目前非线性制作网络系统和播出的结合通常有两种形式：采用网络直播和输出后录播。录播方式是把制作完成的节目通过音视频接口输出到录像带或视频服务器上,然后使用录像机或视频服务器进行播出。由于这种形式的输出需要把信号转换到基带,然后进行录制或重新编码,所以对信号质量会有损失。如果采用 SDI 信号输出,图像质量损失相对较小。 At present, the combination of non-linear production network system and broadcast usually has two forms: the network broadcast and post-broadcast. Recording and broadcasting is to produce the finished program through the audio and video interface output to the video tape or video server, and then use the video recorder or video server to broadcast. Since this form of output requires the signal to be converted to baseband and then recorded or recoded, there is a loss of signal quality. If using SDI signal output, image quality loss is relatively small.
