Although the closed caption broadcasting is provided for almost the whole broadcast time in Korea, the sign language interpretation is not. By translating the closed captions, it is possible to provide three-dimensional (3D) sign language translations for more broadcast time. We propose a sign language broadcasting system for weather forecasts, and extend it for all kind of TV programs. In order to find the frequency of each word, we analysed the last three years' weather forecast scripts, and an opendomain corpus of about 1.2 million words from KBS. We use the Korean wordnet, KorLex, to build the sign language synonym dictionary, and for the word sense disambiguation to improve the translation performance. Optically-captured sign language motions are used for the 3D avatar to present sign language with motion blending. We developed a mobile ondemand sign language weather forecast application, and a real-time sign language interpretation system for all kind of TV programs.
UHD (Ultra High Definition) has been developed and standardized over the past few years and considered as a key of the next generation broadcasting. Since major sporting events that attract many viewers have been good opportunities for applying and promoting new broadcasting technology, KBS (Korean Broadcasting System) has carried out live 4K terrestrial broadcasting of three big sports events in 2014, the KBL (Korean Basketball League) finals, the 2014 FIFA World Cup, and the 2014 Incheon Asian Games. Especially, 4K UHD live coverage of the KBL finals was the world's first live 4K terrestrial broadcasting, and people could enjoy the World Cup and the Asian Games with UHDTV at home. In this paper, the overall live production and data transmission of the sporting events is described, including on-location live production, live HEVC (High Efficiency Video Coding) encoding, SFN (Single Frequency Network) transmission, as well as experimental IP transmission of uncompressed 4K video via KREONET, a national R&D network run by KISTI (Korea
