    Abstract: A video layer effects processing system which receives normal video and special effects information on separate layers has been presented. The system selectively mixes various video layers to transmit a composite video signal for a video display such as a television, or a virtual reality system. Special effects include spotlights, zooming, etc. Additional special effects such as shaping of objects and ghost effects are created by masking and superimposing selected video layers. The selective mixing, for example, to enable or disable, strengthen or weaken, or otherwise arrange special effects, can be directed from a remote source or locally by a user through real-time control or prior setup. The video layer effects processing system can also be incorporated into a set-top-box or a local consumer box.

    Abstract translation: 已经提出了在单独的层上接收普通视频和特殊效果信息的视频层效果处理系统。 系统选择性地混合各种视频层以传送用于诸如电视或虚拟现实系统的视频显示的复合视频信号。 特殊效果包括聚光灯,缩放等。通过屏蔽和叠加所选的视频图层,可以创建其他特殊效果,如对象成像和重影效果。 例如,通过实时控制或事先设置,可以从远程源或用户当地指导选择性混合,例如启用或禁用,加强或削弱或以其他方式排列特殊效果。 视频层效果处理系统也可以并入机顶盒或本地消费盒中。

    Abstract: A video processing system includes at least one video source, a region selecting unit, a subtracting unit and a display unit. The region-selecting unit selects the user-defined region of interest from the video source. The subtracting unit subtracts the required region, selected by the region selecting unit. The output of the subtracting unit is provided to the display unit, which displays the required output. In one embodiment, when video data is received from a plurality of video sources, the selecting of user defined regions of interest from the video sources is supported. The region subtracting unit can be used to subtract the required region of interest from video data and it is displayed on the display unit. In other embodiments of invention, the display unit displays on overlay of two unrelated video streams.
