Abstract

The method involves returning IP address requests (internet pages and data requests) via an intelligent switching box, which forwards DVB-T signals with internet or data content to a connected PC/network area, making it viewable on a normal web browser. The returning of the connection to the DVB-T station and the DVB-T signal processing tasks can be performed in separate devices or within a handheld device or mobile telephone. Independent claims are included for the shortening of response times for internet users, and for the use of DVB-T signals.

Description

Stand der TechnikState of technology

DVB-T wird heute nur zur Übermittlung von TV-Signalen in digitaler Form verwendet. Eine Internetnutzung über DVB-T scheidet bisher wegen der nicht gelösten Problematik des Rückmeldekanales an die DVB-T Sendestation aus. DVB-T kann bisher nicht in beiden Richtungen (vom und zum Empfänger) genutzt werden, dadurch ist eine Nutzung für Internetanwendungen bisher ebenfalls nicht möglich! Die in ähnlicher Weise eingesetzte Satellitenanbindung für Internetuser ohne DSL-Anbindung, führt bisher zu langen Antwortzeiten und doppelten Kosten im Internetbereich, was für die Anwender nervig und teuer ist.DVB-T today is only for transmission used by TV signals in digital form. Internet use via DVB-T so far is due to the unsolved problem of the feedback channel the DVB-T transmitting station off. DVB-T can not so far in both directions (from and to the recipient) be used, this is a use for Internet applications so far also not possible! The in a similar way Manner used satellite connection for Internet users without DSL connection, leads so far too long response times and double costs in the internet area, what kind of the users are annoying and expensive.

Aufgabe der ErfindungTask of invention

Die Erfindung ermöglicht es durch Einsatz intelligenter Hardware und Regelkreise, DVB-T zur Anbindung von Usern an das Internet und an Datendienste zu verwenden, wobei die Antwortzeiten und die Kosten im Vergleich zu einer Satellitenanbindung deutlich reduziert werden. Außerdem muß beim Enduser nur eine zusätzliche Hardwarekomponente eingebaut werden, da bestehende DVB-T Bauteile in die Datenübermittlung einbezogen werden und nicht zusätzlich anderes Equipment notwendig wird (wie z.B. beim Satellitenverfahren). Die Erfindung kann die Installation von DSL auch in Gebieten überflüssig machen, wo dies technisch möglich wäre.The Invention allows It through the use of intelligent hardware and control loops, DVB-T for Connecting users to the Internet and to data services, the response times and costs compared to a satellite connection clearly be reduced. Furthermore must be at the end user only one extra Hardware component to be installed, since existing DVB-T components in the data transmission be included and not in addition other equipment becomes necessary (as for example in the satellite method). The invention can make the installation of DSL unnecessary even in areas where technically possible would.

Beschreibung der Erfindungdescription the invention

Bei normaler Breitbandanbindung von nicht DSL fähigen Internetteilnehmern über Satellit (z.B. Strato Verfahren) stellt sich als Problem für den Nutzer heraus, dass bis zum Aufbau der Satellitenverbindung wegen der großen Entfernung zum Satelliten, die Antwortzeit in einem Bereich liegt, die für den jeweiligen Nutzer sehr nervig und unzumutbar sind. Außerdem muss der Nutzer ein kostenintensives Equipment (Satellitenschüssel, Montage dieser Hardware, PC-Karte zur Rückführung des Signals usw.) bereitstellen, dabei kann dieses Equipment nur für die Anbindung zum Satelliten für Internetzwecke genutzt werden. Dazu kommen noch die doppelten Kosten für die Satelliten Anbindung über den Anbieter (z.B. Strato) und zusätzlich für die Nutzung des zurück zu führenden Kanals z.B. über die ISDN-Leitung. Die durch die ABLD-Beratung Anton Langwieser (nach unserem Wissensstand) erstmalig erarbeitete Lösung führt hier zu einer deutlichen Reduzierung der Antwortzeiten und darüber hinaus zu einer Kostenreduzierung für den Endanwender, da bestimmte Hardwarekomponenten sowohl für den Empfang von DVB-T Fernsehsignalen und zusätzlich für die Anbindung an das Internet genutzt werden sollen. Für den Endanwender ist somit nur der Montageaufwand für die Empfangsantenne (die meist aber bereits vorhanden ist und weiter genutzt werden kann), den DVB-T Empfänger (den er sowieso braucht) und eine Zusatzkomponente zur Rückführung der IP Adresse an den Internetanbieter zu bezahlen.at normal broadband connection of non-DSL-capable Internet subscribers via satellite (e.g., Strato method) turns out to be a problem for the user out that until the construction of the satellite link because of the great distance to the satellite, the response time is in an area appropriate for the particular Users are very annoying and unreasonable. In addition, the user must enter costly equipment (satellite dish, installation of this hardware, PC card for the return of the Signals etc.), this equipment can only for the connection to the satellite for Internet purposes are used. In addition there are the double costs for the Satellite connection via the provider (for example Strato) and additionally for the use of the leading back Channels e.g. above the ISDN line. The by the ABLD advice Anton Langwieser (after our knowledge) first developed solution leads here to a clear Reduction of response times and beyond to a cost reduction for the End user, because certain hardware components for both the reception of DVB-T television signals and additionally for the connection to the Internet should be used. For the end user is thus only the assembly work for the receiving antenna (which is mostly already available and can be used), the DVB-T receiver (which he needs anyway) and an additional component to return the IP address to the Internet provider to pay.

