Time code description is in two modes, integer or digit mode. integer mode allows easy mathematical manipulation (using c++ operators). digit mode allows the user to manipulate the time code digit by digit. more specifically, time code is made of a data window (array) for media data content. if the multimedia content is audio (1d stream) then a type ii filter is implemented for this stream. it also has time based indexes. namely :
b : beginning - the absolute first time
s : start - the start time
c : current - the current time
e : end - the last time
f : finish - the absolute last time
for all instances :
i] b<=s<=eii] s<=c
