Pro:Idiom not running on samsung Tizen 3.0

Question

I am trying to run the Pro:Idiom video using the udp URL, but it's not getting decrypted. My Samsung Tv is using Tizen OS version 3.0 and here is the code below:

try{
  var drmParam = new Object();
  drmParam.ForensicData = "abcvdfdsfsadfasdfafda";
  webapis.avplay.setDrm("PROIDIOM", "Initialize", JSON.stringify(drmParam));
  webapis.avplay.open("udp://238.255.4.3:5000");
  webapis.avplay.setDisplayRect(0, 0, 1920, 1080);
  webapis.avplay.prepare();
  webapis.avplay.play();
} catch (err) {
  console.log(err);
}

Also, I am not sure about the forensic data, how to get it ?
