Abstract: A light source device includes a mounted substrate which is a multi-layered substrate, a semiconductor light-emitting device which emits a laser beam, a wavelength-converting member which radiates fluorescence by being irradiated with the laser beam emitted from the semiconductor light-emitting device as an excitation light, a state detection circuit, an electric field effect type transistor which adjusts an electric current amount applied to the semiconductor light-emitting device upon receipt of an output from the state detection circuit, and an external connecting member, and the semiconductor light-emitting device, the state detection circuit, the transistor, and the external connecting member are mounted on the single mounted substrate.

Abstract: A sink device is bi-directionally communicably connected to the source device. The sink device includes a first memory, and a controller. Stored in the first memory is a plurality of pieces of audio format information including information representing an audio format that the sink device can process. The controller selects, from among the plurality of pieces of audio format information stored in the first memory, one piece of audio format information corresponding to receiver format information representing an audio format that a receiver device connected to the sink device can process. The controller then outputs the selected audio format information to the source device.
