Description
15 20 25 30 35 504 237 2 abonnenten när denne vill ändra det utbud han vill kunna mottaga. 15 20 25 30 35 504 237 2 the subscriber when he wants to change the offer he wants to be able to receive.
Föreliggande uppfinning undanröjer dessa nackdelar och erbju- der ett förfarande som är mycket enkelt att handha.The present invention obviates these disadvantages and offers a method which is very easy to handle.
Föreliggande uppfinning hänför sig således till ett förfaran- de för att selektivt utsända information via radiosändare, där en abonnent har en radiomottagare innefattande en dekoder som är anordnad att dekodera en mottagen radiosignal och om- vandla denna till en videosignal som påföres en TV's antenn- ingång, och utmärkes av, att en eller flera tjänster i form av information utsändes, där varje tjänst som utsändes inne- fattar en kod för tjänsten ifråga av, att för att abonnenten skall kunna mottaga en tjänst utsändes en signal innefattande en identitetskod för en viss bestämd mottagare samt en tjäns- tekod för var och en av de tjänster som skall kunna mottagas av, att dekodern bringas att lagra nämnda tjänstekod och av, att dekodern bringas att dekodera endast den information som tillhör en lagrad tjänstekod.The present invention thus relates to a method for selectively transmitting information via radio transmitters, wherein a subscriber has a radio receiver comprising a decoder which is arranged to decode a received radio signal and convert it into a video signal which is applied to the antenna input of a TV. , and is characterized in that one or more services in the form of information are transmitted, where each service transmitted contains a code for the service in question, that in order for the subscriber to be able to receive a service, a signal is transmitted comprising an identity code for a certain receiver and a service code for each of the services that can be received by the decoder being caused to store said service code and by the decoder being caused to decode only the information belonging to a stored service code.
Nedan beskrives uppfinningen närmare delvis i samband med ett på bifogade ritning visat utföringsexempel av uppfinningen, där figur 1 schematiskt visar en anordning för uppfinningens tillämpning.The invention is described in more detail below in part in connection with an exemplary embodiment of the invention shown in the accompanying drawing, in which Figure 1 schematically shows a device for the application of the invention.
Föreliggande förfarande för att selektivt utsända information avser utsändning via radiosändare. Varje abonnent som skall mottaga information har en radiomottagare 1 innefattande en dekoder 2 som är anordnad att dekodera en mottagen radiosig- nal och omvandla denna till en videosignal. Videosignalen på- föres en TV's 3 antenningång 4. Radiomottagaren är ansluten till en mottagningsantenn 5. Lämpligen utföres radiomottaga- ren så att denna tillsammans med dekodern bildar en enda en- het, såsom antyds med den streckade linjen i figur 1. Vidare kan radiomottagaren vara så utförd att den antennkabel 6 som löper från en ordinarie TV - antenn 7 löper in i radiomotta- 10 15 20 25 30 35 504 237 l garen och att det endast löper en kabel 8 från radiomottaga- ren till TV:n. Radiomottagaren kan härvid vara anordnad att avge endast nämnda videosignal via kabeln 8 till TV:n när »radiomottagaren är påslagen och att avge antennsignalen i kabeln 6 via kabeln 8 när radiomottagaren är avslagen.The present method for selectively transmitting information relates to transmission via radio transmitters. Each subscriber to receive information has a radio receiver 1 comprising a decoder 2 which is arranged to decode a received radio signal and convert it into a video signal. The video signal is applied to a TV 3 antenna input 4. The radio receiver is connected to a reception antenna 5. Preferably, the radio receiver is designed so that it together with the decoder forms a single unit, as indicated by the dashed line in Figure 1. Furthermore, the radio receiver may be so designed that the antenna cable 6 running from an ordinary TV antenna 7 runs into the radio receiver 10 15 20 25 30 35 504 237 l the receiver and that only one cable 8 runs from the radio receiver to the TV. The radio receiver can in this case be arranged to transmit only said video signal via the cable 8 to the TV when the radio receiver is switched on and to transmit the antenna signal in the cable 6 via the cable 8 when the radio receiver is switched off.
