- Abstract
- Advances in ubiquitous system and service are recently made thanks to the fruition of hardware and software developments so far achieved. The key elements of the ubiquitous services might be the omnipresence of service equipment and the distribution network to provide information to users everywhere. In this sense, satellite network could be one of the most suitable candidates for ubiquitous services in mobile and fixed environment for bi-directional communication and wideband broadcasting network system, which could be the optimal choice for high quality educational information services. This paper analyzes the feasibility of new satellite UHD broadcasting service scenarios using the Ka frequency band while increasing the service availability in Korea. Some countries have started their service trials, and plan to launch commercial broadcasting through a satellite link. For these services, diverse service scenarios should be evaluated to identify the most efficient way to provide the target service on schedule. For this purpose, a rain attenuation analysis was conducted to recognize the amount of expected attenuation in the Korean territory, and the results were applied to the design of the DVB-S2 satellite link. The service scenarios were then analyzed from a variety of aspects considering as many technologies as possible that are expected to be available in the near future. Some of these service scenarios were evaluated for their service availability within the Korean territory through live experiments, the results of which showed that satellite UHDTV service in the Ka band is possible if the proper technologies are selected. This study will be helpful for determining the most reasonable way for other countries preparing similar services at the initial stage, and can contribute to a stable provisioning of UHDTV services in the consumer market.
