Abstract
A bejelentés egy információhordozóra vonatkozik, mely tartalmazfutáshossz-korlátozó jeleket egy nyomvonalon, a jelek futáshosszaiképviselik az elsődleges csatorna biteket (3) és a jel továbbiparaméterének változásai képviselik a másodlagos csatorna biteket (5).Csak a legalább előre meghatározott futáshosszal rendelkező jelekrendelkeznek az említett variációkkal. A bejelentés továbbákódolóberendezésre vonatkozik, mely tartalmaz konvertáló eszközt abináris forráskód csatornajellé való konvertálására, a csatornajeltartalmaz egy elsődleges csatornajelet, mely az elsődleges csatornabiteket (3) képviseli és egy másodlagos csatornajelet, mely amásodlagos csatorna biteket (5) képviseli. A konvertáló eszközt úgyhelyezik el, hogy detektálja az elsődleges csatorna bitek (3)futáshosszát. A konvertáló eszköz tartalmaz még beillesztő eszközt amásodlagos csatornajel generálására, melyet csak akkor végez el, haegy előre meghatározott minimális futáshosszal rendelkező futáshossztdetektál. A bejelentés egy kódoló eljárásra is vonatkozik, melytartalmazza a bináris forráskód csatornajellé történő konvertálását. Acsatornajel tartalmaz egy elsődleges csatornajelet, mely az elsődlegescsatorna biteket képviseli, és egy másodlagos csatornajelet, mely amásodlagos csatorna biteket képviseli. Az eljárás további része azelsődleges csatorna bitek futáshosszának detektálása és az eljárástovábbi része még a másodlagos csatornajelek generálásának lépése csakabban az esetben, ha egy előre meghatározott minimális futáshossztdetektál. A bejelentés még egy dekódoló berendezésre vonatkozik, melytartalmaz dekódoló eszközt egy csatornajel bináris kóddá történődekódolására. Ó
