New services such as OTT have appeared, and the value chain of the media industry has formed a complex terrain, and new problems have arisen in terms of fair competition between operators and user protection. However, the problem of introducing OTT under the existing law that classifies services by physical characteristics and technical elements of the network has been criticized in terms of hindering industrial activation due to excessive regulation. The introduction of the new regulatory system has been delayed for a long time despite the dissatisfaction of stakeholders and attempts to legislate

The number of domestic users of OTT services is gradually increasing, and users can consume content more freely through OTT services that can consume content in various ways unlike existing broadcasting systems. As the service utilization rate increases and consumption patterns diversify, useful and convenient UI design and usability should be considered from the user's point of view, but research on the app UI design of OTT service is still insufficient. Therefore, in this study, UI design components were compared and analyzed for the top five mobile apps in Korea's OTT platform utilization rate, and usability evaluation was conducted through surveys and in-depth interviews with 10 people in their 20s. Based on the analysis results, the direction of improvement of OTT service mobile apps in the future was presented, and the results of this study are expected to be used as basic data for improving UI design and usability of OTT mobile apps in the future.

According to the Korea Information Society Development Institute, OTT services grew at a rate of 33.4% in four yearsfrom 2017, when they were first launched.TheKorea Export-Import Bank announced in 2020 that the domestic OTT market was worth 780.1 billionKRW. This growth of the OTT market is expected to stimulate competition among OTT service platforms, and user satisfactionwithconvenience features, such as video recommendations, seems to be acting as an important factor in the competition.Currently, the OTT market uses a variety ofdata for customized recommendations, but the limitationis that it only uses datacollected within the app. Thereby we have proposed the use ofpersonal data collected outside the app for personalized recommendations, and the survey results showed that user satisfaction was 23.72% higher for recommended content based on the proposedmethod thanNetflix recommended content.

망관리성이란 다수의 이용자가 네트워크를 효율적으로 이용할 수 있도록 하기 위해 통신사업자가 네트워크를 합리적으로 관리할 수 있어야 한다는 것을 의미한다. 본고에서는 최근 증가하고 있는 대용량 비디오 트래픽에 대한 최적의 이용환경을 제공하고 망관리성을 제고하는 방안으로서 비디오 트래픽 대역폭 최적화 동향을 살펴보고 향후 방향을 제시하고자 한다. 비디오 트래픽 대역폭 최적화란 네트워크(3G/ LTE 등), 단말(휴대폰/태블릿 등), 콘텐츠(스포츠/드라마/영화 등) 유형별로 이용자의 동영상 품질 만족도와 네트워크 품질을 동시에 만족하는 최적 대역폭(비트레이트)의 비디오 트래픽을 전송하는 것이다. 비디오 트래픽 최적화에 있어서 최적대역폭 선정 기준의 정립은 다음과 같은 두 가지의 연구 결과를 기반으로 진행된다. 첫째, 일반적으로 동영상 대역폭이 증가할수록 영상 품질도 정비례로 증가할 것이라는 예상과는 달리, 무선 단말 이용자는 영상화질의 일정 임계치 이상에서 품질의 차이를 거의 느낄 수 없다. 둘째, 다량의 비디오 트래픽이 네트워크 총 대역폭의 일정 비율 이상을 차지하게 될 경우 네트워크 품질저하 요소가 발생하여 네트워크 품질이 급격히 악화된다. 비디오 트래픽 최적화는 이러한 요소를 고려하여 이용자의 영상 품질 만족도를 최대화하면서 네트워크 품질 유지비용을 최소화하고 트래픽 전송품질을 확보할 수 있는 최적대역폭을 설정하는 것이다. 비디오 트래픽 최적화의 목적은 트래픽을 통제하거나 차단하는 것이 아니며 최적대역폭에 대한 가이드라인을 제시하여 콘텐츠사업자(이하 CP)와 Over-The-Top 사업자(이하 OTT)가 자발적으로 준수하도록 유도하고자 하는 것이다. 비디오 트래픽 최적화는 ICT생태계 모든 이해관계자에게 편익을 제고할 것으로 기대된다. 첫째, 이용자에 대해서는 통신품질 안정화로 전체적인 이용자 만족도를 향상시킨다. 둘째, CP/OTT는 멀티미디어 서비스의 대중화와 서버 및 전송장비 비용을 절감할 수 있다. 마지막으로 통신사는 네트워크 품질저하 및 비용 급증을 방지할 수 있다.
