Ultra HD Playout & Delivery
Ultra HD Playout & Delivery SOLUTION BRIEF The next major advancement in television has arrived: Ultra HD. By 2020 more than 40 million consumers around the world are projected to be watching close to 250 linear UHD channels, a figure that doesn’t include VOD (video-on-demand) or OTT (over-the-top) UHD services. A complete UHD playout and delivery solution from Harmonic will help you to meet that demand. 4K UHD delivers a screen resolution four times that of 1080p60. Not to be confused with the 4K digital cinema format, a professional production and cinema standard with a resolution of 4096 x 2160, UHD is a broadcast and OTT standard with a video resolution of 3840 x 2160 pixels at 24/30 fps and 8-bit color sampling. Second-generation UHD specifications will reach a frame rate of 50/60 fps at 10 bits. When combined with advanced technologies such as high dynamic range (HDR) and wide color gamut (WCG), the home viewing experience will be unlike anything previously available. The expected demand for UHD content will include all types of programming, from VOD movie channels to live global sporting events such as the World Cup and Olympics. UHD-native channel deployments are already on the rise, including the first linear UHD channel in North America, NASA TV UHD, launched in 2015 via a partnership between Harmonic and NASA’s Marshall Space Flight Center. The channel highlights incredible imagery from the U.S. space program using an end-to-end UHD playout, encoding and delivery solution from Harmonic. The Harmonic UHD solution incorporates the latest developments in IP networking and compression technology, including HEVC (High- Efficiency Video Coding) signal transport and HDR enhancement. -
MMT(MPEG Media Transport)
TECH & TREND 김용한 서울시립대학교 전자전기컴퓨터공학부 교수 TECH & MMT(MPEG Media TREND Transport) 표준의 이해 + 김용한 서울시립대학교 전자전기컴퓨터공학부 교수 MPEG(Moving Picture Experts Group)은 ISO/IEC JTC 1/SC 29/WG 11의 별칭으로서, 디지털 방송, 인터넷 멀티미디어 전송, 멀티미디어 저장 매체 등의 분야에서 널리 활용되고 있는 MPEG-1, MPEG-2, MPEG-4 등의 표준을 제정한 국제표준화 그룹이다. 특히 MPEG에서 제정한 표 준 중에서 ISO/IEC 13818-1이라는 공식 표준번호를 갖고 있는 MPEG-2 시스템 표준은 초기 디지털 방송 방식에서부터 HDTV, DMB 등에 이 르기까지 압축된 비디오, 오디오, 부가 데이터를 다중화하고 비디오와 오디오의 동기화를 달성하며 송신 측에서 수신 측으로 필요한 제어 정 보를 전달하는 방식으로 널리 활용되어 왔다. 올해 제정되고 있는 국내 4K UHDTV 표준들에도 이 MPEG-2 시스템 표준이 채택될 예정이 다. MPEG-2 시스템 표준에 맞게 구성된 비트스트림을 트랜스포트 스트림(Transport Stream, TS)이라 부르는 관계로, 많은 이들이 이 표준을 MPEG-2 TS 표준이라 부르기도 한다. MPEG-2 TS 표준이 제정된 것은 1990년대 초반으로, 인터넷이 아직 글로벌 네트워크로서 일반화되기 전이었다. 당시에는 ATM(Asynchronous Transfer Mode, 비동기 전송 모드)에 의한 차세대 네트워크가 인터넷을 대체하여 새로운 글로벌 네트워크가 될 수 있도 록 여러 나라에서 연구개발 역량을 집중하고 있을 때였다. IP 기반의 네트워크에 비해, ATM 기반 네트워크는 여러 가지 측면에서 최적화된 구조를 가지고 있었음에도 불구하고, 아이러니하게도 이러한 최적화된 기능의 장점을 무색하게 만들 정도로 고속 전송이 가능한 패스트 이 더넷이 출현하면서, IP 기반의 인터넷이 ATM 기반의 네트워크보다 더욱 널리 사용되게 되었고 그야말로 현재 인터넷은 유일한 글로벌 네트 워크가 되었다. 이에 따라 모든 통신망은 IP가 대세인 시대가 지속되고 있다. 급속한 통신 기술의 발전과 환경의 변화로 말미암아 20여 년 전 MPEG-2 TS 표준이 제정되던 때의 환경과 지금의 환경은 너무도 달라졌다. -

Introduction Scene Based Audio is a set of technologies for 3D audio that is based on Higher Order Ambisonics. HOA is a technology that allows for accurate capturing, efficient delivery, and compelling reproduction of 3D audio sound fields on any device, such as headphones, arbitrary loudspeaker configurations, or soundbars. We introduce SBA and we describe the workflows for production, transport and reproduction of 3D audio using HOA. The efficient transport of HOA is made possible by state-of-the-art compression technologies contained in the MPEG-H Audio standard. We discuss how SBA and HOA can be used to successfully implement Next Generation Audio systems, and to deliver any combination of TV, VR, and 360° video experiences using a single audio workflow. 1.1 List of abbreviations & acronyms CBA Channel-Based Audio SBA Scene-Based Audio HOA Higher Order Ambisonics OBA Object-Based Audio HMD Head-Mounted Display MPEG Motion Picture Experts Group (also the name of various compression formats) ITU International Telecommunications Union ETSI European Telecommunications Standards Institute 2. -

Design and Implementation for Media-Aware Transmission Method Based on Mmt
Journal of Theoretical and Applied Information Technology 31st January 2018. Vol.96. No 2 © 2005 – ongoing JATIT & LLS ISSN: 1992-8645 www.jatit.org E-ISSN: 1817-3195 DESIGN AND IMPLEMENTATION FOR MEDIA-AWARE TRANSMISSION METHOD BASED ON MMT 1JONGHO PAIK, 1 SONGYEON LEE, 1 KYUNGA YU 1Department of Software Convergence, Seoul Women’s University, Korea E-mail: 1 [email protected] ABSTRACT Ultra-High-Definition (UHD) broadcasting, which is one of advanced broadcasting technologies, has met the user’s needs for high-definition and realistic services. By the way, UHD content is too large to be transported due to the limited bandwidth of existing HD broadcasting systems. In order to solve this problem, a lot of advanced broadcasting technologies have been suggested. One of the related researches proposed a UHD broadcasting service that each layer of video separated hierarchically are transmitted over heterogeneous networks. Unlike the existing MPEG-2 TS based on stream mode, UHD contents are transmitted based on packet mode. Therefore, to ensure the Quality of Service (QoS) of UHD content against inevitable packet delay, the UHD broadcasting system has to be taken into account the priorities of transmission depending on type of media and the layers of video simultaneously. In this paper, we propose a media-aware transmission method and also experimental results will be shown to verify the effectiveness of the proposed method. Keywords: MPEG Media Transport, Transmission Model, Scheduling, UHD, Hybrid Broadcasting System 1. INTRODUCTION broadcasting system has to be taken into account the priorities of transmission depending on type of As video technology and device media and the layers of video simultaneously [4].
