Curious about this article I went on a short research trip down content protection lane. Now, if I understand correctly, high-definition media is re-encrypted at each link in the chain from origin to display device (let's not mislabel this as "end-to-end encryption"), which is why HDCP has to be as much a legal construct as it is an engineering one (and broken in both domains).
Since unlicensed HDCP strippers (basically counter-encryption devices that take encrypted HDMI in and talk unencumbered HDMI out) can be ordered straight off Alibaba, I don't see how this processor is any further impediment to the systematic bootleggers of high-definition content and its redistribution in alternative forms.
I concluded that the practical application is therefore limited to impeding the casual viewer from cloning original media files or streams.
What it further provides is another sterling opportunity for interoperability failure between devices.
- MichaelGG 13y agoHow do "casual viewers" clone media streams anyways? They aren't so casual at that point. Whatever hacks a casual viewer needs in order to copy a stream, they could just as easily download a DRM-stripped one. So, on the surface, it does not seem like this helps anything at all. The only effect of HDCP I've ever seen is sometimes AppleTV can't stream Netflix because of an HDCP error.
