Since the video documentary team is not yet available for this, I get shanghaied into operating Nick's personal digital Handycam.

因为视频录制组还没有到，因此我糊里糊涂地就被拉去操作尼克的私人便携式数字监控器。

The digital watermarking technique, which is a new technique for protecting the copyright of the digital products occurring in recent years, is a hot point of the research of international academic circlers at present.

近年来，数字化技术和Internet的飞速发展，在最大限度地拓宽权利人利益范围的同时，也带来了版权保护的危机。由于图像、视频、音频和其他作品都能以数字形式获得，其拷贝非常容易，从而可能会导致大规模非授权拷贝，而这极有可能会损害音乐、电影、书籍和软件等出版业的发展。
