Infrared control signals are repeated and communicated in a system including a source device and a sink device that are communicatively coupled by a serial communication link that includes a forward channel and a backward channel. Modulated infrared remote control data is detected by an infrared detector without de-modulation, and sampled in modulated form. Sampled data corresponding to the modulated remote control signal is transmitted from the sink device to the source device over the serial communication link, which in one example is a single optical fiber. The source device receives the sampled data and regenerates the infrared control data, which is then used to control the operation of the source device.
