虚拟演播室多机位特技窗口切换的设计与应用

Design and Application Based on Multi-camera Switching to DVE Windows in Virtual Studio

本文设计了一种虚拟演播室内多机位取景切换至特技窗口的录制形式,利用虚拟机的无轨控制功能实现了有限通道下的多场景制作,通过开发切换台SME级抠像功能制作了通道外的虚拟信号,使导播在节目录制中可独自操作切换台的信号分配与窗口切换。

This article designs a recording format for multi-camera shooting to DVE windows in a virtual studio,which makes multi-virtual scenes under limited channels by using the trackless control function of the virtual reality production system and creating virtual signals outside VR channel by developing SME channel chroma keying of the switcher.It can enable the director to operate the switcher independently for signal selection and windows switching during the programme recording.
