Abstract: Each operation screen for jobs to be executed by a multifunction apparatus is layered, according operation steps of the multifunction apparatus, and registered in a distribution server. Menus for displaying the operation screens are also registered in the distribution server, the menus being arranged in a tree-shape configuration. Corresponding to an operation on the multifunction apparatus, the menus are sequentially delivered from the distribution server to the multifunction apparatus, starting from a menu in the top layer. The multifunction apparatus displays each operation screen based on the delivered menus. Menu includes display text (text displayed on the operation screen), next screen name (screen name of the subordinate screen displayed on the operation screen), and action (command for the multifunction apparatus to execute).

Abstract: A multifunction apparatus transmits a menu screen obtaining request and a sort key to a distribution server located on a LAN. Upon receiving the menu screen obtaining request and the sort key from the multifunction apparatus, the distribution server sorts, according to the sort key, the order of menus displayed on the menu screen, and transmits sorted menu screen back to the multifunction apparatus. The multifunction apparatus displays the sorted menu screen, received from the distribution server, on an LCD. When a menu is selected from the displayed menu screen, the multifunction apparatus executes the menu.

Abstract: Menus to be executed by an individual multifunction apparatus are pre-registered in a distribution server for each multifunction apparatus. When the distribution server receives a menu screen obtaining request, a model code, and a sort key from one of the multifunction apparatus, the distribution server accesses a multifunction apparatus menu registration table of the requesting multifunction apparatus and sorts the order of menus according to the sort key. Then, the distribution server transmits the sorted menu screen back to the multifunction apparatus. The multifunction apparatus displays the sorted menu screen, received from the distribution server, on an LCD of a panel. The order of the displayed menus is based on the order specified by the sort key.

Abstract: A multifunction apparatus having at least a printer function and a network communication function is provided with an LCD that displays an input screen where an authentication data is input. When a user inputs authentication data on the input screen, the data is transmitted to an authentication server. The authentication server makes a determination as to permitting the use of the multifunction apparatus and the access to the network, by checking a user table that registers user data authorizing the use of the multifunction apparatus and access data indicating whether the access to the network is permitted. Upon receiving the authentication result, the multifunction apparatus makes a determination as to permitting the use of the multifunction apparatus and the access to the network.

Abstract: A number-of-commands counter counts number of commands received during a predetermined measurement period, which is timed by a timer. An access interval determiner determines command reception frequency from the count result, and decides on an optimum access interval time. An MIB update unit updates <access interval MIB> based on the optimum access interval time. An SNMP agent responds to an obtaining command and transmits <access interval MIB>. An MIB receiver receives <access interval MIB> and an MIB obtainer analyzes <access interval MIB> to recognize the access interval time. A timer setter sets the recognized access interval time at a timer as a timer setting.

Abstract: An input image is digitized. The corresponding digital video data are reproduced while they are successively recorded on a magnetic video device. A successive recording control unit manages at which position of a successive recording area the digital data are to be successively recorded to realize the endless recording in a limitative recording area. When an event occurs, the control unit manages to exclude the recorded image before and after the corresponding event image from the endless recording area so that the event image can be held as an event recording image. Since the monitored image can be reproduced while it is recorded, it can be reproduced timely retroactively, and the image before and after an event occurs can also be reproduced instantaneously. Further, since the recording is continued while the image is reproduced, event images corresponding to plural events can be left.

Abstract: A scene-change detector is disclosed which detects a scene-change of a moving image composed of a plurality of frames. In the apparatus, a moving image is encoded based on the correlation between frames or inside a frame. The energy of an estimation error between frames in the case of encoding is operated by image elements. The energy is totaled by frames, and when the totaled value is larger than a specified value, a signal expressing a scene-change is output.

Abstract: In an optical disk storage, the seek of an optical head is controlled so that the number of seek times cannot exceed a threshold number of times in a predetermined period or an accumulated seek period cannot exceed a threshold period in a predetermined period. Therefore, a wasteful power consumption and a rise in the internal temperature associated with the seek activity can be effectively prevented.

Abstract: The present invention relates to apparatus and method for decoding a signal reproduced from an optical disc. The optical disc has a signal format for recording data from an original signal in a data area at the optical disc. The optical disc also has recorded thereon a clock signal having the same phase as the recorded data. During reproduction of the recorded signal from the optical disc, this clock signal is utilized to generate a delayed version of the reproduced data signal. This delayed signal is used to decode the reproduced data signal obtained from the optical disc, thereby enabling a phase shift of the reproduced clock signal to there produced data signal to be eliminated by circuit processing. During the recording on the data area of the optical disc, fixing data for setting phases of data reproducing recording clock and reproducing signal to optimum phases for decoding is recorded.

Abstract: In an information storage apparatus having an error-correcting code, wherein digital information and check symbols are stored in groups of codewords which are divided into blocks of equal size and a synchronization field for data synchronization is added to each block, a detector detects errors in consecutive synchronization fields when the digital information is read, and a flag-setting circuit sets dropout flags when a signal from the detector indicates an error in consecutive synchronization fields. The flags are set from the last synchronization field that is correctly detected before the error up to the first synchronization field that is correctly detected after the error. In decoding the codewords, the errors in them are corrected with reference to the dropout flags.

Abstract: A separate operational section for determining the degree of a polynomial is provided to increase the process speed in determining both error locator and evaluator polynomials. When a received word is decoded based on the error location found, the received word is stored in a memory and corrected and output through the designation of the address. The formula ##EQU1## is derived from the error locator equation ##EQU2## and the value of which satisfies .sigma.(.alpha.)=0 is determined to increase the process speed. The decoder and the encoder share part of the hardware to make the system compact.
