Abstract

An optical disc recording apparatus includes an information receiving module, a commercial detecting module, an information processing module, a play parameter generating module and a write-in module. The commercial detecting module detects the start and end points of each commercial section in the real-time information received, and the information processing module transforms the real-time information into a data structure conforming to a standard recording format, meanwhile creating control information according to the recording format. The data structure includes a plurality of sublevels, and the identification number of each sublevel is adjusted according to the start and end points of each commercial section so that the start and end points of one commercial section are exactly the start and end points of one sublevel. The play parameter generating module generates play parameters conforming to the standard recording format.
