  • ATSC 3.0—The Next Step in the Evolution of Digital Television
    • Authors: Richard Chernock;Jerry C. Whitaker;Yiyan Wu;
      Pages: 166 - 169
      Abstract: The goals of ATSC 3.0 are to improve the television viewing experience with higher audio and video quality, compression efficiency, robust transmission for reception on both fixed and mobile devices, and more accessibility, personalization, and interactivity. ATSC is also addressing changing consumer behavior and preferences, providing TV content on a wide variety of devices. Furthermore, ATSC is working to add value to the broadcasting service platform, extending its reach and adding new business models-all without the restriction of backward compatibility with the legacy system. Formal planning for ATSC 3.0 began back in 2010 in a planning team tasked with looking at what a next-generation system might look like. Requirements were subsequently developed based on the usage scenarios. Formal standards development work began in 2012, with the first specification completed and published in March 2016. ATSC 3.0 is being built to last. Technology advances rapidly and so methods to gracefully evolve have been built into the core of the system. An essential capability is to signal when a layer or components of a layer evolve-including the ability to signal minor version changes and updates, and major version changes and updates. The goal of this flexibility is to avoid disruptive technology transitions, and to enable graceful transitions from one technology to another.

  • The Technology Evaluation and Selection Process for ATSC 3.0 Next
           Generation Audio
    • Authors: Jim Starzynski;Skip Pizzi;Paul Thomsen;
      Pages: 170 - 178
      Abstract: The transition from NTSC analog television to the Advanced Television Systems Committee (ATSC) 1.0 digital television (DTV) standard, with its AC-3 audio technology, brought a significant increase in capabilities and enjoyment to television, bringing wide-range cinema-like 5.1 surround sound to the audience. Roughly two decades later, ATSC 3.0 audio is poised to leverage these benefits and add groundbreaking enhancements that include greater efficiency, personalization and immersive surround sound for the listening audience.

      Pages: 179 - 201
      Abstract: AC-4 is a state-of-the-art audio codec standardized in ETSI (TS 103 190 and TS 103 190-2) and included in the DVB toolbox (TS 101 154 V2.2.1 and DVB BlueBook A157) and, at the time of writing, is a candidate standard for ATSC 3.0 as per A/342 part 2. AC-4 is an audio codec designed to address the current and future needs of video and audio entertainment services, including broadcast and Internet streaming. As such, it incorporates a number of features beyond the traditional audio coding algorithms, such as capabilities to support immersive and personalized audio, support for advanced loudness management, video-frame synchronous coding, dialog enhancement, etc. This paper will outline the thinking behind the design of the AC-4 codec, explain the different coding tools used, the systemic features included, and give an overview of performance and applications. It further outlines metadata aspects (immersive and personalized, essential for broadcast), metadata carriage, aspects of interchange of immersive programing, as well as immersive playback and rendering.

Bleidt;Deep Sen;Andreas Niedermeier;Bernd Czelhan;Simone Füg;Sascha Disch;Jürgen Herre;Johannes Hilpert;Max Neuendorf;Harald Fuchs;Jochen Issing;Adrian Murtaza;Achim Kuntz;Michael Kratschmer;Fabian Küch;Richard Füg;Benjamin Schubert;Sascha Dick;Guillaume Fuchs;Florian Schuh;Elena Burdiel;Nils Peters;Moo-Young Kim;
      Pages: 202 - 236
      Abstract: A new TV audio system based on the MPEG-H 3D audio standard has been designed, tested, and implemented for ATSC 3.0 broadcasting. The system offers immersive sound to increase the realism and immersion of programming, and offers audio objects that enable interactivity or personalization by viewers. Immersive sound may be broadcast using loudspeaker channel-based signals or scene-based components in combination with static or dynamic audio objects. Interactivity can be enabled through broadcaster-authored preset mixes or through user control of object gains and positions. Improved loudness and dynamic range control allows tailoring the sound for best reproduction on a variety of consumer devices and listening environments. The system includes features to allow operation in HD-SDI broadcast plants, storage, and editing of complex audio programs on existing video editor software or digital audio workstations, frame-accurate switching of programs, and new technologies to adapt current mixing consoles for live broadcast production of immersive and interactive sound. Field tests at live broadcast events were conducted during system design and a live demonstration test bed was constructed to prove the viability of the system design. The system also includes receiver-side components to enable interactivity, binaural rendering for headphone, or tablet computer listening, a “3D soundbar” for immersive playback without overhead speakers, and transport over HDMI 1.4 connections in consumer equipment. The system has been selected as a proposed standard of ATSC 3.0 and is the sole audio system of the UHD ATSC 3.0 broadcasting service currently being deployed in South Korea.

