Abstract

The method involves receiving data received over an Internet (1) from a head end (2), and receiving broadcasting and/or radio signals from the head end. The broadcasting and/or radio signals are encoded and modulated in the head end, and are supplied into a wiring network (8). The broadcasting and/or radio signals are included in the data, and that the data containing the broadcasting and/or radio signals are decoded by the head end. The broadcasting signals are supplied in a phase alternating line (PAL) format into the wiring network. An independent claim is also included for a device for distributing broadcasting and/or radio signals.

Description

Die Erfindung betrifft ein Verfahren und eine Vorrichtung zur Verbreitung von Fernseh- und/oder Radiosignalen.The The invention relates to a method and a device for distribution of television and / or radio signals.

Im Stand der Technik ist es üblich, Kabelnetze, welche für die Verbreitung von Fernseh- und/oder Radiosignalen vorgesehen sind, über sogenannte „Kopfstationen" zu speisen. Diese Kopfstationen müssen dazu ihrerseits mit diesen Fernseh- und/oder Radiosignalen versorgt werden. Dies geschieht üblicherweise auf dem Weg der Satellitenübertragung sowie terrestrisch und/oder leitungsgebunden.in the State of the art it is common Cable networks, which for The distribution of television and / or radio signals are intended to feed on so-called "headends" Headends need to be supplied in turn with these television and / or radio signals. This usually happens on the way of satellite transmission as well terrestrial and / or wireline.

Eine solche Kopfstation wandelt die empfangenen Fernseh- und/oder Radiosignale in ein für die Übertragung über das Kabelnetz gewünschtes Format. Üblicherweise besteht dieses gewünschte Format in einem analogen PAL-Format für analoges Fernsehen, in UKW für analoges Radio oder in ein DVB-C-Format für digitale Kabelübertragungen. Daraufhin werden die Fernseh- und/oder Radiosignale von der Kopfstation im gewünschten Format in das Kabelnetz eingespeist.A such headend converts the received television and / or radio signals in a for the transmission over the Cable network desired Format. Usually is this desired Format in analog PAL format for analogue TV, in FM for analog Radio or in a DVB-C format for digital cable transmissions. Then the TV and / or radio signals from the headend in the desired Format fed into the cable network.

DE 100 56 390 beschreibt unter anderem ein Verfahren, in dem eine Vielzahl von Netzwerkinterfacegeräten von einer Kopfstation über ein Kabelnetz mit Broadcast-, Internet- und weiteren Telekommunikationsdiensten versorgt wird. Diese Netzwerkinterfacegeräte sind jeweils einem oder mehreren Teilnehmeranschlüssen vorgeschaltet, beispielsweise in Form einer sternförmigen Gebäudeverkabelung. DE 100 56 390 describes inter alia a method in which a plurality of network interface devices are supplied from a headend via a cable network with broadcast, Internet and other telecommunications services. These network interface devices are each connected upstream of one or more subscriber lines, for example in the form of a star-shaped building cabling.

Weiterhin offenbart DE 100 56 390 in verschiedenen Ausführungen, die Daten an die Netzwerkinterfacegeräte digital zu übertragen und in den Netzwerkinterfacegeräten zu demultiplexen und/oder zu dekodieren. In einer anderen Ausführungsform werden nur Teile des Datenverkehrs digital übertragen und direkt oder indirekt an die einzelnen Netzwerkinterfacegeräte adressiert. Für andere Teile des Datenverkehrs wird die Möglichkeit erwähnt, „Broadcastdienste analog über die hierfür herkömmlicherweise vorgesehenen Bänder zu übertragen und an alle Anschlussstellen weiterzuleiten".Further disclosed DE 100 56 390 in various embodiments, to digitally transmit the data to the network interface devices and to demultiplex and / or decode in the network interface devices. In another embodiment, only parts of the data traffic are transmitted digitally and addressed directly or indirectly to the individual network interface devices. For other parts of the traffic, the possibility is mentioned "to transmit broadcast services analogously via the conventionally provided bands and forward them to all connection points".

