    • 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。
