• 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. Digital HDMI : Up-conversion : Down-conversion : Through Analog Component S-Video Composite 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.
