When an IC card module is used for a small portable information apparatus such as a portable telephone terminal, the module has a size much smaller than an ordinary IC card from the viewpoint that the apparatus is required to be small in size and weight. In the case of a small non-contact type card, there are problems that an antenna coil cannot secure its necessary surface area, a necessary power cannot be obtained for a signal to be transmitted or received, a communication distance from an external device becomes small. When the signal is transmitted and received via a booster coil provided between the external device and the antenna coil of the IC card module, the effective surface area of the antenna coil can be increased and the communication distance can be increased to a level as large as it can practically avoid involvement of any problem.

Practical speaker connection is identified using a device having a sound channel of a 5.1 channel or 7.1 channel, and a device is provided that can easily reproduce the optimum multiple channels. Actual speaker arrangement can be identified by, for example, measuring the impedance of a terminal at the side of an audio amplifier. If incorrect connection is found, a warning is issued. This information is transmitted to a signal source with an EDID and a signal with the optimum a number of sound channel is sent. The EDID is also used for the connection with a display unit and the speaker connection with which the display unit is provided uniquely. For example, a sound through the 7.1 channel is easily reproduced using the speaker of the display unit in the channel of the front speaker.

According to a video information outputting apparatus, a video information receiving apparatus, a video information outputting method and a video information transmitting method, for receiving and outputting digital video information. The digital information is outputted in the same quality as it is, when it is certificated that an external apparatus operates according to a copy control information, while no information limited on copying thereof is outputted when it is not. It thereby prevents the information, which is outputted from the video information outputting apparatus to an external apparatus, from being used in other purposes than the original object thereof, thereby giving disadvantages onto the producer and/or copyright owner of the information.

In a digital information recording/reproducing apparatus, information recorded on a hard disk with copy restriction thereof is protected from being copied onto other hard disks by means of a PC, etc., to be produced a large number of illegal copies, i.e., infringing a copyright.The information is recorded onto a hard disk drive through encryption thereof, with using an identification being number unique thereto, when it is recorded onto the hard disk. With this, normal reproduction is prevented, since the drive identification number necessary for decryption is different from, even if it is copied onto the other hard disk. Also, a version information of the hard disc is memorized in an information management circuit. When the information is illegally copied onto the other hard disc, the version information is changes; therefore it does not coincide with the version information memorized in the information management circuit. With this, illegal reproduction of the information copied can be prohibited in the reproducing operation.

A video processing device includes a control circuit for detecting a physical quantity related to a size of noise contained in the input video signal, and an OSD (On Screen Display) circuit for providing a user with a warning screen when the physical quantity detected by the control circuit is larger than a prescribed value, obtaining an appropriate video signal even when a digital video signal has poor quality.

A steer-by-wire system with a fail-safe mechanism is disclosed in which a clutch for the steer-by-wire system installed between a first shaft connected to a steering wheel and a second shaft connected to a steering gear is formed as a mechanism for bringing about wedgelike engagement of taper rollers by simple operation of turning an operating lever, so that when an abnormality detection sensor detects a defect in the steer-by-wire system, the clutch is operated through a clutch switching actuator to interconnect the first and second shafts and so as to make it possible to directly steer the steering gear.

A magnetic recording and reproducing apparatus wherein a moving picture signal and an audio signal following the moving picture are recorded and reproduced on a first area in a recording track inclined with respect to a traveling direction of a magnetic tape and digital data indicating a one-cut frame or a field) still picture signal is recorded and reproduced on a second area in the recording track. The apparatus includes a circuit for detecting that digital data indicating the still picture is reproduced by an amount of data corresponding to the one-cut still picture, a switch which is operated by a person who monitors pictures and used to instruct restart of the magnetic tape, and a logic circuit. The logic circuit generates an instruction for switching the reproduced signal output from the moving picture to the still picture on the basis of the output of the detection circuit, and instruction for rewinding the magnetic tape to a position near the recording start position of the digital data indicating the still picture and for stopping the magnetic tape thereat, and instruction for switching the reproducing signal output from the still picture to the moving picture signal when the switch is operated, and an instruction for causing the magnetic tape to travel once again at the normal traveling speed for reproducing a moving picture signal.

摘要:
A digital information recording apparatus includes multiple recording circuits for making multiple copies. The apparatus limits the number of copies, however, in accordance with copy information provided within the digital information itself. When the number of copies is reached, if additional copies are to be made, then the source copy is disabled when a new copy is made.
