ABSTRACT:
A method for determining the address of a frame inside a data sector of an optical recording medium (17), the sector comprising a plurality of frames, each frame being preceded by a synchronization code, and an apparatus (10) for reading from and/or writing to optical recording media (17) using such method.A method for determining the address of a frame inside a data sector of an optical recording medium (17) that is robust against streaming loss is proposed. The method comprises the steps of:keeping a history of previously detected synchronization codes;appending (2) the detected synchronization code to the history;comparing (3) a pattern of the last synchronisation codes with a plurality of valid patterns of synchronization codes;delivering (4) a valid frame address if the pattern corresponds to a valid pattern, the frame address corresponding to the valid pattern, anddelivering (7) an error frame address if the pattern does not correspond to a valid pattern.
