CA 2167125
A data multiplexer for multiplexing at least digital moving picture data and pattern data (character data) comprises a packetizing means for forming the digital moving picture data and the pattern data into PES packets of a predetermined format based on the MPEG-2 standard, each packet consisting of a header and an actual data region; an adding means for adding, to the header of each packet, a flag to identify the moving picture data and the pattern data; and a means for multiplexing the packets. An ID flag recorded in the header of each PES packet serves to identify a video packet, an audio packet or a pattern data packet. Each packet of the pattern data and the digital moving picture data includes a time stamp indicative of decode or display timing. In this data multiplexer, the pattern data (character data) on any horizontal scanning line can be multiplexed and recorded with the digital moving picture data.
