计算机硬件技术以及计算机可视化和图像生成研究的最近进展对电视制作方法产生显著影响,而这种方法自从彩色电视开始制作以来就很少有变化。在过去十年中,广播界采用的技术特别是录制和后制作领域发生很大变化。现在便用的设备体积比较小、重量较轻、便于携带而且比较灵活。数字技术引入以后,对记录的图像进行操作的可能性实际上已没有限制。 The recent advances in computer hardware technology and computer visualization and image generation research have had a significant impact on television production methods that have changed little since the beginning of color television production. In the past decade, there has been a great change in the technology used by the broadcaster, especially in the field of recording and post-production. Now the equipment used is relatively small, light weight, easy to carry and more flexible. There is virtually no limit to the possibilities of operating on recorded images after the introduction of digital technology.
