in this, and from this via line L6 a memory 9, and a clock module 10, for triggering on the device in the first set time, fed. From memory 9, the current operating and setting data of device 1 via line L5 reach the control logic 11, from which the displays on display field 3 are controlled via line L1. Also, the clock information from clock module 10 via Leituno L4 of the control logic 11 for display on display panel 3 is supplied.
