Patent abstract
An apparatus, method and system for connecting High-Definition Multimedia Interface (HDMI) devices. A loopback device connects between a first source device and a sink device on a first connection; a second source device connects to the sink device on a second connection. The loopback device manages the first connection, passes transition-minimized differential signaling (TMDS) or fixed-rate link (FRL) signals through to the sink device, and outputs audio received from the sink device on the audio return channel (ARC) or enhanced audio return channel (eARC). In this manner, audio that originates from any source device may be output without requiring a direct connection to the loopback device.
