Abstract
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.
