摘要： The system disclosed herein seeks to solve the problem of unnatural, dizzy camera motion when moving a camera between two preset positions, e.g., head and shoulder shots of two videoconference participants. Particularly, the system described herein attempts to mimic the camera movement that a professional camera operator would use in a professional video production. A preferred method of moving the camera between two positions is to first zoom out, away from the first position, pan across to the next position, then zoom in. This gives viewers of the camera content an idea of the spatial relationship between the two camera positions and also avoids the aesthetically undesirable effect of panning through irrelevant visual background at high zoom ratios. Disclosed herein is a technique of producing this desired behavior in the context of an automatically or semi-automatically controlled video camera, such as those used in conjunction with videoconferencing equipment.

摘要翻译： 本文公开的系统旨在解决在两个预设位置（例如两个视频会议参与者的头部和肩部拍摄之间）移动相机时的不自然的，头晕的相机运动的问题。 特别地，本文描述的系统尝试模拟专业摄像机操作者将在专业视频制作中使用的相机移动。 在两个位置之间移动相机的优选方法是首先将它们从第一位置放大到远离下一个位置，然后放大。这给摄像机内容的观看者提供了两个摄像机之间的空间关系的想法 并且还避免了在高变焦比下通过无关的视觉背景平移的美学上不利影响。 本文公开了一种在自动或半自动控制的摄像机（例如与视频会议设备结合使用的摄像机）的上下文中产生该期望行为的技术。

摘要： Disclosed herein is a system and method for storing and transmitting a videoconference system name (identifier) in the languages of double byte character sets. Although described in terms of a videoconferencing system, the techniques described herein have applicability to various other systems that rely upon inter-language compatibility, including telephonic communication such as cell phones or IP phones, as well as various computer network applications in which computers having different default languages are in communication. In a preferred embodiment, the system identifier is stored in a text or ASCII format rather than native (binary) format. Additionally, a system employing a preferred embodiment of the teachings described herein allows a particular system to have multiple site names in multiple different languages. This allows such a system to interface and exchange identifier data with other systems having different language settings during a caller ID exchange.

摘要翻译： 这里公开了一种用于以双字节字符集的语言存储和发送视频会议系统名称（标识符）的系统和方法。 尽管在视频会议系统方面进行了描述，但是本文描述的技术适用于依赖于语言间兼容性的各种其他系统，包括诸如蜂窝电话或IP电话的电话通信，以及其中具有不同的计算机的各种计算机网络应用 默认语言正在通信。 在优选实施例中，系统标识符以文本或ASCII格式而不是本地（二进制）格式存储。 另外，采用本文描述的教导的优选实施例的系统允许特定系统具有多种不同语言的多个站点名称。 这允许这样的系统在呼叫者ID交换期间与具有不同语言设置的其他系统接口和交换标识符数据。