  • Accessibility in ATSC 3.0 [November (2016)]
    • Authors: Chris L. Homer;Michael A Dolan;
      Pages: 237 - 239
      Abstract: Many people are either hearing or visually impaired or may be completely deaf or blind. Having access to television news, weather, sports, and entertainment requires unique accessibility services. In television broadcast videos can be closed captioned so deaf and hard-of-hearing users can understand the video while Video Description Service can accommodate better understanding of on screen action for the blind or visually impaired. As an emerging platform, ATSC 3.0, can provide an opportunity to improve on these services and offer new ones.

  • ATSC 3.0 Transmitter Identification Signals and Applications
    • Authors: Sung-Ik Park;Wei Li;Jae-Young Lee;Yiyan Wu;Xianbin Wang;Sunhyoung Kwon;Bo-Mi Lim;Heung Mook Kim;Namho Hur;Liang Zhang;Jeongchang Kim;
      Pages: 240 - 249
      Abstract: In the ATSC 3.0 PHY layer standard, a transmitter identification (TxID) signal is defined in order to provide the identification of an ATSC 3.0 transmitter. TxID signal can also be used to find the co-channel and adjacent interference signals, to assist accurate location finding calculation, and to obtain the channel estimation for each transmitter, which can help local service (e.g., targeted advertisement) reception, as well as for emergency alert. For efficient use of spectrum and quality of service improvement, single frequency network (SFN) where all transmitters share a single RF channel is often implemented. The recently developed ATSC 3.0 physical layer standard has been designed to support SFN. For efficient designing, fine-tuning and operating an SFN, it is crucial to identify each transmitter, as well as to adjust transmitting power and emission time of each transmitter. This paper presents TxID for ATSC 3.0, and analyzes its detection performance under very low signal to noise ratio environments and other applications, such as location finding, and channel estimation etc. for each SFN transmitter.

  • Using LDM to Achieve Seamless Local Service Insertion and Local Program
           Coverage in SFN Environment
    • Authors: Wei Li;Yiyan Wu;Liang Zhang;Khalil Salehian;Sébastien Laflèche;Dazhi He;Yao Wang;Yunfeng Guan;Wenjun Zhang;Jon Montalban;Pablo Angueira;Manuel Velez;Sung-Ik Park;Jae-Young Lee;Heung-Mook Kim;

      Abstract: Layered division multiplexing (LDM) is a spectrum efficient non-orthogonal multiplexing technology that has been adopted in the Advanced Television Systems Committee (ATSC) 3.0 Physical Layer Standard as a baseline technology. This paper studies a two-layer LDM with one layer used for providing a global service through a single frequency network (SFN), and the other for providing local coverage/services, such as location targeted advertising or local content insertion. The pilot boosting effect on SNR and co-channel interference is also analyzed. The LDM upper layer can be used to deliver time-division multiplexed mobile-HD and 4k-UHD services. The LDM lower layer with a negative SNR threshold can reliably provide seamless local coverage/service from each SFN transmitter without coverage gaps among adjacent SFN transmitter service areas. No directional receiving antenna is required for the local service reception and receivers simply tune into the stronger signal. In such LDM systems, while the upper layer is operating in a traditional SFN mode, the lower layer operates in a special form of distributed MIMO or gap-filler mode to provide targeted local coverage. For implementing the two-layer system introduced in this paper, only ATSC 3.0 baseline technologies are used, i.e., there is no need to modify the ATSC 3.0 standard. Given the upper and lower layers' data rate requirements and the SNR thresholds, the lower layer power, with respect to the upper layer (injection level), can be optimized to maximize upper and lower layer performance and coverage. Since the advertisement time of the local service is typically less than 20% of the program time, nonreal time could be used to play-back the local content at five times the transmission bit rate for better (audio/video) service quality.

