– The FIC-XTractor window with its three views to the FIC content
The FIC-XTractor is a powerful, yet easy to use tool for everybody who wants to dig into the
content of the Fast Information Channel (FIC). Similar to a protocol analyser, the tool parses
the FIC on bit stream level. The FIC-XTractor reads the FIC from a file or from the contents
of the time-shift buffer. Then it decodes the FIC and displays the results according either to
their chronological order frame by frame or to their FIG type and extension.
A chosen FIG will be presented in a tree-like view where the FIG, according to the DAB
standard, will be resolved into its elements. Moreover, the binary patterns of these elements
will be translated into a form readable by men; this may be a text string, a date as in FIG
0/10, a frequency as in FIG 0/21, or geographic coordinates as in FIG 0/22.
The
FIB Hex
panel displays the FIB in hexadecimal form. The analysed FIG will be marked
within the FIB with a grey background. Small icons within the frame list or FIG list flag
erroneous FIGs, FIBs with CRC errors, and multiplex reconfigurations.