Technische Konzeption: Die grundsätzliche Bereitstellung der Internetseiten kann an der DVB-T Sendeeinheit per direkter Anbindung (also z.B. über Erdkabel) oder aber per Übertragung von einem exorbitalen Satelliten erfolgen. Um bei Verwendung des Satelliten nicht wieder lange Antwortzeiten in Kauf nehmen zu müssen, wird an der DBV-T Sendestation ein Pufferungsrechner zwischengeschaltet, der über die Auswertung der bisher angeforderten Internetseiten und deren Häufigkeit, einen Cache vorhält, d.h. die Seiten brauchen nicht bei jeder Anfrage neu vom Satelliten abgerufen werden. Die Aktualisierung des so gebildeten Puffers erfolgt automatisch in Zeiten, wo der Pufferrechner nicht mit Userabfragen belastet ist. Darüber hinaus vergleicht dieser Pufferungsrechner die ankommenden Seitenaufrufe mit dem vorhandenen Cache, sollten diese Seiten schon zwischengespeichert sein, werden Sie direkt an den Endanwender per DVB-T Signal weitergeleitet, sonst aktualisiert sich der Rechner über den Satelliten und leitet erst dann die Seiten weiter. Da der Pufferrechner nahezu in ständiger Verbindung mit dem Satelliten steht, bedarf auch die Anforderung von bisher nicht benötigten Seiten deutlich weniger Zeit, als wenn dies der Endanwender jeweils für sich selber machen müsste. Damit bei der DVB-T Sendestation entsprechende Internetseiten gewählt werden können, erfolgt über normale Leitungsanbindungen eine Rückführung an den Anbieter des DVB-7 Internetsignals in Form von IP Anforderungen. Diese wertet der Pufferrechner nach Reihenfolge des Eintreffens aus und sendet in digitaler Form die entsprechenden Seiten zum DVB-T Transponder. Da bei normaler Internetnutzung Pausen zwischen Anforderung von Seiten, deren Lesevorgang durch den Endanwender usw. gegeben sind, kann ein Transponder mehrere User gleichzeitig bedienen als Faustformel wird dabei angenommen, dass bei 1000 angemeldeten Usern nur 10 User wirklich gleichzeitig aktiv sind, also Daten übertragen werden müssen. Da über einen Transponder (wie beim Fernsehsignal) ca. 24 MBit/s übertragen werden, könnten also theoretisch 31 User gleichzeitig real aktiv sein, wobei jedem User dann immer noch 768 KBit/s zur Verfügung stehen würden. Umgerechnet auf einen Transponder wären somit gleichzeitig ca. 3000 angemeldete User mit dem Internetsignal zu versorgen, bevor die rechnerische Kapazität des Transponders erreicht wäre. Als neu zu erwerbende Hardwarekomponente benötigt der jeweilige User dazu noch noch eine Schaltbox, die einmal dass über einen normalen DVB-T Empfänger erhaltene Signal an den PC des Endusers weiterleitet und für den Internetexplorer verfügbar macht und außerdem die IP Anforderungen des Endusers über den rückführenden Kanal wieder an den Anbieter des DVB-T Internetdienstes sendet.Technical conception: The basic provision of the Internet pages can be done at the DVB-T transmitting unit via direct connection (eg via underground cables) or by transmission from an exorbital satellite. In order to avoid having to take long response times when using the satellite, a buffering computer is interposed at the DBV-T transmitting station, which holds on the evaluation of the previously requested websites and their frequency, a cache, ie the pages do not need for each request newly retrieved from the satellite. The update of the buffer thus formed takes place automatically in times when the buffer computer is not burdened with user queries. In addition, this buffering computer compares the incoming page views with the existing cache, if these pages are already cached, you will be forwarded directly to the end user via DVB-T signal, otherwise the computer updates itself via the satellite and then forwards the pages. Since the buffer computer is almost always in constant communication with the satellite, the requirement of previously unnecessary pages requires significantly less time than if the end user would have to do this for themselves. In order to be able to select corresponding Internet pages at the DVB-T transmitting station, normal return connections are used to return the provider of the DVB-7 Internet signal in the form of IP requirements. The buffer computer evaluates this according to the order of arrival and sends the corresponding pages to the DVB-T transponder in digital form. Since normal Internet use breaks between requesting pages whose reading process by the end user, etc., a transponder can serve several users at the same time as a rule of thumb, it is assumed that with 1000 logged in users only 10 users are really active at the same time, so data is transferred have to. Since about a transponder (as in the television signal) about 24 MBit / s are transmitted, so theoretically 31 users could be simultaneously real active, with each user then still 768 kbps would be available. Converted to a transponder would thus be at the same time to provide about 3000 registered users with the Internet signal before the arithmetic capacity of the transponder would be reached. As a newly acquired hardware component, the respective user also needs a switch box that forwards the signal received via a normal DVB-T receiver to the end user's PC and for the Internet Explorer makes available and also sends the IP requirements of the end user over the returning channel back to the provider of the DVB-T Internet service.