När radiomottagaren är påslagen och mottager en radiosignal avseende information som abonnenten abonnerat på avges nämnda videosignal till TV:n, varvid informationen visas på TV - skärmen. Informationen kan bestå av text och/eller bilder.When the radio receiver is switched on and receives a radio signal regarding information to which the subscriber has subscribed, said video signal is output to the TV, the information being displayed on the TV screen. The information may consist of text and / or images.
Dekodern 2 innefattar en dator med programvara för att utföra dekoderingen. Datorn innefattar även ett minne i vilket mottagen information kan lagras. Lämpligen lagras all motta- gen information, varefter abonnenten kan utvälja den informa- tion abonnenten vill se. Valet av information kan lämpligen ske genom att abonnenten har en fjärrkontroll 9 vars signaler mottages av dekodern. Härvid kan exempelvis olika typer av information ha en kod i form av ett tresiffrigt tal som abon- nenten sänder till dekodern medelst fjärrkontrollen, d.v.s. ett system av samma typ som det kommersiellt tillgängliga text-tv systemet. Man kan också tänka sig att informationen väljs medelst knappar på dekodern eller att TV:ns normala fjärrkontroll används för att sända styrsignaler avseende önskad information till TV:n. I sistnämnda fall måste det finnas en styrkabel mellan TV:n och dekodern för att överföra de av TV:n mottagna styrsignalerna till dekodern.The decoder 2 comprises a computer with software for performing the decoding. The computer also includes a memory in which received information can be stored. It is convenient to store all received information, after which the subscriber can select the information the subscriber wants to see. The selection of information can suitably take place by the subscriber having a remote control 9 whose signals are received by the decoder. In this case, for example, different types of information may have a code in the form of a three-digit number which the subscriber sends to the decoder by means of the remote control, i.e. a system of the same type as the commercially available teletext system. It is also conceivable that the information is selected by means of buttons on the decoder or that the TV's normal remote control is used to send control signals regarding the desired information to the TV. In the latter case, there must be a control cable between the TV and the decoder to transmit the control signals received by the TV to the decoder.
Det är även tänkbart att viss eller all mottagen information inte lagras i datorn utan att den visas på TV - skärmen när den mottages. Detta kan exempelvis gälla valutakursföränd- ringar.It is also possible that some or all of the received information is not stored in the computer but is displayed on the TV screen when it is received. This may, for example, apply to changes in exchange rates.
Enligt uppfinningen utsändes en eller flera tjänster i form av information, där varje tjänst som utsändes innefattar och är knuten till en kod för tjänsten ifråga. För att abonnenten skall kunna mottaga en tjänst utsändes en signal innefattande 10 15 20 25 30 35 504 237 A en identitetskod för en viss bestämd mottagare samt en tjäns- tekod för var och en av de tjänster som skall kunna mottagas.According to the invention, one or more services are transmitted in the form of information, where each service that is broadcast includes and is linked to a code for the service in question. In order for the subscriber to be able to receive a service, a signal is sent comprising an identity code for a certain specific recipient and a service code for each of the services that can be received.
Dekodern bringas att lagra nämnda tjänstekod. Vidare bringas dekodern att endast dekodera den information som tillhör en lagrad tjänstekod.The decoder is caused to store said service code. Furthermore, the decoder is caused to decode only the information belonging to a stored service code.
Varje mottagare har således en specifik identifikationskod som är lagrad i datorn. Vid mottagandet av en signal innefat- tande en identifikationskod jämföres den mottagna signalens identifikationskod med den lagrade koden. Vid överensstämmel- se mellan koderna öppnas datorns minne för inmatning av en eller flera tjänstekoder, motsvarande den eller de tjänster som abonnenten abonnerat på. Utsändande av en sådan signal riktad till en specifik mottagare sker således endast när ett eller flera tjänsteabonnemang skall upprättas eller ändras.Each receiver thus has a specific identification code which is stored in the computer. Upon receiving a signal including an identification code, the identification code of the received signal is compared with the stored code. When the codes match, the computer's memory is opened for entering one or more service codes, corresponding to the service or services to which the subscriber has subscribed. The transmission of such a signal directed to a specific receiver thus takes place only when one or more service subscriptions are to be established or changed.
