An audio-video player, which automatically determines an event corresponding to the current state and displays a preferred message associated with the event, is provided. A DVD player includes: a massage table which stores prescribed messages in advance by associating them with a plurality of events having prescribed priorities; an event determination unit which sequentially determines whether the current state corresponds to an event, starting from an event of higher priority; and a message display control unit which reads out, when the event determination unit found the corresponding event, a prescribed message associated with the corresponding event from a message table and displays it.

Audio-video player and event determination device

When controlling the audio signal to the mute mode from an unmute mode, first, the muting circuit switches from the non-attenuating state to the attenuating state to cause the muting circuit to attenuate the audio signal by the predetermined amount of attenuation, and then, the amount of attenuation by the volume control section is set to the maximum amount of attenuation to cause the volume control section to attenuate the audio signal by the maximum amount of attenuation.

An AV receiveris connected to a DVD player AVPand a CD player AVPvia an IEEE1394 bus. The AV receiverstores a command receiving terminalconnected to a remote controller receiver REas being associated with the DVD player AVP, and a command receiving terminalconnected to a remote controller receiver REas being associated with the CD player AVP. The AV receivertransmits a control command that is received via the remote controller receiver REto the DVD player AVPand a control command that is received via the remote controller receiver REto the CD player AVP

Amplifier connected to and identifying plurality of content reproducing devices with respective audio speakers

PlayersA andB are each capable of outputting data read from a disc such as a CD or an SACD in any of signal formats including an IEEE 1394 format, an analog format and a digital format. An AV amplifierincludes a first output system for selectively outputting, to a speaker systemA, one of a plurality of audio signals of different signal formats including the IEEE 1394 format, the analog format and the digital format, and a second output system for selectively outputting, to a speaker systemB, one of a plurality of audio signals of different signal formats including the analog format and the digital format. If the playerA is selected as the input for the first output system, the AV amplifiersends a command to the playerA instructing the playerA to output an audio signal in the IEEE 1394 format, automatically setting the output signal format of the playerA to be a format that can be reproduced through the first output system.

Audio system, and disc reproduction device and audio output control device for use therein

An AV receiver in an AV system determines the type of connection between the AV system and the display upon receiving a request for an OSD from the user. Based on the result of determination, if the AV receiver is connected to the display through a DVD reproducing device, the AV receiver transmits an OSD request including setting information to the DVD reproducing device. The DVD reproducing device produces an OSD signal based on the setting information and combines the signal with a DVD video signal for output to the display. The display displays video based on the DVD video signal as well as an OSD screen based on the OSD signal. Therefore, the AV system can display settings for the amplifier at the display regardless of the type of connection between the amplifier, the content reproducing device and the display.
