my project is as follow
i will have a video on a CD the video will be encrypted by a program on my pc that will switch some bytes of the video
what i want is to reprogram a TV/DVD Player so if i put the CD on it the TV/DVD Player will take the video from the CD and Decrypt the video by putting the bytes of the video back to there original place then play it to the TV .
that was all i need to have
Note : .
The DVD Player can be done by :
--Reprogramming an existing one
--Build one using Arduino and a DVD Player from PC
--Build a built in electronic box to do the Decryption
