Abstract: 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.

Abstract: 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 (S34). In case of a moving-picture program broadcast, an error message is displayed and the display information starts being stored (S35), 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 (S310) without storing display information, thereby suppressing unnecessary recording of display information.

Abstract: A communication control device in an audio visual device system has disconnection detection unit for detecting that an audio visual device is disconnected from the audio visual device system, device detection unit for detecting an audio visual device which has not acquired a logical address according to a device type, and control unit for performing control for causing the audio visual device without a logical address to acquire a logical address, when disconnection of a audio visual device is detected by the disconnection detection unit. With this configuration, in an audio visual device system in which an upper limit is set to the number of logical addresses according to a device type, it is possible to cause an audio visual device which cannot acquire a logical address according to the device type to acquire a logical address when it is made available.

Abstract: 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.

Abstract: A receiver for detecting a predetermined SD broadcast program transmitted at a high speed using an HD broadcast channel, storing the detected predetermined program in a storage, and reproducing a broadcast signal of the predetermined program stored in the storage at a speed faster than the normal reproduction speed.

Abstract: Even when a user leaves from a TV apparatus or enjoys audio-visual contents by another reached TV apparatus, the user can enjoy the left audio-visual contents without being embarrassed in operating the reached TV apparatus. A configuration is set up by having leaving information detection means for detecting the leaving information form the user, storage means for storing the image data after detecting the leaving information, and transmission means for transmitting said image data to the reached TV apparatus of the user so that the user is allowed to enjoy the left audio-visual contents and the like in the left TV apparatus by the reached TV apparatus.

Abstract: An image processing apparatus for performing image processes corresponding to input signals of multiple types, includes a luminance correcting unit that performs correction process on an input signal so as to correct for display luminance, a luminance decreasing unit that multiplies the input signal with a gain smaller than “1”, and a gamma correcting unit that performs gamma correction with a gamma value smaller than “1” on the input signal. The luminance decreasing unit and the gamma correcting unit are combined together to execute a first correction process that decreases a luminance of a highlight portion of an image while maintaining or increasing the luminance of a halftoned portion of the image, and the luminance decreasing unit executes a second correction process that decreases the luminance for substantially overall tone levels of the image.
