METHOD AND DATA RECORDER FOR CONVERTING FIRST DATA PACKET TIMESTAMPS BASED ON A FIRST CLOCK RATE TO SECOND DATA PACKET TIMESTAMPS BASED ON A SECOND CLOCK RATE

摘要

DVD Rewritable / Re-recordable disc recording of MPEG data packets, for example, a digital bit stream and playback will be used. To enable proper real-time playback of stored MPEG transport packets, time information is added to every data packet to be recorded. The DVD streamer is, for example, connect to the application device through an IEEE 1394 interface. The interface uses a time stamp (timestamp) having a special internal format. According to the present invention, the time stamp is generated by this interface also generates additional independent streamer-DVD is used for recording on the streamer to the specific time stamps. However, since the DVD Streamer timestamp format is different, and IEEE 1394 timestamp format, timestamp format conversion is performed. For this timestamp format conversion, the difference between consecutive IEEE 1394 timestamps are determined and used for calculating the DVD stream recording timestamps.
