PLAYBACK CONTROL DEVICE, PLAYBACK SYSTEM, AND METHOD AND PROGRAM FOR CONTROLLING PLAYBACK CONTROL DEVICE

摘要

Provided is a playback system and the like that can accurately output a playback signal, even in the event of an anomaly. This playback system (SY) comprises an information processing device (2) and a controller (1), and is characterized in that the controller (1) comprises a playback signal acquisition unit (51) that acquires a playback signal from an external device (3), a playback signal output unit (54) that outputs the playback signal to an output device (4), an anomaly detection unit (55) that detects an anomaly of an application (25), and a mode switching unit (56) that performs mode switching between a normal mode that outputs the acquired playback signal to the information processing device (2), acquires the playback signal applied by the application (25) and outputs the playback signal to the playback device (4), and a through mode that outputs the acquired playback signal by bypassing the application (25), wherein the mode switching unit (56) switches from the normal mode to the through mode in a case where an anomaly of the application (25) is detected by the anomaly detection unit (55) during the normal mode.
