DVD Stream Recording shall be used for realtime recording and playback of given packetized bitstreams. The data of the bitstream are organized into Stream Object Units, which in turn consists of stream packs (O_S_P) with a stream pack header (P_H) followed by a stream packet (S_PES_P), wherein a stream packet (S_PES_P) contains further header data (PES_H, S_ID, A_H) and an Application Packet Area (A_P_A), which is filled with a sequence of Application Packets each prefixed by an Application Time Stamp (ATS). In case of very low bitrate stream recording empty packets are recorded, which are marked as stuffing packets. This ensures that every Stream Object Unit - even in areas where stuffing is performed - contains at least one Application Time Stamp value.
