摘要： A position sensing system which allows the arthroscopist to readily determine the location of an arthroscope's tip in relation to the point of entry has been developed. The position sensing apparatus can be employed in conjunction with a graphics module to display the location of the arthroscope in real time and provide perspective views of the instrument's location.

摘要： Image encoding apparatus and methods include recursively decomposing the luminance values of sequential frames into spatio-temporal spectral components, by quadrature mirror filter (QMF) processing of the luminance values. The filtered signals are subsampled, and each decomposed level of the spectral components is coded by vector quantization.

摘要： A television encoder for generating a receiver-compatible signal from a production video signal containing enhancement information which cannot be displayed on a standard receiver, the receiver-compatible signal being compatible with the standard receiver, the encoder including a filter bank for dividing the video signal into at least two groups of spatial frequency components including a first group and a second group, the first group containing members which when combined together form a standard video signal which is displayed by the standard receiver and the second group containing the enhancement information; a quantizer for quantizing at least one member of the first group; a combiner for adding at least one member of the second group to a quantized member of the first group to produce a modified first group; and a synthesizer for combining the members of the modified first group to generate the receiver-compatible signal.

摘要： A method of processing video data created for display in one aspect ratio in a plurality of different sequences of frames thereof, each frame in a sequence containing background data which represents at least a part of the same relatively stationary background data in the sequence. The background data in each frame of a sequence is stored and processed so as to produce combined background data representing the background image in the sequence in a different aspect ratio, without the presence of moving objects therein. Data representing moving objects in each frame of a sequence are stored together with selected portions of the background data which surround the moving objects in each frame. The data representing moving objects in each frame are correctly positioned in the combined background data, which is used for each frame of the sequence, by matching the selected portion of the background data surrounding the moving objects with corresponding portions of the combined background data to determine the correct positions of the moving objects in the background image. The background data and the matching portions of the moving objects are composited in accordance with such correct position determination to form a composite image for each frame in which the moving objects are correctly positioned in the combined background image.
摘要翻译：一种处理视频数据的方法，所述视频数据被创建用于在其多个不同的帧序列中以一个宽高比显示，所述序列中的每个帧包含表示该序列中相同相对固定的背景数据的至少一部分的背景数据。存储和处理序列的每个帧中的背景数据，以便以不同的纵横比在序列中产生表示背景图像的组合背景数据，而不存在移动的对象。代表序列的每个帧中的运动对象的数据与围绕每个帧中的运动对象的背景数据的选定部分一起存储。通过将运动对象周围的背景数据的选定部分与组合的背景数据的对应部分相匹配来确定表示每帧中的运动对象的数据位于用于序列的每个帧的组合背景数据中，以确定背景图像中运动对象的正确位置。根据这种正确的位置确定来合成背景数据和运动对象的匹配部分，以形成运动对象在合成背景图像中正确定位的每个帧的合成图像。

摘要： A technique for handling video signals so as to permit such signals to be satisfactorily displayed on video display devices, such as TV receivers or monitors, but to prevent such signals from being satisfactorily recorded by video recording devices. In a particular embodiment thereof the video frame time base is altered in a selected manner, as by lengthening or shortening the time bases of successive video frames, or successive groups of video frames. The alterations thereof can be in discrete steps and be performed cyclically so that during each overall cyclical time period the cumulative error is zero.
摘要翻译：一种用于处理视频信号以便允许这样的信号令人满意地显示在诸如TV接收器或监视器的视频显示装置上的技术，而是防止这些信号被视频记录装置令人满意地记录。在其特定实施例中，通过延长或缩短连续视频帧或连续视频帧组的时基，以选定的方式改变视频帧时基。其变化可以是离散的步骤并且循环执行，使得在每个整个循环时间周期期间累积误差为零。

摘要： Methods and systems for adding additional information to broadcast motion picture signals so that an advanced receiver can decode that information to provide improved picture quality, while a standard receiver will display an image with minimally visible impairments. In particular, chrominance information can be generated at a fraction of the frame rate and the alternate frames then used to encode additional data, such as high definition luminance information in the chrominance signal.
