Based on a few assumptions on the structure of your input file, like
- the numerical "detection type" is introduced by the string cn2=, up to four digits, and terminated by a space char.
- there's no more than one time stamp per line, introduced by the partial string rt=, 10 digits long

here's an awk proposal, working on a mock up input file, that might satisfy your request:

Code:

awk '
BEGIN                   {HRago = srand() - 3600                                                                                 # srand is seeded from the clock, and returns that value
                         for (DMX = n = split ("0 16 272 512 768 2048 2304 1024 1280", DETTYPE); n; n--) CNT[DETTYPE[n]] = 0;   # det. type, and counter (indexed by det type) arrays
                         TIMPAT = "rt=[0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9]"                                       # define epoch time pattern with introducing string
                        }
match ($0, TIMPAT)      {if ((substr($0, RSTART+3, 10) > HRago                  ) &&                                            # epoch time greater than one hour ago AND
                             (match ($0, /cn2=[0-9]* /)                         ) &&                                            # det.type introducer found AND
                             ((DT = substr($0, RSTART+4, RLENGTH-5)) in CNT     )       ) CNT[DT]++                             # det type known in counter array --> incr. counter
                        }
END                     {for (i=1; i<=DMX; i++) print "Detection type:", DETTYPE[i], ", count:", CNT[DETTYPE[i]]                # output detection types and counters
                        }
' file
Detection type: 0 , count: 1
Detection type: 16 , count: 0
Detection type: 272 , count: 0
Detection type: 512 , count: 1
Detection type: 768 , count: 1
Detection type: 2048 , count: 0
Detection type: 2304 , count: 0
Detection type: 1024 , count: 0
Detection type: 1280 , count: 0

vdltodmx

vdltodmx(1)						      General Commands Manual						       vdltodmx(1)

NAME

       vdltodmx - dmx configuration file parser and printer

SYNOPSIS

       vdltodmx infile outfile

DESCRIPTION

       vdltodmx  reads	the  input file, which should be in VDL configuration file format.  After a successful parse, a file in Xdmx configuration
       file format is written to the output file.

       The VDL file format is used with xmovie, which is available from http://www.llnl.gov/icc/lc/img/xmovie/xmovie.html

EXAMPLE

       Given the following VDL-format file:
	      0
	      2
	      #
	      #
	      2560 2048 Left two-thirds [restrict=*:2]
	      2
	      :2.1 1280 2048   0    0 0 0
	      :2.2 1280 2048   1280 0 0 0
	      4
	      1280 1024 0      0
	      1280 1024 0      1024
	      1280 1024 1280   0
	      1280 1024 1280   1024
	      #
	      2560 2048 Right two-thirds [restrict=*:2]
	      2
	      :2.2 1280 2048   0   0 0 0
	      :2.3 1280 2048   1280 0 0 0
	      4
	      1280 1024 1280	0
	      1280 1024 1280	1024
	      1280 1024 2560 0
	      1280 1024 2560 1024
       the following DMX-format file will be produced:
	      #
	      #
	      virtual "Left two-thirds" 2560x2048 {
		  display :2.1 1280x2048;
		  display :2.2 1280x2048 @1280x0;
	      }
	      #
	      virtual "Right two-thirds" 2560x2048 {
		  display :2.2 1280x2048;
		  display :2.3 1280x2048 @1280x0;
	      }

BUGS

       If the VDL file is not in the expected format, the program will probably dump core.
