An information display apparatus having a display unit that displays first information based on a signal corresponding to one channel in a broadcast wave received by a receiving unit, further includes a detecting unit that detects a reception state of the signal while the first information is displayed on the display unit; a judging unit that judges whether information displayed on the display unit has been changed from the first information to second information, if the reception state of the signal has deteriorated; a monitoring unit that monitors whether the reception state has returned to a favorable state, if the displayed information has been judged to have been changed to the second information; and a display control unit that continues display of the second information and redisplays the first information on a portion of the display unit, if the reception state of the signal has returned to a favorable state.

Information display device, information display method, information display program, and recording medium

A broadcast receiver has a GPS reception section for clocking, a TV tuner for receiving a broadcast wave of TV broadcast, and a display for displaying video information of a program transmitted by a broadcast wave, and displays video information of a plurality of programs received on a single screen of the display at the same time every hour on the hour. Accordingly, the user (viewer) can check the program contents of channels that can be received at the time of day.

In a digital acoustic reproducing apparatusfor selecting and outputting one sound information from a sound information sourcehaving plural kinds of sound information with at least the number of channels or different data formats, there are provided sound information readout memberfor reading sound information out of the sound information sourceinformation acquisition memberfor acquiring information about data formats capable of decoding by a decoderto which the sound information read out is supplied or information about the number of speakersto which the sound information decoded by the decoderis supplied, and sound information selection memberfor selecting sound information to be outputted to the decoderbased on the acquired information.

Digital acoustic reproducing apparatus, acoustic apparatus and acoustic reproducing system

An information recording medium reproducing system has an insertion opening, a recording medium storing portion and a medium carrying device. Photodetectors are provided for detecting passing of the recording medium and for producing a passing signal when the medium passes. A controller is provided for controlling operation of the medium carrying device. The controller applies a discharge signal to the medium carrying device when the passing signal is not produced within a predetermined time, whereby the medium carrying device is actuated in discharge operation.

Information reproducing system having means for preventing a breakdown thereof caused by abnormal conditions

A drive controller for controlling to change the orientation of a display surface of a display in accordance with the seating position of occupants aboard a vehicle. A display unit is rotatably mounted on a vehicle. A controller automatically rotates the display unit to a first position where the display surface is oriented toward a driver seat, when an occupant is seated solely in the driver seat. The controller rotates the display unit to a third position where the display surface is oriented toward a front passenger seat, when an occupant is seated solely in the front passenger seat. The controller rotates the display unit to a second position where the display surface is oriented toward the middle point between the driver seat and the front passenger seat, on detecting both of the occupants are seated respectively in the driver seat and the front passenger seat.

Drive controller and control method

A display controller for controlling display on a display surface of a display unit mounted on a vehicle. The display unit is rotatably mounted on the vehicle. A CPU of a controller recognizing that the vehicle is traveling, that a display surface of a display unit is oriented toward the driver's seat, and that a moving picture is displayed on the display surface, inhibits display of the moving picture on the display unit. The CPU of the controller, recognizing that the vehicle is traveling, that the display surface of the display unit is oriented toward the driver's seat, and that a moving picture is displayed on the display surface rotates the display unit to a position where an occupant of the driver's seat cannot watch the moving picture.

Display controller, display control method, drive controller and drive control method

An information playback apparatus which can perform scan playback capable of being performed with finer settings. When a unit cycle B and a playback time A within the unit cycle B are specified and the start of the scan playback of playback data recorded in a DVD is specified, playback control data having address information and information of the playback order appended to each piece of data in the smallest basic units of the playback data is read out from the DVD, whereby the scan playback of the playback data is performed by managing the playback time A in every unit cycle B. Also, when access-inhibited data is present within the playback data, the scan playback of playback data is performed except the access-inhibited data.

System for reproducing information recorded on an information recording medium

An apparatus for detecting the absence or the presence of the occurrence of the abnormal insertion that a plurality of disc bodies each of which should be inserted separately one by one are inserted consecutively, provided with: a passing detecting device for detecting the passing of the disc body, mounted on the passing route of the disc body, and a determining device for determining the occurrence of the abnormal insertion if the detecting device detects the passing again after the detecting device detected the passing once.

Apparatus and method for detecting abnormal insertion of disc body

A first detector is provided for detecting an optical disc inserted in an opening of a reproducing system and for producing a first signal, and a second detector is provided on a reproducing device for detecting the disc carried to the device and for producing a second signal. A sensing circuit is provided for sensing a temporary reduction of a voltage of power supplied to the system and for producing a temporary reduction signal. A control means is provided to be responsive to the first signal and to the temporary reduction signal for operating a carrying device to carry the disc in an unloading direction, and in a loading direction when the disc reaches a predetermined position.

System for reproducing recording mediums

A disc reproducing apparatus is provided which is adapted to scan information tracks to read information recorded on an information recording medium. This disc reproducing apparatus comprises: determining means capable of determining an actually happened track jump, said determining being effected when a difference between a present reproducing positional information and a reference reproducing positional information is larger than a predetermined value; detecting means for detecting a present track position which is just being reproduced at a present time; and setting means for setting said predetermined value corresponding to the present track position, in accordance with a result of the detecting means.

Disc reproducing apparatus for determining a track jump

A system for reproducing recording mediums has a reproducing device, a storing device for storing a plurality of recording mediums, a moving device for relatively moving the reproducing device and storing device for reproducing a recording medium. A controller is provided to be responsive to a command for operating the moving device for positioning the reproducing device and the storing device at predetermined fixable initializing positions.
