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 been recorded, the control data in the control file being intended for controllin g the reproduction of representations of the main data in the main data file during or after read-out of the main data file. The ma in data file and the control file are derived from a main data signal and a control data signal respectively in accordance with the sa me formatting and coding rules. The control data sig- nal comprises packets (151) of n identical control data bit groups (150), n being an integer greater than or equal to 2. Moreover, a method and device for recording the control and main data are described. In addition, a device for reading the record carrier is disclosed.
