Abstract: PURPOSE:To allow the user of a radiotelephony equipment to save a talking charge by allowing a talking unit to apply information display of elapsed time during talking or its relevant information. CONSTITUTION:When an automobile with a radiotelephony equipment mounted on enters the service zone of the public automobile telephone system, a detection output Qns of a data detection section 52 changes from a high to a low level. When the talking state is acquired a little later, a display data Di is sent from a control block 34 and display 45 representing the talking state is given. A detection output signal Qiu obtained from the data detection section 52 attended therewith changes from a low to a high level. Thus, an output signal Qu of an AND gate 54 changes from a low to a high level. Since an output signal Qa is fed to an enable terminal E of a counter 56, the counter 56 starts counting a clock pulse Pc and a count output signal Qc is fed to a data generating section 59. An output data Dx of a data generation section 59 is supplied to a display section 46 and a changing time in following to the content of the count output signal Qc represented by the data Dx is displayed.

Abstract: PROBLEM TO BE SOLVED: To continue recording or reproducing data while securing continuity in the data even when abnormalities happen in recording or reproducing operations such as track jumps.
SOLUTION: If an abnormality detector 30 detects a track jump when recording data on an optical disc 2, data read to the memory 14 is stopped until the operation returns normal based on the detected track jump. When the read is resumed to memory 14, data are recorded on an optical disc 2 seamlessly over the stop time caused by the track jump based on the recording position control of the optical disc 2 by a system controller 7. When reproducing, the data are reproduced from the optical disc 2 continuously regardless of the points of record stop and start.

Abstract: PROBLEM TO BE SOLVED: To provide the reproduction control circuit of a disk player in which a pause function can be realized with simple constitution and also a response corresponding to the operation of a pause key is instantly performed. SOLUTION: When the digital audio compressed data recorded on an optical disk 2 are read out and the audio compressed data are reproduced, a reproduced audio output signal instantly can not be obtained by stopping the reading of the audio compressed data from a memory 22 in accordance with the operation of the pause key in a key entry operating part 8 and, also, when the memory 22 is fully occupied, the reading of the audio compressed data from the optical disk 2 is stopped and the disk player is controlled to be in a standby state. When the pause is released, the reading operation from the memory 22 is resumed.

Abstract: PROBLEM TO BE SOLVED: To provide a reproduction pause circuit of a disk player in which a pause function can be realized with simple constitution, response in accordance with pause key operation can be performed instantly. SOLUTION: When digital audio compression data recorded in an optical disk 2 is read and reproduced, a reproduced audio output signal can be obtained instantly by stopping readout of compressed data from a memory 22 in accordance with operation of a pause key of a key input operation section 8, while reading compressed data from the optical disk 2 is stopped when the memory 22 is filled, and the device is controlled to a standby state. In releasing pause, read operation of the memory 22 is started again.

Abstract: PROBLEM TO BE SOLVED: To exactly identify and process L and R channels by adding identifiers to identify either even sectors or odd sectors to the sectors to be stored and storing these sectors in accordance with the results of discrimination as to whether the stored sectors are the even sectors or the odd sectors. SOLUTION: A memory controller 12 outputs a channel identification signal in order to enable an encoder/decoder section 14 to identify that a sound frame of the two sectors is L channel data at a ratio of once per two sector. For example, the controller emits the channel identification signal at the output timing of the top sound frame of the even sector and has this signal recognized with the L channel by the encoder/decoder section 14. At this time, this identification signal is not outputted in the odd sector. Then, the sound frame is known to be the sound frame of the L channel data captured at the time the identification signal is supplied in the decoder section 14 and thereafter, the processing is successively executed as the R, L and R channels by every sound frame to be captured thereafter and, therefore, the erroneous processing of L as R does not occur.

Abstract: PROBLEM TO BE SOLVED: To prevent copies from being made simultaneously by plural digital audio equipments and to protect data even when the data are transferred among plural digital audio equipments. SOLUTION: In the usual state, a digital signal from an input interface 11 is outputted as it is from an output interface 17, and at the time of recording, a digital signal to be outputted from the output interface 17 is muted. By connecting such functional equipments in series, the danger of making copies by plural digital audio equipment at once can, therefor, be avoided.

Abstract: PROBLEM TO BE SOLVED: To provide a data transmitter capable of protecting data while securing compatibility with the existing digital audio interface. SOLUTION: By using a cable and connections, which are equivalent to an IEC(international electrotechnical commission) 958, an optical connector 6A of one audio equipment 11 is provided with a light emitting element 8A for transmitting an optical signal via an optical cable 1 to a digital equipment on the other party side and a light receiving element 9A for receiving an optical signal sent via the optical cable 1 from the digital equipment on the other party side, while an optical connector 6B of the other audio equipment 12 is provided with a light emitting element 8B for transmitting an optical signal via the optical cable 1 to a digital equipment on the other party side and a light receiving element 9B for receiving an optical signal transmitted via the optical cable 1 from the digital equipment on the other party side. Thus, since interactive data communication can be performed between these audio equipments in a time-division manner, information on encipherment can be transmitted.

Abstract: PURPOSE: To realize more diverse applications by a method wherein, when main data is recorded, information about the main data is recorded as subcode data on a recording medium. CONSTITUTION: A system controller 11 supplies subcode data to an encoder/ decoder part 8 so as to correspond to the EFM encoding operation of main data, and it is recorded inside a main data frame in a disk 1. Even in a magnetooptical region on the disk 1, a Q-channel is used, and various kinds of operations are realized. Then, when a subcode is defined in the magnetooptical region, recording and time stamping by an external timer and character recording in large quantities can be realized as a recording and reproducing apparatus for a minidisk system.

Abstract: PURPOSE:To set a recording mode and a reproducing mode separately before and after a buffer RAM and to cope with an emergency recording, in a recording and reproducing device provided with a buffer RAM. CONSTITUTION:A means 8, 30 for dealing with and processing recording medium enable a reproducing mode operation in which read-out data read out from a recording medium is written in a memory and a recording mode operation in which write-in data written in a recording medium is read out from a memory, to be excuted. Also, input/output processing means 14, 32 being a signal system from a memory to an input/output section of a sound signal enable to perform recording mode operation in which input data inputted to record in a recording medium is written in a memory and reproducing mode operation in which output data read out and outputted from a recording medium is read out from a memory. And, a memory control means 12 enables, write-in or read-out operation in which one of the recording medium-coping and processing means and the input/output processing means is reproduced from a memory as the reproducing mode and the other is recorded in a memory as the recording mode, to be excuted.
