1. A reception apparatus comprising:
circuitry configured to
receive a first stream including image and audio data from an external device by a main link reception unit,
process the received audio data in synchronization with an audio clock generated based on dividing ratio information for obtaining the audio clock from a link video clock,
transmit a second stream including encoded data capable of clock recovery in synchronization with a carrier clock generated by the reception apparatus based on the generated audio clock to the external device by a sub link transmission unit,
receive a command from the external device by the sub link transmission unit to switch to the carrier clock generated by the reception apparatus, and
decode the received audio data based on the carrier clock generated by the reception apparatus for output by the reception apparatus,
wherein the circuitry determines a process of switching to the carrier clock according to a determined mode of operation.
