Abstract
A találmány tárgya berendezés és eljárás MPEG-2adatfolyam SMPTE-259 kompatibilis adatfolyammá történő átalakítására.A találmány szerinti eljárás lényege, hogy meghatározzák a bejövőMPEG-2 bitsorozat bitsebességét; dekódolják a bejövő MPEG-2bitsorozatot; újra kódolják a dekódolt MPEG-2 bitsorozatot olyanbitsorozattá, amely csak I-kereteket tartalmaz; szelektív módonfigyelmen kívül hagyják a csak I-keretekből álló bitfolyam minden1001-edik újra kódolt I-keretét; szelektív módon figyelmen kívülhagyják a csak I-keretekből álló bitfolyam minden 1001-edik újrakódolt I-keretében lévő pixelinformációt; és a megmaradó, újra kódoltI-kereteket kódolással átalakítják SMPTE-259 bitsorozattá. A találmányszerinti eljárás egy másik változatának lényege, hogy kinyerik azMPEG-2 adatokat a bejövő MPEG-2 kompatibilis bitsorozatból; kinyerik avideo paramétereket az MPEG-2 adatokból; kinyerik a kódolásiparamétereket az MPEG-2 adatokból; dekódolják az MPEG-2 adatokatalkotó, változó szóhosszúságú dekódolt adatokat; pixelinformációtállítanak elő a változó szóhosszúsággal kódolt adatok alapján;kódolással átalakítják az előállított pixelinformációt csak I-kereteket tartalmazó bitsorozattá; szelektív módon figyelmen kívülhagyva minden 1001-edik kódolt I-keretet; és kódolással átalakítják akódolt I-kereteket SMPTE-259 kompatibilis bitsorozattá. A találmányszerinti berendezésnek a következő részegységei vannak: a bejövő MPEG-2 bitsorozat bitsebességét meghatározó MPEG-2 dekódoló (50); az MPEG-2dekódolóval (50) összeköttetésben álló, a bejövő MPEG-2 bitsorozatotdekódoló, változó szóhosszúságú dekódoló (51); az MPEG-2 dekódolóval(50) és a változó szóhosszúságú dekódolóval (51) összeköttetésbenálló, a dekódolt bitsorozatot kódolással csak I-kereteket tartalmazóbitsorozattá alakító kódkonverter (56); az MPEG-2 dekódolóval (50), aváltozó szóhosszúságú dekódolóval (51) és a kódkonverterrel (56)összeköttetésben álló kereteldobó egység, amely szelektív módonfigyelmen kívül hagy meghatározott sorszámú kódolt I-kereteket vagymeghatározott sorszámú kódolt I-keretekben lévő pixelinformációt, ésezáltal módosított bitsorozatot állít elő; és a kódkonverterrel (56)összeköttetésben álló, a módosított bitsorozatot kódolással MPTE-259kompatibilis bitsorozattá alakító SMPTE-259 kódoló (64).
