In electric equipment that has a digital interface, an operation that is normally performed by an output terminal during authentication processing is executed on equipment connected to an input terminal of the digital interface by the input terminal as an erroneous connection detection operation. When there is a proper response from the equipment connected to the input terminal of the digital interface in response to the erroneous connection detection operation, the electric equipment detects that the connected equipment has been erroneously connected. When an erroneous connection is detected, the electric equipment gives notice of the detection of the erroneous connection.

Electric equipment with digital interface and method for controlling the same

In a video playback apparatus that is capable of communicating with a printing device, if an event of which notification is to be given has occurs in the printing device, a situation in which viewing by the user is impeded by the notification and a situation in which unnecessary video is recorded are suppressed. If an error occurs in the printing device, the type of display information prevailing when the error is detected is discriminated (S). In case of a moving-picture program broadcast, an error message is displayed and the display information starts being stored (S), thereby making it possible to resume viewing after error recovery. On the hand, in the case of a still picture or other type of display information, an error message is displayed (S) without storing display information, thereby suppressing unnecessary recording of display information.

The present invention displays a broadcast program without causing discomfort to the viewer caused by a shift in the display position. The burn-in of the display apparatus when displaying EPG and GUI images is prevented. When viewing a channel, the timing of events such as the broadcast start time of the next program and the insertion of CM video are acquired from program attribute information such as the SI and metadata. Information such as the time of the next program or insertion of an advert is detected from the attribute information, and video data that is displayed in the display area of the display unit is changed at that time. The change in video data is executed when setting the area of the video data to be applied to the effective video data area to the display area, by changing the coordinate data of this area.
