But I am dealing with piped traffic so STDIN will be the input and lines should be written one by one

STDIN and STDOUT are filehandles, like $ifh and $ofh in my code. Here, I'm using select to get STDOUT and ARGV to get Perl's magic command-line argument filehandle, which reads from STDIN when no files are specified on the command line. I've assumed you don't want some of the binary data from here, but note that this still doesn't strip all of it out.

use warnings;
use strict;
use Text::CSV; # also install Text::CSV_XS for speed

my $csv = Text::CSV->new({ binary=>1, auto_diag=>2, escape_char=>'\\',
    eol=>$/, quote_char=>'"', sep_char=>";", always_quote=>1 });
while ( my $row = $csv->getline(*ARGV) ) {
    $row->[5] = pack '(H2)*', split /:/, $row->[5];
    $row->[5] =~ s/\A\x19\x68\x09\x24\x00+|\x00+\z//g;
    $csv->print(select, $row);
}
$csv->eof or $csv->error_diag;
