    • A video quality monitoring method includes a distribution server measuring first video quality index values according to a full-reference method by comparing a video, distributed from the distribution server to a client through a network, with a degraded video, generated by causing multiple scenarios of quality degradation due to the network in the video in a pseudo manner, creating characteristic data of first quality degradation values, obtained by causing the quality degradation to vary with the scenarios at regular intervals, and the first video quality index values corresponding to the respective scenarios, and transmitting the characteristic data to the client; and the client measuring a second quality degradation value in the video distributed through the network, and calculating a second video quality index value, equivalent to a value according to the full-reference method, of the distributed video from the measured second quality degradation value and the characteristic data.
    • 视频质量监视方法包括分发服务器,根据全参考方法,通过将通过网络从分发服务器分发给客户端的视频与通过使用多个场景的多个场景生成的劣化视频进行比较来测量第一视频质量指标值 以伪方式由于视频中的网络导致的质量劣化,产生通过使质量劣化以规则的间隔随场景而变化的第一质量劣化值的特征数据,以及与各个场景对应的第一视频质量指标值 并将特征数据发送给客户端; 并且所述客户端测量通过所述网络分发的视频中的第二质量劣化值,并且根据所测量的第二质量劣化值计算与所述全参考方法相对应的分布式视频的值的第二视频质量指标值,以及 特征数据。

    • This invention provides a document management system regarding deleted information for suppressing restoration of information that one does not wish to be referred to again. This invention comprises an electronic document DB device in which a DB is stored and a DB device used for electronic document backup that stores a BDB. When the electronic document to be deleted of the DB stored in the electronic document DB device is indicated, the DMA deletes the electronic document from the DB. Furthermore, when the electronic document is indicated, the DMA deletes the electronic document corresponding to the electronic document in the BDB stored in the DB device used for backup from the DB device used for electronic document backup.
    • 本发明提供一种关于用于抑制再次不想被引用的信息的恢复的删除信息的文档管理系统。 本发明包括其中存储DB的电子文档DB设备和用于存储BDB的电子文档备份的DB设备。 当指定要存储在电子文档DB设备中的要删除的DB的电子文档时,DMA从DB中删除电子文档。 此外,当指示电子文档时,DMA从用于电子文档备份的DB设备中删除存储在用于备份的DB设备中的BDB中对应于电子文档的电子文档。

    • A collapsible type optical unit is described that is capable of moving its optical system between a working position and a retracted position as well as an image-pickup apparatus including the optical unit. The optical unit and the image-pickup apparatus are capable of acquiring lens-position information by detecting a position of a lens barrel supported to be movable with respect to a fixed barrel. The collapsible type optical unit includes a second group lens frame movable along a direction of its optical axis with respect to a fixed ring and rear barrel, and a solid-state image-pickup device provided behind the second group lens frame, in which on the movable second group lens frame, a position-detecting means for detecting a position of the second group lens frame is provided.

    • This invention has as its object to easily verify alterations etc. of files stored in a folder. To achieve this object, an information processing method of this invention is a method of applying hash processing to files stored in a folder, which includes a designation step of designating a folder; a first generation step (steps S601 and S602) of generating hash data for each of files included in the folder designated in the designation step; a second generation step (steps S603 to S609) of generating one multiplexed hash data by repeating multiplexing each of the hash data generated in the first generation step in turn according to a predetermined order; and a step (step S610) of storing the multiplexed hash data in association with the folder designated in the designation step.
    • 本发明的目的是容易地验证存储在文件夹中的文件的改变等。 为了实现该目的,本发明的信息处理方法是对存储在文件夹中的文件应用哈希处理的方法,其包括指定文件夹的指定步骤; 为包括在指定步骤中指定的文件夹中的每个文件生成散列数据的第一代步骤(步骤S 601和S 602) 通过根据预定顺序反复复用在第一代步骤中生成的散列数据中的每一个来产生一个多路复用散列数据的第二代步骤(步骤S 603至S609); 以及与指定步骤中指定的文件夹相关联地存储多路复用的散列数据的步骤(步骤610)。
