Data stream contents

The data stream is formatted as a sequence of packs in one of the forms described above. When data streams are used with sequential access media, they may have the same name as the map packet DSI. Because DDVID uses this data as a stream of bytes, the sector size, record size and blocking factor on the input media are irrelevant.