Nachteile im Stand der Technik bestehen darin, dass die Fernseh- und/oder Radiosignalzuführung zu den einzelnen Kopfstationen mittels der eingangs erwähnten Übertragungswege aufwendig und teuer ist und dass gemäß der vorgenannten Methode jeweils ein Netzwerkinterfacegerät für einen oder mehrere Teilnehmeranschlüsse bereitgestellt werden muss.disadvantage In the prior art are that the television and / or Radio signal feed to the individual head stations by means of the transmission paths mentioned above is complicated and expensive and that according to the aforementioned method respectively a network interface device for one or multiple subscriber lines must be provided.

Die Aufgabe der vorliegenden Erfindung besteht folglich darin, die Signalzuführung zu den einzelnen Kopfstationen kostengünstiger und weniger aufwendig zu gestalten als dies im Stand der Technik der Fall ist, ohne den Benutzern dabei die Anschaffung und/oder Installation eines oder mehrerer weiterer Geräte zuzumuten.The Object of the present invention is therefore to the signal supply to the individual head stations cheaper and less expensive to design than is the case in the prior art, without the Users doing the purchase and / or installation of one or several other devices be expected.

Diese Aufgabe wird durch ein Verfahren und eine Vorrichtung gemäß der unabhängigen Ansprüche gelöst.These The object is achieved by a method and a device according to the independent claims.

Daraufhin werden die Nutzdaten entsprechend dem dafür vorgesehenen Format enkodiert, moduliert und in das Kabelnetz eingespeist.According to the invention on the Internet spread television and / or radio signals from the headend as a source for used the implementation. The headend decodes this television and / or radio signals corresponding to an IP-TV decoder and / or with an IP radio decoder. Then the payload will be corresponding for that format encoded, modulated and fed into the cable network.

Die erfindungsgemäße Vorrichtung besteht in einer Kopfstation, die mindestens einen IP-TV-Dekoder und/oder mindestens einen IP-Radio-Dekoder, mindestens einen entsprechenden Enkoder, der das Signal in ein gewünschtes Format umsetzt, und mindestens einen dazugehörigen Modulator umfasst.The inventive device consists of a headend that has at least one IPTV decoder and / or at least one IP radio decoder, at least one corresponding one Encoder, which converts the signal into a desired format, and at least one associated Includes modulator.

Ein Vorteil der Erfindung besteht darin, dass mit der erfindungemäßen Lösung ein TV-Programm kostengünstig weltweit verbreitet und von erfindungsgemäßen Kopfstationen weltweit genutzt werden kann.One Advantage of the invention is that with the erfindungemäßen solution TV program cost-effective distributed worldwide and of head stations according to the invention worldwide can be used.

Ein weiterer Vorteil der Erfindung besteht darin, dass kein zusätzliches Netzwerkinterfacegerät für einzelne Benutzer oder Benutzergruppen notwendig ist.One Another advantage of the invention is that no additional Network interface device for individual User or user groups is necessary.

Eine vorteilhafte Ausführung der Erfindung besteht darin, dass die Kopfstation die über das Internet empfangenen Fernsehsignale in ein analoges PAL-Format umsetzt und in das Kabelnetz einspeist.A advantageous embodiment the invention consists in that the head station over the Internet received television signals in an analog PAL format and fed into the cable network.

Eine andere vorteilhafte Ausführung der Erfindung besteht darin, dass die Kopfstation die über das Internet empfangenen Fernseh- und/oder Radiosignale in DVB-C umsetzt, zu einem Multiplex zusammenfügt und in das Kabelnetz einspeist.A other advantageous embodiment the invention consists in that the head station over the Internet broadcasts received TV and / or radio signals into DVB-C, merges into a multiplex and fed into the cable network.
