Abstract

An AV device is provided that can automatically perform OSD display setting of other AV devices at a time based on local ODS display setting even when a plurality of AV devices are connected. The AV device (depicted as TV 1) includes a connection means (depicted as an HDMI connector 21 and an HDMI connector 22) for making connection with external AV devices 3 and 4 capable of performing OSD display, an OSD processing portion 23 for performing OSD display on a display 17, and a system controller 20 for controlling the entire system. The OSD processing portion 23 generates ODS display setting data 23a from the display setting such as a character color and size in OSD display received from a user using a TV remote controller 2 or the like and stores it. The system controller 20 transmits the OSD display setting data 23a for the TV 1 stored here to the external AV devices 3 and 4 via the HDMI connectors 21 and 22.

Dependent claims

An AV device including a connection portion for connecting external AV devices capable of performing OSD display and an OSD display portion for performing OSD display on an external display device or an internal display device, comprising:

a display setting portion for receiving display setting in the OSD display portion;
a setting data generation portion for generating and storing OSD display setting data to be applied at the OSD display portion from display setting received by the display setting portion;
a setting data transmission portion for sending the OSD display setting data for the AV device stored by the setting data generation portion to the external AV devices through the connection portion;
and
an external setting data generation portion for generating, from the OSD display setting data for the AV device stored by the setting data generation portion, OSD display setting data for the external AV devices that has different display setting content from the OSD display setting data, wherein
the setting data transmission portion sends OSD display setting data generated by the external setting data generation portion to the external AV devices, instead of the OSD display setting data for the AV device.
