; Repeater: A repeater accepts content, decrypts it, then re-encrypts and retransmits the data.
It may perform some signal processing, such as upconverting video into a higher-resolution format, or splitting out the audio portion of the signal.
Repeaters have HDMI inputs and outputs.
Examples include home theater audio-visual receivers that separate and amplify the audio signal, while re-transmitting the video for display on a TV.
A repeater could also simply send the input data stream to multiple outputs for simultaneous display on several screens.
