Abstract

Atalálmány tárgya egyrészt egy vevő- és dekódolóberendezés digitálistelevízió-rendszerhez, amelynek tömörített MPEG típusú jelet vevőeszköze, a vett jelet egy televíziójel előállításához dekódolóeszköze, a televíziójelet egy televíziókészülékhez továbbító eszköze,felhasználói bemenet interfésze, továbbá a vevő- ésdekódolóberendezést a bemeneti felhasználói interfészen keresztülfogadott bemeneti jeleknek megfelelően vezérlő, több porttól jeleketfogadó és azok részére adatot előkészítő eszközkezelő eszközöketmagában foglaló számítógéprendszere, valamint az eszközkezelőeszközhöz kapcsolódó, az eszközkezelő eszköztől érkezett adatotfeldolgozó és annak részére adatot visszajuttató eszközt magábanfoglaló virtuálisgép-eszköze van. Atalálmány tárgyát képezi továbbáegy vevő- és dekódolóberendezés sugárzott jelek vételére, amely avevő- és dekódolóberendezést a vett jeleknek megfelelően vezérlő, többporttól jeleket fogadó és azok számára adatot előállító eszközzel,valamint a vevőeszköztől vett adatot feldolgozó és annak részéreadatot visszaküldő virtuálisgép-eszközzel rendelkező vezérlőeszközttartalmaz. Ajavasolt vevő- és dekódolóberendezéseket tartalmazórendszerben a különböző vevő- és dekódolóberendezések egyetlen közösvirtuálisgép-eszközzel, valamint különböző áramkörökhöz kapcsolódó,különböző eszközkezelő eszközökkel rendelkeznek.
