---------------------
This is actually just a minor variation defined in IEC-62107 on the
Super Video CD 1.0 format for _compatibility with current products in
the market_. It differs from the Super Video CD 1.0 format in the
following items:
* The system profile tag field in '/SVCD/INFO.SVD' is set to '1'
instead of '0'.
* The system identification field value in '/SVCD/INFO.SVD' is set to
'HQ-VCD' instead of 'SUPERVCD'.
* '/EXT/SCANDATA.DAT' is mandatory instead of being optional.
* '/SVCD/SEARCH.DAT' is optional instead of being mandatory.
