RECORD CARRIER ON WHICH A MAIN DATA FILE AND A CONTROL FILE HAVE BEEN RECORDED, METHOD OF AND DEVICE FOR RECORDING THE MAIN DATA FILE AND THE CONTROL FILE, AND DEVICE FOR READING THE RECORD CARRIER

摘要

A record carrier (184) is described on which main data files (TV/4,TV,...,256TV) and a control file (BB; IIDB) have beenrecorded, the control data in the control file being intended for controllingthe reproduction of representations of the main datain the main data file during or after read-out of the main data file. The maindata file and the control file are derived from a maindata signal and a control data signal respectively in accordance with the sameformatting and coding rules. The control data sig-nal comprises packets (151) of n identical control data bit groups (150), nbeing an integer greater than or equal to 2. Moreover, amethod and device for recording the control and main data are described. Inaddition, a device for reading the record carrier isdisclosed.