När en viss information utsändes, utsänds den tjänstekod som motsvarar informationen före det att själva informationen ut- sändes. Sådan information utsändes samtidigt till en stor mängd mottagare. I stället för en specifik identifikationskod kan då en för alla eller en viss grupp av mottagare gemensam identifikationskod utsändas, vilken jämföres med en i datorn lagrad kod som medför att signalens tjänstekod mottages.When a certain information is transmitted, the service code corresponding to the information is transmitted before the information itself is transmitted. Such information was sent simultaneously to a large number of recipients. Instead of a specific identification code, an identification code common to all or a certain group of receivers can then be transmitted, which is compared with a code stored in the computer which means that the service code of the signal is received.
Vid mottagande av en signal som inte innefattar en specifik identifikationskod mottages således tjänstekoden. Härvid jän- föres den mottagna tjänstekoden med de i datorn tidigare in- lagrade tjänstekoderna för att därvid avgöra om abonnenten abonnerat på ifrågavarande tjänst. Om så är fallet dekoderas informationen. Om så inte är fallet dekoderas inte informa- tionen.Thus, when receiving a signal that does not include a specific identification code, the service code is received. In this case, the received service code is compared with the service codes previously stored in the computer in order to determine whether the subscriber has subscribed to the service in question. If so, the information is decoded. If this is not the case, the information is not decoded.
Den för föreliggande förfarande nödvändiga hårdvaran och mjukvaran kan lätt sammanställas och utföras av fackmannen, varför de inte närmare beskrives här.The hardware and software required for the present process can be readily assembled and performed by those skilled in the art, so they are not described in detail here.
Ovan nämndes att i stället för en specifik identifikationskod 10 15 20 25 30 35 504 237 ä kan en för en viss grupp av mottagare gemensam identifika- tionskod utsändas. Enligt ett föredraget utförande bringas en kod avseende ett visst geografiskt område att utsändas i sam- band med att en tjänstekod utsändes. Detta medför att en viss information, såsom en lokalt betingad information, exempelvis en lokal väderrapport, kan riktas till abonnenter inom det lokala området.It was mentioned above that instead of a specific identification code 10 15 20 25 30 35 504 237 ä, an identification code common to a certain group of recipients can be sent. According to a preferred embodiment, a code relating to a certain geographical area is caused to be transmitted in connection with the transmission of a service code. This means that certain information, such as a locally conditioned information, for example a local weather report, can be directed to subscribers within the local area.
Enligt en föredragen utföringsform utgöres nämnda kod avseen- de geografiskt område av områdets postnummer eller del därav.According to a preferred embodiment, said code regarding geographical area consists of the area's postal code or part thereof.
Med del därav menas att exempelvis ett femsiffrigt postnummer avser ett visst område, medan de tre första siffrorna är ge- mensamma för nämnda område samt ett antal angränsande områ- den. Således kan exempelvis en kod 181 OO avse alla områden, vars postnummer börjar på 181.Part of this means that, for example, a five-digit postal code refers to a certain area, while the first three digits are common to the said area and a number of adjacent areas. Thus, for example, a code 181 OO may refer to all areas, whose zip code begins at 181.
En signal som utsändes kan således först innefatta en identi- fikationskod av specifik eller allmän karaktär, sedan en tjänstekod följd av en kod avseende ett visst geografiskt område och slutligen själva informationen.A signal transmitted may thus first comprise an identification code of a specific or general nature, then a service code followed by a code relating to a certain geographical area and finally the information itself.
