Abstract

Datamaskindata tilveiebrakt i samsvar med en første dataprotokoll, slik som Intemet- protokoll, kommuniseres over et TV-kringkastingsnettverk ved anvendelse av en andre dataprotokoll slik som MPEG2. Datamaskindata i den første dataprotokollen blir innkapslet i det minste i en datastrøm for fordeling i samsvar med den andre dataprotokollen. I det minste den ene datastrømmen som innkapsler datamaskindata multiplekses med en flerhet av datastrømmer som passer med den andre dataprotokollen for transmisjon av nettverket, som kan være en kabel eller satellitt-TV-nettverk. Datastrøminnkapslingen av datamaskindata mottas fra nettverket i samsvar med den andre dataprotokollen og behandles i samsvar med den andre dataprotokollen for å gjenvinne datamaskindata i den første dataprotokollen. Et prioriteringsskjema tilveiebringes hvor forskjellige meninger i den første dataprotokoll prioriteres i utgangsmultipleksene i samsvar med i det minste en kildeadresse, bestemmelseadresse, datatype og forbindelsestype.
