The digitalization is the development trend of CATV system. Some new conceptions (such as stereo sound, VOD, time-shifted TV, TV-mail etc.) are introduced into our culture life. The digital CATV system is more and more welcome because of its high-quality AV effect and practical value-added service. According to the requirements for construction of the new generation of aerospace survey ships, we analyze the advantages and disadvantages of the digital cable TV and IPTV, and demonstrate the technologic system the CATV system on aerospace survey ships should be used. According to the ship feature and shipman's requirements, we propose a design about IPTV system scheme on survey ships and describe the basic functions and value-added services this TV system should have.