Det är föredraget att före identifikationskoden utsända en s.k. RIC - signal (Radio Identification Code) vilken öppnar mottagaren till att mottaga följande del av signalen och vilken signal innefattar en tidssignal. Härigenom får således dekodern uppgift om aktuellt datum och klockslag. Denna information används för att styra den tid under vilken ett visst abonnemang skall gälla.It is preferred to send before the identification code a so-called RIC signal (Radio Identification Code) which opens the receiver to receive the following part of the signal and which signal includes a time signal. This gives the decoder information about the current date and time. This information is used to control the time during which a particular subscription is to be valid.
Dekodern bringas således att mottaga en tidssignal. Enligt ett utförande överföres till dekodern uppgift om den tidspe- riod, under vilken abonnemanget på den ifrågavarande tjänsten skall gälla i samband med att nämnda identitetskod och tjäns- tekod utsändes. Tidsperioden lagras i datorns minne. När tidsperioden utgått bringas dekodern inte längre att dekodera information för vilken abonnemanget upphört. Detta kan lämp- ligen ske genom att ifrågavarande tjänstekod utraderas i da- 10 15 20 25 30 504 237 lm torns minne.The decoder is thus caused to receive a time signal. According to one embodiment, information is transmitted to the decoder about the time period during which the subscription to the service in question shall apply in connection with the said identity code and service code being transmitted. The time period is stored in the computer's memory. When the time period has expired, the decoder is no longer caused to decode information for which the subscription has ended. This can conveniently be done by deleting the service code in question in the memory of the tower.
Enligt ett alternativt utförande utsändes nämnda identitets- kod och tjänstekod periodiskt med visst tidsintervall, där dekodern endast bringas att dekodera mottagen information avseende nämnda tjänstekod under en tid som motsvarar nämnda tidsintervall. Tidsintervallet kan exempelvis vara fem minu- ter. I detta utförande uppdateras således vilka abonnemang som är aktuella var femte minut. Tidsintervallet kan givetvis vara längre, exempelvis ett dygn.According to an alternative embodiment, said identity code and service code are transmitted periodically with a certain time interval, where the decoder is only caused to decode received information regarding said service code for a time corresponding to said time interval. The time interval can be, for example, five minutes. In this embodiment, the subscriptions that are relevant are thus updated every five minutes. The time interval can of course be longer, for example one day.
Genom uppfinningen kan således olika informationer utsändas rikstäckande över exempelvis det existerande mini-call nätet.Through the invention, various information can thus be transmitted nationwide over, for example, the existing mini-call network.
Trots en rikstäckande utsändning kan varje enskild mottagare programmeras, på ovan angivet sätt genom utsändning på nätet, att dekodera viss del av informationen genom att utsända dess identifikationskod och uppgift om tjänstekod eller tjänsteko- der. Dessutom kan information styras till att kunna mottagas i ett visst geografiskt område genom utsändande av nämnda kod för detta ändamål.Despite a nationwide broadcast, each individual recipient can be programmed, in the manner indicated above by broadcasting on the Internet, to decode a certain part of the information by transmitting its identification code and information on service code or service codes. In addition, information can be controlled to be able to be received in a certain geographical area by transmitting said code for this purpose.
Ovan har ett antal utföringsformer beskrivits. Emellertid kan uppfinningen modifieras. Exempelvis behöver inte all informa- tion utsändas rikstäckande. Vidare kan flera koder än de ovan angivna för andra ändamål utsändas. Exempelvis kan ett s.k. password utsändas vilket måste överensstämma med ett i datorn av abonnenten inmatat password för att mottagaren skall deko- dera mottagen information som omfattas av abonnemanget.A number of embodiments have been described above. However, the invention can be modified. For example, not all information needs to be sent nationwide. Furthermore, more codes than those listed above can be transmitted for other purposes. For example, a so-called password is transmitted, which must correspond to a password entered into the computer by the subscriber in order for the recipient to decode received information covered by the subscription.
Föreliggande uppfinning skall således inte anses begränsad till de ovan angivna utföringsformerna, utan kan varieras inom dess av bifogade patentkrav angivna ram.Thus, the present invention is not to be construed as limited to the above embodiments, but may be varied within the scope of the appended claims.
