Abstract: A relay device includes: a case which holds a mobile terminal, the mobile terminal being attachable to and detachable from the case; a first interface to which the mobile terminal held in the case is connected; a second interface with which the external display device is connected; and a controller housed in the case. The controller includes: an obtainer which obtains a video signal and first notification information from the mobile terminal via the first interface; and a superimposer which superimposes second notification information on the video signal based on the first notification information, and outputs the video signal on which the second notification information is superimposed to the external display device via the second interface. The second notification information is obtained by at least one of deletion or replacement of at least a portion of the first notification information.

Abstract: An acoustic signal processing device includes: a front signal processor which generates first L and R signals by performing signal processing on a first signal which is a front channel signal; a first adder which generates a fourth signal which is a left channel signal by adding the first L signal and a second signal which is a left channel signal; and a second adder which generates a fifth signal which is a right channel signal by adding the first R signal and a third signal which is a right channel signal. The front signal processor generates the first L and R signals by signal processing in which the first signal is distributed and placed at predetermined positions when the first signal is a dialog signal, and distributed and placed at positions different from the predetermined positions when the first signal is not a dialog signal.
