Abstract

The broadcasting communications service will accelerate its development with the convergence of broadcasting media and internet service. In the field of CATV network related technology, only those service providers will be able to survive in future, and they can combine available services in the most effective and economical way. This research aims to explain the CATV status of Korea and China and its technology trends. It also analyzes CMC(Cable Modem Concentrator) technology, suggested as one of the high-speed internet technology. CMC technology has the advantages of enhancing the transmission speed while using the existing basic structure of HFC network and expanding service area by adding amplifiers within CMC. The distance between coaxial cables is getting shorter with more concentrated areas in large cities in Korea. However, in China, the demand for long distance transmission service is increasing. CMC technology satisfies both short and long distance service subscribers without any geographical limitations. With these advantages, CMC technology is expected to generate lots of economic benefits if applied for the CATV network in the area of China, Middle East, and Southeast Asia.
