Abstract
A stream conversion apparatus receives an MPEG2 transport stream as an input stream . To each packet contained in this stream, a time stamp assignment section assigns the input time of that packet as a time stamp. A packet reduction section deletes NULL packets which appear in the stream with a predetermined repetition pattern. Based on a proportions of the NULL packet in the stream, a time stamp replacement section replaces the time stamp assigned to the packets which have not been deleted by the packet reduction section . The packets which have under gone the selective time stamp replacement are temporarily stored in the buffer , and outputted by the packet reading section and the output section , such that each packet is outputted at a time indicated by the time stamp assigned to that packet.
