• AC Power. All components must be switched on in order for the system to
work. You can't use HDMI connections through the receiver if the receiver is
switched off.
• Anti-piracy. To prevent the piracy of very high quality digital signals, HDMI
also incorporates a security method called High-bandwidth Digital Content
Protection (HDCP). This encrypts the signal so that only authorized devices
can decode the data into pictures and sound. HDMI is for playback only,
meaning that content distributed via HDMI cannot be recorded.
• Super Audio CD. As of January 2005, standards for sending Super Audio
CD sound over HDMI had not been established. For this reason, Super
Audio CD sound is not available over the HDMI outputs of Super Audio CD
players.
HDMI switching and upconversion
The STR-DA7100ES can switch between two HDMI sources and send the
selected signal to a television, using two HDMI inputs and one output. But
there's more. The receiver will also upconvert any composite video, S-Video or
analog component video source to the HDMI digital output. This means your
television can be left on the HDMI input only, with all input source selection done
at the receiver. But it's about more than convenience. It's also ideal for
installations where the television is positioned at some distance from the source
components. In this case, the digital HDMI cable helps protect the video signal
from the "differential gain" and "differential phase" distortions caused by long
runs of analog cable.

Thanks to video upconversion to HDMI, you can have the convenience
of all your home video sources directed to a single output for your
television.
