Abstract

A monitor with integrated ISM-band receiver for audio/video signals and integrated ISM transmitter for remote control signals. The monitor, ISM-band receiver and ISM band transmitter are supplied from one power source. The ISM band receiver and ISM band transmitter specifically operate on different channels.

Description

Schon seit längerer Zeit sind Audio-/Videoübertragungssysteme (z. B. in 2,4 GHz Band) für den Bereich der Unterhaltungselektronik erhältlich, die das dafür vorgesehene ISM-Band zur Übertragung nutzen. Ebenfalls sind schon seit längerem Systeme zur Bildung eines Fernbedienungsrückkanals erhältlich. Hierbei werden die Signale einer Infrarot-fernbedienung in Funkwellen umgewandelt und im Frequenzbereich des ISM-Bandes zu einem entsprechenden Empfänger übertragen, welcher die Funksignale wiederum in ein Infrarotsignal umwandelt. Über solche Systeme können mittels einer Infrarotfernbedienung auch ohne die sonst übliche direkte Sichtverbindung die entsprechenden Geräte ferngesteuert werden. Ebenfalls sind schon seit längerem Kombinationsprodukte von diesen beiden Systemen auf dem Markt. Der Anschluss dieser Systeme an ein Wiedergabegerät, zum Beispiel Fernsehgerät oder TFT/LCD-Monitor erfolgt üblicherweise über eine oder mehrere Anschlussleitungen. Ebenfalls ist es üblich, dass sowohl Wiedergabegerät als auch Übertragungssystem über separate Stromversorgungen und entsprechend separate Anschlusskabel bzw. Steckernetzteil verfügen. Als Folge davon entsteht beim betriebsfähigen Anschluss der einzelnen Geräte aneinander eine aufwendige Verkabelung, die sowohl aus ästhetischen Gesichtspunkten als auch aus technischer Sicht unvorteilhaft ist. So ist zum Beispiel, bedingt durch die Verkabelung, kein mobiler Betrieb möglich.Audio / video transmission systems have been around for a long time (e.g. in the 2.4 GHz band) for the area of consumer electronics available, which the intended Use ISM band for transmission. Also have been around for a long time Systems for forming a remote control back channel available. The signals from an infrared remote control are transmitted in radio waves converted and in the frequency range of the ISM band to a corresponding Transfer recipient, which in turn converts the radio signals into an infrared signal. About such Systems can by means of an infrared remote control even without the usual direct Line of sight the corresponding devices can be remote controlled. Likewise have been around for a long time Combination products from these two systems on the market. The Connection of these systems to a playback device, for example a television or TFT / LCD monitor usually takes place via an or several connection lines. It is also common for both the playback device and the transmission system to have separate Power supplies and corresponding separate connection cables or plug-in power supply feature. As a result, when the individual is operationally connected equipment complex cabling that is both aesthetic Aspects as well as from a technical point of view is disadvantageous. For example, due to the cabling, there is no mobile operation possible.

Sinn und Zweck der im Folgenden vorgestellten Erfindung ist es, die vorgehend beschriebenen Nachteile zu eliminieren mit dem Ziel, auch einen mobilen Betrieb zu ermöglichen. Hierzu werden Anzeigegerät, also das Fernsehgerät bzw. der TFT/LCD-Monitor mit dem ISM-Bandempfänger für Audio-/Videosignale und dem ISM-Bandsender für die Fernbedienungssignale in einem Gehäuse zusammengefasst und über eine gemeinsame Stromversorgung gespeist. Hierdurch entfallen die sonst üblichen aufwendigen Verkabelungen mit den schon geschilderten Nachteilen. Die Abbildung 1 zeigt eine entsprechende Ausführung der Erfindung. Hierbei werden die im ISM-Band abgestrahlten Audio-/Videosignale von der Antenne (1) empfangen und von dort dem Empfangsteil (2) zugeführt. Dieses bereitet die Signale entsprechend des Monitors (3) auf, so dass hier eine Wiedergabe erfolgen kann. Die Steuerung der senderseitigen Audio-/Videoquelle erfolgt über den Infrarotempfänger (4), der die Infrarotsignale der Fernbedienung empfängt, diese in elektrischer Signale umwandelt und dem ISM-Sendebaustein (5) zuführt. Hier erfolgt die Modulation der elektrischen Fernbedienungssignale auf einen Kanal des ISM-Bands, welches der Sendeantenne (6) zugeführt wird. Sowohl der Monitor (3) als auch der ISM-Empfänger (2) und der ISM-Sender (5) sowie alle damit verbundenen Komponenten werden über die Stromquelle (7) versorgt.The purpose of the invention presented below is to eliminate the disadvantages described above with the aim of also enabling mobile operation. For this purpose, the display device, that is to say the television or the TFT / LCD monitor with the ISM band receiver for audio / video signals and the ISM band transmitter for the remote control signals, are combined in one housing and fed via a common power supply. This eliminates the otherwise usual complex cabling with the disadvantages already described. The image 1 shows a corresponding embodiment of the invention. The audio / video signals emitted in the ISM band are transmitted from the antenna ( 1 ) received and from there the receiving part ( 2 ) fed. This prepares the signals according to the monitor ( 3 ) so that playback can take place here. The control of the transmitter-side audio / video source takes place via the infrared receiver ( 4 ), which receives the infrared signals from the remote control, converts them into electrical signals and sends them to the ISM transmitter ( 5 ) feeds. Here, the electrical remote control signals are modulated on a channel of the ISM band, which is the transmission antenna ( 6 ) is supplied. Both the monitor ( 3 ) as well as the ISM recipient ( 2 ) and the ISM transmitter ( 5 ) and all related components are powered by the power source ( 7 ) provided.
