In fact, it's only hurtful to the end user. Encrypting the compressed video on disc is one thing (a much more sensible thing), but encrypting raw digital video at 1920x1080 is meaningless. Nobody will copy raw video like this. A 90 minute movie (assuming 24p no audio) would consume just under a terrabyte and would require a storage transfer rate of 150 megabytes per second. (Not only that but the decode/reencode process will lower image quality) How is it hurtful? Signal errors mean a whole frame gets lost, not just a pixel - and saying someone shouldnt be able to play a movie they paid for on a computer monitor is just nuts. Plus you could argue that the needless encrypt/decrypt processing wastes valuable energy ;) HDCP is utterly pointless. In fact, it’s only hurtful to the end user.