  • Field Test Results of Layered Division Multiplexing for the Next
           Generation DTV System
    • Authors: Sung-Ik Park;Jae-Young Lee;Bo-Mi Lim;Youngmin Kim;Sunhyoung Kwon;Heung Mook Kim;Jeongchang Kim;
      Pages: 260 - 266
      Abstract: In this paper, we present field test results of a layered division multiplexing (LDM) technology for the next generation digital television system, and analyze the results in several scenarios such as rooftop, indoor, and mobile receptions. In order to evaluate performance of the LDM technology, the field strength or the reception power is measured for all considered scenarios. Furthermore, the threshold of visibility, the marginal reception power, and the erroneous second ratio are measured for fixed, indoor, and mobile receptions, respectively. The field test results show that LDM technology enables broadcaster not only to efficiently provide a variety of services (e.g., mobile, indoor, and stationary services) with different robustness within a single radio frequency (RF) channel but also to increase flexible usage of the RF channel.

  • Multiple Service Configurations Based on Layered Division Multiplexing
    • Authors: Jae-Young Lee;Sung-Ik Park;Sunhyoung Kwon;Bo-Mi Lim;Heung Mook Kim;Jon Montalbán;Pablo Angueira;Liang Zhang;Wei Li;Yi-Yan Wu;Jeongchang Kim;
      Pages: 267 - 274
      Abstract: In this paper, we present multiple service configurations based on layered division multiplexing (LDM), which is adopted as a baseline technology of the Advanced Television Systems Committee 3.0 standard. Based on a two-layer LDM technology, a variety of multiple-physical layer pipe (PLP) configurations as well as physical layer framing is introduced depending on the choices of service scenario, time interleaving, and cell addressing. A performance analysis is provided when three different broadcasting services - robust audio, indoor/mobile, and high data rate services - are delivered through different PLPs when a number of broadcasting service scenarios is presented.

  • LLR Reliability Improvement for Multilayer Signals
    • Authors: Cristina Regueiro;Jon Barrueco;Jon Montalban;Pablo Angueira;Juan Luis Ordiales;Manuel Velez;
      Pages: 275 - 281
      Abstract: The limitations and rigidness of current use of spectrum resources have fostered the design of new power multiplexing techniques to improve frequency efficiency and flexibility. These techniques are based on the simultaneous transmission of different services on the same channel with different power distribution. At the receiver side Log-likelihood ratio (LLR) probability density functions have been so far optimized for single layer systems, so the reception quality of multilayer signals with the existing LLR algorithms is degraded. This paper proposes a new LLR probability density function, including corrections for the multilayer influence, in order to improve reception performance. Simulation results are also included to test the performance improvement in terms of the receiving SNR threshold.

  • Scattered Pilot Performance and Optimization for ATSC 3.0
    • Authors: Eduardo Garro;Jordi Joan Gimenez;Sung Ik Park;David Gomez-Barquero;
      Pages: 282 - 292
      Abstract: The next-generation U.S. digital terrestrial television (DTT) standard ATSC 3.0 is the most flexible DTT standard ever developed, outperforming the state-of-the-art digital video broadcasting-terrestrial 2nd generation (DVB-T2) standard. This higher flexibility allows broadcasters to select the configuration that better suits the coverage and capacity requirements per service. Regarding the selection of pilot patterns, whereas DVB-T2 provides eight different patterns with a unique pilot amplitude, ATSC 3.0 expands up to 16, with five different amplitudes per pattern. This paper focuses on the pilot pattern and amplitude performance and optimization for time and power multiplexing modes, time division multiplexing and layered division multiplexing (LDM), respectively, of ATSC 3.0. The selection of the optimum pilot configuration is not straightforward. On the one hand, the pilots must be sufficiently dense to follow channel fluctuations. On the other hand, as long as pilot density is increased, more data overhead is introduced. Moreover, this selection is particularly essential in LDM mode, because the LDM implementation in ATSC 3.0 requires that both layers share all the waveform parameters, including pilot pattern configuration. In addition, there is an error proportional to the channel estimate of the top layer that affects to the lower layer performance.

      Abstract: Gallager's decoding algorithms B (GDB) and E (GDE) for low-density parity-check codes have much lower computational complexity and much less required memory size than the sum-product algorithm (SPA). This is because GDB and GDE only use binary or integer operations, while the SPA requires real operations and a look-up table. However, they are hardly used in commercial communication systems since they have a worse performance than the SPA. Layered-division multiplexing (LDM) is considered in ATSC 3.0 in order to deliver multiple broadcasting streams with distinct robustness in a single radio frequency channel. Due to the unique characteristic of the LDM, we propose to use GDB or GDE rather than the SPA for decoding the core layer signal at fixed receivers. Numerical results show that the computational complexity and the required memory size can be reduced without any performance loss by about 50 percent and 80 percent, respectively, when GDB and GDE are employed.
