Abstract: When a remaining battery power amount of a child appliance is lowered, a battery recharging operation of the child appliance is not quickly carried out, lowering of the remaining battery power amount of the child appliance is displayed on a mother appliance which is owned by a mother. When there is a risk that the remaining battery power amount of the child appliance is lowered and thus operations of the child appliance will be brought into a malfunction condition, a content of a special instruction is stored into a non-volatile memory employed in the child appliance. Otherwise, while the content of the special instruction has been stored in a management server, an operation may be carried out in response to the instructed response after the remaining battery power amount has been recovered to a sufficiently high battery power amount.

Abstract: In a remote monitoring system, when a guardian inputs predetermined authentication data to a master terminal in order to make a request for authentication of the master terminal, the authentication data is transmitted to a firm server via a base station and a cellular phone network. The firm server 15 compares the authentication data with reference data in a registration data file for authentication of the master terminal to execute authentication decision. When the guardian operates keys of a slave operation section 31 to operate the slave terminal remotely from the master terminal, a command signal for causing the slave terminal to perform a desired operation is transmitted form the master terminal to company facilities and temporarily held therein.

Abstract: The present invention relates to a video signal processing apparatus for outputting an inputted video signal after subjecting the video signal to time axis correction, particularly to a video signal processing apparatus preferable in the case of subjecting the video signal to image compression. In the case in which a nonstandard signal is inputted to an image compression circuit of an MPEG2 encoder or the like, a drawback of freezing image or generating block noise or the like is resolved. A time axis correcting circuit stores an input signal to a memory and reads the input signal at a timing delayed from V synchronization of the input signal by a predetermined time period. For that purpose, a read synchronizing signal generator is reset at respective input field. A reset position is set to a position preceding the read V synchronization position by 3H through 10H.

Abstract: For horizontal sync information HD suitable for use in image processing module, e.g., module for TBC features, image compression recording/playback features, and LCD displaying features, it would be desirable that the time base fluctuations of the video input signal is faithfully reflected and that an interpolated HD generating feature is provided. A module for generating pulses generates the trailing edges of Csync as the trailing edge HD, and switches to an interpolated HD when a dropped pulse is detected after a few microseconds delay in the leading edge relative to the standard pulse. Thus, the trailing edge HD is selected within a time base fluctuation on the order of a few microseconds and the time base fluctuation is faithfully reflected and interpolation features can also be provided.

Further, by properly controlling an onscreen-display on a monitor display screen or a display on a VTR display tube, the operating efficiency is further improved.
