I thought HDMI was encrypted to prevent this sort of thing? If you can do this with an FPGA what stops you from designing one that will copy a Blu ray?

- white-flame 12y agoNo, HDMI offers encryption, called HDCP. Note that HDCP also existed on DVI before HDMI rolled around. The article specifically notes that he skipped HDCP support among other features.
- mikeash 12y agoAnd just to clarify, "offers encryption" means it's optional. The sender can require HDCP if it wishes, but it can also transmit plain unencrypted data. Some devices will work either way, but restrict what they do without HDCP. (For example, iTunes on a Mac won't play DRM'd videos if a non-HDCP connection is present.) Presumably whatever this guy is using for his video source doesn't require HDCP.
- fragmede 12y agoIt's just easier to rip a Bluray in software. Playing back a Bluray and ripping the video is probably going to be real time, while Bluray's will rip faster than that.
