The media environment is rapidly evolving to be tailored to viewers using personal mobile devices in accordance with technological evolution and changes in social structures. Broadcast media technology is also advancing to enable new services, including data casting, in various reception environments beyond the existing fixed environment and one-way audio/video content services. In addition, technologies to increase the transmission capacity to accommodate next-generation large-capacity media content as well as communication network utilization and convergence technologies are being developed to facilitate interactive services and expand the broadcasting coverage. We discuss the current status and future prospects in broadcasting technology for terrestrial and mobile communication systems and analyze broadcasting technology elements for upcoming media environments relying on generative artificial intelligence.

This study surveys and discusses that to what extent consumers are understanding the benefits and which purpose of use they support more regarding the 700 MHz frequency band allocation for mobile communication use as well as public terrestrial UHD TV broadcasting use. The results of this study can be summarized as follow. First, consumers perceive not only advantages but disadvantages for the decision that 700 MHz frequency band is divided and utilized for both mobile communication and UHD TV broadcasting use. Second, 43% of consumers (the largest portion of opinions) say that they support government's final decision of 700 MHz frequency band allocation, which can be interpreted that government's long term discussion and final decision of frequency allocation policy is favorably accepted by the majority of consumers. The importance of this study is to survey consumers' perception of government's 700 MHz band frequency allocation policy from impartial point of view from either communication or broadcasting interest.
