摘要： In order to prevent a reduction in frame rate of a reproduced moving picture on the terminal equipment side for performing a display and enable moving picture playback under a simple construction in a remote display technology, either a server or a terminal equipment or both thereof are equipped with router-attached graphics engines. The server draws a window and decoration thereof into a virtual VRAM, calculates the difference in the drawn data, performs a first decode process as a pre-process, adds drawing position information to intermediate data obtained in the first decode process, and transmits moving picture stream data to the terminal equipment. The terminal equipment effects a second decode process used as a post-process on received data, and draws and displays the so-process data in accordance with the drawing position information.

摘要： 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.

摘要： Before original information is recorded in areas such as a recording medium management area where the same pattern of information is recorded many times, a dummy pattern that minimizes a recording film flow is recorded. Because the direction of the recording film flow depends on the length of a mark length, the dummy pattern is a pattern including marks with a unique length. Randomly or sequentially selecting and recording a plurality of dummy patterns, each with a recording film flow direction different from others, prevents jitters, which will be caused by the recording film flow, from increasing.

摘要： In a wobble signal detecting circuit provided by the present invention, a wobble signal is converted into binary data before being supplied to a PLL circuit by way of a polarity switching circuit and a clock switching circuit. The PLL circuit outputs a recording/playback timing generation clock signal. The frequency of the recording/playback timing generation clock signal is divided by a frequency dividing circuit before being fed back to the PLL circuit. A difference in phase between the wobble signal and the feedback signal is detected by a phase inversion detecting circuit and, if the difference in phase exceeds a phase difference determined in advance, the phase inversion detecting circuit generates a polarity switching signal for switching the polarity of the wobble signal. The polarity switching signal is used to invert the polarity of the polarity switching circuit.

摘要： A MCAV optical disc read/write system with a postscript type of recording medium is disclosed, which uses a pit edge method of recording information in spiral physical tracks of the medium. The spiral physical tracks are grouped into logical tracks in which a single track address is assigned to each logical track. The logical tracks in turn are grouped into circumferential zones. The number of physical tracks constituting a logical track in adjacent circumferential zones, and the number of track sectors per logical track are set such that the increment in the number of sectors per physical track in proceeding from an inner one to an outer one of such zones is controlled to minimize rate changes in the read/write clock frequency at zone boundaries. Sector addresses thereby may be read even when a read/write head is positioned in a wrong one of adjacent zones.

摘要： In case of rewriting data by means of an erasable optical disc memory recording new data after having erased a series of data already stored, directory data written in an optical disc memory in order to control the written data are transferred to an external directory memory and write-in and read-out are controlled by using the directory memory. For rewriting data, which have been already recorded and which are recorded under a specified file name, the data are not erased and renewed data are written in another recording region, where recording is possible. The data, which have become unnecessary as the result of renewal, are erased during a period of time, when the optical disc memory is not accessed.
