Abstract

A találmány tárgya eljárás egy továbbított adatáram több szekciójánakeltárolására, amelynek során az adatáramot veszik; az adatárambóllegalább egy szekció jellemzőnek megfelelően a szekciók közül egyszekciót kiszűrnek; a kiszűrt szekciót eltárolják; és az utóbbi kétlépést ismételve a már kiszűrt és eltárolt szekcióhoz kapcsolódó vettszekciók közül előre meghatározott számú, a legalább egyszekciójellemzőt tartalmazó szekciót eltárolnak. A találmány tárgyatovábbá eljárás egy adatáramban ciklikusan továbbított, legalább egyközös szekció jellemzővel rendelkező szekciókból álló és egy elsőszekciót és egy utolsó szekciót tartalmazó csoport tárolására,amelynek során az adatáramot veszik; az első szekciót letöltik, és egymemóriában eltárolják; ezt követően a szekciócsoport egymást követőszekcióit egymás után, közvetlenül az első szekció letöltését követőenletöltik, és egy-egy memóriahelyen egymás után eltárolják, amíg vagyegy előre meghatározott számú szekciót el nem tároltak a memóriában,vagy pedig az előre meghatározott számú szekció eltárolása előtt azutolsó szekciót is el nem tárolták, vagy amíg előre meghatározottszámú szekciót el nem tároltak, amelynek során az egyesmemóriahelyeken tárolt szekciókat a csoport egymást követően letöltöttszekcióival egészen az utolsó szekció eltárolásáig felülírják. Atalálmány tárgyát képezik a fenti eljárásokat megvalósítóberendezések, valamint a javasolt eljárás és a berendezés alkalmazásaa szekciókon kívül video és audio televízióadatot is tartalmazó MPEGbitfolyam formájú adatáramhoz.
