public class FrameBodyPOSS
extends AbstractID3v2FrameBody

4.21.   Position synchronisation frame

   This frame delivers information to the listener of how far into the
   audio stream he picked up; in effect, it states the time offset from
   the first frame in the stream. The frame layout is:

     <Head for 'Position synchronisation', ID: "POSS">

     Time stamp format         $xx
     Position                  $xx (xx ...)

   Where time stamp format is:

     $01  Absolute time, 32 bit sized, using MPEG frames as unit
     $02  Absolute time, 32 bit sized, using milliseconds as unit

   and position is where in the audio the listener starts to receive,
   i.e. the beginning of the next frame. If this frame is used in the

   beginning of a file the value is always 0. There may only be one
   "POSS" frame in each tag.
