    • A narrow bandwidth broadcasting system for transmission of video and television via low bandwidth medium such as internet or radio links. To save bandwith, video scenes are separated into foreground and background objects and only foreground objects are sent to the viewers. However, graphical model or real image may be sent as a reference background and updated according to its own movement. The broadcast system also captures the video camera identification, position, orientation and field of view size for each video fields and sends it together with the foreground object to the viewer. The broadcast system also includes an object tracking apparatus, which captures the position in space of objects that appear in the scene. Shuch parameters allow the implementation of a 3-dimensional rendering at the receiver side.
    • 一种用于通过诸如因特网或无线电链路的低带宽媒体传输视频和电视的窄带宽广播系统。 为了保存带宽,视频场景被分为前景和背景对象,只有前景对象被发送给观看者。 然而,图形模型或真实图像可以作为参考背景发送,并且根据其自身的移动进行更新。 广播系统还捕获每个视频场的视频摄像机识别,位置,方向和视野尺寸,并将其与前景对象一起发送给观看者。 广播系统还包括对象跟踪装置,其捕获出现在场景中的对象的空间中的位置。 Shuch参数允许在接收机侧实现三维渲染。

    • A method for generating a 3D representation of a scene, initially represented by a first video stream captured by a certain camera at a first set of viewing configurations. The method includes providing video streams compatible with capturing the scene by cameras, and generating an integrated video stream enabling three-dimensional display of the scene by integration of two video streams. The method includes calculating parameters characterizing a viewing configuration by analysis of elements having known geometrical parameters. The scene may be a sport scene which a playing field, a group of on field objects and a group of background objects. The method includes segmenting a frame to those portions, separately associating each portion to the different viewing configuration, and merging them into a single frame.
    • 一种用于产生场景的3D表示的方法,其最初由在第一组观看配置下由某个相机拍摄的第一视频流表示。 该方法包括提供与通过照相机捕获场景兼容的视频流,以及通过集成两个视频流来生成能够进行场景三维显示的集成视频流。 该方法包括通过分析具有已知几何参数的元素来计算表征观看配置的参数。 该场景可以是一个运动场景,一个运动场,一组场上物体和一组背景物体。 该方法包括将帧分割到那些部分,将每个部分分别关联到不同的观看配置,并将它们合并成单个帧。
