随着数字网络技术的不断发展与完善,电视系统及其外围设备的数字化和网络化已成必然。我台早在1996年就投入使用了由大恒公司基于PROFILE硬盘录像机开发的广告播出系统,但是由于当初的系统设计受客观条件制约,系统和设备的拓展及升级能力已达极限。即便如此系统仍然难以适应信息高速时代广告播出的多重需要。 With the continuous development and improvement of digital network technology, the digitization and networking of the television system and its peripheral devices have become inevitable. As early as 1996, I put into use the advertisement broadcast system developed by Daheng based on PROFILE DVR, but due to the original system design was restricted by the objective conditions, the expansion and upgrade capability of the system and equipment reached the limit. Even so, the system still has difficulty adapting to the multiple needs of broadcasts in the high-speed information age.
