Just a quick bunch of files i used to test how quickly a PIN from Netflix can be aquired using the Netflix-App on a standard E/F/H - Series Television.

Motivation

The Netflix App does currently not rate-limit the retries upon entering a wrong parental-pin, so as an educational project i developed a simple remote using an arduino which can be controlled via a PC. Maybe someone finds parts of this project useful for a very different application.

Arduino Remote

First off, you have to build a remote. This is not very complicated, you just need these components:

  • current Arduino IDE with the Library IRremote - can be typically installed via Library Manager
  • almost any Arduino with an USB-Port will do, i used an Arduino Micro
  • an IR-Diode, i bought a 5mm 940nm Diode from ebay (for less than a Buck), if you have an old remote, you can also use that
  • A Resistor, so the Diode does not draw too much Ampere from the Arduino Pin. You check the schematics, but typically, something beetween 50-150 Ohms will do
  • optionally a breadboard, so you can quickly assemble the remote.

Assembly

  1. Connect the Resistor to Pin 3 (sometimes called D3) on your Arduino
  2. Connect the anode (long leg) of the Diode to the other end of the Resistor
  3. Connect the catode (short leg) of the Diode to any GND Pin of your Arduino

Testing

  1. Turn on your TV
  2. Connect your Arduino to your PC and upload SamsungTVPin.ino via the Arduino IDE to your Arduino
  3. Point your assembly towards the TV, as close as possbile as the range can be limited
  4. Open the Serial Monitor and set it to 9600 Baud
  5. Send the command 1 via the Serial Monitor, the Volume of the TV should increase

Congratulations, you have a working Remote which is controllable via your PC!

PC-Controller

Needed components:

  • current Processing IDE with the Libraries Serial and Video - can be typically installed via Library Manager
  • a Webcam, ideally with a long cable

Setup

  1. Turn on your TV
  2. Start the Netflix-App and select a Profile
  3. Select a movie where the Pin is requested
  4. Point your selfmade-remote towards the TV, as close as possible
  5. Connect your Arduino to your PC
  6. Connect your Webcam to your PC and point it towards the TV
  7. Run either ProcessingNetflixPINDate.pde (for quickly going through Pins with the format DDYY) or ProcessingNetflixPIN.pde (for full bruteforce)

The Processing-Apps will try each available combination and save a picture taken from the webcam. The filename will always include the corresponding Pin that was used for that try. That way you can let the program do its job and later on check on the pictures which Pin was successful.

Want to improve on that? Just go ahead and implement something like an automatic detection via webcam if the Pin was correct and stop the program :-)

Adding more Remote-Commands

Currently there are only a few commands available:

  • POWER
  • INFO
  • FACTORY
  • THREESPEED
  • VOLUP
  • VOLDOWN
  • ENTER
  • CURSORUP
  • CURSORDOWN
  • CURSORRIGHT
  • CURSORLEFT

Most probably, there is a very easy way to add more commands, or they might be already available in the IRRemote Lib, i never checked. Or you can record the code you are looking for with an IR-Receiver, with the same tools you used above. It is up to you.

This is how i did it:

  • Search around the Web for something like Samsung TV hex codes
  • You will surely find some page or file with a list of Hex Codes for the function you are trying to implement
  • You need only a part of each hex-code
  • First remove the lead-in which should be 0000 006D 0000 0022 00AC 00AB
  • Then remove the lead-out which should be 0015 0689
  • Now replace every 0015 0041 with a 1
  • Then replace every 0015 0016 with a 0
  • If needed, remove all spaces and use a hex-converter on the ones and zeros

Voilà, you have your code for the remote. Prepend a simple 0x and use it in the arduino sketch.
