No, the NeTV does NOT do any kind of decryption. What it does do is encrypt its own image using the same key in parallel, so that it can overlay its own display on top of the incoming display stream.
It does include an implementatiom of HDCP that could be used for decryptioon if you work hard enough at it (and I would guess someone worked hard enough at it), but as it comes out of the box, NeTV cannot be used to strip off HDCP.
- lelandbatey 12y agoIs there anything that does decrypt HDCP in real time? Something where you plug an encrypted cable into one end and it outputs an unencrypted source on the other? One that maintains things like audio?
- 1offi 12y agoSure: all SiI9187 based HDMI splitters do, e.g. amazon.com/dp/B005HXFARS
- jrockway 12y agoThe amazon pages say they don't decrypt anymore. That's a fragile attack anyway, as I imagine the key they're using would be revoked. The only attack that works is one that uses the master key to generate keys that haven't been revoked, which I doubt their hardware does. (Illegal and all that. Just being an HDCP endpoint is easy; take the chips from your TV product and stick them in the splitter. "Oops, sorry." But then you get revoked.)
