To a video display device, a remote control transmitter for remotely operating the video display device is attached. When at least one of predetermined keys provided in the remote control transmitter of an external device is operated, the video display device switches, according to the setting of an 'input target', the validness and the invalidness of an remote operation on the at least one of predetermined keys of the external device which outputs a video stream to the video display device.

Video display device and external device

An electronic device having a clock portion for counting time and having the time on the clock portion set based on time information acquired from outside has a notification portion that communicates information of the time counted by the clock portion to an external device via a physical line. Alternatively, an electronic device has a first clock portion counting time and an acquisition portion that acquires, from an external device having a second clock portion for counting time and having the time on the second clock portion set based on time information acquired from outside, information of the time counted by the second clock portion via a physical line, and the time on the first clock portion is set based on the information acquired by the acquisition portion.

Electronic device related to automatic time setting

A picture display device including a display unit which displays a picture in accordance with a picture signal included in a broadcast signal. A display control unit displays a picture for an electronic program guide including characters on the display unit in accordance with program information included in the broadcast signal. A brightness information retriever retrieves information related to the brightness of the picture displayed on the display unit. The display control unit adjusts the size of the characters in the electronic program guide displayed on the display unit in accordance with the brightness information retrieved by the brightness information retriever.

Picture display device

An electronic device has a plurality of wired-connection terminals, a selection portion that selects one of the plurality of wired-connection terminals for input of source data, and a transmission portion that wiredly transmits a command requesting a shift to a normal-operation mode to another electronic device having a power-save mode after switching of input by selection by the selection portion. The plurality of wired-connection terminals are all of an identical type for wired connection to another electronic device having a power-save mode.

In a broadcast signal receiving apparatus, a remote controller has, as one of a plurality of buttons thereof, a state changing button for instructing to change a source to be reproduced by a main body. The main body or the remote controller has a memory storing a first state changing table indicating an order in which the source is changed. When the state changing button is operated, if the broadcast signal is being received by the tuner portion and reproduced as the source, the main body performs state change such that the first source in the first state changing table is specified as the source to be reproduced by the main body.
