Optionally following the pack header, there can be a ''[system header|http://www.mpucoder.com/DVD/sys_hdr.html]''. This specifies such things as how many audio and video streams there are, how much bandwidth they might need, and whether audio and video are in fact synchronized to the system clock. The first pack in the file must have a system header. This can be repeated at intervals throughout the file, but it must always have the same contents.
Note that, apart from the requirement for the presence of a system header, there is no special header at the start of an MPEG file/bytestream. This means it is in principle possible to concatenate two or more MPEG files together to achieve a playable result, provided that 1) there are no leftover bytes after the end of the last packet in each file, and 2) the player can cope with any resultant discontinuities in the progression of the PTS.
