Abstract: In a one-to-many audio wireless transmission system in which a plurality of speaker devices on an audio reception side are provided with respect to one source device, in a case where an error has occurred in a certain speaker device, a possibility of the same error occurring in other speaker devices is reduced. A speaker device (2a, 2b) includes an error detection unit (23) which detects an error regarding sound output and transmits error information which is information regarding an error detected by the error detection unit (23) to a source device (1) by using wireless communication. The source device (1) transmits an operation request corresponding to the error information by using wireless communication to speaker devices other than the speaker device which has transmitted the error information.

Abstract: A relay apparatus (10) is provided with: an image output unit (11); switches (SWa, SWb); a control unit (16) for controlling switches; and an obtaining unit (16) for obtaining a first CEC address associated with the relay apparatus if the relay apparatus is connected to an output apparatus (30). The control unit controls switches to select a signal channel connecting a first signal transmitting device (14) and a storage apparatus (20) if the first CEC address and a reproduction command are received. After connecting the relay apparatus and a unit (40), the control unit controls switches to select the signal channel connecting the first signal transmitting device and a second signal transmitting device (15) if the unit is in a video output state, and controls switches to select the signal channel connecting the first signal transmitting device and the image output unit if the unit is in a standby state.

Abstract: A relay apparatus (10) is provided with a first signal transmitting device compliant with one second signal transmitting device compliant with another standard, a first obtaining device, a second obtaining device, a generating device and a controlling device. If the relay apparatus is connected to an output apparatus via the first signal transmitting device and is connected to a first unit via the second signal transmitting device, the first obtaining device obtains first information about the first unit; a second obtaining device obtains second information about a second unit connected to the output apparatus; a generating device generates third information that allows selection and operation of each of first and second units, on the basis of first and second information, and transmits the third information to the output apparatus; and a controlling device controls the first unit according to a command signal outputted from the output apparatus.
