    • A record and playback system for video information, e.g. video frames successively presented at a standard frame rate, each frame having first and second video fields, and for playing back the video information in a desired sequence to produce a video output signal, providing either slow motion or normal motion effects. A frame recorder has a rotatable recording medium (22), first and second transducer means (24, 25) for recording and playing back video frames in recording tracks on the recording medium. and means (27) rotating the medium at frame rate such that a video frame is recorded in each of the recording tracks. A field store (111) can store a field of video information replayed from the recorder. A switch is connected to a field store and to the recorder for providing at the switch output video information from the field store or the recorder in response to a delay field signal. The switch changes switching state and the transducer means are stepped to provide at the switch output replayed video information in the same sequence in which it was recorded or, alternatively, in a sequence different from that in which it was recorded, with the sequence of fields within the frames properly ordered for interlace. The video recorder system also includes a circuit providing a cue display signal (C-2) on a video monitor which is indicative of the progression of the transducer means to successive tracks during both recording and playback.
    • 用于视频信息的记录和回放系统,例如 连续以标准帧速率呈现的视频帧,每帧具有第一和第二视频场,并且以期望的顺序播放视频信息以产生视频输出信号,提供慢速运动或正常运动效果。 帧记录器具有可旋转记录介质(22),用于在记录介质上的记录轨道中记录和再现视频帧的第一和第二换能器装置(24,25)。 以及装置(27)以帧速旋转介质,使得视频帧被记录在每个记录轨道中。 场存储(111)可以存储从记录器重放的视频信息的字段。 开关连接到场存储器和记录器,以响应于延迟场信号在开关处输出来自现场存储器或记录器的视频信息。 开关改变开关状态,并且换能器装置被阶梯式地提供在开关输出上,以与其被记录的顺序相同的顺序提供重放的视频信息,或者以不同于其记录的顺序的顺序提供 在正确订购交错的框架内。 视频记录器系统还包括在视频监视器上提供提示显示信号(C-2)的电路,其在记录和重放期间指示换能器装置进行到连续轨道。

    • Display apparatus for displaying a series of X-ray images or the like, comprising image storage means (12) such as a video disc recorder for storing a series of images, forward and reverse control means (22, 24) for causing the image storage means (12) to reproduce the images in either a forward sequence or a reverse sequence, label means (26) for producing label number signals to identify each of the stored images, upper and lower limit means (28, 30) for establishing upper and lower limits of the label number signals, upper and lower comparison means (44, 46) for comparing the currently produced label number signals with the upper and lower limits for actuating the reverse control means (24) when the current label number signals correspond with the upper limit and for actuating the forward control means (22) when the current label number signals correspond with the lower limit, and display means (16) for displaying the images reproduced by the image storage means (12), whereby the images are repetitively displayed in forward and reverse sequences between the upper and lower limits.
