    • A display and input method and apparatus providing fully synchronized audio/video information for use with computers and for display on computer-compatible monitors is described. The display and input system includes a computer interface, and provides synchronized digital video and audio input, as well as synchronized digital and analog audio/video output. The display and input system provides synchronization of moving images for display on 72 Hz and 75 Hz computer-compatible monitors. The display and input system facilitates 72 Hz and 75 Hz display of synchronized moving images, such as 24 fps tripled on 72 Hz computer-monitor displays, without using frame dropping or tearing techniques. In accordance with one aspect of the present invention, a "triple-repeat" method (of 24 fps and 25 fps video) is used to provide synchronized display onto 72 Hz and 75 Hz displays, respectively. A "double-repeat" method is used to provide synchronized display of 36 fps and 37.5 fps images on 72 Hz and 75 Hz displays, respectively.
    • 描述了提供与计算机一起使用并在计算机兼容显示器上显示的完全同步的音频/视频信息的显示和输入方法和装置。 显示和输入系统包括计算机接口,并提供同步的数字视频和音频输入,以及同步的数字和模拟音频/视频输出。 显示和输入系统提供运动图像的同步,以便在72 Hz和75 Hz电脑兼容显示器上显示。 显示和输入系统有助于同步运动图像的72 Hz和75 Hz显示,例如在72 Hz计算机显示器显示器上的24 fps为三倍,而无需使用帧丢失或撕裂技术。 根据本发明的一个方面,使用“三重重复”方法(24fps和25fps视频)分别在72Hz和75Hz显示器上提供同步显示。 “双重重复”方法用于分别在72 Hz和75 Hz显示屏上同步显示36 fps和37.5 fps的图像。

    • A method and apparatus for converting picture information. A time code is processed by generating information on whether or not a location is proper to edition when converting picture information of a predetermined system into picture information of another system, and writing the information to time code data accompanied with the picture information of another system. The picture information is converted from a first system to a second. An information reading apparatus reads information about sequential distribution of each frame for generating a field picture in a process of converting picture information of a first system into picture information of a second system whose frame number unit is different from that of the first system by sequentially distributing each frame inside of a predetemined frame number unit of the picture information at plural patterns for generating a field picture. A derived frame removing apparatus removes a derived frame from picture information of a second system. Picture information is transmitted after converting picture information of a first system into picture information of a second system. A procedure for converting picture information of a first system into picture information of a second system is recorded on a recording medium.
    • 一种用于转换图像信息的方法和装置。 通过生成关于当将预定系统的图像信息转换成另一系统的图像信息时的位置是否适合编辑的时间码,并将该信息写入伴随另一系统的图像信息的时间码数据。 图像信息从第一系统转换为第二系统。 在第一系统的图像信息转换为第二系统的图像信息的图像信息的过程中,信息读取装置读取关于用于生成场图像的每帧的顺序分布的信息,该第二系统的帧号单元与第一系统的图像信息不同, 每帧在多个图案中的图像信息的预先设定的帧号码单元内部,用于生成场图像。 派生帧去除装置从第二系统的图像信息中去除派生帧。 在将第一系统的图像信息转换成第二系统的图像信息之后发送图像信息。 用于将第一系统的图像信息转换为第二系统的图像信息的过程被记录在记录介质上。
