High-bandwidth Digital Content Protection?

Quote HDMI, DVI and some Y/PB/PR jacks, unlike early RCA connections, has bidirectional communication.Quote

What do you mean by bidirectional communication?

They (The TV/cable box and/or recording device) knows when you are using HDMI and either one will know when the other is using HDCP.

I'm sorry can you or some one elaborate here.

Quote It's part of the hardware specification that movie studios lobbied to get built-in to DVD players,set top box , recorders etc. The HDMI /HDCP. signal is secure from point to point, you can't intercept it for recording.Quote

What so you mean by (( HDMI /HDCP. signal is secure from point to point, you can't intercept it))

And what happen with the movie studios lobbied to get built-in to DVD players,set top box , recorders to have HDMI /HDCP. signal.

Can you explain more how HDMI /HDCP works and why it blocks it.

    You have asked the same question at least 5 times so far.

    Different people, including myself, have attempted to answer your question. You seldom respond in any way, but you just turn around and post the same question yet again. And then to top that, you never award any points.

    HDMI is a Bus

    Signals go accross the bus in packets.

    Packets that go over the bus are encoded so that even if you intercept them, you can't decode them.

    Wikipedia has a pretty good description if you want more details.
