摘要： A mini disc (MD) player has the capability of displaying data without problems during playback. When plural mini discs should be played back consecutively, TOC (table of contents) data are read from all of these discs. Then, the discs are played back in succession. When compressed audio data derived from these discs are stored in a DRAM, a disc identification flag is added to every disc.

摘要： A signal recording/reproducing apparatus having both bar-type and numeric signal-level displaying units which can be easily read. The apparatus includes a sample-and-hold circuit for sampling and holding an input signal at a first predetermined rate, a first display unit for displaying in bar form the sample values sampled by the sample-and-hold circuit, a data holding circuit for sampling and holding the sample values periodically at a second predetermined rate, and a second display unit for numerically displaying the sample values selected by the data holding circuit. The bar code display can change at a rapid rate to dynamically follow the input signal, while the numeric display changes at a slower rate so as to allow the user sufficient time to comprehend the numerically displayed value.

摘要： A doorphone system includes a relay station. A doorphone master station and a relay station are wirelessly connected, and the relay station and the cordless extension master station are wirelessly connected. A wireless communication link between the doorphone master station and the cordless extension master station is established via the relay station. Namely, all of the wireless communication between the doorphone master station and the cordless extension master station is executed via the relay station. The above doorphone system can effectively enlarge the communicatable range between the doorphone master station and the cordless extension master station. By using a cordless phone instead of the relay station, a system formed by combining the doorphone system and the cordless phone can be easily formed.

摘要： A telephone answering attachment to a highfidelity music system. An adaptor switches audio signals between a telephone circuit, a double-deck recorder and an amplifier. A bell signal on the telphone circuit causes one deck to play a back a prerecorded message onto the telephone circuit and causes the other deck to then record the caller's message. A short notification message is displayed on a television screen. Otherwise, the adaptor leaves the double-deck recorder in its usual configuration.

摘要： A high speed information retrieval apparatus that carries out program retrieval and reproduction on the basis of program numbers used as subcodes corresponding to individual information programs recorded on the magnetic tape. Two high speed search operations are used in moving the tape from a current position to an object position. A memory is used to store code representations of program positions, and a position information calculation circuit determines tape position based on a detection of tape reel rotation. In one high speed search mode, the memory and calculation circuit output are compared to determine position. In another high speed search mode, the subcode on the tape is compared to a current tape position. When the object program number is stored in the memory, the mechanism block is set to a second high speed running mode by a control circuit. The block stays in that mode until the current tape position comes within a threshold distance of the object position. When the object position is not stored in the memory, or the threshold distance is reached in the second mode, the mechanism block is set to a first high speed running mode.

摘要： In a signal reproducing device such as an R-DAT video tape recorder, a digital signal recorded on the recording medium is reproduced by the magnetic head, stored in a memory, processed by a processing circuit, and converted into an analog signal by a D/A converter, and a detector detects whether or not the reproduction signal outputted by the head is present so that, according to the output of the detector, a muting circuit mutes the digital-to-analog converted signal and a driver suspends the operation of a level meter adapted to display the level of the digital signal, whereby the production of noise signals and the abnormal display of signal levels are prevented.
