InstaPort chips decrypt HDCP, Can this be used to access full bandwidth DVD-A PCM?
This guy: http://sites.google.com/site/hdcontentsecurity/ has discovered that TVs, AV receivers, etc featuring Silicon Image InstaPort HDMI switch chips strip / decrypt HDCP encryption information from HDMI.
You can grab the decrypted signals with a relatively simple process of soldering a HDMI cable onto the signal lines coming out of the Silicon Image InstaPort switch chip. I was wondering if the same applies to the audio data on a HDCP HDMI signal? DVD-Audio allows full sample rate / sample depth to be transmitted over HDCP encryption supported devices without the downsampling to 48K 16-bit as seen on standard SPDIF output. If this applies to the audio data this could be a much simpler way of gaining access to the full sample rate / sample depth digital DVD-Audio data. HDMI capture cards are quickly lowering in cost too. Cheers! |
