    • A map update system includes a map server in which map information created by map database information stored in a map information database is hierarchized according to the area size of the map information and stored. If map information of a lower hierarchy required for an upper hierarchy or a navigation device is updated, update is reported to the navigation device. Moreover, if the map database information is updated, map information assigned to a hierarchy in accordance with the importance of the place and building indicated by the updated portion of the map database information is updated.
    • 地图更新系统包括地图服务器,其中根据地图信息的区域大小对存储在地图信息数据库中的地图数据库信息所创建的地图信息进行分层并存储。 如果更新了上级或导航装置所需的较低级别的地图信息,则向导航装置报告更新。 此外,如果更新地图数据库信息,则更新根据由地图数据库信息的更新部分指示的地点和建筑物的重要性分配给层次结构的地图信息。

    • A picture display unit for moving picture retrieval based on multi-scene reproduction. The picture display unit comprises a picture reducing section for reducing picture data, a picture combining section for combining the reduced picture data to produce a combined picture, a picture displaying section for displaying the combined picture, and a simultaneous multi-scene reproducing section for taking the charge of reproduction of picture data. The picture reducing section reduces the picture data in units of frames to be reproduced, and the picture combining section combines the reduced picture data belonging to the same frames of the picture data, and the simultaneous multi-scene reproducing section reproduces this combined picture. This arrangement allows the effective use of the computer rescue and the improvement of the moving picture retrieval efficiency.
    • 一种用于基于多场景再现的用于运动图像检索的图像显示单元。 图像显示单元包括用于减少图像数据的图像缩小部分,用于组合缩小图像数据以产生组合图像的图像合成部分,用于显示组合图像的图像显示部分和用于采集的同时多场景再现部分 图像数据的再现费用。 图像缩小部分以要再现的帧为单位减少图像数据,并且图像合成部分组合属于图像数据的相同帧的缩小图像数据,并且同时多场景再现部分再现该组合图像。 这种安排允许有效利用计算机救援和提高动态图像检索效率。

    • In a CATV-LAN in which a plurality of modems transmit messages asynchronously from respective terminal apparatuses to an upstream transmission path and receives messages from a downstream transmission path, when a modem is transmitting a message, the resultant data which are received by that modem are compared with data of that message which have already been transmitted, and transmission is interrupted if the received data do not correctly match the transmitted data, due to conflict with data transmitted by some other modem. Each message contains information specifying its length, and when a non-transmitting modem receives a set of data whose actual length does not match a length value which is specified within the data, the data are discarded. It thereby becomes unnecessary to provide beat detection circuits in the modems, for detecting data conflict, so that system cost can be reduced.
    • 在其中多个调制解调器从各个终端装置异步发送消息到上游传输路径并且从下游传输路径接收消息的CATV-LAN中,当调制解调器正在发送消息时,由该调制解调器接收的结果数据是 与已经发送的消息的数据进行比较,并且如果由于与某些其他调制解调器发送的数据的冲突,如果接收到的数据不能正确匹配发送的数据,则传输被中断。 每个消息包含指定其长度的信息,并且当非发送调制解调器接收到其实际长度与数据中指定的长度值不匹配的数据集合时,数据被丢弃。 因此,不需要在调制解调器中提供差拍检测电路,用于检测数据冲突,从而可以降低系统成本。
