- values use plain ASCII text numbers
- general terms: integer = signed value
- general values: byte/char/octet = one char value ; short/word = two char values ;
long = four char values
FILE INFO
Suffixes = ".mov", ".qt" ; Mac OS Type = "MooV" ; Mac OS Creator = "TVOD" ;
MIME="video/quicktime"
Standard single fork ASCII text file that is used for server-side scripts
to generate QT related text files on the fly or when a specific MIME is not
registered on a host server.
QUICKTIME 4 ATOM HACK STRUCTURE
-> 1-4 bytes media type = byte to long ASCII uppercase text string
- current types are Plain QT-styled text = 'TEXT' ; W3C SMIL = 'SMIL'
- current types are RTSP link = 'RTSP' ; RFC SDP live session = 'SDP'
-> 1-4 bytes media handler = byte to long ASCII text lowercase string
- current type is Text Media Handler = 'text'
-> 1 byte text separator = byte ASCII text character
(eg. space or LF and/or CR)
-> above specified data structure
