Abstract:
1. An optical disk player comprising: an optical pickup which reads out signals from an optical disk by irradiating a laser beam on the optical disk; a signal processing means which processes the signals read out by the optical pickup; a signal decoding means which decodes the signals processed by the signal processing means; an HDMI (High-Definition Multimedia Interface) output terminal to which an HDMI cable is connected and outputs the signals decoded by the signal decoding means to outside of the player through the HDMI cable; and a control means which controls the optical pickup, the signal processing means, and the signal decoding means, wherein when an appliance is connected to the HDMI output terminal through the HDMI cable, the control means obtains information of sampling frequency or frequencies that the appliance supports; when the connected appliance does not support audio output, no audio signal is outputted from the HDMI output terminal; and when the connected appliance supports the audio output, and also when an audio sampling frequency of a sound source recorded in the optical disk is larger than the audio sampling frequency or all of the sampling frequencies that the connected appliance supports, the audio signals decoded by the signal decoding means are down-sampled to have the sampling frequency or one of the sampling frequencies that the connected appliance supports, and then, the down-sampled audio signals are outputted to the connected appliance.
